Another problem with libtool, related to the above, is the handling of RPATH (needed when libraries are installed in non-standard places). Current versions of libtool incorrectly propagate the -R or -rpath options of ld into the RPATH ELF header, resulting in a library that -- while it has the correct NEEDED entries to refer to other libraries -- can't find them at runtime. Since Linux-PAM's modules directory typically is not the in the system-wide search path of the dynamic linker, this might affect us, too. -- Ingo Luetkebohle / ingo@blank.pages.de / 95428014 / | Student of Computational Linguistics & Computer Science; | Fargonauten.DE sysadmin; Gimp Registry maintainer; | FP: 3187 4DEC 47E6 1B1E 6F4F 57D4 CD90 C164 34AD CE5B
