Gary -
Thanks for your work on this matter. However, when building
applications based on Microwindows, Greg has built the system in such a
way, that you simply need to link to the libraries available in the
/src/lib directory and the headers found in /src/include. In fact, you
would be best served if you ignored all of the complicated targets that
Microwindows has, and just narrow yourself down to something similar to
the following:
------------
MWBASEDIR = /foo/bar/microwin/src
MWLIBDIR = $(MWBASEDIR)/lib
MWINCDIR = $(MWBASEDIR)/include
foo.target: foo.o bar.o
$(CC) -o foo.target -I$(MWINCDIR) -L$(MWLIBDIR) foo.o bar.o -lnano-X
.PREFIX: .o .c
.o.c:
$(CC) -c -I$(MWINCDIR) $< -o $@
-------------
In fact, we build the FNLX and ViewML binaries in exactly this manner.
This has the advantage of being easier for other people to understand,
especially if you are writing code that will be open source.
In the near future, we hope to have a standardized installation process
for microwindows, which will place the libraries and headers in a
standard location (kind of like what X11 does), which will make this
process even easier, especially for novices. Stay tuned.
Happy hacking,
Jordan
