             Summary: shared library loading depends on environment variable updates
                 Key: MESOS-3725
                 URL: https://issues.apache.org/jira/browse/MESOS-3725
             Project: Mesos
          Issue Type: Bug
          Components: modules, stout
            Reporter: James Peach


{{ModuleTest::SetUpTestCase()}} and the various {{libraries::paths()}} is stout assume that updating {{LD_LIBRARY_PATH}} or {{DYLD_LIBRARY_PATH}} is sufficient to alter the search path used by dlopen(3). It is not; those environment variables are only bound at program load.

My preference is to fix this by requiring the clients of {{DynamicLibrary}} to always pass in an absolute path and to remove all mention of these environment variables.

FWIW, the tests in {{ModuleTest::SetUpTestCase()}} only work because the libtool wrapper script sets up the library path to the expected value prior to running the tests.
