Re: abi-version.h missing when not using "make install" ken williams Mar 07, 2021  
  Thank you Albrecht!

FLTK 1.4 from Git  on Manjaro Linux with GCC 10.2.0

After reading the Readme files you mentioned here's what I tried:

cmake -D OPTION_ABI_VERSION:STRING=10401 -D 'CMAKE_BUILD_TYPE=Debug' ../..                      (as I have the tree like this: fltk-1.4/build/manjaro)
make

And the result is:
- the FL folder from the fltk-1.4 folder still doesn't have abi-version.h file but has all the other .h files
- the FL folder from fltk-1.4/build/manjaro/ has only the abi-version.h file

I was expecting all the .h files to be in fltk-1.4/build/manjaro/FL or I'm getting this completely wrong?
Thanks again for your patience!

Great!

Please tell us your FLTK version (1.3.x, 1.4 snapshot, Git download?),
build platform and compiler + version when you're asking for help, just
in case it matters.

Since you run 'cmake ..' and 'make' I assume you're using either
Linux/Unix or Windows with MinGW and friends.

That's true, abi-version.h is generated during the build process in your
build/FL directory.

Not only that. It copies everything needed which includes abi-version.h
from the build folder to the installation folder. Did you check if
abi-version.h was in your /usr/local/include/FL/ folder after installation?

See above. If you want to build your project directly with the FLTK
build folder (w/o installing it) you need to specify this build folder
in your compiler's "-I /path-to-fltk/build/" flag, for instance (or in
your CMake build files, see README files below).

Yep, it's not in the distribution tarballs, snapshot or in the Git
repository.

I suggest to read the README* files in the FLTK distribution, at least
those having something to do with your build, e.g. README.CMake.txt and
README.abi-version.txt. These names are from FLTK 1.4 (git), they may be
different in 1.3.x (w/o .txt suffix).
