I'm using Arch Linux x64, as for the linux font paths problem, where should I put it? I've never really begun using dlangui, I've just been trying to build an empty project with it as its dependency.

And I don't really know how to access the stderr nor did I find any ui.log
Though this is the result of "dub run dlangui:tetris -v"

Vadim, could you check your email. I Have do not related with DLAGGUI question.

It looks like DUB suppresses stderr output.
You can try
    dub build dlangui:tetris --build=debug
then run it manually
    examples/tetris/bin/tetris
You will see log messages on console

As well, you can redirect them to file:
    examples/tetris/bin/tetris 2> ui.log
Then check ui.log


I've tested under Ubuntu/x64 only.
Probably, there is no DejaVuSans.ttf in
/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf
or it's located in different location under Arch.

If you provide paths to some .ttf fonts under Arch, I can prepare quick fix with such hardcoded paths.

The path to fonts in Archlinux is:
/usr/share/fonts/TTF/DejaVuSans.ttf

and running the example lead to a seg fault.
I ran the gdb(with ddd) on it and it points to
line 93 of /dlangui-0.1.15/src/widgets/controls.d

For Fedora Rawhide the path to the DejaVu typeface is /usr/share/fonts/dejavu/ with there being a multitude of TTF font files in that directory.

Ubuntu being a Debian system, the Debian files are in /usr/share/fonts/truetype/dejavu

Added two more font paths (temporary solution, will be replaced with libfontconfig based solution later).

/usr/share/fonts/TTF/DejaVuSans.ttf
/usr/share/fonts/dejavu/DejaVuSans.ttf

It crashes on null font reference - no fonts in font manager.
Try v0.1.16 - it should work on your system.

So you are going to use dlangui in win app?
Please let me know if you find any issues (better, file issue on github).
If some necessary widgets are missing, I can add them.
