I am trying to compile the ruby Interbase module, but failing. when I try : ruby extconf.rb, I get the following error: checking for main() in gdslib.lib… no checking for main() in gds.lib… no checking for main() in fbclient\_ms.lib… no \*\*\* extconf.rb failed \*\*\* Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. someone had this problem ? ---

If you don’t have VC6 already, it’s hard to obtain. There’s a free VC8 out there, but it won’t work. Mingw is free. 2. libraries and headers for interbase - I won’t help you here. To compile from command line with VC6, there’s a batch file called vcvars32.bat that sets the required environment (search paths, include paths, etc.). So you basically start cmd, run vcvars32 and then you are prepared to compile the extension by calling mkmf or whatever is needed. J.
