Getting started with WebRTC natively is no easy picnic. The goal of webrtcbuilds is to provide a single standalone WebRTC static library and package.

webrtcbuilds

The goal of webrtcbuilds is to provide a single standalone static library and package for WebRTC.

Current Platforms and Prerequisites

• OSX (requires Homebrew is installed)
• Windows (requires Visual Studio Community 2013 at least and a Bash shell such as Git for Windows is installed)
• Linux (tested on Ubuntu 16.04 64-bit)

How to run

./build.sh to build the latest version of WebRTC.

Or with options.

Usage:
   ./build.sh [OPTIONS]

OPTIONS:
   -h             Show this message
   -d             Debug mode. Print all executed commands.
   -o OUTDIR      Output directory. Default is 'out'
   -b BRANCH      Latest revision on git branch. Overrides -r. Common branch names are 'branch-heads/nn', where 'n' is the release number.
   -r REVISION    Git SHA revision. Default is latest revision.
   -t TARGET OS   The target os for cross-compilation. Default is the host OS such as 'linux', 'mac', 'win'. Other values can be 'android', 'ios'.
   -c TARGET CPU  The target cpu for cross-compilation. Default is 'x64'. Other values can be 'x86', 'arm64', 'arm'.
   -n CONFIGS     Build configurations, space-separated. Default is 'Debug Release'. Other values can be 'Debug', 'Release'.
   -e             Compile WebRTC with RTTI enabled. Default is with RTTI not enabled.
   -g             [Linux] Compile 'Debug' WebRTC with iterator debugging disabled. Default is enabled but it might add significant overhead.
   -D             [Linux] Generate a debian package
   -F PATTERN     Allow customize package filename through a pattern
   -P PATTERN     Allow customize package name through a pattern
   -V PATTERN     Allow customize package version through a pattern

The PATTERN is a string that can use the following tokens:
   %p%            The system platform.
   %to%           Target os.
   %tc%           Target cpu.
   %b%            The branch if it was specified.
   %r%            Revision.
   %sr%           Short revision.
   %rn%           The associated revision number.
   %da%           Debian architecture.

Where is the package

out/webrtcbuilds-<rev>-<sha>-<target-os>-<target-cpu>.zip where <rev> is the revision number of the commit, <sha> is the short git SHA of the commit, and <target-os>-<target-cpu> is the OS (linux, mac, win) and CPU (x64, x86) of the target environment.

undefined reference to `cricket::DeviceManagerFactory::Create()'

Hi!
I'm trying test DeviceManagerFactory,but getting link errors.

Test Code:

#include <iostream>

#include "webrtc/base/scoped_ptr.h"
#include "talk/media/devices/devicemanager.h"

int main(int argc, char **argv) {
    rtc::scoped_ptr<cricket::DeviceManagerInterface> dev_manager(
            cricket::DeviceManagerFactory::Create());
    if (!dev_manager->Init()) {
        std::cout << "Can't create device manager" << std::endl;
        return 1;
    }
    std::cout << "Created device manager" << std::endl;
    return 0;
}

Options for compiling examples

Hi vsimon,

Could you provide some command line options for compiling examples, like AppRTCMobile?

To build the android demo, in util.sh, I commented out the line in patch() method which removes the example from being built, and add AppRTCMobile target in the compile-unix(), and finally I got an apk.

Thank you very much!

Difference between Debug and Release

Hi vsimon

I came across a problem which took me 3 weeks to find what code always cause segfault.
Though i have work hard on it, i only found the debug and release versions are different and i still don't know what the diff is.
Finally i build a simple test here and i cannot move forward one step:

#include <memory>
#include <iostream>
#include "webrtc/base/thread.h"
#include "talk/media/base/videocapturer.h"

using namespace std;
using cricket::VideoCapturer;

class GangVideoCapturer: public VideoCapturer {
public:
    GangVideoCapturer() {
    }
    cricket::CaptureState Start(const cricket::VideoFormat& capture_format) override {
        return cricket::CS_STOPPED;
    }
    void Stop() override {
    }
    bool IsRunning() override {
        return false;
    }
    bool IsScreencast() const override {
        return false;
    }
    bool GetPreferredFourccs(std::vector<uint32>* fourccs) override {
        return true;
    }
};

void run() {
    cout << "run start" << endl;
    VideoCapturer* capture = new GangVideoCapturer();
    cout << "create capturer ok" << endl;
    delete capture;
    cout << "delete capturer ok" << endl;
}

int main(int argc, char **argv) {
    run();
    cout << "quit" << endl;
}

Install linux deps from webrtc instructions

Started from a discussion here: #20 (comment)

May want to call sudo ./build/install-build-deps.sh instead.

