Please, update http://gcc.gnu.org/gcc-3.2/buildstat.html.

If you answer this email, please, send me a copy since I can't cope with the volume of this mailing list.

This is a horror history. Please, read carefully. I've spend three weeks with this. I will make a long story short:

Initial State: gcc 2.95.3, binutils 2.11.2.

  1. I upgrade "binutils" to last version, 2.13. Caution here. See later.

  2. GCC 3.2 configuration: 
    # gcc -v
Reading specs from
/usr/local/lib/gcc-lib/sparc-sun-solaris2.5.1/3.2/specs
Configured with: ../gcc-3.2/configure --with-gnu-as
--with-as=/usr/local/bin/as --with-gnu-ld --with-ld=/usr/local/bin/ld
--disable-nls --enable-languages=c,c++ --disable-libgcj --disable-shared
Thread model: posix
gcc version 3.2

  3. "make bootstrap".

  4. The comparison between "stage2" and "stage3" fails miserably. The "*.o" are differents but an "objdump -D" shows that "stage2" and "stage3" object files are "equivalent". That is, the "*.o" files are not equal, but disassembly are the very same.

  5. I patch "gcc/Makefile" to skip comparison between "stage2" and "stage3" binaries, since they are not equal but seems to be "equivalent". I don't know/understand the reason.

  6. "make install".

And now all is running fine... until I try to compile a shared lib. The compilation and linking goes fine, but when anybody tries to use the shared lib, the program core dumps.

I finally determine that GNU binutils "ld" is the problem. I was using binutils 2.13. I compile binutils 2.12.1, install ONLY the "ld" component (I keep the other 2.13 utils and libraries) and every goes fine now.
