This should be a graphical IDE which supports (at least) C. Which type of application do you want to produce? Graphical? => Galaxy, as suggested. Be prepared for sub-optimal results on most/all platforms. => Develop for main platform (alas, probably Win32) and then port using win32 kits from 3rd parties. Just plain C? => Stick to the smallest set of (Posix) system calls that you need. We develop for NT, Unix and VMS. The Unices are 99.99% identical amongst themselves. The VMS port uses the fork() and exec() emulation currently available on VMS. Works well, about 99% commonality with Unix source. NT is the odd one out for us, about 96% commonality. Use the POSIX library on VMS. Do *not* use the POSIX library on NT. Regards, Kees
