Bug ID: 66300 Summary: GCC_ENABLE_PLUGINS references undefined variables, breaking configure Product: gcc Version: 5.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: plugins Assignee: unassigned at gcc dot gnu.org Reporter: ossman at cendio dot se Target Milestone: --- The GCC_ENABLE_PLUGINS macro references the variables gcc_cv_nm and gcc_cv_objdump which will not be set outside of gcc/configure. This means that e.g. libcc1 doesn't configure properly when those variables are needed. I'm assuming this is because it was moved out of gcc/configure.ac, so I assume the fix is to move more stuff out of there. The error you get is: checking for exported symbols... /home/tltest/cenbuild/repo/rpmbuild/BUILD/gcc-5.1.0/libcc1/configure: line 14531: -T: command not found yes checking for -rdynamic... /home/tltest/cenbuild/repo/rpmbuild/BUILD/gcc-5.1.0/libcc1/configure: line 14541: -T: command not found
