freeorion-sdk's Introduction

FreeOrion

FreeOrion is a free, Open Source, turn-based space empire and galactic conquest computer game.

FreeOrion is inspired by the tradition of the Master of Orion games, but does not try to be a clone or remake of that series or any other game. It builds on the classic 4X (eXplore, eXpand, eXploit and eXterminate) model.

By adding scripting capabilities to the game engine the FreeOrion project aims to give the community an easy way to customize the game mechanics and presentation to create a living, breathing universe in a grand campaign model.

Requirements

FreeOrion requires an OpenGL 2.1 capable graphic card and a display with a suggested minimum resolution of at least 1280x800.

Recent releases of FreeOrion require at least Windows 8.1 or later, macOS 10.12 or later or any reasonably recent Linux distribution on x86 compatible processors, such as Ubuntu 20.04 or 22.10. Other operating systems and architectures have reported to be working by users, but are not actively supported by the FreeOrion project.

Download

FreeOrion Stable Releases are the recommended way to play FreeOrion. Stable Releases can be obtained as native installer binaries for Windows and Mac OSX or as source releases for Linux and other UNIX-ish platforms from GitHub.

Some Linux distributions like Fedora, Debian and Arch provide packages of FreeOrion. Alternatively, FreeOrion is also available on Flathub.

FreeOrion Weekly Releases are in-development releases intended for enthusiasts and testers, who want to track or contribute to the development. Weekly Releases can be obtained as native installer binaries for Windows and Mac OSX from Sourceforge.

Install

For Windows, execute the native installer binary and follow the on-screen instructions of the installer to install FreeOrion.

For Mac OSX, open the downloaded DMG file and copy the contained FreeOrion application to your system Applications folder by Drag and Drop.

For Linux or other from-source installations, refer to the Build Instructions.

Various Linux distributions provide the stable release of FreeOrion in a prebuilt way. Usually you can install those packages by either using a graphical package manager and searching for FreeOrion or by installing the packages via the command line.

Debian package stable release: # apt-get install freeorion
Ubuntu package stable release: # apt-get install freeorion
Fedora package stable release: # dnf install freeorion
Gentoo package stable release: # emerge games-strategy/freeorion
Void package stable release: # xbps-install freeorion
ArchLinux package stable release: # pacman -S freeorion
openSUSE package stable release: # zypper in freeorion

To install FreeOrion from Flathub, follow the instructions to install Flatpak and Flathub and then install FreeOrion.

freeorion-sdk's Issues

Boost_PYTHON_LIBRARY symbol not correctly set

When trying to build FO with a SDK based on latest master (2758d37), the build fails during the post build phase where the application bundle gets generated:

make: *** [freeorion_buildpart_0] Error 1
Command /bin/sh failed with exit code 2

As far as I could narrow it down, the problem is that the Boost_PYTHON_LIBRARY symbol doesn't get set correctly, resolving to an empty string, causing the cmake -E copy_if_different command that is supposed to copy the Python framework into the app bundle to fail.

Max OSX - Boost fails to find SDKs

OSX: 10.12.5 XCode: 8
Build fails during boost build:

/opt/projects/freeorion-sdk/build-cm/boost-prefix/src/boost/tools/build/src/build/feature.jam:494: in validate-value-string from module feature

build_log.txt

Resolved by adding symlink, as noted in workaround for https://svn.boost.org/trac/boost/ticket/10275.

PDB file not found

When linking FreeOrion, I get a bunch of missing pdf file warnings:

1>freetype255MT.lib(autofit.obj) : warning LNK4099: PDB 'freetype.pdb' was not found with 'freetype255MT.lib(autofit.obj)' or at 'C:\Users\Geoff\Desktop\FreeOrionSDK3\FreeOrion\freetype.pdb'; linking object as if no debug info

Might be nice to put it where expected / include in the SDK.

compiling takes A LONG TIME

Takes about 5 minutes to build freeorion on liquid-cooled AMD FX-9590 8 x 5.2GHz, with every core is loaded 100%. This seems to be too long for such a small game (even boost is built much faster, while libpng is built in 2 seconds). Not sure if problem of MSVS itself, but mingw builds are typically much faster (maybe 10 times faster) without any drawbacks, so maybe you could consider replacing MSVC for mingw on windows. With such frequent updates compilation is painful.

