I am trying to build master in a docker container, and every time without fail, it gets to a point in the build and fails. Here is the log of when it starts building: ``` Now type "make" to compile. make all-recursive make[1]: Entering directory '/git/xfce-test/xfce4-panel/src/xfce4-panel' Making all in libxfce4panel make[2]: Entering directory '/git/xfce-test/xfce4-panel/src/xfce4-panel/libxfce4panel' GEN libxfce4panel-enum-types.h GEN libxfce4panel-alias.h GEN libxfce4panel-aliasdef.c GEN libxfce4panel-enum-types.c GEN libxfce4panel-marshal.c INFO: Reading libxfce4panel-marshal.list...

Aborting... ``` It looks like it has something to do with `libxfce4util`, which was built earlier, but I've been unable to trace the cause. You can test it yourself by downloading the repo at: https://github.com/xfce-test/container-archlinux. The PKGBUILD files used to build all the packages are located in `xfce/db`. ### Running the container If you want to run the container, just run the `./app/scripts/build-xfce-test.sh` script from the root folder. Alternatively, open the docker file and comment out the part that says `RUN /container/scripts/install-xfce-packages.sh`, build the container using the above script, then start it using the start script `./app/scripts/start-xfce-test.sh`. Everything you need will be mounted at `/container` and `/git/xfce-test` folder.
