Hi, I tried to compile newest master branch and this failed with error: CC libopenconnect_la-dtls.lo dtls.c: In function 'dtls_try_handshake': dtls.c:341:3: error: 'c' undeclared (first use in this function) c = openconnect_get_dtls_compression(vpninfo); ^ dtls.c:341:3: note: each undeclared identifier is reported only once for each function it appears in make[2]: *** [libopenconnect_la-dtls.lo] Error 1 make[2]: Leaving directory `/home/emanuel/openconnect' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/emanuel/openconnect' make: *** [all] Error 2 I believe that this could be fixed by adding something along below line dtls.c:334 file const char *c = NULL; Sorry that I didn't proposed the change via git - I don't know what's your pull request flow. Thanks in advance, Kamil Skowron
