v6.0.0-alpha-96 how to compile?

[leukimi]

It seems difficult to compile v6.0.0-alpha-96 on any linux platform following the guide. Linphone SDK which this version pulls is v5.4.0-alpha-399.

cmake on Fedora 40 cannot find some submodules such as decaf, jpeg, turbo-jpeg in its own file structure and bcunit seems to be missing. cmake also complains about several modules not having a CMakeFiles.txt.

However, you seem to be able to produce semi-working 6.0.0-alpha AppImages, which means that the source code should be able to compile.

Which devel-packages are you using on which version of Linux to make the source code compile?

For Fedora 40, these devel packages seems to be needed: git nasm yasm cmake meson doxygen python3-six qt6-qtbase-devel libv4l-devel glew-devel alsa-lib-devel pulseaudio-libs-devel qt6-qtdeclarative-devel qt6-qtsvg-devel qt6-qtmultimedia-devel qt6-qtnetworkauth-devel libXext-devel

python3-pystache RPM package can either be downloaded or installed with python3-pip.

On local Fedora 40 box, this can happens and is due to that git for unknown reason does not pull all submodules:

external/linphone-sdk/cmake/ExternalDependencies.cmake:418 (add_subdirectory):
The source directory external/linphone-sdk/external/decaf does not contain a CMakeLists.txt file.

external/linphone-sdk/cmake/ExternalDependencies.cmake:687 (add_subdirectory):
The source directory external/linphone-sdk/external/libjpeg-turbo does not contain a CMakeLists.txt file

external/linphone-sdk/cmake/ExternalDependencies.cmake:1311 (add_subdirectory):
The source directory external/linphone-sdk/external/openldap does not contain a CMakeLists.txt file.

external/linphone-sdk/cmake/ExternalDependencies.cmake:1331 (add_subdirectory):
The source directory external/linphone-sdk/external/opus does not contain a CMakeLists.txt file.

external/linphone-sdk/cmake/BCProjects.cmake:27 (add_subdirectory):
The source directory external/linphone-sdk/bcunit does not contain a CMakeLists.txt file.

external/linphone-sdk/bctoolbox/cmake/FindBCUnit.cmake:77 (find_package):
Could not find a package configuration file provided by "BCUnit" (requested version 3.0.2) with any of the following names:
BCUnitConfig.cmake
bcunit-config.cmake
Add the installation prefix of "BCUnit" to CMAKE_PREFIX_PATH or set "BCUnit_DIR" to a directory containing one of the above files.

Remedy is to delete the problematic directories and pull again with git.

Which linux platform is best suited to compile version v6.0.0-alpha on?

Which cmake variables do you set manually?
-DENABLE_TESTS=OFF
-DCMAKE_TOOLCHAIN_FILE=/usr/lib64/cmake/Qt6/qt.toolchain.cmake

I also tried to use version 6, but the result was the same as yours, compilation also came up with ERROR and took more time than it should have and could not be resolved.

So I chose to fall back to tag 5.2.6.

I will continue to wait and see~