build fails when building ios arm arm64

Hi

running this command

./build.sh -d -o build_ios -r 185ba29a3c0556798158840c2424416d0fd779fe -t ios

I keep on getting this error

warning: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: archive library: libwebrtc_full.a will be fat and ar(1) will not be able to operate on it /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: for architecture: x86_64 file: libwebrtc_full.a(atomicops_internals_x86_gcc.o) has no symbols /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: for architecture: x86_64 file: libwebrtc_full.a(atomicops_internals_x86_msvc.o) has no symbols /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: for architecture: x86_64 file: libwebrtc_full.a(error_listener.o) has no symbols /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: for architecture: armv7 file: libwebrtc_full.a(debug.o) has no symbols /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ar: internal ranlib command failed

I tried googling it but nothing panned out, would you have any idea, your help would be much appreciated,

thanks

No sound on mac

When I run the same code on windows everything works, I have sound when I have a voice conversation with a webrtc page in chrome. However, when I build the same app on Mac and try to make a call I get silence on mac (both ways). All signalling exchange is correct, except I simply don't get any audio, as if some dev/null is used for wavein/waveout on mac. Any ideas/pointers where I should look into?

Thanks

I tried to delete the line but it is back each time the build process run.
Anybody got some idea to fix it?

For cross-compiling android via target_os="android" target_cpu="arm"
Or iOS.

DataChannel Only Target

Hey, thanks for your efforts on this script, it really is a life saver.

It seems recently the ability to build with DataChannel only was added, it would be awesome if this could be added as a target for the script.

I use WebRTC in a server like environment where browsers can connect, so there is no need for audio/video. Having a slimmer library would save even more headache (and size).

Also are you accepting donations?

Fail to compile peer_connection example

Hi vsimon
I've been trying to compile, adding dependancies that are missing from the wiki page on how to compile peer_connection, and I've come to the following error compiling with gcc

/usr/bin/ld: /home/usr/Documents/webrtcbuilds/out/webrtcbuilds-26473-fa89d84-linux-x64/lib/Release/libwebrtc_full.a(psnr.o): undefined reference to symbol 'log10@@GLIBC_2.2.5'
/lib/x86_64-linux-gnu/libm.so.6: error adding symbols: DSO missing from command line

to which i have no idea how to handle.
Compiling with g++ gives several undefined references to webrtc:: and json:: also.

Fail to compile on mac

on current mac, building with specific build is failing due to usage of --lines and --fields.

REVISION=$(git ls-remote $REPO_URL --heads $BRANCH | head --lines 1 | cut --fields 1) || \

simple change to this works

REVISION=$(git ls-remote $REPO_URL --heads $BRANCH | head -n 1 | cut -f 1) || \

Example of how to include webrtc_full.lib in a Visual Studio project

Hi,

Thanks for this great project !
Following my question on the mailing list: https://groups.google.com/forum/#!topic/webrtcbuilds/AhjHnOO_CCI, I was wondering if it would help anyone to have an example of how to link a build of WebRTC with a C++ Visual Studio project.

I ended up having a webrtc_full.lib static library without too much trouble, however being more of a Linux guy I am having trouble to link it against my Visual Studio project.

I would be glad to propose a pull request to complete the wiki about how to compile peerconnection example on Windows once my problem will be fix. https://github.com/vsimon/webrtcbuilds/wiki/Building-the-peerconnection-example

Thanks again for this great script !

how to compile webrtc？

can u tell me how to compile webrtc？ I've tried countless times for several months, but I failed.. I follow the official instructions, I've tried njnia or vs2013... there were various problems. :(
i need linux32 too,so that i can work with andorid device.i just want android device communicate to pc(both linux and windows).

there is my email [email protected], thank you sooooooooooooo much!!!

PeerConnection client wiki post does not behave correctly. Cannot compile

The basic instructions for building the WebRTC PeerConnection client on Linux no longer appears to work.

I did try to assemble a Makefile version. But that ends up failing with a couple unresolved symbols.

It seems that simd_asm.lib is not packaged into webrtc_full.lib

Hi,

I create a Visual Studio project, and link against webrtc_full.lib,
error like this:
webrtc_full.lib(jsimd_x86_64.obj) : error LNK2019: 无法解析的外部符号 jsimd_rgb_ycc_convert_sse2，该符号在函数 jsimd_rgb_ycc_convert 中被引用

When I add link library simd_asm.lib, build successfully.

It seems that simd_asm.lib is not in webrtc_full.lib and need link separately.

Subclass link error

Hi vsimon!
I got a lot link errors recently. I finally locate the problem after testing.
When extending subclass from some webrtc class ie rtc::Thread, g++ will say undefined reference to `typeinfo for rtc::Thread'.

