You need gcc version 2.0 or later to compile gforth. |
You need gcc version 2.0 or later to compile gforth. |
|
|
Create a machine description file for your machine, if necessary. |
First, type |
|
|
Make a symbolic link to machine.h, e.g. |
|
|
|
ln -s decstation.h machine.h |
./configure |
|
|
Make a symbolic link from mach32l.fs or mach32b.fs to machine.fs |
configure has the following useful parameters: |
|
--prefix=PREFIX install architecture-independent files in PREFIX |
|
[default: /usr/local] |
|
--exec-prefix=PREFIX install architecture-dependent files in PREFIX |
|
[default: same as prefix] |
|
--enable-force-reg Use explicit register declarations if they appear in |
|
the machine.h file. This can cause a good speedup, |
|
but also incorrect code with some gcc versions on |
|
some processors (default disabled). |
|
--enable-direct-threaded Force direct threading. This may not work on |
|
some machines and may cause slowdown on others. |
|
(default processor-dependent) |
|
--enable-indirect-threaded Force indirect threading. This can cause a |
|
slowdown on some machines. |
|
(default processor-dependent) |
|
--with-debug specifies option -g to compile with debug info (default) |
|
--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 you don't like the defaults for the installation directories, you |
|
should override them already during configure. E.g., if you want to |
|
install in the /gnu hierarchy instead of in the default /usr/local |
|
hirarchy, say |
|
|
Edit the Makefile (in particular the SWITCHES variable) |
./configure --prefix=/gnu |
|
|
Now you can type |
After, configuration, type |
|
|
make |
make |
|
|
|
If your make has trouble with the Makefile, "make gforth" might work. |
|
|
|
If your installed gcc isn't called "gcc" (e.g., called "gcc-2.6.1"), type |
|
|
|
make GCC=<whatever you call your gcc> |
|
|
|
instead. |
|
|
|
Now you can check whether your shiny new Forth system works. Say |
|
|
|
make test |
|
|
|
To make the documentation, type |
|
|
|
make -k gforth.info gforth.ps html |
|
|
|
If everything is allright, you may want to install gforth. Type |
|
|
|
make install |
|
|
|
You have to make an entry in the info directory file manually. Also, |
|
you have to install gforth.ps and html yourself. |
