This article is the result of my exercise of trying to compile a WPS class on 2018. On this case I had choosen to compile HWMan WPS Class to learn about the build procedure.

Software Required

Tool Components Link
IBM C and C++ Compilers, Version 3.6.5‎ with fixpack 2 It contains icc.exe, alp.exe ... [1]
OS/2 Device Driver Kit On-Line This program makes a reference to "RMCALLS.H" that is included on the DDK, that is why it is required. [2]
IBM OS/2 Developer's Toolkit version 4.5 It contains nmake.exe and required libraries to compile.
emxupd.exe emxupd unlocks and replaces a DLL. [3]
HWMan Source Code The source code (WPS Class) that we are going to compile [4]

Preparing the Environment

Installing IBM C and C++ Compilers, Version 3.6.5

Installing "IBM C and C++ Compilers Version 3.6.5" can be tricky since you need Netscape navigator to work as the installer tool. The good thing is that the installer includes Netscape on the list. So you can install Netscape on ArcaOS (if you didn't install it when you install the OS) from it.


The install procedure is just straightforward. You can only install the "basic" components of this tool and it will work for this exercise.

Once it finish installing you will need to reboot and you will see the icon on you desktop. (it may vary according the options you installed)


After that you need to install the Fixpack 2. It is also using the same kind of installer using Netscape navigator and it is also very straightforward.

IBM OS/2 Developer's Toolkit version 4.5

I preferred to install the IBM OS/2 Developer's Toolkit version 4.5 from a installer created some time ago that included some patches. This package is key because it has the SOM compiler that we need for WPS Classes and the required SOM libraries.



Here it is a final view of some key elements of the config.sys paths and libpaths.


SET PATH=.....;H:\OS2TK45\som\common;H:\OS2TK45\som\bin;H:\OS2TK45\bin;H:\Netqos2;

SET DPATH=.....:H:\Ibmcxxo\Runtime;H:\Ibmcxxo\Runtime;H:\Ibmcxxo\Runtime;H:\OS2TK45\som\common\system;

SET INCLUDE=C:\usr\include\os2tk45\inc;C:\usr\include\os2tk45\gl;C:\usr\include\os2tk45;

SET LIB=C:\usr\lib;H:\OS2TK45\som\lib;H:\OS2TK45\lib;H:\OS2TK45\samples\mm\lib;

SET IPFC=H:\OS2TK45\ipfc
SET SOMRUNTIME=H:\OS2TK45\som\common
SET SMINCLUDE=H:\OS2TK45\h;H:\OS2TK45\idl;.;H:\OS2TK45\som\include;
Why some paths are not in the config.sys
I don't have some programs like icc.exe (IBM C Compiler) on the path because the "Command Line" icon on the previously installed "IBM C and C++ Compilers, Version 3.6.5" does a very good job loading the environment paths, so if it worked, I didn't see it necessary to change more the config.sys.

Compile Procedure

Checking the "make" file

The makefile is a text file that contains the instruction and procedure to compile the applications. Since there are several kind of make programs, sometimes it can change a lot from one to another. On this case, this makefile was created to be used with "nmake.exe".

Checking the makefile can understand a little bit about the procedure:

       @echo " Compile::SOM Compiler "
       sc.exe -C200000 -S200000 -sxc;xh;xih $<

       @echo " Assemble::Assembler "
       alp.exe -Mb +Fl -Li -Lr +Ls +Lm $(AFLAGS) $<
       @echo " Compile::C++ Compiler "
       icc.exe -Q -Sp2 -D__IBMC__ -W2 $(CFLAGS) -Gm -Gd -Ge- -G5 -C $<
       @echo " Compile::Resource Compiler "
       rc.exe -n -r $<

Here you can see the compiler calls to create the object and res files.

Later you can see the procedure to link the libraries, object files and create the DLL file.

hwman.dll: $(OBJS) $(RES) $(DEF)
       @echo " Link::Linker "
       -7 ilink.exe -nol -nobas $(LFLAGS) -dll -packc -packd -e:2 -m -o:$@ $(OBJS) $(LIBS) $(DEF)
       rc.exe -n -x2 $(RES) $@
       dllrname.exe $@ CPPOM30=OS2OM30 /n /q
       emxupd.exe $@ $(OS2_SHELL:CMD.EXE=DLL)

There are more details on the makefile that it may be good for you to check also.

Make Procedure

The way to start the compile process is to run the "Command line" of the development environment, change to the directory where you copied the source code and run "nmake".


The procedure will stop without errors


Remember that you can also log the output of the command in case you want to read the full text. You can do that by running:

nmake >out.txt

Take a moment to see the files that had been generated.


You can see that some .obj .res and .map files were generated and the most important file is hwman.dll which is the DLL that contains the compiled and linked WPS class application.

Lar's has also shared with me some other tips to run "nmake" on different ways:

  • "nmake" to do a normal build
  • "nmake "DEBUG=1"" to build with debug info
  • "nmake -a" to rebuild all
  • "nmake -a "DEBUG=1"" to rebuild all with debug info
