You need gcc version 2.0 or later to compile gforth.
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.
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 GCC=<whatever you call your gcc>
Now you can check whether your shiny new Forth system works. Say
To make the documentation, type
make -k gforth.info gforth.ps html
If everything is allright, you may want to install gforth. Type
You may want to override the defaults for the directories. E.g., if
you want to install in the /gnu hierarchy instead of in the default
/usr/local hirarchy, say
make install prefix=/gnu
Alternatively, you can specify the prefixes with configure.
