This document gives a quick description of the source tree layout. For more information about the project and build instructions see the GitHub wiki.
Open Watcom allows you to place the source tree almost anywhere (although
we recommend avoiding paths containing spaces). The root of the source
tree should be specified by the OWROOT
environment variable in setvars
(as described in Build
document). All relative paths in this document are
taken relative to OWROOT
location. Also this document uses the backslash
character as a path separator as is normal for DOS, Windows, and OS/2. Of
course on Linux systems a slash character should be used instead.
The directory layout is as follows:
bld
- The root of the build tree. Each project has a subdirectory under
bld. For example:
bld\cg -> code generator
bld\cc -> C compiler
bld\plusplus -> C++ compiler
(see projects.txt for details)
build
- Various files used by building tools. Of most interest are the
*.ctl files which are scripts for the builder tool (see below)
and make files (makeint et al.).
docs
- Here is everything related to documentation, sources and tools.
distrib
- Contains manifests and scripts for building binary distribution
packages.
contrib
- Third party source code which is not integral part of Open Watcom.
This directory contains especially several DOS extenders.
build\bin
- This is where all build tools created during phase one are placed.
rel
- This is default location where the software we actually ship gets
copied after it is built - it matches the directory structure of
our shipping Open Watcom C/C++/FORTRAN tools. You can install the
system by copying the rel directory to your host and then setting
several environment variables.
Note: the rel directory structure is created on the fly. The
location of rel tree can be changed by `OWRELROOT` environment
variable.
