Re: GLIBC: Problems compiling 2.1.2 on i386-linux and powerpc-linux

[Brendan John Simon <brendan at dgs dot monash dot edu dot au>]

I've just recompiled glibc-2.1.1 and glibc-2.1.2 successfully using egcs-1.1.2.  Both glibc-2.1.1 and glibc-2.1.2 fail with the same error when I try to compile them with gcc-2.95.2.  The only thing I can think of is that gcc-2.95.2 optimizes out the __libc_global_ctors function when linking.  I can see that it is there in elf/soinit.os when I use nm and/or objdump.
Maybe it is a bug in gcc-2.95.2 but I doubt it.  I'm pretty sure others have compiled (and cross-compiled) glibc-2.1.2 with gcc-2.95.2.

Any help would be greatly appreciated.
Brendan Simon.
