Guys, I've recently compiled the cilkplus branch of gcc. After a really long debugging period (2 days!) I've finally made it compile, very painfully. However, now I try to isse "suso make install" and I get: /home/leo/system/sources/gcc-cilk-obj/./gcc/cc1: error while loading shared libraries: libisl.so.10: cannot open shared object file: No such file or directory make[5]: *** [install-exec-hook] Error 1 make[5]: Leaving directory `/home/leo/system/sources/gcc-cilk-obj/i686-pc-linux-gnu/libjava' make[4]: *** [install-exec-am] Error 2 make[4]: Leaving directory `/home/leo/system/sources/gcc-cilk-obj/i686-pc-linux-gnu/libjava' make[3]: *** [install-am] Error 2 make[3]: Leaving directory `/home/leo/system/sources/gcc-cilk-obj/i686-pc-linux-gnu/libjava' make[2]: *** [install-recursive] Error 1 make[2]: Leaving directory `/home/leo/system/sources/gcc-cilk-obj/i686-pc-linux-gnu/libjava' make[1]: *** [install-target-libjava] Error 2 make[1]: Leaving directory `/home/leo/system/sources/gcc-cilk-obj' make: *** [install] Error 2 I've compiled everything from source, including gmp, mpc, mpfr, and cloog using the newer isl. No problem during compilation (no errors) using the following ./configure: ../gcc-cilk-src-svn/configure --prefix=/opt/gcc-cilk \ --disable-multilib --with-gmp=/opt/gmp --with-mpfr=/opt/mpfr \ --with-mpc=/opt/mpc --with-isl=/opt/isl --with-cloog=/opt/cloog \ --enable-language=c I've also set LD_LIBRARY_PATH accordingly. My uname -a is Linux anne 3.2.0-35-generic #55-Ubuntu SMP Wed Dec 5 17:45:18 UTC 2012 i686 i686 i386 GNU/Linux Pleas let me know if there is anymore information I can provide that can help you with this. -- Leo Ferres, Ph.D. Assistant Professor Department of Computer Science University of Concepción, Concepción, Chile
