Compiling KLayout on Debian 10 Buster

I've been trying to compile the current version of KLayout on Debian 10 Buster.
Sadly, I get stuck in a sort of compilation loop, which repeats itself.

I'd be grateful for any help, and have attached the repeating segment below:

  • Is the compilation really stuck or are there just a lot of these warnings? Compilation may take about one hour on a single CPU.

  • Hi Matthias, indeed i just got a lot of those warnings.
    Didn't know compilation would take so long. Thank you very much for your help.

  • Sorry to bother again. Once the compile is finished I end up with the binary files in "bin-release".
    I can't execute the "klayout" file from bash, is that correct?
    How do I proceed with the binaries? I didn't find any info on github or the build instructions how to get to an executable program, and somehow always assumed the binaries would be executable...

    Sorry for the rookie questions.

  • Hi,

    Not a rookie question in my opinion :smile: . It is not always that easy to find out how to do it, since there are usually multiple different ways to do it with any projects.

    Maybe I can show you how I do it:

    First obviously git clone the repository.

    Then do the following in the repository folder:

    sudo ./build.sh -j$(nproc) -prefix /usr/local/klayout -python /usr/bin/python3
    cd build-release/
    sudo make install
    sudo ln -s /usr/local/bin/klayout /usr/local/klayout/klayout

    This will first build KLayout, build it ( with how many processors your machine has), and then install it to /usr/local/klayout (this is the make install part). /usr/local is the folder (at least in debian) where user compiled projects should reside. Then finally I install a symlink into the bin to make it directly accessible in any shell.

    I know that ideally library files would reside in /usr/local/lib/klayout and the binary in /usr/local/bin, but I haven't figured out how to separate them, yet. The ideal approach would be to build a .deb package, but I am a bit lost how to build one. Maybe Matthias can bring more insight to that, as I think he has a CI way to build it :tongue: .

    Best,
    Sebastian

    P.S. @Matthias , is the multiline code formatting different than in the old style? I had to use quote for it, as the preview would look horrible otherwise, at least in the preview.

  • Hi Sebastian, thanks for the quick reply, and the clear and detailed instructions.
    With your suggestions I was able to complete the install. Instead of creating a symbolic link I went for a normal .desktop file.

    Thanks again for the great support. I learned a lot in the process!

  • Very good :)

    Actually "-prefix" is very similar to what you need in autoconf too. As KLayout's build is qmake based I can't make good use of autoconf, hence the build script.

    Instead of using prefix you can also copy "bin-released" wherever you want and set "LD_LIBRARY_PATH" to point to it. This is how I run test builds. Recently the Linux people added a nice feature to allow RPATH to be set to a relative one. But I have not tried whether this will solve the binary path relocation problem once and for all.

    @Sebastian I'm not aware of changes in the Markdown processing. I have used fenced code blocks (https://github.github.com/gfm/#indented-code-blocks) before and it still works. Maybe indented code blocks don't work any more. Vanilla appears to be using php-markdown (https://github.com/michelf/php-markdown). So please see the documentation there.
