###NOTE: compile completed without errors.

root@asterisk:/usr/src/openh323# make opt
root@asterisk:/usr/src/openh323# cd
###NOTE: compile completed without errors.
###I set OPENH323DIR=/usr/src/openh323, put /usr/src/openh323 in /etc/ld.so.conf, ran ldconfig
root@asterisk:/usr/src# cd asterisk-1.2.8
root@asterisk:/usr/src/asterisk-1.2.8# apt-get install openssl libssl-dev expat libexpat-dev
###NOTE at this point there are three options I tried: 
### 1. Build asterisk without modification
### 2. Add chan_h323.so into channels/Makefile's CHANNEL_LIBS and make from /usr/src/asterisk
### 3. build chan_h323.so in /usr/src/asterisk-1.2.8/channels/h323
### Option #1 completes successfully without building any h323 modules.
### I will now procede to paste the last parts of the build for #1, and the whole build for #2.
### In order to save time, for purposes of creating this log I only did make and make clean in
### /usr/src/asterisk-1.2.8/channels
