I've been trying to get wine to compile with GSM and haven't had any luck, I downloaded the most recent GSM library from http://www.quut.com/gsm/ and manually modified the Makefile to have it install to proper folders.. installed.. and heres proof that files are there in my /usr/lib folder! Code: -r--r--r-- 1 root root 53506 2010-05-14 01:40 /usr/lib/libgsm.a lrwxrwxrwx 1 root root 11 2010-05-14 01:45 /usr/lib/libgsm.so -> libgsm.so.1 and even during compile it recognizes the headers: Code: ./configure | grep gsm checking gsm.h usability... yes checking gsm.h presence... yes checking for gsm.h... yes checking gsm/gsm.h usability... yes checking gsm/gsm.h presence... yes checking for gsm/gsm.h... yes checking for -lgsm... not found configure: libgsm development files not found, gsm 06.10 codec won't be supported. Dunno what I'm missing here!
