Building with Opal

[jameswillhoite]

I'm hoping you might be able to help. I've been trying for days to build a T38Modem on Ubuntu 22.04.3. I've been successful with H323+ 1.28.0, ptlib-2.10.9.5 and T38Modem-2.0.0 with Hylafax-6.0.7. It is able to attempt to talk with our Sip but doesn't accept the invite. I'm assuming if I can get Opal built and use that, then it might just work. I've stumbled upon your GitHub and hopeful to see recent work being done. I saw the previous Issue state they are using opal 3.18.7, ptlib 2.18.7 but I've been unsuccessfull building that version of Ptlib with an error: 'SetAt' was not declared in this scope. Would you have any pointers? What Libraries are typically required besides flex and bison?

Thanks!

I built ptlib with this script.

Edit: The original script built ptlib fine but it wasn't usable by opal or t38modem. Needed more work to compile the whole thing. Included are the rest of the scripts and patch. I have more patches in Arch Linux t38modem to get it to work. Don't know if this Ubuntu compile needs them.

This worked! Thank you @severach for this script. Everything built the way it was supposed to.
