Question: Unresolved symbols 

Forum: PCMCIA Installation and Configuration Issues

I installed the PCMCIA modules from 3.1.3, but when I start my computer they fail to load. When I run /etc/init.d/pcmcia start, I get the following error messages: Starting PCMCIA services: modules/lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol strcat /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol inb /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol ioremap /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol __constant_memcpy /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol __constant_c_memset /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol ffs /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol strcmp /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol strcpy /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol __memcpy /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol strlen /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol signal_pending /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol __constant_c_and_count_memset /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol strncpy /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol strncmp /lib/modules/2.2.13/pcmcia/pcmcia_core.o: unresolved symbol __memset_generic etc. Any ideas?

Bad CFLAGS during compilation Re: Question: Unresolved symbols (Joseph Turian) Date: 1999, Nov 01 From: David Hinds <dhinds@pcmcia.sourceforge.org>

These missing symbols are all inline functions, that only get inlined properly if compiled with optimization. So, the quick workaround is to unset the CFLAGS variable before building PCMCIA. I'm fixing the Makefiles for 3.1.4 to not allow CFLAGS overrides from the environment. It was meant to be a feature, but I've never really used it, and it confuses people. -- Dave
