internal compiler error: in convert_nontype_argument, at cp/pt.c:6827

[aejenk]

I dunno what I did wrong here, but for some reason, when I try to build polybar now I keep getting this error:

[  9%] Building CXX object bin/CMakeFiles/polybar.dir/components/bar.cpp.o

This happens both when xcb-proto was 1.12, and 1.11. xcb-randr is also at 1.11.1, but this error also popped up when it was 1.12.

[patrick96]

Can you give us some more info. What OS are you running (and what version) Which version of polybar are you trying to compile? Against HEAD or 3.0.5?

[aejenk]

@patrick96 I'm running Ubuntu Zesty, and I believe I'm trying to build v3.0.5, because that's the one I'm currently using, and I haven't upgraded it since then. I'm only trying to recompile it because of xcb-util-xrm, to make it compatible with pywal.

[patrick96]

You can figure out against which commit you are compiling by running

git describe --all --long

There are a few problems when compiling version 3.0.5 on Ubuntu 17.04. First gcc most likely won't work so you have to tell cmake to compile with clang like this:

cmake -DCMAKE_C_COMPILER="clang" -DCMAKE_CXX_COMPILER="clang++" ..

You also need to make sure that both packages xcb-proto and libxcb-randr0-dev are on the same version (preferrably 1.12). To make sure that is the case run

pkg-config --modversion xcb-randr 
pkg-config --modversion xcb-proto 

If you compiled with clang and have both xcb-randr and xcb-proto on 1.12 and it still doesn't work, please post the whole output of the cmake and make command

EDIT: Having both on version 1.11 should work too. See here for how to downgrade xcb-proto to 1.11

[aejenk]

here's the version of the commit : tags/3.0.5-0-g4e2e2a7

Also, libxcb-randr0-dev is on 1.11.1, while xcb-proto is on 1.11, does that mean they're on the same versions, or should I just upgrade to 1.12?

I was compiling using the build.sh script, so I'm not used to cmake, however I went into the polybar/build directory and ran the command you gave me, but it returned another error which was this...

I tried installing clang-3.8 on it, and it still showed that error. The output of make was the same as in the original post too.

[patrick96]

I think you should leave both at 1.11, I don't think there is a 1.12 version of libxcb-randr0-dev

You probably need the clang package which provides the latest clang version, then the cmake command should work

[aejenk]

Installed clang-4.0, which is the latest that I found, still ended up with problems. Here are all the commands that I ran, along with me showing that I have both clang-4.0 and clang++-4.0, just in case I'm either doing something wrong, or it'll help you out:

[textman@Tojopad420:~]$ cd polybar/build/

Oh, and I did managed to get a 1.12 version of xcb-randr by installing libxcb-1.12, however even with both of them at 1.12, the error popped up.

Should I remove the commit and download the latest version, just in case?

[patrick96]

The package you need is just called clang NOT clang-4.0, clang provides the /usr/bin/clang executable and will also pull in clang-4.0 as a dependency.

Where did you find libxcb-1.12? I don't see it in the repositories.

You can try to compile against the newest commit and see if that works.

[aejenk]

AH, I'm dumb. I'll give that a shot.

I also found libxcb-1.12 from this link : http://www.linuxfromscratch.org/blfs/view/svn/x/libxcb.html It worked well when I built it, it also linked to xcb-proto 1.12.

[aejenk]

Okay it worked well! Built with xcb-util-xrm support! Thanks!

[patrick96]

Great!

[coquizen]

As a note, patrick96's suggestion to sync up versions for xcb-proto and xcb-randr as well as using clang instead works on Debian Buster.
