I am trying to rebuild our internal libraries on rhel 8, with gcc/g++ 8.3.1. The build completed. But cannot be loaded by the application due to the fact that the "_init" symbol is missing/removed from the shared library. We make the following all to get more information from the library.
dlsym( libHandle, (const char*) "_init" )
and it returns null with the new build.
For all build from rhel 7 and before this can be verified with "nm" command, e.g.
nm -D "mylib.so" | grep "_init"
000000000032b6b0 T _init
However, when run the same command with lib built on rhel 8, nothing was found.
Is there a way to force the link to export "_init" symbol explicitly?
