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

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.

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
