Problem to regenerate a specific qt5 binding

[Fulgurance]

Hello, I'm a Gentoo Linux user and today I tried to regenerate a specific qt5 bindings to try qt5 with crystal, but when the process started, it stopped and I had an error:

  Bindgen requires a full installation of Clang, its libraries and development
  headers.  Please install these first, and restart this script.
  You can also manually run 'cmake . && make' in clang/ for debugging this issue.

CMake Error at crystal.cmake:28 (message):
  You're missing the LLVM and/or Clang executables or development libraries.

  

  If you've installed the binaries in a non-standard location:

    1) Make sure that `llvm-config` or `llvm-config-*` is set with --llvm_config FILE or is in PATH. The first binary found which satisfies version will be used.
    2) In rare cases if clang++ isn't found or is incorrect, you can also specify it with --clang FILE.

  

  If your distro does not support static libraries like openSUSE then set env
  var BINDGEN_DYNAMIC=1.

  This will use .so instead of .a libraries during linking.

  

  If you are missing the packages, please install them:

    ArchLinux: pacman -S llvm clang gc libyaml
    Ubuntu: apt install clang-4.0 libclang-4.0-dev zlib1g-dev libncurses-dev libgc-dev llvm-4.0-dev libpcre3-dev
    CentOS: yum install crystal libyaml-devel gc-devel pcre-devel zlib-devel clang-devel
    openSUSE: zypper install llvm clang libyaml-devel gc-devel pcre-devel zlib-devel clang-devel ncurses-devel
    Mac OS: brew install crystal bdw-gc gmp libevent libxml2 libyaml llvm

I missed to install something ?

Heya,

I believe the error starts at the beginning where the parser can't be built due to:

error: calling a protected constructor of class 'clang::tooling::CommonOptionsParser'
        clang::tooling::CommonOptionsParser op(argc, argv, BindgenCategory);

So it doesn't look like you missed to install something.

I'll try reproducing it here and follow up with any news. Thanks for the report.

Heya,

1. Which version of Qt is this for?

2. There's a lot in your report. Did you try the basic thing first? This one:

sudo apt install qt5-default # (Installs dependencies)
git clone https://github.com/Papierkorb/qt5.cr
cd qt5.cr
shards
edit support/generate_bindings.cr  # Configure which versions you want to build, temporarily
crystal support/generate_bindings.cr

Hello,

If it helps, applying the change described here to bindgen/clang/src/bindgen.cpp fixed this for me: https://stackoverflow.com/questions/22577741/an-odd-bug-in-commonoptionsparser
