Building CPhone
Make certain that you have version 3.x (or later) of QT installed on your system and a current version of pwlib and OpenH323. The CVS version of cphone requires a version of OpenH323 greater than 1.9.5 and a version of pwlib greater than 1.3.5 (2003-05-20: Currently that means that you must use a CVS version of openh323 and pwlib)
Follow the instructions in tha tar balls, and build pwlib, then openh323.
With one exception, you need to turn off memory checking in pwlib+openh323.
To turn off memory checking in pwlib+openh323, just
run the optimised (or release) version of the pwlib+openh323 libraries.
OR,
if you want to run the debug version of the pwlib+openh323 libraries,
you can remove the define MEMORY_CHECK from the windows project files for these libraries,
and under unix, you can do "export MEMORY_CHECK=0" before issuing the make debug command.
You can get more detail at the source for the pwlib+openh323 code, at pwlib+openh323 homepage.
