[Botan-devel] GCC 3.3 + Botan

[Jack L. <ll...@ac...>]

I just GCC 3.3, and ran into a few problems. For one, it looks like GCC 3.3 has
reverted back to the 2.95.3 behavior of rejecting long long constants outright,
and giving a most annoying warning even if -fpermissive -Wno-long-long is
used. To work around this, pass --gcc295x to configure.pl (I'm considering
renaming this option to --my-gcc-is-stupid or something).

More seriously, there seems to be a strange binutils bug that affects GCC
3.3 but not any previous versions, that causes big_base.cpp to be
miscompiled when -O3 -fPIC is passed to the compiler. If you're using GCC
3.3 and the check application dies with a segmentation fault, recompile
build/lib/big_base.o with LIB_OPT set to -O2. The full analysis from the
GCC folks is not in yet, but it seems this affects only older binutils.

All in all, I would say stick with earlier versions of GCC 3.x until these
problems are sorted out.