[mac-support branch] patch step for target python-cmake fails

Application of the patch fails with the following error message:

[ 56%] Performing patch step for 'python-cmake'

Open tasks for SDK

This issue contains things to check before declaring the setup working:

Travis-CI doesn't contain any artifact deployment as Github Release.
Validate MacOSX SDK file layout.
Validate MacOSX SDK ABI compability.
Check if MacOSX build flags are matching the regular upstream build flags for all dependencies.
Validate Windows SDK ABI compability.
Check if Windows build flags are matching the regular upstream build flags for all dependencies.
Write initial ChangeLog.md.

Can't Link GLEW when building FreeOrion (GiGiSDL) with Windows x64 SDK

When trying to build FreeOrion in x64 configuration against the x64 SDK, I get a bunch of GLEW link errors. After I downloaded the GLEW binaries and replaced the .lib in the SDK with the x64 .lib from the download, the linker errors went away.

Bump Boost Version

When buliding FreeOrion in MSVC with the Boost version currently in the SDK, there are a bunch of warnings like
**include\boost\function_output_iterator.hpp(14): message : This header is deprecated. Use <boost/iterator/function_output_iterator.hpp> instead.** throughout the build log. These seem to come from within Boost code, not anything FreeOrion or the SDK are doing.

I assume that bumping the Boost version a bit would resolve this.

Add python3 to Windows and MacOS SDKs

To follow up #46 and to move forward in python 3 migration (https://freeorion.org/forum/viewtopic.php?f=9&t=11181) there should be support for python 3 in Windows and MacOS SDKs as well.

Symbol visibility for Boost libraries

Since the FreeOrion code is being compiled with -fvisibility=hidden for Clang:
freeorion/freeorion@d77858f

... shouldn't that also be done for the SDK?
I did a search through the CMakeLists.txt file, and didn't get a hit.
Travis builds are getting a lot of warning messages (for the regular FO build) due to the current Boost libraries and the visibility setting mismatch.

[mac-support branch] libvorbis install fails

cmake .runs successfully, but the subsequent cmake --build . --config RelWithDebInfo fails with the following error message when trying to build target libvorbis:

Windows build documentation

@geoffthemedio

In #8 we tried to convince CMake to build the SDK with various generators and toolsets. Could you please check if the configuration still works without those additional parameters (-T, -G) and we still get the desired SDK for the desired VisualStudio+toolset or if the README.md needs to be updated?

Mac OSX SDK: wrong library id names and paths in mach headers of shared libraries

Stumbled upon another issue with the shared libraries the cmake scripts produce. Noticed that in the Ogg and Vorbis binaries of the Ogg and Vorbis frameworks. The library paths as returned by the otool command are as follows:

user$ otool -L Ogg
Ogg:
    Ogg.framework/Versions/1.3.2/Ogg (compatibility version 0.8.2, current version 0.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

user$ otool -L Vorbis
Vorbis:
    Vorbis.framework/Versions/1.3.5/Vorbis (compatibility version 0.0.0, current version 0.0.0)
    Ogg.framework/Versions/1.3.2/Ogg (compatibility version 0.8.2, current version 0.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

When built and linked with the libraries containing these paths in their mach headers, the FO app immediately quits when launched, with the dynamic linker giving an error that it can't find the binary images.

What the paths (and id names) need to be is:

user$ otool -L Ogg
Ogg:
    @executable_path/../Frameworks/Ogg.framework/Versions/1.3.2/Ogg (compatibility version 0.8.2, current version 0.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

user$ otool -L Vorbis
Vorbis:
    @executable_path/../Frameworks/vorbis.framework/Versions/1.3.5/Vorbis (compatibility version 0.0.0, current version 0.0.0)
    @executable_path/../Frameworks/Ogg.framework/Versions/1.3.2/Ogg (compatibility version 0.8.2, current version 0.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

Of course that applies to all the dynamic libraries generated by the cmake scripts too (Python etc.).

Boost Version in README.txt

README.txt in the SDK says

Boost 1.58          - http://www.boost.org/users/history/version_1_58_0.html

But the version of Boost the SDK downloads is 1.59

Specifying MSVC Toolset v141 Produces v140 SDK

I've installed MSVC 2017 and CMake 3.9.3. I then used the provided instructions to produce the SDK, additionally specifying that MSVC 2017 and toolset v141 should be used. This runs, and generates a .zip as expected.

