This means that, if your application builds shared libraries +and your MakeMaker application links to them, that the absolute paths of the +libraries in the build tree will be inserted into the RPATH header of all +MakeMaker generated binaries, and that such binaries will be unable to link +to these libraries if they do not still reside in the build tree directories +(unlikely) or in the system library directories (/lib or /usr/lib), regardless +of any LD_LIBRARY_PATH setting. So if you specified -L../mylib -lmylib , and +your 'libmylib.so' gets installed into /some_directory_other_than_usr_lib, +your MakeMaker application will be unable to link to it, even if LD_LIBRARY_PATH +is set to include /some_directory_other_than_usr_lib, because RPATH overrides +LD_LIBRARY_PATH. + +So for Red Hat MakeMaker builds LD_RUN_PATH is NOT generated by default for +every link. You can still use explicit -rpath ld options or the LD_RUN_PATH +environment variable during the build to generate an RPATH for the binaries. + +You can set the USE_MM_LD_RUN_PATH attribute to 1 on the MakeMaker command +line or in the WriteMakefile arguments to enable generation of LD_RUN_PATH +for every link command. + +USE_MM_LD_RUN_PATH will default to 1 (LD_RUN_PATH will be used) IF the +$USE_MM_LD_RUN_PATH environment variable is set during a MakeMaker run. + =item VENDORPREFIX Like PERLPREFIX, but only for the vendor install locations.
