In the compilation oflibopen-pal.soand libopen-palmca_common_ucx.so, the static library libmca_memory.a is linked. Although libopen-palmca_common_ucx.so is dlopen, the flag is set to RTLD_GLOBAL.

libopen-palmca_common_ucx.so only uses symbol opal_memory_base_framework, and the code has defined extern, so you can directly use the definition in libopen-pal.so.
