Dear GPC, The African Chief maintains the Windows version of GPC, now using 20070904 sources. Adriaan maintains the MacOS version, now using 20070904 sources. I think the outstanding question for Prince and me is the Linux version. There is no binary distribution of the 20070904 GPC that I can find. I use the 20041218 version on Linux. I suppose most Linux users are happy to compile GPC from sources. But I'm not a Linux expert: I just port my code to Linux for my Linux users. So I'm stuck with 20041218, and my code has to remain compatible with the older GPC. (I have a bunch of compiler directives to get the module names right.) Suppose I wanted to compile the 20070904 sources on Linux. How would I go about it?
