Fabrice Fontaine 6b33250c59 build/CMakeLists.txt: enable C language ... Detection of libatomic is broken since version 2.47.0 and b7f0d87daf because C language is not enabled anymore: -- Looking for __atomic_fetch_add_4 in atomic -- Looking for __atomic_fetch_add_4 in atomic - not found CMake Error at cmake_modules/CheckAtomic.cmake:59 (message): Host compiler appears to require libatomic, but cannot find it. Call Stack (most recent call first): CMakeLists.txt:54 (include) Indeed if C language is not enabled, the test will be run with the C++ compiler resulting in the following error: Building CXX object CMakeFiles/cmTC_03d01.dir/CheckFunctionExists.cxx.o /home/fabrice/buildroot/output/host/bin/x86_64-linux-g++ --sysroot=/home/fabrice/buildroot/output/host/x86_64-buildroot-linux-gnu/sysroot -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -O1 -g0 -D_FORTIFY_SOURCE=2 -DCHECK_FUNCTION_EXISTS=__atomic_fetch_add_4 -DNDEBUG -o CMakeFiles/cmTC_03d01.dir/CheckFunctionExists.cxx.o -c /home/fabrice/buildroot/output/build/i2pd-2.49.0/build/CMakeFiles/CMakeScratch/TryCompile-NApnv9/CheckFunctionExists.cxx <command-line>: error: new declaration ‘char __atomic_fetch_add_4()’ ambiguates built-in declaration ‘unsigned int __atomic_fetch_add_4(volatile void*, unsigned int, int)’ [-fpermissive] whereas with a C compiler, we'll get: Building C object CMakeFiles/cmTC_7e47b.dir/CheckFunctionExists.c.o /home/fabrice/buildroot/output/host/bin/x86_64-linux-gcc --sysroot=/home/fabrice/buildroot/output/host/x86_64-buildroot-linux-gnu/sysroot -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -O1 -g0 -D_FORTIFY_SOURCE=2 -DCHECK_FUNCTION_EXISTS=__atomic_fetch_add_4 -DNDEBUG -o CMakeFiles/cmTC_7e47b.dir/CheckFunctionExists.c.o -c /home/fabrice/buildroot/output/build/i2pd-2.49.0/build/CMakeFiles/CMakeScratch/TryCompile-e0zFMG/CheckFunctionExists.c <command-line>: warning: conflicting types for built-in function ‘__atomic_fetch_add_4’; expected ‘unsigned int(volatile void *, unsigned int, int)’ [-Wbuiltin-declaration-mismatch] Fix #1908 Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com>		2023-11-12 10:29:24 +00:00
