guide to compile your own version of O2EM:

 

Step 1: downloading the necessary files:

----------------------------------------

O2EM Source Code: http://o2em.sourceforge.net/

(Download the Windows Source Code of the latest version)

 

the C-Compilers recommended in the doc-File:

MinGW: http://sourceforge.net/projects/mingw/

Download this file:

http://prdownloads.sourceforge.net/mingw/MinGW-5.0.2.exe?download

and download the mingw32-make, which is contained in this file:

http://prdownloads.sourceforge.net/mingw/MinGW-3.1.0-1.exe?download

(I have tried the other mingw32-make which are offered seperatly, but the one included in this package seems to be the only one able to compile the allegro package ... if you find out something different, please LET ME KNOW !!!)

 

the Allegro-Library: http://alleg.sourceforge.net/

Download this file:

http://prdownloads.sourceforge.net/alleg/all420.zip?download

 

the Direct-X mgw File from the same page:

http://alleg.sourceforge.net/files/dx70_mgw.zip

 

 

Step 2: Install the Compiler

----------------------------

ok, first install the MinGW (base install is enough) in a directory of your choice ... if you choose a directory with spaces (eg. "Program Files") you may have to use the 8.3 Filename in later steps. After the installer downloads all files (should be 4), copy all of them in your MinGW directory (overwrite existing files)

Include the bin\ directory of MinGW in your path (Control Panel/System/Environmet Variables -> append to the PATH Variable: C:\Program Files\MinGW\bin;

Unpack "make" into the compiler directory

If you enter "gcc" in a command line window in any directory, you should NOT get a message that the file is not found !! (Restart may be necessary)

If you enter "mingw32-make" in a command line window in any directory, you should NOT get a message that the file is not found !! (Restart may be necessary)

 

 

Step 3: Installing Allegro for MinGW

------------------------------------

Unpack the allegro files into a subdirectory of your MinGW directory.

Unpack the "Direct-X" File into your Compiler (=MinGW) directory, NOT in the allegro subdirectory.

Next set the Enviroment Variable "MINGDIR" to you MinGW Directory. To do so go to Control Panel/System/Environmet Variables and add the Variable "MINGDIR" with the Value of your directory. ATTENTION: If you used a space you have to use the 8.3 Filename now, eg.: C:\PROGRA~1\MinGW

 

Next: enter the allegro directory and enter the following commands inside the command window:

fix mingw32

mingw32-make

mingw32-make install

 

ok, thatís it, the compiler is now setup to use the allegro libraries and should be able to compile o2em now ... which leads us to

 

 

Step 4: Compiling o2em

----------------------

go to the o2emsrc directory and rename the file "makefile.mgw" to "makefile"

Another thing to do: in the makefile is a target "clean", which uses "rm -f" a command, which is not known to windows, so change that to "del -f"

 

use

"make clean" to clean the compiled files

"make all" to build o2em.exe and dis48.exe

 

if all went well, you should have compiled yourself an o2em now ...
