Preliminary version You need gcc version 2.0 or later to compile gforth. First, type configure configure has the following useful parameters: -direct-threaded: setup for a direct threaded interpreter; this is faster on many machines, but needs special support. Unsupported machines will ingore this switch. On some CISC machines, direct threading isn't an advantage over indirect threading. -without-debug: omits the -g switch and creates smaller images on machines where "strip" has problems with gcc style debugging informations. --help: tells you about other parameters. Now type make If your make has trouble with the Makefile, "make gforth" might work. If your installed gcc isn't called "gcc" (eg. called "gcc-2.6.1"), type make CC= instead. To make the documentation, type make -k gforth.info gforth.ps html
