gcc-3.1 build fails on Solaris-2.7 with --with_gnu_ld

[Christophe Lyon]

Hi,

I am trying to install gcc-3.1 on a Sparc/Ultra 60 under
Solaris 2.7 using the --with-gnu-ld switch at configure time.

The build process fails when configuring in 
sparc-sun-solaris2.7/sparcv9/libiberty

Configure reports:
configure: error: installation or configuration problem: C compiler
cannot create executables.

and the config.log says:
configure:2212: /tmp/pkg-build-gnumgr/gcc-3.1/gcc-3.1/gcc/xgcc
-B/tmp/pkg-build-gnumgr/gcc-3.1/gcc-3.1/gcc/

conftest.c  1>&5
/usr/lib/libdl.so.1: could not read symbols: Invalid operation


Indeed, I think it should read /usr/lib/sparcv9/libdl.so in that case.
Playing with LD_LIBRARY_PATH can solve this issue, but I don't really
want /usr/lib/sparcv9 to be first in my $LD_LIBRARY_PATH all the time!

(and if I do so, configuration of libiberty would fail earlier).

I have found similar questions over the www, but no reply :-(

Is this a know bug, or am I doing something wrong?

(I am using ld from binutils-2.11.2)

Regards,

Christophe.

That's what LD_LIBRARY_PATH_64 is for, however...

...I suspect a binutils bug.  The incompatible library should be skipped.

You could try a newer binutils, or build with Sun's as/ld, or disable
multilibs.
