The new binary (built on the current Linux) shows the
"miniature" fonts.
So, somehow, the fonts are available in the system, just not
for the new build.
Apparently the new build doesn't find the fonts or somehow
have access to them.
Is there a test I can do, or a build option to allow FLTK to
find the font resource?
I second everything Ian posted in his recent reply, please read this
first and follow his instructions to install the prerequisites.
The "simple" instructions below should get you going,
but if you'd like to use CMake to build FLTK and your own
application(s) please see advice at the end of this post. Note that
it's important to build *and* test FLTK (i.e. try the
provided test and demo programs) before you start building your own
projects. I suggest the following approach:
Download a new snapshot of FLTK 1.4 (recommended) or the latest
release tarball (currently 1.3.9) from the FLTK website, expand it,
`cd` to the just expanded FLTK root dir, and then execute:
$ ./configure
This runs the configure script with all default options. Please
save the output somewhere so you can post it if the build
doesn't work. Now continue with:
$ make [-jN]
This builds FLTK with all default test and demo programs in the
'test' folder. Commandline switch '-jN' (w/o []) is optional and uses a
parallel build. Replace 'N' with the number of CPU cores you want to
use. If the build breaks with error messages, please post the error
messages. If there are some warnings, please ignore them for now.
Then type:
$ cd test
$ ./demo
This runs the main `demo` GUI program with a menu (3x3 buttons) you
can use to run all test programs. Alternatively you can run any of
the test programs directly, e.g. test/editor, test/unittests, etc..
If this all works as expected you're ready to try your own projects.
Congratulation!
However: If this still doesn't work as expected, please post the
configure log you saved in the beginning (see above). This should
give us a clue what's going awry. My suspicion is that you missed
Xft dev files and more in your previous attempts (as Ian wrote in
his post), but after installing all prerequisites it should work
well.
Side note: we recommend using CMake for building FLTK 1.4 but it
should also work well for 1.3.9. If you followed Ian's instructions
you did already install CMake. Then read the file README.CMake.txt
for instructions on how to build FLTK with CMake and how to use
CMake to build your own projects that use FLTK.
