Yeah, take a look at
/opt/RH72-BUILD-PKGS/gcc-3.2.3/OB2/i586-pc-linux-gnu/libiberty/config.log
, and see how the test is failing. If you could attach
the config.log and send it may way, I'll take a look
too...

Also, if you're building in a subdirectory of your
source directory (looks like you are), I'd suggest you
not. It's not expected to work.

Re: gcc323 + specific glibc

Hello,

one slightly hackish approach is to lie to gcc, and
make it think that it is cross-compiling. 3.2.3
doesn't support sysroot, so it's not surprising that
should fail.

Probably if you do --target=i386-redhat-linux (or some
such), configure will be stupid enough to think it's
cross-compiling, and you can use --with-headers= and
--with-libs= as you tried previously (this worked for
me a while back, when targeting libc1). Note that
you'll need to edit the libc.so from the old libc
image (it's a text file, but the paths in it will
probably be wrong) to get a fully functional 'cross'
compiler.

Cheers,

Dara

gcc323 + specific glibc

[Chris Croswhite]

Because my systems have moved to a newer glibc and my executable needs
an older glibc, I need to get gcc323 to search a specific path for
headers and libs.  During configuration I am using this:
../configure --enable-languages=c,c++ --disable-multilibs --disable-nls
--sysroot=/opt/RH72-BUILD-PKGS/GLIBC-2.2.4-IMAGE
--prefix=/opt/RH72-BUILD-PKGS/gcc323

This compiles fine, however, "print-search-path" includes /lib and
/usr/lib which is not what I want.

I have tried using the --with-headers= and --with-libs=, however, the
make file complains "*** --with-headers is only supported when cross
compiling".

What am I missing?

TIA,
Chris
