I made my first attempt to build on an x86_64-unknown-linux-gnu system.
Is this supposed to work? I get libtools errors (below). The problem seems
to be that it finds a 32-bit libltdl rather than the 64-bit libltdl.
/home/dag> ls /usr/lib/libltdl.so.3.1.0
/usr/lib/libltdl.so.3.1.0
/home/dag> ls /usr/lib64/libltdl.so.3.1.0
/usr/lib64/libltdl.so.3.1.0
Is this a known problem? I'm not very familiar with how libtools works so
I'm
a bit hesitant to hack up ltmain.sh.

On my gentoo/amd64 installation i could get llvm and llvm-gcc to compile. llvm/tests are mostly passed the test-suite fails with a glibc double free error. you could try setting the CC="gcc -L/usr/lib64" or maybe even CC="gcc -m64 -L/usr/lib64" environment variable and likewise for CXX before configuring and make. although i would guess that something is wrong with your install because it should find the 64bit libs by default (that is if your on a 64bit system) but i am not a linux expert so take everything i say with a grain (boulder) of salt gritz arnold On 9/20/07, David Greene <dag at cray.com> wrote:> I made my first attempt to build on an x86_64-unknown-linux-gnu system. > Is this supposed to work?

I just ran into a similar problem building another package that uses libtool. The only "non-standard" flag I passed to configure when building gcc was --disable-shared, but I don't see how that would affect the search path for libraries. libtool does it's own searching and I don't think it cares where gcc looks. But again, I know very little about libtool, mostly just from looking at sh -x output. Does anyone have any insight as to how libtool finds libraries? Why can't it just pass -lltdl to the linker like the compile command told it to? -Dave
