How to build on linux? [unstable 2.0, CMake]

edited 2015 Aug 9 in Developers
Hi,

Originally I used to build this project using the following command line:

qmake-qt4 -r ../doomsday.pro PREFIX=/mnt/games/native_games/doomsday CONFIG+=deng_notools

I have not built it for a while and it appears that the doomsday.pro no longer exists?

I assume that the project has moved away from qmake so I went to the distrib folder and run the following command:

python platform_release.py

This starts configuring as expected but fails with the following problem:
CMake Error at sdk/libgui/CMakeLists.txt:17 (add_subdirectory):
  The source directory

    /mnt/games/native_games/games_source/deng-code/doomsday/external/assimp

  does not contain a CMakeLists.txt file.


CMake Error at sdk/libgui/CMakeLists.txt:18 (set_property):
  set_property could not find TARGET assimp.  Perhaps it has not yet been
  created.

Have I skipped a step? What is the correct procedure for building from source nowadays?

Thanks

    The 1.15 stable release was the last one where we used qmake. Since then, in the master branch, we've switched to CMake (3+).

    The platform_release.py script is part of our autobuilder system and probably will not do exactly what you'd like, since it produces a distribution package rather than just doing a build.

    Assimp is a Git submodule, so if you are building in a Git repository, you need to git submodule update --init. This will check out the appropriate version of the Assimp library into doomsday/external/assimp.

    We haven't updated the wiki with new build instructions yet, since the current stable version is still using the old build mechanism. However, when you have the Assimp sources checked out, it's pretty much a standard CMake build:
    1. Create a build directory outside/next to the source tree.
    2. Run CMake on doomsday/CMakeLists.txt.
    3. Check the CMake configuration options for any customization needs, particularly the *_DIR and DENG_ENABLE_* variables. You should set the installation prefix with the PREFIX variable.
    4. make && make install

    Hi skyjake.

    Many thanks for your response. The build now gets past the assimp issue but seems to have a new one.

    Cmake appears to invoke some python scripts that are expecting some zip files but in linux they appear to be directories?

    I get the same issue if I run the autobuild.py in he distrib folder.

    Should linux treat the .pack as an extension rather than a folder name?
  • skyjakeskyjake
    The .pack files work the same way on all platforms. In the repository, they are folders, however the build scripts will compress them into ZIP archives that still use the .pack extension.

    Did you create a separate build directory and run CMake from there? It should not be trying to overwrite anything the source tree.
  • toxicshadowtoxicshadow
    The build folder is outside of the main source directory. This is the command I am running:

    cmake ../deng-code/doomsday/CMakeLists.txt
  • toxicshadowtoxicshadow
    I deleted the source and got a clean copy and run the following command (part of a script):

    cmake -DCMAKE_INSTALL_PREFIX=$INST_PATH ../doomsday

    cmake now functions correctly and a Makefile is created. Now make fails @ 27% with the following errors:

    std::function errors seem to be because "--std=c++11" is missing? I am not sure but it looks like part of assimp disables this as part of its build process?
  • skyjakeskyjake
    "cotire" is a 3rd party helper macro we use to set up precompiled headers and other build streamlining. However, it sometimes seems to have issues with GCC — I should disable it by default when using GCC.

    I recommend you set DENG_ENABLE_COTIRE to NO.

    On Linux, "ccache" is very helpful if you do repeated builds. Doomsday's CMake config will autodetect if you have ccache installed and use it.

    That did the job thanks!

    Out of interest is there a way to remove the 35FPS frame rate limiter?
