Bug #: 53126 Summary: gcc-4.7.0 error "gcc-ar: Cannot find plugin" Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: critical Priority: P3 Component: plugins AssignedTo: unassig...@gcc.gnu.org ReportedBy: maxim.yegorush...@gmail.com I am compiling gcc-4.7.0 from sources following instructions from http://gcc.gnu.org/install/. I can compile, link and run code with the newly built g++, however, whenever I run the new ar or nm they respond with the following error message: $ /usr/local/ots/gcc/bin/gcc-ar47 /usr/local/ots/gcc/bin/gcc-ar47: Cannot find plugin $ /usr/local/ots/gcc/bin/gcc-nm47 /usr/local/ots/gcc/bin/gcc-nm47: Cannot find plugin Ian Lance Taylor in http://gcc.gnu.org/ml/gcc-help/2012-04/msg00286.html suggested that make_relative_prefix() returns NULL and that causes the problem. My configure invocation is as follows: ../gcc-4.7.0-src/configure --prefix=/usr/local/ots/gcc --program-suffix=47 --disable-libunwind-exceptions --with-system-zlib --enable-__cxa_atexit --enable-checking=release --disable-multilib --with-gmp-include=/usr/local/ots/gcc/include --with-mpfr-include=/usr/local/ots/gcc/include --with-mpc-include=/usr/local/ots/gcc/include --with-ppl-include=/usr/local/ots/gcc/include --with-cloog-include=/usr/local/ots/gcc/include --with-gmp-lib=/usr/local/ots/gcc/lib64 --with-mpfr-lib=/usr/local/ots/gcc/lib64 --with-mpc-lib=/usr/local/ots/gcc/lib64 --with-ppl-lib=/usr/local/ots/gcc/lib64 --with-cloog-lib=/usr/local/ots/gcc/lib64 --enable-languages=c,c++,fortran,lto --enable-plugin --enable-initfini-array
