When I tried building on gcc211 a long time ago, I had so many problems with the stuff in /opt/csw that I completely ignored it. I can't help but feel that many issues with that system are admin-made and unnecessary. > Do I need to use CC='gcc -L/export/home/jakub/gcc-11-inst/lib > -R/export/home/jakub/gcc-11-inst/lib/' CXX='g++ > -L/export/home/jakub/gcc-11-inst/lib -R/export/home/jakub/gcc-11-inst/lib/' as > workaround? Instead, I've build my own copies of gmp/mpfr/mpc in ~ro/gcc with ABI=32 --disable-shared to avoid RPATH issues. I had no need for special -L/-R switches this way. The 2020 build tree is still in ~ro/gcc/obj/master.
