Hi, just playing with building FreeSwitch on a Solaris 10 box and am hitting a link error when building the target '.libs/freeswitch' Undefined first referenced symbol in file make_mask32 freeswitch-switch.o ld: fatal: Symbol referencing errors. No output written to .libs/freeswitch Looking at the source, make_mask32 seems to be defined in the spandsp/src/bit_operations.c file, which isn't involved in the linking at this point. Building with Sun Studio 12, just in case it's of any interest. I'll try and move the make_mask32 function in to the library and see if that cures the problem. Thought I'd ask here, as this kind of thing should appear on most platforms if it really is a problem - meaning it might be something at my end. m (Tried posting this to the -dev alias, but I'm guessing it's held by the moderators; I've put the 'make_mask32' function into the freeswitch library and now the compile works ok) ----- Marty Lee e: marty@maui-systems.co.uk Technical Director v: +44 845 869 2661 Maui Systems Ltd f: +44 871 433 8922 Scotland, UK w: http://www.maui-systems.co.uk
