Hi Guys.

Many thanks for your fast response, with your guide I run H323plus 1.21 & Ptlib 2.4.5 separately. But when I download Myphone 0.4 from the h323plus.org site and try to run it (with use of the source of H323plus 1.21 & Ptlib package). I had below errors in Myphone .

I need to solve this problem too. Please guide me to solve it.
