|WARNING! I no longer have time to maintain ezm3 effectively. I try to keep it working on FreeBSD/i386 platforms, but I can no longer maintain it on Linux or other platforms. In particular, ezm3 1.2 will not build on Fedora Core 5 systems. If you want to run CVSup on a non-FreeBSD platform, you may have better luck using the CM3 compiler instead of ezm3.|
Ezm3 1.2 is now available! This new release includes an updated code generator (based on gcc 3.2.3) which is a big step toward supporting amd64 platforms. (Sorry, they're not supported quite yet in this release.)
A few bugs have been fixed, of course. It should be easier now to build Ezm3 on the newer Linux distributions.
You must use CVSup 16.1h or later with this version of Ezm3. Earlier versions of CVSup will not build properly with Ezm3 1.2. You can get CVSup 16.1h from ftp://ftp.freebsd.org/pub/FreeBSD/development/CVSup/snapshots/.
The following old platforms, which were supported in the original Ezm3 release, are no longer supported: BSDI4, FreeBSD2, FreeBSD3, and SPARC (SunOS 4.x). If you have one of these platforms, you will need to stick with Ezm3 1.0.
Ezm3 is a simpler, more portable distribution of the Modula-3 compiler and runtime libraries. It is designed for people who would like to install CVSup on their systems as quickly and as painlessly as possible. Ezm3 is derived from the robust and comprehensive PM3 release of Modula-3. Only the components and features which are needed by CVSup were retained. Features which made the package harder to port and install were removed.
The goal of Ezm3 is for you to be able to install Modula-3 on your system in one try, without any patching or false starts.
Ezm3 is not a full release of the entire Modula-3 source base. It contains only those components which are required for building and running CVSup. If you are interested in using Modula-3 for anything except building CVSup, you might be better off using a more complete distribution such as PM3 or CM3.
Ezm3 does not bother building shared library versions of the Modula-3 runtime libraries. This means that CVSup and other programs you build with Ezm3 will be self-sufficient. They will run on systems which don't have Ezm3 installed.
Ezm3 does not bother trying to support Modula-3's incremental garbage collection feature. This feature is the leading cause of portability and installation problems in other distributions of Modula-3. It does not benefit CVSup, so it has been removed. As a lucky side-effect, removing the incremental GC reduces dynamic memory usage by about 25%.
Ezm3 does not try to support Windows. It is for Unix variants only.
Ezm3 should install easily on the following platforms.
