Hi,
ports prrovide two gcc's 4.9 and 8.
I have a program which compiles fine with up to gcc 7, also the system
clang is too "new". On OpenBSD 6.4 I could use the system clang.
Now, a solution would be to install gcc 6.5 or 7.4, a compiler which I
know works fine on NetBSD and Linux for ArcticFox.
I want to make it as stock as possible, I did not apply any patches. I
took inspiration from:
https://raw.githubusercontent.com/openbsd/ports/master/lang/gcc/8/Makefile
I installed gmake, gas, bison, libexecinfo
I ended up with this command line (the rationale is not to overwrite
anything of ports, put it :
./configure --prefix=/usr/local/gcc7 --program-suffix=7
--enable-languages=c,c++,objc,obj-c++ --enable-shared --enable-wchar_t
--enable-threads=posix --disable-nls --with-system-zlib
--disable-libmudflap --disable-libgomp --disable-libssp --with-gnu-ld
--with-gnu-as --with-gmp=/usr/local --disable-libstdcxx-pch
--without-isl --enable-cpp --with-arch=sandybridge
--with-tune=sandybridge --enable-default-pie CC=clang CXX=clang++ AS=gas
however compilation fails:

Anyone has a useful suggestion to get gcc7 ?
Thanks,
