maintaining fltk on linux from git since quite a bit and never had  problems.

Since rev number 8605 (62e39e5559acdad536418c35575985a9c55de801) make
fails with:

    make[2]: *** No rule to make target 'fast_slow.h', needed by 'fast_slow.o'.  Stop.
    make[2]: Leaving directory '/home/balducci/tmp/install-us-d/fltk-8591.d/fltk-8605/test'

Trying to fix that single missing rule, just exposes other similar
errors: so I'm now brutally disabling test in Makefile:

    diff -c ./Makefile.DISABLE_TEST ./Makefile
    *** ./Makefile.DISABLE_TEST Thu Oct 10 16:56:06 2019
    --- ./Makefile Thu Oct 10 16:56:06 2019
    *** 18,24 ****

      include makeinclude

    ! DIRS = $(IMAGEDIRS) src $(CAIRODIR) fluid test documentation

      all: makeinclude fltk-config
            for dir in $(DIRS); do\
    --- 18,24 ----

      include makeinclude

    ! DIRS = $(IMAGEDIRS) src $(CAIRODIR) fluid  documentation

      all: makeinclude fltk-config
            for dir in $(DIRS); do\

But I'd like to understand if I'm doing something wrong or there is a
problem in the software

Cloning from

Configuring with configure:


(didn't try to build with cmake)

thanks a lot for any hint

Thanks for the report, but this is not the proper place to ask questions about building FLTK. Please use our mailing list fltk.general (Google Groups) for asking questions:!forum/fltkgeneral

That said, the Git commit given in your post is from the 'master' branch (1.4.0), hence I changed the version to "1.4-current" (not 1.3.5).

I tried a fresh build with current Git 'master' and it worked without issues running these commands:

--- snip ---
make clean
./configure \
  --enable-threads \
  --enable-largefile \
  --enable-shared \
  --enable-xinerama \
  --enable-xft \
--- snip ---

I removed '--prefix' and '--libdir' from what you posted, but this shouldn't change the build behavior. Something else must be wrong with your build environment.

The error message "*** No rule to make target 'fast_slow.h', needed by 'fast_slow.o'" seems to indicate that something is wrong with fluid which would normally be built before building the test/ folder.

Please ask further questions in fltk.general as mentioned above. This STR will be closed soon.

General support is not available via the STR form. Please post to the FLTK forums and/or mailing lists for general support.

Closing now.
