ticables_get_model and ticables_get_port returning NULL

[jakebromberg]

I'm running tilp inside an Ubuntu VM on a Mac. This is my output.

The ticables_get_model(NULL) and ticables_get_port(NULL) traces are fine, despite their CRITICAL level. They just mean that these functions were passed a null pointer for the handle.

The real error is below: (tilp:3481): Gtk-WARNING **: 02:38:52.020: cannot open display:. TILP depends on a reachable X server which speaks X11. The easiest way to do that is to use the udev rules in https://github.com/debrouxl/tilibs/blob/master/libticables/trunk/CONFIG , which are mentioned by the upstream user-oriented build script https://github.com/debrouxl/tilp_and_gfm/blob/master/tilp/trunk/build/scripts/install_tilp.sh (but are not included in some distro packages), and run TILP as non-root user.
That's probably not what you're doing here, but if you need to launch TILP through a ssh session, then you need to pass the -X (X11 forwarding) option to ssh, all the way from a X11-capable host.

(just mentioning also that tilp works fine on mac and you don't need a Linux vm for it, in case you believed so. The same install script linked by Lionel should be working, or the cmake build)

Okay, I'm trying to install tilp on macOS. I'm running into the following error when I run install_tilp.sh:

configure.ac:53: error: possibly undefined macro: AC_PROG_INTLTOOL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.

I'm on Sequoia, by the way.

[debrouxl]

That's a typical error message on a computer missing intltool. install_tilp.sh lists it as a build dependency.

[jakebromberg]

I really appreciate your help so far. At this point I'm running into the following error:

...
checking for libglade-2.0 >= 2.5.0... no
configure: error: Package requirements (libglade-2.0 >= 2.5.0) were not met:

Package 'libglade-2.0' not found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables GLADE_CFLAGS
and GLADE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
> port installed | grep libglade
  libglade2 @2.6.4_8 (active)

[adriweb]

Is your port-installed libglade2 providing pkg-config files (.pc) that you could give their folder's path of to the PKG_CONFIG_PATH env var? If not, try populating the two manual ones directly as the error says...

But really you could just disable building gfm in the script, as you likely won't need it, and relies and libglade that has basically been deprecated and removed from most distros.

[debrouxl]

Exactly: either you need to find glade somehow, or you can just disable the line which triggers building gfm.

[debrouxl]

FTR, I've started porting GFM to GTK+Builder locally, which is the proper way to fix the issue (barring a rewrite using another UI toolkit, which is more work). I haven't yet published anything, as the port isn't functional yet.
