Build log

G++ 4.7.0 (trunk from 20111219) compiler doesn't work on Solaris (x86_64-pc-solaris2.11).

But G++ 4.6.2 does.

Steps to reproduce:

# /usr/gcc/4.7/bin/g++ test.cpp -o test # FAIL
# /usr/gcc/4.6/bin/g++ -m64  test.cpp -o test # WIN

Build log is attached. Trivial test program and preprocessed files are below.

Sorry, GCC 4.7 is installed in /usr, not in /usr/gcc/4.7
Comment 6 Andrew Pinski 2011-12-23 23:53:05 UTC 
This looks like a bug in Solaris's headers.

Comment 8 Marc Glisse 2011-12-24 09:40:54 UTC 
This is supposed to be handled by fixinclude in the solaris_cxx_linkage rule. Can you try and see why it isn't applied?

Well, I'm a little confused.

Directory /usr/lib/gcc/x86_64-pc-solaris2.11/4.7/include-fixed was mostly empty.
I run /usr/lib/gcc/x86_64-pc-solaris2.11/4.7/install-tools/mkheaders, and now that directory is full on fixed headers.

Now g++ does work.


BTW GCC 4.6.2 in Solaris ships all possible fixed headers :-\
