- // libjawt.so must be installed in GCJ's versioned directory and not
- // the main library directory so that it doesn't override other
- // libjawt.so implementations. Programs that use the AWT Native
- // Interface contain a JNI library that links to libjawt.so. We do
- // not want to require that users explicitly add GCJ's versioned
- // directory to LD_LIBRARY_PATH when running such programs.
-
- // Simply adding GCJ's versioned directory to the module load path
- // does not solve this problem since libltdl searches its module
- // load path only for object that it will dlopen; dependencies of
- // these dynamically loaded objects are searched for in
- // LD_LIBRARY_PATH.
-
- // In addition, setting LD_LIBRARY_PATH from within the current
- // process does not alter the dependency search path, since it is
- // computed on startup. This behaviour makes sense since
- // LD_LIBRARY_PATH is designed to allow users to override the path
- // set by a program. This re-spawning trick makes it impossible to
- // override, using LD_LIBRARY_PATH, the versioned directories
- // searched by gij.
-
- // Check if LD_LIBRARY_PATH is already prefixed with
- // GCJ_VERSIONED_LIBDIR. If not, export LD_LIBRARY_PATH prefixed
- // with GCJ_VERSIONED_LIBDIR and re-spawn gij.
