When I try to compile Gforth 0.7.0, I get the following error:
$ ./configure
$ make
#compiling…
Undefined symbols:
"_main", referenced from:

ld: symbol(s) not found

You need to configure with a gforth in $PATH to build this part
make[3]: *** [kernl16b.fi-] Error 1
make[2]: *** [gforth-ll] Error 2
make[1]: *** [optgforth] Error 2
make: *** [gforth] Error 2
[22:16:01] gforth-0.7.0$
I get the same error when installing via ports. I imagine the problem is that Gforth is written, at least partially in Forth, so how do I install it without first installing it (or is the problem something else)?
I am using Mac OS 10.6.
During the configure, I got the message:
...
checking how to invoke m4... m4 -s
checking for gforth... echo "You need to configure with a gforth in \$PATH to build this part" && false
checking for ./arch/386/asm.fs... yes
...
I also found that when I built with plain GCC (in 64-bit mode), things went horribly wrong during the compilation (complaints about mis-specified registers in, I assume, assembler inserts). But when I reconfigured with:
CC="gcc -m32" ./configure --prefix=$HOME
I still got the warning about 'gforth' but the rest of the compilation succeeded. The install came up with a warning about 'chcon' not working, but the error was ignored.
After installation, I was able to type:
