Preventing symbols from being stripped in IBM Visual Age C/C++ for AIX
- by smountcastle
I'm building a shared library which I dynamically load (using dlopen) into my AIX application using IBM's VisualAge C/C++ compiler. Unfortunately, it appears to be stripping out necessary symbols:
rtld: 0712-002 fatal error: exiting.
rtld: 0712-001 Symbol setVersion__Q2_3CIF17VersionReporterFRCQ2_3std12basic_stringXTcTQ2_3std11char_traitsXTc_TQ2_3std9allocatorXTc__ was referenced
from module ./object/AIX-6.1-ppc/plugins/plugin.so(), but a runtime definition
of the symbol was not found.
Both the shared library and the application which loads the shared library compile/link against the static library which contains the VersionReporter mentioned in the error message.
To link the shared library I'm using these options: -bM:SRE -bnoentry -bexpall
To link the application, I'm using this option: -brtl
Is there an option I can use to prevent this symbol from being stripped in the application? I've tried using -nogc as stated in the IBM docs, but that causes the shared library to be in an invalid format or the application to fail to link (depending on which one I use it with).