However it appears to have still used the v140 (MSVC 2015) toolset. This can be seen from filenames and looking into binary dependencies; all the boost libraries and DLLs have vc140-mt-1_59 in their filenames, and matching dependencies in Dependency Walker. python27.dll and libpng16.dll depend on VCRUNTIME140.DLL in Dependency Walker.

Output from generating the SDK:

build_CMake_step_1.txt
build_CMake_step_2.txt

Windows - CMake output has -prefex on dir names

As in the attached, the output of the generate step with the CMake GUI has -prefix on the dependency directory names.

The SDK build in MSVC 2015 from the solution still starts up and finishes at least a few projects, so it might not be an practical problem.

MSVC2017 - Building boost fails

Environment

OS: Win10
Compiler: MSVC2017

Problem description:

When building the SDK as per instructions, the boost project will fail to build with MSVC2017 because it looks for clang (and fails to find which is expected). The same problem has previously been reported in the forum.

Relevant log:

CUSTOMBUILD : warning : toolset clang-linux initialization: can not find tool clang++ [D:\FOTestBuild\freeorion-sdk\build\boost.vcxproj]
CUSTOMBUILD : warning : initialized from D:\FOTestBuild\freeorion-sdk\build\boost-config.jam:20 [D:\FOTestBuild\freeorion-sdk\build\boost.vcxproj]
  '"clang++"' is not recognized as an internal or external command,
  operable program or batch file.
  notice: will use 'clang++' for clang-linux, condition <toolset>clang-linux

As a workaround, I deleted the following lines
https://github.com/freeorion/freeorion-sdk/blob/master/boost-config.jam.in#L15-L20
which allowed me to build the SDK just fine.

Steps to reproduce:

git clone https://github.com/freeorion/freeorion-sdk
cd freeorion-sdk
mkdir build && cd build
cmake ..
cmake --build . --config RelWithDebInfo

Expected result:

Do not try to use clang under windows

MSVC 2015 FreeOrion build fails

Just generated the SDK (with the MSVC 2015 compiler), unpacked it, and ran the bootstrap to get the freeorion code, then loaded the MSVC 2013 project files in MSVC 2015). I then tried to build freeorion. Most of it compiles, but I'm getting some errors, mostly in boost serialization stuff...

Not sure if you want such errors here in the SDK, but I wondering if using a newer version of boost (currently it downloads 1.59) might help...

There are also some possibly relevant warnings...

Switch Boost library version?

The FO-SDK currently uses Boost v1.59.

I noticed a recent FO PR freeorion/freeorion#1775
... where it sounds like Fedora users might want Boost v1.63 or higher to resolve certain ptr problems.

Question: Would it be beneficial to switch Boost versions (1.59 to 1.63) for everyone?
I don't know what safeguards are in place.
Or maybe this kind of action is strictly forbidden (except to select experts).

I might be interested in this switch for the Mac. There is a request (in PR #29) to have B2 handle renaming shared library path names. This was broken for 1.59, but I found a discussion thread where someone claimed it was fixed by 1.63. I'd be willing to check this, but I want to know before putting in the work if this is a viable solution or not.

(Also, I don't have a Windows system, so someone else would have to test for side effects. I wouldn't want to make life difficult for the Windows users, if switching Boost versions would cause a headache.)

Mac OSX SDK: Compile and link errors

Using the dep folder produced with bd3379c I encountered the following issues:

A compile error that ft2build.h can't be found, which can be solved by adding dep/include/freetype to the header search paths of the Xcode project.
With the previous issue fixed, I still get these link errors when trying to build the FreeOrionServer target:

Also strangesoft.net seems to be a domain parking page.

Building SDK with MSVC 2019

I installed MSVC 2019 and tried to build the SDK. I ran into issues:

GLEW 2.1.0 fails to link, as discussed here nigels-com/glew#238 (comment) and possibly fixed by this: nigels-com/glew@4bbe8aa but I don't know how to apply that when building the SDK. Editing the GLEW CMakeLists.txt after the build failed once and re-starting it doesn't restart the build.
I had to modify the build command slightly to specify the Win32 target: C:\Users\Geoff\Desktop\freeorion-sdk\build>cmake .. -G "Visual Studio 16 2019" -A Win32

v7 but label=6 in docker file

The master-branch and v7-tag both have label=6 in the docker file. Should that not have been bumped up and deployed? (I guess to 7 for v7 ??).
