PostPosted: Sat Feb 23, 2019 5:18 pm    Post subject: [SOLVED] Compiling uTox & ebuild Reply with quote

Does anyone have any experience with compiling uTox? I tried the precompiled binaries provided but calling doesn't work without DBus installed and the file picker used is the GTK+3 one so I wanted to try to compile.
I followed the build instructions but I can't even get past the
Code:
cmake ..
part (what exactly is happening in that step?), CMake complains about missing libraries. What's odd is that I have all the dependencies installed, or at least all the required ones. First it was complaining about DBus, after that it's about filter_audio.

I quite frankly don't understand what's happening when you compile from source, what CMake does here, all I've ever done was
Code:
./configure
make
make install
Could anyone give me a hand, even if it's only general advice about compiling?

There used to be an ebuild in the main tree, maybe you can dig it up. I switched to qtox because this was causing OOMs during build with 2GB RAM.

Thanks for the tip, there's an ebuild in someone's overlay, turns out the CMake flags were -DENABLE_DBUS/FILTERAUDIO/TESTS=ON/OFF. Why was uTox dropped from the official repos? I suppose chances of getting it back are slim since not even the qTox ebuilds are actively maintained anymore.
It still seems to require GTK+3 file picker but I'll have to inquire the devs directly about that one. I'll mark this one solved.

Won't bump an already-solved thread so I'll just edit this in:
Found a solution for the GTK+ file picker change on the Web, just edit the src/xlib/gtk.c file like the patch says.
Unfortunately the file picker still wouldn't launch, I guess it was because it was trying to load "widget_set_margin_left" and "widget_set_margin_right" from the GTK+ lib, commenting out the lines mentioning it and recompiling did the trick.
The final patch is as follows:

OK, am I dumb or am I dumb? I've been trying to make myself an ebuild of uTox with no success.

The build instructions say you need to create directory "build" and that's where you run cmake & make, while I also need to apply a patch to a file in the root(?) unpacked directory (see above post with the patch). Needless to say I've no clue what I'm doing, the official ebuild docs haven't been much help to me and I would like some help, please and thank you. :)

It's complaining about missing the source directory, which is true since the distfile extracts into "/tmp/portage/net-im/utox-0.17.0/work/uTox-0.17.0/" (note the capitalisation). How do I set the source dir to the correct one? Also, am I handling the whole "build" dir shenanigans correctly?
Thanks for all your feedback.

Code:
 *   The source directory '/tmp/portage/net-im/utox-0.17.0/work/utox-0.17.0' doesn't exist

This because when you untar archive directory is named uTox-0.17.0, the overwrite S variable with
Code:
S="${WORKDIR}/uTox-${PV}"

That's what I was trying to do in the unpack phase using hilariously wrong syntax :D Thanks for the correction.
Now onto the patch and building:
Code:
>>> Unpacking source...
>>> Unpacking utox-0.17.0.tar.gz to /tmp/portage/net-im/utox-0.17.0/work
>>> Source unpacked in /tmp/portage/net-im/utox-0.17.0/work
>>> Preparing source in /tmp/portage/net-im/utox-0.17.0/work/uTox-0.17.0 ...
 * Applying utox-0.17.0.allow-gtk2.patch ...
The text leading up to this was:

The file I'm trying to patch is "/tmp/portage/net-im/utox-0.17.0/work/uTox-0.17.0/src/xlib/gtk.c" and it does exist after unpacking. The only thing I can think of is I'm using relative paths and I'm in the wrong directory but I assumed I would be in the source directory, therefore the path "src/xlib/gtk.c" should work. Thoughts?

Try

Code:
--- 1/src/xlib/gtk.c     2019-02-24 17:23:38.702737879 +0100
+++ 2/src/xlib/gtk.c     2019-02-24 17:15:52.507700317 +0100


IINM the first path gets stripped off.

Looking at the difference between gtk2 and gtk3 set_left_margin, there shouldn't be any.

Cheers, that worked.

I commented out the lines I did because of build failures saying something along the lines of the function not existing so I just assumed it was a new feature in GTK+3. It works like this but if you discover something new then do let me know.

I also realised that the uTox project doesn't actually provide usable release tarballs so I had to settle with their git repo (like they say in the compile instructions).
Here's my final working ebuild - it looks like it's nightly builds so i named it "utox-9999.ebuild":

If you're intrerested in testing it, feel free and let me know the results, preferably also on x86 if you can. Also keep in mind that filter_audio is not in the Gentoo repos so trying to turn the USE flag on is not going to work; I might try to put together an ebuild for that too at some point.

Yeah, on looking at it again, they changed things for widget spacing, names, etc. I don't have a good handle on converting gtk3 to gtk2 for the spacing.

But with your commenting them out, it should still work, it just doesn't pad the widget, ie. it might look a little funny.
