Yes,
I am using autotools.. I run ./configure --disable shared or even modifying Makefile.am... in all these ways the static library is built (libfreeswitch.a)  but when linking with freeswitch (bin) I got "undefined symbols" 

For instance, the symbol _switch_api_execute or _switch_log_printf are given as undefined  but 

otool -v -S -a libfreeswitch.a | grep _switch_api_execute
libfreeswitch_la-switch_loadable_module.o _switch_api_execute

otool -v -S -a libfreeswitch.a | grep _switch_log_printf
libfreeswitch_la-switch_log.o _switch_log_printf

I also got this warning from the linker:
ld warning: in /freeswitch/.libs/libfreeswitch.a, file is not of required architecture
but
lipo -info libfreeswitch.a
input file libfreeswitch.a is not a fat file
Non-fat file: libfreeswitch.a is architecture: i386

as expected

You would use glibtool to accomplish this and us the .la file as far as I know.
