Undefined reference errors on build.

[MathematicsUnicorn]

Hello,

After I cloned the repo and installed a few dependencies manually and the rest via (apt build-dep awesome) I try to run make and get this:

`

I opened another issue earlier about a different error which was resolved after tweaking around with the lua modules, don't think they are related. Any help is greatly appreciated.
Thank you

tweaking around with the lua modules

This may have resulted in mixing different versions of Lua and LGI.
What's the output of running cmake -B build -L in the project root?

Thanks for the fast response! It's much appreciated.

[sclu1034]

Oh, I just realized, this isn't the LGI step yet, just lgi-check.c.
Since you mentioned APT, I assume you're on a Debian-based system. Have you made sure to install both the Lua runtime and Lua headers packages?

You're likely missing the latter, which is named liblua${version}-dev, where ${version} is your current Lua version (e.g. 5.3).

[MathematicsUnicorn]

@sclu1034
Yes I'm on Ubuntu 20.10. I did a quick sudo apt install liblua${version}-dev I had liblua5.3, liblua5.2 and liblua50 already installed.
Again, thanks for the reply! Any other ideas?

[MathematicsUnicorn]

@sclu1034 So managed to make some progress but now I think I'm at the lgi step you mentioned. I get the error on make

The lgi check failed.

Awesome needs lgi to run.

Add AWESOME_IGNORE_LGI=1 to your environment to continue.

running lua -e 'print(package.cpath)' outputs:

lua -v is Lua 5.3.3 and whereis lua outputs:

Thanks again!

Yeah, this now looks you're missing LGI. It's lua-lgi in the repositories or luarocks install lgi.

[MathematicsUnicorn]

@sclu1034 Yes I saw that so I tried installing via luarocks, after multiple errors I just uninstalled and re-installed luarocks, installed lgi, tried to make awesome but got a "generating API documentation" error. I downgraded from lua 5.3 to 5.2 to work around the error but not I, again, get the "lgi not found" error when I try to make awesome, despite luarocks install lgi exiting succesfully. I am at a complete loss.

[Elv13]

tried to make awesome but got a "generating API documentation" error.

Do you have this error somewhere?

[MathematicsUnicorn]

Hi @Elv13

I upgraded again to lua 5.3.5 and re installed luarocks to see if I'll get the error again. Here it is:

[ 81%] Generating API documentation

Error: no suitable Lua interpreter found

Error: supported versions are: 5.2 5.1

make[3]: *** [CMakeFiles/ldoc.dir/build.make:290: doc/index.html] Error 1

make[1]: *** [Makefile:152: all] Error 2

make: *** [Makefile:15: cmake-build] Error 2

I saw the "Error: supported versions are: 5.2 5.1" line, that's why I downgraded my lua version. liblua.3-dev is also installed.

lua and luarocks are installed per the luarocks wiki.

lua -v --> Lua 5.3.5
luarocks --version --> /usr/local/bin/luarocks 3.3.1

whereis lua --> /usr/local/bin/lua /usr/local/lib/lua

whereis luarocks --> /usr/local/bin/luarocks /usr/local/etc/luarocks /usr/local/lib/luarocks

and the output for cmake -B build -L asked earlier, is:

Error: no suitable Lua interpreter found
Error: supported versions are: 5.2 5.1

That error doesn't look like it's generated by Awesome, at least to my knowledge. So my guess is that some part of the build process used Lua 5.2, while the rest tried to use 5.3. Due to the progress into the build process, my guess would be that LDoc is running 5.2, but I'm not sure.
And since I'm not running Ubuntu/Debian, I can't set things up to compare.

What I can offer is these commands that we use for our upcoming CI rework:

sudo apt-get install --no-install-recommends \
    asciidoctor \
    cmake \
    dbus-x11 \
    gettext \
    gir1.2-gtk-3.0 \
    gir1.2-pango-1.0 \
    git \
    libdbus-1-dev \
    libgirepository1.0-dev \
    libnotify-bin \
    libpango1.0-dev \
    libstartup-notification0-dev \
    libx11-xcb-dev \
    libxcb-cursor-dev \
    libxcb-icccm4-dev \
    libxcb-keysyms1-dev \
    libxcb-randr0-dev \
    libxcb-shape0-dev \
    libxcb-util0-dev \
    libxcb-xfixes0-dev \
    libxcb-xinerama0-dev \
    libxcb-xkb-dev \
    libxcb-xrm-dev \
    libxcb-xtest0-dev \
    libxdg-basedir-dev \
    libxkbcommon-dev \
    libxkbcommon-x11-dev \
    xutils-dev \
    liblua5.3-dev \
    lua5.3

luarocks install lgi
luarocks install ldoc

This might not be everything you need, since the CI offers some baseline dependencies, but it should cover the majority.

[MathematicsUnicorn]

@sclu1034 That did it! For whatever reason I had installed ldoc (and a few other things) by hand before finding out there was a build-dep. It seems that the version on the repos was oudated. I was also missing markdown. Thanks for your help, it's much appreciated.

[Elv13]

I will re-open this. I think some recent changes made this problem worst. Since many distro ships lua 5.4 and people are going to install lgi using luarocks more often, I think it is worth investing in the cmake files to be smarter.

[ShayAgros]

@Elv13 We have a check for lua5.4 in the cmake. What do you have in mind ?

[sclu1034]

@ShayAgros The issue is not that something was running with an unsupported version.
Instead, OP kept installing and removing various packages in different versions, until they ended up in a situation where their version of LDoc didn't match any of the installed Lua versions.

I assume the "smartness" that @Elv13 wants to add to the CMake files is to make sure that, in addition to the check for version support, everything runs on the same version and to provide an easy-to-understand error message if that's not the case.
