Greetings fellow CLFS builders,
We are needing to update gcc.
I'm fond of updating gcc to 4.7.3 rather than 4.8.0. I mentioned
earlier that graphite had issues with 4.8.0 with throwing segfaults
everywhere. I went to 4.7.3 an didn't have issues. The author of
0linux has the same thought, and sticks with 4.7.3 as of now. I know
gcc 4.8.0 has a lot of features which people will want, and 4.7.3
isn't far behind, but it is more stable as of now, as far as I'm
concerned with graphite. CLFS includes graphite, and so it seems
important that graphite work properly. I do not know what gcc 4.8.0
has which causes graphite to be a problem. 4.7.x is fine. It could be
a problem with cloog-isl or some other graphite component.
Should we go for GCC 4.7.x or 4.8.0? I'm shooting for 4.7.x.
What we want is stability. The last thing we want is someone building
CLFS with gcc 4.8.0 then wanting to use graphite options and then
everything segfaults all over the place. Or we could use gcc 4.7.3 and
graphite options don't cause segfaults all over the place.
4.8.0,. allows us to remove ppl which takes a long time to check, we
have always been cautious with optimisation in builds as they often
cause problems whatever they are.
Have encountered no major problems with 4.8.0 and 4.8.1 will be out in a
week or so
Common problems with gcc 4.8.0 and graphite: ncurses and readline.
Those caused the most issues with my experimental builds.
Sincerely,
William Harrington
