             Bug #: 50049
           Summary: bootstrap fails if libcloog in unusual spot, even with
                    --with-cloog= set
    Classification: Unclassified
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rbrt.somerville@gmail.com


i seem to have to have LD_LIBRARY_PATH set to point to libcloog library
directory ... --with-cloog= or --with-cloog-lib= is not enough . It fails when
it goes into stage 1, it cannot find libcloog to complete a link. I am under
impression i should not have to have LD_LIBRARY path set to do a bootstrap
w.r.t. libcloog

attaching:
objdir/x86_64-unknown-linux-gnu/libgcc/config.log

That is a standard non issue really as you are support to have the shared
libraries in a spot that can be found at runtime while building GCC.

then why the --with-cloog= option ?? , see documentation for building . i
quote:

"" In both cases --with-cloog configure option should be used if CLooG is not
installed in your default library search path. ""

That is for built time library search path.  If you use a shared library rather
than a static archive then you also need to set up the runtime path.

i believe that the build should use the static libcloog that exists, after all
the build has no problems with MPC,MPFR,GMP, and PPL needing an LD_LIBRARY_PATH

the build has no problems with MPC,MPFR,GMP, and PPL needing an LD_LIBRARY_PATH
, which are also in a non-standard location ( the same as libcloog )
