Discussion Building OpenOrbiter under Linux

[JDat]

16.11.2 works for me without issues for me, I've even managed to start compiling Orbiter under Linux (failing now, obviously)

Wow! Tell me more about compiling under linux. I am using linux daily and are really interesting into compiling under linux. How and what you are doing to compile under linux? Some tricks with <windows.h> and wine library?

Interresting. I also would like to compile Orbiter under Linux. Nevertheless, we don't have a native graphic client available for Orbiter 2016 on Linux. I know there is OGLA client which uses OpenGL but it has not been updated for using with last Orbiter version.

I don't have anything advanced just yet - just the fact of compilation itself.

Yes, I've tried wineg++ and regular gcc. wineg++ is more promising but has a number of changes to be made for "Windows" and std headers to be compatible with each other


If you want to try it as well - attached is a CMakeSettings.json which allows to compile under Linux from VS. Prerquisites:

• SSH connection set up in Visual Studio
• wine-devel and gcc on the Linux host

I like people that like challenges

 

[Linguofreak]

Has anybody tried compiling Orbiter with winelib?

Has anybody tried compiling Orbiter with winelib?

winegcc/wineg++ does exactly that if I'm not mistaken?

Is there any recipe how to compile Open Orbiter under linux without Visual Studio?
For example:

user@computer:~$ cd orbiter/build
user@computer:~$ cmake ..
user@computer:~$ make
user@computer:~$ sudo make install

or something similar.

Checkout this branch: https://github.com/DarkWanderer/orbiter/tree/linux

Then:

mkdir -p out/build
cd out/build
cmake -G Ninja ../.. -DCMAKE_CXX_COMPILER=/usr/bin/wineg++
cmake --build . -- -k0

There's a ton of errors at the moment, of course, due to

• non-POSIX functions being used in some places - e.g. _fseeki64, stricmp, _mkdir etc.
• MFC headers used
• CMakeLists still trying to make .chm files even though "MAKE_DOCS" flag is off

but the ball is rolling. Contributions are welcome

Good work getting that far with building on Linux!

Is there any reason we couldn't use the STL's std::filesystem and cstring libraries instead of relying on the Windows specific functions? We would have to compile with -std=c++17 to get std::filesystem, but I think it would be a good improvement.
