Hi Russtopia,

thank you for reporting this.

Seems like I incorrectly assumed that the presence of libxcb implied the
presence of its header file. Hopefully fixed in SVN 1715.

Details:

your config.log says:

conftest.cpp:139:10: fatal error: X11/Xlib-xcb.h: No such file or directory

which sets apl_X11 to 0 (= X11 not present). At the same time there
is apl_GTK3 = 1 (= GTK present).

The first link error occurred because the GTK related code should not have
been compiled. That should now be fixed in SVN 1715.

The subsequent errors were caused by adding -lX11. Even though -lX11.
fixed the undefined symbol XInitThreads, it did not fix the root cause of
the problem.

I hope that GNU APL will now compile and link on your box, but some
functionality ⎕GTK, ⎕PLOT etc. may be affected. A better approach would
be to provide the missing X11/Xlib-xcb.h. Probably in package libx11-xcb-dev.

Best Regards,
Jürgen

If I add '-lX11' to LIBS in src/Makefile after running ./configure, it gets a bit further but fails on a GTK symbol:
