./configure |
|
|
configure has the following useful parameters: |
(see Section Configuration Options below for details). |
--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 |
|
|
|
./configure --prefix=/gnu |
|
|
|

|
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. |

Configuration Options |
|
|
|
If you use GNU make, you can build in a directory different from the |
|
source directory by changing to the build directory and invoking |
|
configure thus: |
|
|
|
$srcdir/configure |
|
|
|
where $srcdir is the source directory. (Note that we tested this only |
|
for installation; i.e., if you want to hack the Gforth sources, you |
|
should probably build in the source directory). |
|
|
|
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. |
|
|
|
The file Benchres shows which combination of the -enable options we |
|
tried gave the best results for various machines. |
|
|
|
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 |
|
hierarchy, say |
|
|
|
./configure --prefix=/gnu |
|
|
|
Moreover, if your GCC is not called gcc (but, e.g., gcc-2.7.1), you |
|
should say so during configuration. E.g.: |
|
|
|
env CC=gcc-2.7.1 ./configure |
|
|
|
You can also pass additional options to gcc in this way, e.g., if you |
|
want to generate an a.out executable under Linux with gcc-2.7.0: |
|
|
|
env "CC=gcc -b i486-linuxaout -V 2.7.0" ./configure |
|
|
|
You can change the sizes of the various areas used in the default |
|
image `gforth.fi' by passing the appropriate Gforth command line |
|
options in the FORTHSIZES environment variable: |
|
|
|
env "FORTHSIZES=--dictionary-size=256k --data-stack-size=16k --fp-stack-size=16k --return-stack-size=16k --locals-stack-size=16k" ./configure |
|
|
|
The line above reaffirms the default sizes. Note that the locals |
|
stack area is also used as input buffer stack. |

2) "%s: Checksum of image ($13579b) does not match the executable ($2468a) |
|

|
|
|
A fixed-address image is not only fixed with respect to its base |
|
address, but also with respect to certain addresses in the gforth |
|
executable and the threading method. These things are encoded in a |
|
checksum. |
|
|
|
If the checksum of the executable and the checksum of the image are |
|
not equal, you get the message above. This can be caused, e.g., by |
|
trying to run an image produced for a direct threading system on an |
|
indirect threaded system. |
|
|
|
Chances are that you unintentionally tried to execute an image from |
|
the wrong directory. As a remedy, you can specify Gforth's search |
|
path with the "-p" command line option and with the GFORTHPATH |
|
environment variable. |
|
|
|
On the other hand, if you need to solve the problem by creating a new |
|
fixed-address image, you can use the steps described above. |
