In the library .../lib64/libgfortran.a, the 4.1.2 version has a routine _gfortran_copy_string
in the strong_intrinsics.o component. For the same 4.2.1 library there is no corresponding entry point. It appears that codes compiled with 4.1.2 generate internal calls to this entry point. Attempting to link a library built with 4.1.2 and a code compiled and linked with the 4.2.1 compiler results in an "undefined reference" message from the loader for _gfortran_copy_string. Is it by design that codes compiled with 4.1.2 cannot be linked with 4.2.1? Is it a viable workaround to manually extract the string_intrinsic.o component from the old libgfortran.a file and insert it into the new libgfortran.a library, replacing the current version? -- Summary: _gfortran_copy_string missing in libgfortran.a Product: gcc Version: 4.2.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: longb at cray dot com GCC build triplet: x86_64-suse-linux GCC host triplet: x86_64-suse-linux GCC target triplet: x86_64-suse-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33647
