> When trying to link another shared library against libactivemq-cpp.a on
> 64-bit Fedora Core 6, I get the following error:
> /usr/bin/ld: libactivemq-cpp.a(ActiveMQConnectionFactory.o): relocation
> R_X86_64_32 against `a local symbol' can not be used when making a shared
> object; recompile with -fPIC
> libactivemq-cpp.a: could not read symbols: Bad value
> Adding -fPIC to the CXXFLAGS seems to do the trick:
> Index: configure.ac
