I'm on Arch Linux x86_64, attempting to build the WebRTC libraries. I get compile errors when I do:

ninja: build stopped: subcommand failed.
There appears to be a problem with link time optimization. However, I cannot figure out how to build WebRTC without LTO enabled. If I manually run the command that failed and append -fno-lto, it links fine. How can I add or change the compiler/linker flags within the gyp configuration so that it gets applied to everything?
ninja does not respect environment variables, but gyp does.
So after setting the LDFAGS environment variables, you have to run gyp_chromium to let the gyp generate correct ninja build file.
export LDFLAGS='-fno-lto'
build/gyp_chromium
ninja -C out/Release peerconnection_server
You might try to set compiler/linker flags in environment variables before build:
export CFLAGS="${CFLAGS} -fno-lto"
export CXXFLAGS="${CXXFLAGS} -fno-lto"
export LDFLAGS="${LDFLAGS} -fno-lto"
ninja -C out/Release

I'm trying to run the ./script/setup, but get compile errors:
Please note that the total 65 steps listed below is because I've restarted the setup script. The initial number of steps were closer to 465.

In order to use dealii, I tried to install p4est using the command
./configure && make && make install
and
cmake .. -DP4EST_DIR=/usr/local -DDEAL_II_WITH_P4EST=ON -DDEAL_II_WITH_MPI=ON -DCMAKE_INSTALL_PREFIX=/usr/local
under "build" folder, but some error occurs.
I also opened the file dealii-9.0.0/build/CMakeFiles/CMakeError.log, it says:

In one of my projects I'm using git submodules to download the SDL2 Library and compile it. This is giving me a strange error so I tried to compile SDL2 Standalone and I got the same error.
I'm on a 13" MacBook Pro Big Sur
Steps to reproduce:
git clone https://github.com/libsdl-org/SDL.git
cd SDL
cmake . -Bbuild
make -C ./build
The error I get is

The message would imply that Apple's own SDK files don't compile, but that can't be right. What's even stranger is that I'm using git submodules with SDL2 in another project but that compiles successfully and I can't find any discernible difference between this and the other project.
Edit:
I user make -C ./build VERBOSE=1 to compare the output with the project that successfully compiled and the project that failed to compile.

The only difference between the successfully compiled project and the project that failed to compile is the MacOS SDK version. The one that failed to compile used MacOS SDK 12 while the successful one used MacOS 11.3. Until this is fixed a temporary solution is to downgrade your MacOS SDK to 11.3.
I run some command before the actual build
add_custom_target("${PROJECT_BUILD_NUM_FILE}"
COMMAND ${PROJECT_BUILD_NUM_UPDATE} "-p" "-x" -f ${PROJECT_SOURCE_DIR}/${MAIN_PATH}/${BOARD_NAME}/${PROJECT_BUILD_NUM_FILE}
)
add_dependencies(${EXECUTABLE_NAME} "${PROJECT_BUILD_NUM_FILE}" )

Build succeeded.
It looks like ninja is checking dependencies before the actual build starts and ignores meanwhile file changed. Is there any way to force cmake/ninja to recheck dependecies after custom target is build (ie prgram that thenges the build is run).

Hey! Yes. Because DEPFILEs from C source files are generated at the same time as they are compiled, cmake has no way to know beforehand which file depends on which. It would have to do two passes - first to get dependencies and then to compile (which would be a nice feature, but actually hard to implement). It happens in one pass during compilation (-MD -MT flags), so cmake has no way of knowing that one file depends on that header. I also advise:
Do not modify files in your source tree. Keep all changes in BINARY_DIR.
Do not modify files. Generate new files. It's easier and generally, less state = less problems.
Try it such:
# Inside binary_dir
set(PROJECT_BUILD_NUM_FILE ${CMAKE_CURRENT_BINARY_DIR}/gen/buildid_gen.h)
# Add #include <buildid_gen.h> to your buildid.h
add_custom_command(
OUTPUT ${PROJECT_BUILD_NUM_FILE}
COMMAND ${PROJECT_BUILD_NUM_UPDATE} "-p" "-x" -f ${PROJECT_BUILD_NUM_FILE}
DEPENDS ${PROJECT_BUILD_NUM_UPDATE}
)
add_custom_target(buildid_gen
COMMENT "Yooohooo!"
DEPENDS ${PROJECT_BUILD_NUM_FILE}
)
add_executable(${EXECUTABLE_NAME} ${PROJECT_BUILD_NUM_FILE} ${some_other_sources})
target_add_include_directories(${EXECTABLE_NAME} PUBLIC
# add include directory, so that buildid_gen is found
${CMAKE_CURRENT_BINARY_DIR}/gen
)
# this *helps*
add_dependencies(${EXECUTABLE_NAME} buildid_gen)
Is there any way to force cmake/ninja to recheck dependecies after custom target is build (ie prgram that thenges the build is run).
The real proper way ™ would be to manually track all files that depend on the file (you could think of grep -l '#include <buildid_gen.h> to get the list files) and communicate to cmake the dependency relation:
add_source_file_properties(${sources_that_include_buildid_gen} PROPERTIES OBJECT_DEPENDS ${PROJECT_BUILD_NUM_FILE})
Tracking dependencies is easier if you use a runtime interface (ie. long get_build_id();) cause then only one .c file that implements the interface will depend on the generated file.
There are also some projects that are compiled in two passes because of such dependencies, you have to first cmake .. --target buildid_gen and then cmake .. --target actually_compile each time you compile.
Also maybe execute_process is more appropriate if the file is setup once per build.
I'm building a shared library and an application using that lib on Cygwin. With GCC CMake creates a .dll.a to use when linking. Switching to clang I get
[ 34%] Built target xxx_shared
make[2]: *** No rule to make target 'src/libxxx.dll.a', needed by 'xxx.exe'. Stop.
Is this a bug in the clang CMake extension?
I'm using cmake --version 3.3.2
Yes, it seems to be a bug in CMake. Running make VERBOSE=1 reveals that with GCC:
/usr/bin/c++.exe -g -shared -Wl,--enable-auto-import -o XXX -Wl,-Bstatic -lm -Wl,-Bdynamic -lstdc++ -lcygwin -ladvapi32 -lshell32 -luser32 -lkernel32
while with clang:
/usr/bin/clang++ -fPIC -g -shared -o XXX -Wl,-Bstatic -lm -Wl,-Bdynamic -lstdc++ -lcygwin -ladvapi32 -lshell32 -luser32 -lkernel32
So it seems that somehow clang++ does not get the -Wl,--enable-auto-import flag. Manually running the corrected clang++ command correctly creates the expected .dll.a allowing the rest of the build to proceed as expected.
Haven't figured out why this happens yet, though. At this point I can't decipher CMakes platform extensions, which seems to set this for GCC.
Update: I've reported this here.
