Description Alexandra Hájková 2021-10-11 20:24:37 UTC 
gcc-11.2.1-1.fc35.ppc64le
gdb-10.2-6.fc35.ppc64le
Fedora-Rawhide

clone gdb and build it as follows

1.flags="-g3 -Og -flto" CFLAGS="$flags" CXXFLAGS="$flags" ../binutils-gdb/configure --disable-binutils --disable-elfcpp --disable-gas --disable-gold --disable-gprof --disable-ld  --enable-unit-tests --with-system-readline --with-separate-debug-dir=/usr --disable-sim
2.make -j `nproc`

results:
../../binutils-gdb/gdbserver/../gdb/arch/ppc-linux-tdesc.h:44:28: error: ‘tdesc_powerpc_isa207_htm_vsx64l’ violates the C++ One Definition Rule [-Werror=odr]
   44 | extern struct target_desc *tdesc_powerpc_isa207_htm_vsx64l;


Note:
struct target_desc is actually defined in gdb/target-descriptions.c. Not in a header.