Code:

#include <iostream>
#include "webrtc/base/thread.h"

class GangCapturerThread: public rtc::Thread {
public:
    explicit GangCapturerThread() {
    }
    virtual ~GangCapturerThread() {
    }

    void Print() {
        std::cout << "ok" << std::endl;
    }
};

int main(int argc, char **argv) {
    GangCapturerThread thread;
    thread.Print();
}

Command:

g++ ./main.cc    `pkg-config --cflags --libs --define-variable=prefix=/home/savage/soft/webrtc/webrtc-linux64 libwebrtc_full` -o "ic-webrtc"

Error:

./main.o:(.rodata._ZTI18GangCapturerThread[_ZTI18GangCapturerThread]+0x10): undefined reference to `typeinfo for rtc::Thread'
collect2: error: ld returned 1 exit status

Another Test:

#include <iostream>
#include "webrtc/base/thread.h"

int main(int argc, char **argv) {
    rtc::Thread* thread = rtc::Thread::Current();
    std::cout << thread->IsCurrent() << std::endl;
}

Everything's ok!
I've no idea what's wrong with the subclass.

Build with Third_Party Json?

I see the flag WEBRTC_EXTERNAL_JSON inside of the webrtc headers. However I can not use it because the third_party headers are not included. Is it possible to compile webrtc with these third_party headers? I am having a lot of problems with my systems jsoncpp library.

Support for Screen Sharing

Hello There,
Will you ever have support screen sharing with an example for OSX native world?

Appreciate your effort.

Thanks!

Is there a mailing list/developer forum?

Is there a mailing list or similar for asking questions on how to use webrtcbuilds?

(btw @vsimon thanks an awful lot for making this project - you have saved us a lot of pain.)

Build problems under Microsoft Windows

The Microsoft Windows build does not work for me. I have created a fork to fix the problems, and will post a pull request when done. If someone can provide a little help with a problem regarding depot_tools listed under 'Next problem', I would appreciate it.

Problems fixed so far:

• Platform detection (util.sh function set-platform): the (recommended) git bash shell returns an $OSTYPE value of 'msys' (mingw). Added detection of $OSTYPE 'msys', set PLATFORM to 'windows'.
• curl output directory creation (util.sh function check::deps): the 'curl' command to load jq.exe fails to create the output directory, even with --create-dirs specified. Added an explicit 'mkdir --parents', this fixed the problem.

Next problem:

• depot_tools, fetch command (util.sh function checkout): the 'fetch' command is not found. This may result from an interaction between util.sh functions check::depot-tools and check:deps. check::deps creates the depot_tools directory to load python276_bin/jq.exe, so check::depot-tools finds that the depot_tools directory already exists, and does not load the tools. I would appreciate any suggestions about how to fix the handling in a clean manner.

Because chromium/src is transitioning to Git (from SVN), we needed to
change the way that the WebRTC standalone checkout works. Instead of
individually syncing subdirectories of Chromium in SVN, we're now
syncing Chromium (and all of its DEPS, as defined by its own DEPS file),
into the `chromium/src` directory.

As such, all Chromium directories which are currently pulled by DEPS are
now replaced with a symlink into the full Chromium checkout.

To avoid disrupting developers, we've chosen to not delete your
directories forcibly, in case you have some work in progress in one of
them :).

ACTION REQUIRED:
Before running `gclient sync|runhooks` again, you must run:
src/setup_links.py --force

Which will replace all directories which now must be symlinks, after
prompting with a summary of the work-to-be-done.

Building with GN instead of GYP

Does it make sense to transition the build to using GN instead of GYP? @agouaillard mentioned the issue in his comment on pull request #18.

Alex referenced the Google+ discuss-webrtc PSA by Henrik Kjellander https://groups.google.com/forum/?fromgroups#!topic/discuss-webrtc/QMJBvIn1Y3o (as I write this, updated 12 hours ago), which states that all builds other than iOS now use GN instead of GYP.

Presumably, updating to GN might be a problem for people building older revisions of WebRTC.

Thoughts?

Consider adding a config option for rtti/no-rtti builds

Currently, the builds are forced to rtti.

Cross compiling

I'm trying to cross compile WebRTC to Windows on a Linux machine. This requires a win_toolchain. I used this script to produce the toolchain.

The toolchain is stored as a zip file. I was wondering if there is a way to feed this toolchain to the build.sh script as input.

Chromium instruction on cross-compiling is not clear how to use the toolchain.

Build problems on OSX

1. checking for the absence of variable via -v MSVSVER does not work with the 'nounset' option on non-windows platforms.
2. readlink on osx does not have an -f option.

