undefined reference to symbol 'pthread_create@@GLIBC_2.1'

Hi !
I try to build FGCOM on kUbuntu 13.04 and get this error:

Code: Select all

Linking CXX executable fgcom
/usr/bin/ld: libiaxclient_lib.a(iaxclient_lib.c.o): undefined reference to symbol 'pthread_create@@GLIBC_2.1'
/usr/bin/ld: note: 'pthread_create@@GLIBC_2.1' is defined in DSO /lib/i386-linux-gnu/libpthread.so.0 so try adding it to the linker command line
/lib/i386-linux-gnu/libpthread.so.0: could not read symbols: Invalid operation

my fix/workaround for this:

I download_and_compiled the latest git version("2.99"): fgcom is included and works nicely in a first test

fgfs --enable-fgcom
