在没有Gforth的情况下编译Gforth？

Question

当我尝试编译Gforth 0.7.0时,我收到以下错误:

$ ./configure
$ make
#compiling… 
Undefined symbols:
  "_main", referenced from:
      start in crt1.10.6.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make[3]: *** [gforth-ll] Error 1
./preforth -p ".:~+:." -e 's" mach16b.fs"' ./kernel/main.fs -e "save-cross kernl16b.fi- /usr/local/bin/gforth-0.7.0 bye"
You need to configure with a gforth in $PATH to build this part
make[3]: *** [kernl16b.fi-] Error 1
make[2]: *** [gforth-ll] Error 2
make[1]: *** [optgforth] Error 2
make: *** [gforth] Error 2
[22:16:01] gforth-0.7.0$ 

通过端口安装时出现同样的错误.我想问题是Gforth是写的,至少部分是在Forth中,所以如何在没有先安装它的情况下安装它(或者是其他问题)？

我使用的是Mac OS 10.6.

在配置期间,我收到了消息:

...
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
...

我还发现,当我用普通GCC内置(在64位模式下),事物的编译过程中去可怕的错误(约误指定的,我认为,汇编器插入寄存器的投诉).但是当我重新配置:

CC="gcc -m32" ./configure --prefix=$HOME

我仍然收到关于'gforth'的警告,但其余的编译成功了.安装提出了关于'chcon'无效的警告,但错误被忽略了.

安装后,我能够输入:
