Asunto: Re: [h323plus] Compiling PTLib 2.10.1 in Ubuntu 11

Hi,

I just tried it and on Ubunto 11.04 (32bit) and I had no trouble
compiling PTLib 2.10.1.

I have a minimal install of Ubuntu and added pkg-config, automake, flex,
bison and gcc, but I think that was it. The I set set PTLIBDIR, did a ./configure
and make optnoshared. No problems, I also tried a few of the samples.

If you continue to have problems with PTLib, you should post on the
OPAL mailinglist (opalvoip-user@lists.sourceforge.net) to reach the
PTLib developers.

Regards,
Jan
