Emx

emx (Eberhard Mattes eXtender) is an environment for creating 32-bit programs for OS/2 and DOS with the GNU C compiler (GCC). The main design goal of emx is to simplify porting Unix software to OS/2 and DOS.

The package contains tools for creating 32-bit programs which run both under OS/2 2.0 (6.167 or later) and MS-DOS (using an included DOS extender).

Also native OS/2 programs, including Presentation Manager applications can be created.

Development Tools

The emx development system include:

• gas - GNU Assembler
• gasp - GNU Assembler Preprocessor
• gdb - GNU Debugger
• gcc - GNU C compiler
• gprof - BSD/GNU profiler
• ld - GNU linker
• GNU binary utilities: ar, nm, size, strip, objdump
• GNU documentation system: texinfo
