hi @tarjanm-movidius,

i've checked locally fbpager plus your patches ontop of it.

the whole build-system should be moved more towards what fluxbox is using: autogen.sh (see https://github.com/fluxbox/fluxbox/blob/master/autogen.sh) … which is then generating configure, Makefile.in and all the related tools. I would rather remove all which is generated by autogen.sh.

even with your patches I ran into to problems to build fbpager ontop of aarch64. I then used autogen.sh as the base and came until:

git status
HEAD detached at gh.tm/master
Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
	modified:   .gitignore
	deleted:    Makefile.in
	deleted:    aclocal.m4
	new file:   autogen.sh
	modified:   compile
	deleted:    config.guess
	deleted:    configure
	deleted:    depcomp
	deleted:    ltmain.sh
	deleted:    missing
	deleted:    src/FbTk/Makefile.in
	deleted:    src/Makefile.in

The rest of your changes look valid. If you want, rework the build-system stuff by even further reducing it "to the max" and then I ll merge the whole thing.

Hi Mathias,
Thank you, I'm perfectly happy with your changes, feel free to merge it. Left the build-system there for convenience, but a well automated autogen should be just as easy to use.
Feel free to merge & thanks again

@tarjanm-movidius then i ll cherry-pick the relevant changes from your branch and skip the build-part.

can't tell you "when" though.

thanks anyway!

@tarjanm-movidius ah, cool. I'll try your branch on the weekend. The delay was not intentionally, I am sorry about it.
