Definitely GCC 10 isn't supported for this. Oddly enough even though you install gcc12 it's gcc10 that's being used. When I execute the offending compiler command in the chroot and using /usr/bin/g++12 instead of /usr/bin/g++10 the failure goes away. So something is wrong with your setup of the compilers. I see [ 29s] + export CXX=g++-12 [ 29s] + CXX=g++-12 [ 29s] + cmake -DCMAKE_BUILD_TYPE:STRING=RelWithDebInfo -DCMAKE_INSTALL_PREFIX:STRING=/usr -DCMAKE_MESSAGE_LOG_LEVEL:STRING=STATUS -S . -B build -GNinja -DCMAKE_C_COMPILER:STRING=gcc-10 -DCMAKE_CXX_COMPILER:STRING=g++-10 ^^^ and build/CMakeCache.txt:CMAKE_CXX_COMPILER:STRING=/usr/bin/g++-10 build/DartConfiguration.tcl:BuildName: Linux-g++-10 build/DartConfiguration.tcl:Compiler: /usr/bin/g++-10 no idea where that's injected from. GCC 10 isn't going to be fixed. -- You are receiving this mail because: You are on the CC list for the bug.
