Hello! Looks like h323 compiling is FAQ, but I didn't found an answer... The same problem with 0.6.5 and 0.7.1: gcc -Wall -pipe -Wall -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -D_REENTRANT -D_GNU_SOURCE -I/var/local/files/asterisk-1.0.5/include -I../wrapper -g -c -o chan_oh323.o chan_oh323.c chan_oh323.c: In function `oh323_call': chan_oh323.c:1454: error: structure has no member named `cid' chan_oh323.c:1454: error: structure has no member named `cid' chan_oh323.c:1456: error: structure has no member named `cid' chan_oh323.c:1468: error: structure has no member named `cid' chan_oh323.c:1470: error: structure has no member named `cid' chan_oh323.c:1470: error: structure has no member named `cid' chan_oh323.c:1472: error: structure has no member named `cid' chan_oh323.c:1484: error: structure has no member named `cid' And there is really no cid in ast_channel ... How can I compile h323 with Asterisk 1.0.5? Thank you!
