2000-06-09 Ulrich Drepper <drepper@redhat.com> Rewrite error message handling. * elf/dl-deps.c (_dl_map_object_deps): Pass new parameter to _dl_catch_error. * elf/dl-error (struct catch): Add objname member. (_dl_signal_error): Take new parameter with object name. When passing message on simply store object name and duplicate error message. (_dl_catch_error): Take new parameter. Store object name in the place pointed to. * include/dlfcn.h: Adjust _dl_catch_error prototype. * sysdeps/generic/ldsodefs.h: Adjust _dl_signal_error prototype. * elf/dl-libc.c (dlerror_run): Pass new parameter to _dl_catch_error. * elf/dl-open.c (_dl_open): Likewise. * elf/rtld.c (dl_main): Likewise. * elf/dl-close.c: Mark error messages with N_(). * elf/dl-deps.c: Likewise. * elf/dl-error.c: Likewise. * elf/dl-load.c: Likewise. * elf/dl-open.c: Likewise. * elf/dl-reloc.c: Likewise. * elf/dl-support.c: Likewise. * elf/dl-sym.c: Likewise. * elf/dl-version.c: Likewise. * elf/dl-lookup.c: Add comments about problems with error message translations. * elf/dl-reloc.c: Likewise. * elf/dl-version.c: Likewise.
