source: trunk/third/xalf/ltconfig @ 16240

Revision 16240, 92.1 KB checked in by rbasch, 24 years ago (diff)
Changes to support preload on IRIX, using _RLDN32_LIST. Hack build system to pass -init <function> argument to the linker, since libtool does not seem to support passing extra arguments to the linker when building a shared library. Eliminate buffer overrun in restore_env() (was not allocating enough space for the new environment string). Fix removal of LD_PRELOAD from the environment (search for foo.so, not foo.so.0).
