GNU Compiler Collection

GNU GCC Logo

The GNU Compiler Collection or GCC contains what is possibly the technically most advanced currently maintained C/C++ compiler for OS/2 and eCS, generating good code and supporting the latest standards. Because it is available and maintained for a large number of operating systems it is also for many the first choice when it comes to writing portable code. However it should be noted that many of the operating systems listed as being supported by GCC have had their support removed in the 4x branch or earlier, meaning that to archive full portability you may have to keep 2.x (EMX) or 3.x branches of GCC going if you are targeting some of the less used OS's. In addition systems that are not UNIX like may need emulation layers and libraries and in some cases such as with Microsoft Windows their uses can be clunky or even problematic.

Source and References

• For a long time the EMX collection was the preferred CPP port for OS/2 developers, it still is to a degree preferable to the later DJGPP for DOS development work even though the latter collection supports newer versions of GCC.
• Innotek GCC was also available but Innotek is no longer in business since it was acquired by Sun Microsystems.

Version

• Latest OS/2 version: GCC - GNU C Compiler v4.9.2 (2014-12-18) or test version v5.1.0 (2015-04-26)
