[Linux-ia64] Problem compiling latest gcc (001024 snapshot)

[Francis Galiegue]

I tried to get the latest snapshot of gcc on cygnus to compile... but it fails
with this error:

/usr/src/RPM/BUILD/src/builddir/gcc/xgcc -B/usr/src/RPM/BUILD/src/builddir/gcc/

Machine is a BigSur, A0 stepping CPU. Glibc is 2.1.3 (and 2.1.3 patch is
applied), gcc is 2.9-ia64-000216-final. Kernel is 2.4.0-test7 with ia64 patch.
I also tried to compile with RCS patches present in the snap directory, up to
031, but to no avail, still the same error. READMEs in the sources don't help.

I'm stuck... Do you see what I did wrong? Would the .032 and .033 patches help?

Oh, and BTW, .033 is unreadable, it's 600 on the FTP site.

Build new gas first, install it and try again.

Somehow gcc accidentally used an out-of-date assembler.

>/usr/src/RPM/BUILD/src/builddir/gcc/xgcc -B/usr/src/RPM/BUILD/src/builddir/gcc/
>-B/usr/ia64-mandrake-linux/bin/ -I/usr/ia64-mandrake-linux/include -O2

The -B options here are in the wrong order.  If you have an old assembler in
/usr/ia64-mandrake-linux/bin/, then gcc will accidentally use this old
assembler instead of the new assembler in /usr/src/.../builddir/gcc.
This can be fixed by doing a "make install-gas" as Jes suggested, or by
renaming the old /usr/ia64-mandrake-linux tree to move it out of the way as
Bill suggested.

We've had a lot of problems with ordering of these -B options.  It has been
broken and fixed several times this year.  The current stable compiler I am
maintaining was made from a FSF gcc snapshot when this was broken.  This
is only a problem when there is an ABI change though, so hopefully you only
have to deal with this once.

Fixed.
