From: "ohsumit at molbio dot mgh.harvard.edu" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c/51129] New: 4.7 trunk libgcc cannot compute suffix of object files - cannot find find libcloog, though in path Date: Mon, 14 Nov 2011 20:16:00 -0000 [thread overview] Message-ID: <bug-51129-4@http.gcc.gnu.org/bugzilla/> (raw) http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51129 Bug #: 51129 Summary: 4.7 trunk libgcc cannot compute suffix of object files - cannot find find libcloog, though in path Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: blocker Priority: P3 Component: c AssignedTo: unassigned@gcc.gnu.org ReportedBy: ohsumit@molbio.mgh.harvard.edu I am trying to compile the trunk version of gcc (checked out around 2:30 PM Eastern Nov. 14, 2011) under SuSE linux using gcc 4.1.2 20070115 (default installed). I have cloog-ppl-0.15.11, gmp-5.0.2, mpc-0.9, and mpfr-3.1.0 all installed in /usr/local/{include,lib} and have m4-1.4.16 in /usr/bin. All of the libraries passed their checks before I installed them. I have declare -x LDFLAGS="-L/usr/local/lib -L/usr/local/lib64 -L/usr/lib -L/usr/lib64 -L/lib -L/lib64 -R/usr/local/lib:/usr/local/lib64:/usr/lib:/usr/lib64:/lib:/lib64" declare -x LD_LIBRARY_PATH="/usr/lib:/usr/lib64:/lib:/lib64:/usr/local/lib:/usr/local/lib64 Now in the below, directories /tools and /store1/tools are identical. I then did sudo /tools/gcc-4.7.0_src/configure --enable-langugages=c,c++,fortran --prefix=/tools/gcc-4.7.0 --with-gmp-include=/usr/local/include --with-gmp-lib=/usr/local/lib --with-mpc-include=/usr/local/include --with-mpc-lib=/usr/local/lib --with-mpfr-include=/usr/local/include --with-mpfr-lib=/usr/local/lib --with-ppl-include=/usr/local/include --with-ppl-lib=/usr/local/lib --with-cloog-include=/usr/local/include --with-cloog-lib=/usr/local/lib in directory /tools/gcc-4.7.0_build followed by "sudo make -j6". (I also tried it without the -j6. Same problem.) It compiles xgcc in subdirectory gcc successfully. However, then the build crashes on mkdir -p -- x86_64-unknown-linux-gnu/libgcc Checking multilib configuration for libgcc...

Furthermore, I specified the path to cloog in the configure options. (I even tried doing a soft-link to /usr/lib, but with no success.) Any thoughts on why this is occurring? I would be grateful for any information regarding how to resolve this.
