** Note: this is a build patch only; the software is still broken **
Microwindows is a windowing system that used to build and work on ELKS:
https://en.wikipedia.org/wiki/Microwindows
http://microwindows.org/
The documentation in the most "recent" versions (Microwindows hasn't
seen a release since 2011) indicates that all of the ELKS support has
been untested since version 0.86, and some of the ELKS-specific
configuration options have been hidden or removed.
The latest snapshot fails to build for ELKS and is basically useless to
us. However, since 0.86 was the last version indicated in the
documentation to be tested against ELKS, I decided to grab 0.87 and see
if it could still be done.
This patch will convert a stock Microwindows 0.87 source tree to build
with ELKS and changes default options to be geared towards ELKS. You
must invoke 'make' with an ELKSDIR variable which points to your ELKS
repository source code directory (NOT to the kernel source, but to the
directory containing it!)
Get Microwindows 0.87 at:
ftp://microwindows.censoft.com/pub/microwindows/Historic/microwindows-0.87.tar.gz
Basic directions:
tar -xzf microwindows-0.87.tar.gz
cd microwin
patch -p1 < ../0001-microwin-087-elks-build.patch
cd src
make ELKSDIR=/path/to/elks/repo
The demo/test binaries will be in "microwin/src/bin". In my testing,
these binaries do NOT currently work under ELKS, but they compile and
most of them execute when copied to a "full3" image. If someone wants to
try it out and figure out how to make it actually work, go for it!
