No I was thinking of a dependent library list, after building mariadb on linux, in the storage/federated/.libs directory, there is ha_federated.so, the shared library and there is ha_federated.la, the libtool library file which contains: dependency_libs=' -L/wsp/sje/mariadb/linux/obj/libservices -lmysqlservices -lcrypt -lnsl -lpthread -lrt' I think this causes libtool, when building something that uses ha_federated.so to also link in libmysqlservices (and crypt, etc). libmsqlservices would only need to be PIC if it were copied into ha_federated.so and I don't think that is happening is it? If so then it would need to be PIC and with my build, the libsqlservices code is not compiled with the PIC options. > In MySQL 5.5, linking static to shared feature was used extensively (as a > replacement for libtool's "convenience libraries", static library was > compiled with platform dependent PIC flag), and it worked on all major > Unixes, I'm pretty sure it worked on HPUX/Itanium. > > I think the trick for Maria 5.3 could be to compile the sqlservices library > with the PIC flag (+Z or +z or something similar, if I recall this > correctly).

I think compiling with PIC should only be needed if libsqlservices code is intended to be linked into a shared library and I am not sure if that is the case or not. Here is the error message that libtool gives me during the build: *** Warning: linker path does not have real file for library -lmysqlservices. *** I have the capability to make that library automatically link in when *** you link to this library. But I can only do this if you have a *** shared version of the library, which you do not appear to have *** because I did check the linker path looking for a file starting *** with libmysqlservices and none of the candidates passed a file format test *** using a file magic.
