Hi list,
I am trying to build gcc with the following command
../../gittea/gcc/configure -v
--prefix=/home/vincenzopalazzo/build-dir/gcc
--enable-languages=c,c++,rust --disable-multilib
and when I ran `make` I got the error reported below. I have the feeling
that I am missing something, because this code is not touched since
2012 (thank git blame)
so I am pretty sure that I am missing something, but not sure what.
P.S: the gcc version that I use to compile gcc is 12.3.0
cc1plus: some warnings being treated as errors
You are missing to tell what is the C++ compiler you are using to
compile the
'libcpp' stuff. Please don't expect a C++ compiler from 2012 or
earlier to
"grok" some uptodate C++ code. For the gcc-12.3.0 sources I myself would
try gcc-7.5.0 or newer as the stage-1 compiler in the native-GCC case.
Maybe I misunderstood your writing.... Using gcc-12.3.0 to compile some
old GCC sources would also be questionable. Using some older g++ then
would succeed.