Console:

dev_manager->GetVideoCaptureDevices(&devs)
Enumerating V4L2 devices
V4L2 device metadata found at /sys/class/video4linux/
Found V4L2 capture device /dev/video0
Trying /sys/class/video4linux/video0/name
Name for video0 is Loopback video device 0
Total V4L2 devices found : 1

I found that this line causes the exit after debug: devicemanager.cc#L360

  for (std::vector<Device>::iterator it = devices->begin();

called by: main()

bool has = dev_manager->GetVideoCaptureDevices(&devs);

So i replaced that line to:

        const char* const kFilteredVideoDevicesName[] = {NULL, };
...
    devs.clear();
    devs.push_back(cricket::Device("Loopback video device 0", "/dev/video0"));

    bool has = cricket::DeviceManager::FilterDevices(&devs,
            kFilteredVideoDevicesName);

Then got error:

Then i google again and again, but still found nothing.
Can you help me again?Thanks!

Script fails trying to install ancient "apache2.2-bin" package (apache2-bin is new name)

The package, apache2.2-bin, is not avaliable in Debian stable (buster) or Debian oldstable (stretch). It is only available in oldoldstable (jessie) or in older unsupported historical archives.

Even in jessie, the package does not do anything. It just has a dependency on apache2-bin. It's a transitional package for upgrading to jessie from even older versions. Unfortunately, it pins the version, so that it wants to install the ancient apache2-bin from jessie, which conflicts with installing an up-to-date apache.

The dependency should simply be changed to apache2-bin. Nothing will break unless someone tries to build it on a Debian-based system even older than jessie.

This is from the log of the build. I included a lot of context; the error is at the bottom.

Build problems under Microsoft Windows

The Microsoft Windows build does not work for me. I have created a fork to fix the problems, and will post a pull request when done. If someone can provide a little help with a problem regarding depot_tools listed under 'Next problem', I would appreciate it.

Problems fixed so far:

• Platform detection (util.sh function set-platform): the (recommended) git bash shell returns an $OSTYPE value of 'msys' (mingw). Added detection of $OSTYPE 'msys', set PLATFORM to 'windows'.
• curl output directory creation (util.sh function check::deps): the 'curl' command to load jq.exe fails to create the output directory, even with --create-dirs specified. Added an explicit 'mkdir --parents', this fixed the problem.

Next problem:

• depot_tools, fetch command (util.sh function checkout): the 'fetch' command is not found. This may result from an interaction between util.sh functions check::depot-tools and check::deps. check::deps creates the depot_tools directory to load python276_bin/jq.exe, so check::depot-tools finds that the depot_tools directory already exists, and does not load the tools. In general, 'git clone' requires an empty directory, so the approach of loading jq.exe before calling git clone does not work. I would appreciate any suggestions about how to fix the handling in a clean manner.

Building with GN on Windows

Fix any issues building with GN on Windows.

Automatic `apt-get -y install` should use `--no-upgrade`

When apt-get -y install is used by automated installers, they should use --no-upgrade. Users probably aren't expecting to have their systems upgraded by this build script, and it is unlikely ever to be needed.

(Even if it were needed to get a specific version, the current approach would be inadequate, since users might not have the updated apt sources. The correct approach would be generating a package with dependencies with version bounds, then installing that.)

Am I missing some Mac foundation packages here?

Looking an example of using the prebuilt Android libraries

I know Android support is still experimental, but is it working for some people?
I want to build an Android native library (.so file) which uses WebRTC's peer connection layer to enable p2p media streaming. I haven't been able to figure out how to incorporate the prebuilt Android libraries into my Android.mk file.
For one thing I'm not sure which of the supplied libraries (libwebrtc_full.a, libjingle_peerconnection_so.so, or libwebrtcdemo-jni.so) I should be linking to. I've been betting on the libjingle_peerconnection_so.so library, but keep on getting undefined symbols for all of the symbols in the rtc namespace.

The test code I am trying to compile (into an .so) is

#include "talk/app/webrtc/peerconnectionfactory.h"

extern "C"
{
void foo()
{
    rtc::Thread *worker = new rtc::Thread;
    rtc::Thread *signaling = new rtc::Thread;
    worker->Start();
    signaling->Start();
    rtc::scoped_refptr<webrtc::PeerConnectionFactoryInterface> peerConnectionFactory = 
        webrtc::CreatePeerConnectionFactory(worker,signaling,0,0,0);
}
}

Thanks

Fix errors building x86 on linux

Probably needs libexpat1-dev:i386 somewhere in deps (webrtc's install-dep scripts doesn't cover?)

$ ./build.sh -c x86
