B.3.3.2 Compiling gawk for PC Operating Systems

gawk can be compiled for MS-DOS, Win32, and OS/2 using the GNU development tools from DJ Delorie (DJGPP; MS-DOS only) or Eberhard Mattes (EMX; MS-DOS, Win32 and OS/2). Microsoft Visual C/C++ can be used to build a Win32 version, and Microsoft C/C++ can be used to build 16-bit versions for MS-DOS and OS/2. The file `README_d/README.pc' in the gawk distribution contains additional notes, and `pc/Makefile' contains important information on compilation options.

To build gawk, copy the files in the `pc' directory (except for `ChangeLog') to the directory with the rest of the gawk sources. The `Makefile' contains a configuration section with comments and may need to be edited in order to work with your make utility.

The `Makefile' contains a number of targets for building various MS-DOS, Win32, and OS/2 versions. A list of targets is printed if the make command is given without a target. As an example, to build gawk using the DJGPP tools, enter `make djgpp'.

Using make to run the standard tests and to install gawk requires additional Unix-like tools, including sh, sed, and cp. In order to run the tests, the `test/*.ok' files may need to be converted so that they have the usual DOS-style end-of-line markers. Most of the tests work properly with Stewartson's shell along with the companion utilities or appropriate GNU utilities. However, some editing of `test/Makefile' is required. It is recommended that you copy the file `pc/Makefile.tst' over the file `test/Makefile' as a replacement. Details can be found in `README_d/README.pc' and in the file `pc/Makefile.tst'.
