# $Source$ # $State$ # $Revision$ THE AMSTERDAM COMPILER KIT V6.0pre2 =================================== © 1987-2005 Vrije Universiteit, Amsterdam 2007-04-24 INTRODUCTION ============ The Amsterdam Compiler Kit is a complete compiler toolchain consisting of front end compilers for a number of different languages, code generators, support libraries, and all the tools necessary to go from source code to executable on any of the platforms it supports. This is an early prerelease of the upcoming version 6.0 release. Not a lot is supported, the build mechanism needs work, and a lot of things are probably broken. However, what's there should be sufficient to get things done and to evaluate how the full 6.0 release should work. SUPPORT ======= Languages: ANSI C, Pascal, Modula 2. K&R is supported via the ANSI C compiler. Platforms: pc86 produces bootable floppy disk images for 8086 PCs linux386 produces ELF executables for PC Linux systems INSTALLATION ============ The version 6.0 build mechanism has been completely rewritten and is based around the Prime Mover build tool (see http://primemover.sf.net for more information). Installation ought to be fairly straightforward. Requirements: - an ANSI C compiler. Currently, I'm afraid, it's hard-coded to use gcc. To change, try changing the variable definitions in first/c.pm. This also needs to be available as 'cc' from the shell. - about 20MB free in /tmp (or some other temporary directory). - about 6MB in the target directory. Instructions: - edit config.pm. There's a small section at the top containing some editable variables. Probably the only one you may want to edit is PREFIX, which changes where the ACK installs to. - Run: ./pm configure ...from the command line. This will write out a configuration file. - Run: ./pm ...from the command line. This will actually do the build. This takes about two minutes on my 1.6GHz Athlon Linux machine and about 30 on my 166MHz Pentium OpenBSD machine. - Run: ./pm install ...from the command line (possibly with sudo). This will install the built ACK into whatever directory you nominated in PREFIX. The ACK should now be ready to use. USAGE ===== Currently I haven't sorted out all the documentation --- it's supplied in the distribution, but not all of it gets installed yet --- so here is a quickstart guide. The main command to use is 'ack'. This invokes the compiler and the linker. Some useful options include: -m build for the specified platform -o specifies the output file -c produce a .o file -c.s produce a .s assembly file -O enable optimisation -ansi compile ANSI C (when using the C compiler) build file ack figures out which language to use from the file extension: .c C (ANSI or K&R) .b Basic .mod Modula-2 .ocm Occam 1 .p Pascal .o object files .s assembly files For further information, see the man page (which actually does get installed, but is rather out of date). There are some (known working) example programs in the 'examples' directory. A sample command line is: ack -mlinux386 -O examples/paranoia.c GOTCHAS ======= There are some things you should be aware of. - Look at plat/linux386/README and plat/pc86/README for information about the two supported platforms. - The library support is fairly limited; for C, it's at roughly the ANSI C level, and for the other languages it's similar. - When compiling languages other than C, the ACK will usually look at the first character of the file. If it's a #, then the file will be run through the C preprocessor anyway. - BSD systems may need to up the number of file descriptors (e.g. 'ulimit -n 200') before the ACK will compile. - The ACK uses its own .o format. You won't be able to mix the ACK's object files and another compiler's. DISCLAIMER ========== The ACK is mature, well-tested software, but the environment in which it was developed for and tested under is rather different from that available on today's machines. There will probably be little in the way of logical bugs, but there may be many compilation and API bugs. If you wish to use the ACK, *please* join the mailing list. We are interested in any reports of success and particularly, failure. If it does fail for you, we would love to know why, in as much detail as possible. Bug fixes are even more welcome. The ACK is licensed under a BSD-like license. Please see the 'Copyright' file for the full text. You can find the mailing list on the project's web site: http://tack.sourceforge.net/ Please enjoy.
