Crossgo32 is a cross-compiler built from "gcc 2.7.2.2" which uses the
|
|
Cygnus embedded libraries to create smaller binaries. Unfortunately
|
|
there is no networking support at the moment. Binaries are created in
|
|
the COFF format and a utility is provided to convert these binaries
|
|
into DJGPPv1 exe files.
|
|
|
|
The package is composed of the following utilities:
|
|
GNU`s misc. utilities binutils-2.7
|
|
The GNU's C Compiler gcc-2.7.2.2 + crosspatch
|
|
Cygnus's embedded libraries newlib-1.7.1
|
|
Cygnus's dos release utilities dosrel-1.0

Compiling your code
|
|
===================
|
|
|
|
Compiling your code is just as easy (or should that be difficult?) as
|
|
gcc. All of the go32 compiler binaries have been installed with the
|
|
i386-go32 prefix. So, if you wanted to compile a file called "hello.c"
|
|
then you might use something like:
|
|
|
|
i386-go32-gcc -o hello hello.c
|
|
|
|
This will produce a COFF binary called "hello". You will now need to
|
|
convert that binary into a EXE file so that it can be run on a DOS
|
|
machine. It's as easy as typing:
|
|
|
|
i386-go32-coff2exe hello
|
|
|
|
This will produce "hello.exe".
|
|
|
|
To run your programs you need to have a DPMI server running and the
|
|
go32.exe & emu387 files in your DOS path. Crossgo32 binaries will work
|
|
with a range of DPMI servers - I have personally had success with
|
|
Windows 95 - and there is a server available from the DJGPP web
|
|
site. The DOS files mentioned above should be in
|
|
/usr/local/share/crossgo32 (or similar on your system). Please check
|
|
the DJGPP FAQ for more information on this topic.

Related ports
|
|
=============
|
|
|
|
This cross-compiler port was originally created by Pedro Giffuni using
|
|
the Cygnus cross-compiler FAQ and mailing list postings. You will find
|
|
other ports in the collection which use the same distribution. The
|
|
intention was to create a cross-compiler kit for all platforms
|
|
emulated on FreeBSD.
|
|
|
|
If you are interested in network support and DJGPP v2 exe files,
|
|
amongst other DJGPP bits and pieces, check out the crossgo32-dgjpp2
|
|
selection of ports.
