Well, it didn't take long to hit a problem on CentOS 6. Apparently
GCC 4.4.7 cannot compile the current gcc5.
That's really unfortunate. If we can't patch it, I wonder if that
means people on older systems should do some multistage bootstrap from a
script before running pkgsrc proper.
Or maybe they should build and use clang.
Hold the phone...
Most of the GCC issues I'm hitting seem to be caused by FORTIFY_SOURCE.
I see that the current Joyent packages for CentOS 7 are missing 4.9, 5,
and 6. Only 4.8 and 7 are present. I hit the same failures in my bulk
builds, but so far PKGSRC_USE_FORTIFY=no fixed 4.9 and 5. My gcc6 build
is running now. All these are using 4.8 as the base compiler. I'll
attempt another gcc5 build using the 4.4 base compiler +
PKGSRC_USE_FORTIFY=no shortly and will report more tomorrow after
sorting all this out.
