tools-android's Issues

GNUstep sources are built without optimization and debug info

Because we export CFLAGS in our scripts, tools-make does not use the default -g -O2 usually returned by Autoconf and sources to be built without optimizations.

x86 build fails due relocation linker error against libffi on x86

With the latest libffi v3.4.3 update we get the following linker error:

 Linking library libgnustep-base ...
ld.lld: error: relocation R_386_PC32 cannot be used against symbol open_temp_exec_file; recompile with -fPIC
>>> defined in /build/x86/lib/libffi.a(closures.o)
>>> referenced by closures.c
>>>               closures.o:(dlmmap_locked) in archive /build/x86/lib/libffi.a
clang++: error: linker command failed with exit code 1 (use -v to see invocation)

The libffi issue contains more details.

Error when building against API level < 28

A recent change in libdispatch causes the toolchain build to fail when the minimum API level is < 28 as noted here.

We need to up our API level or add a patch for libdispatch.

Build failure in libcurl with NDK r26

libcurl/lib/formdata.c:796:10: error: call to undeclared function 'fseeko'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  return fseeko(stream, (off_t)offset, whence);
         ^

This error was also discussed in curl/curl#12086.

release version should include ndk version information

nice to have

Building libxml2 fails

Building the toolchain fails with the following error:

### Updating project
From https://github.com/GNOME/libxml2
* [new branch]        mainline   -> origin/mainline
Your configuration specifies to merge with the ref ‘refs/heads/master’
from the remote, but no such ref was fetched.

### phases/14-libxml2.sh failed for ABI armeabi-v7a

Building with NDK r25 fails

The default NDK version of the GitHub Actions runner images has been updated to r25, which makes the CI builds fail with the following error:

CMake Error at /Users/runner/Library/Android/sdk/ndk/25.1.8937393/build/cmake/android-legacy.toolchain.cmake:168 (message): 15866 Disabling Neon is no longer supported

Build failure in libffi with NDK r26

Building with the newly released NDK 26.0.10792818 results in the following build error in libffi:

../src/tramp.c:262:22: error: call to undeclared function 'open_temp_exec_file'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  tramp_globals.fd = open_temp_exec_file ();
                     ^

This was already fixed in upstream libffi, but the fix is not yet part of a public release.

### phases/17-libxslt.sh failed for ABI armeabi-v7a

The previous toolchain build has been restored. The failed build can be found at:
/Users/jbheuschen/Library/Android/GNUstep.failed

Unfortunately, I'm unable to build the project as the libxslt-phase always fails to configure, saying it couldn't find the previously-built libxml2. The libxml2 build-phase, however, compiles and installs successfully. Hence, the libxml2 files in "Android/GNUStep/amreabi-v7a" are present, too. I have to admit, though, that I'm not very experienced with this kind of stuff - I hope I didn't miss something. Is this a known problem and can it be fixed? Thanks in advance for any help!

Missing: How to configure Android project for GNUstep use

As an iOS developer with little Android experience (which makes GNUstep especially tempting) I had no problem going from the toolchain setup instructions to the sample project. However, configuring your own new or existing Android project for GNUstep is not yet documented.

Looking at the linked android-examples I tried the following (maybe this can be used as a draft for a new section at the end of the existing README, once it works):

New project in Android Studio
a. Basic Fragment with View Model
b. Enable Kotlin
Create folder app/src/main/cpp
Add CMakeLists.txt () to cpp folder
Edit CMakeLists.txt to include your Objective-C implementation (.m) files in OBJECTIVEC_SRCS
Edit app/build.gradle. Add:

externalNativeBuild {
cmake {
cppFlags ""
}
}
ndk {
// ABIs supported by GNUstep toolchain
abiFilters "armeabi-v7a", "arm64-v8a", "x86", "x86_64"
}
Edit MainActivity class: Add

init {
System.loadLibrary(„native-lib“)
}

So far this fails at System.loadLibrary("native-lib") with following error:

How can I learn more about it?

Hi,

I would like to know more about the project.
Put simply, what’s this about and what I can do with this? Writing Android apps using Objective-C?
What would be the pros?
