Hello,
I'm trying to build cloog-ppl-0.15.7, on a system with kernel 2.6.29.4,
gcc 4.1.2 and glibc 2.5.1. Actually a lfs 6.3 release.
Now the new clfs system is mounted at /mnt/sdb/3, a reiserfs system.
I get the following messages when configuring:
./configure --prefix=/tools --build=${CLFS_HOST} --host=${CLFS_TARGET}

I've seen a simular discussion at
http://lists.cross-lfs.org/htdig.cgi/clfs-support-cross-lfs.org/2009-August/000736.html
but there was no sollution there. Is there one??

It is because configure sets LD_LIBRARY_PATH to
/tools/lib:$LD_LIBRARY_PATH, right after evaluating the --with-ppl
switch. That means the next thing configure does (a cat command, which
uses libc) will be linked to the newly build cross-eglibc. Result: lots
of things go wrong.
You can try this to comment out the setting of LD_LIBRARY_PATH:
sed -i 's/LD_LIBRARY_PATH=/#&/g' configure
Setting the LD_LIBRARY_PATH isn't needed anyway, all the toolchain magic
takes care of correct linking.
Bye,
Erik-Jan
