Leif Salomonsson wrote ECX as a closed-source AmigaE compiler for PowerPC Amiga-likes (starting with MorphOS) and classic Amiga. Several years later he discontinued development and released the source code of the compiler, written in ECX as a self-hosted development system.

EEC is a fork of it, hosted on GitHub, that compiles all ECX sources. The intended purpose is to parallel E-VO on the classics whose compiler is developed in 68k Assembly and is based on generations of AmigaE after Dr. Wouter van Oortmerssen left the Amiga scene in similar fashion to Leif, leaving the Assembly source to AmigaE.

If you know anything about Leif's work on ECX, please share it in the comments below or in the EEC discussion board on GitHub. There are still a few bugs left but without the help of knowledgeable developers it will once again languish in a bit-bucket. Bug reports can be made to the EEC issue tracker on GitHub. Thanks to D. M. Coles, the author of E-VO, the EEC sources compile themselves and the demo programs that came with ECX.
