Problems with Macs os m1 platform

[Marcin81]

1. Should add spoved to dependencies into shards.yml

dependencies:
  qt5:
    github: Papierkorb/qt5.cr
    branch: master
  spoved:
    github: spoved/spoved.cr

4. lib/bindgen/clang/find_clang.cr5.
   Variables have problems with llvm_version (command nod found) and also change should add llvm/bin into the PATH.

makefile_variables_content = <<-VARS
  CLANG_BINARY := #{clang}
  CLANG_INCLUDES := #{system_include_dirs.map { |x| "-I#{File.expand_path(x)}" }.join(' ')}
  CLANG_LIBS := #{get_lib_args(clang_libs + llvm_libs).join(' ')}

  LLVM_CONFIG_BINARY := #{llvm_config}
  # LLVM_VERSION_MAJOR := #{llvm_version.split(/\./).first}
  LLVM_VERSION_MAJOR := "14"
  # LLVM_VERSION := #{llvm_version}
  LLVM_VERSION := "14.0.6"
  LLVM_CXX_FLAGS := #{llvm_cxx_flags}
  LLVM_LD_FLAGS := #{llvm_ld_flags}
  LLVM_LIBS := #{get_lib_args(llvm_libs).join(" ")}
  VARS
write_if_changed(makefile_variables, makefile_variables_content)

5. Compilation problem with: lib/bindgen/clang/src/record_match_handler.cpp and lib/bindgen/clang/src/record_match_handler.cpp.

linę 92:

// if (typeInfo.AlignIsRequired) bitSize += typeInfo.Align; // was that - but method does not exist
if (typeInfo.isAlignRequired()) bitSize += typeInfo.Align; // switch to compile
	klass.byteSize = bitSize / 8;

5. Compilation problem with: lib/bindgen/clang/src/preprocessor_handler.cpp and lib/bindgen/clang/include/regex.hpp
   Does not find

#include <pcre.h>

but file exists:

export LDFLAGS="-L$HOMEBREW_PREFIX/opt/pcre/lib"
export CPPFLAGS="-I$HOMEBREW_PREFIX/opt/pcre/include"

7. No configuration for Mac OS => lib/qt5/support/generate_bindings.cr

configurations = [
#      OS       LIBC   ARCH      Qt   Patch   Clang target triplet      Ptr  Endian

  {"darwin", "unknown", "aarch64", "5.15", "0", "", 8, "little"}#  binding_darwin-unknown-aarch64-qt5.15
]

8. Failure generate bindings

There was a problem expanding macro 'macro_4450161088'

Code in lib/qt5/src/qt5/binding.cr:6:1

 6 | {% begin %}
     ^
Called macro defined in lib/qt5/src/qt5/binding.cr:6:1

 6 | {% begin %}

Which expanded to:

 > 1 | 
 > 2 |   
 > 3 |   require "./binding/binding_darwin-unknown-aarch64-qt5.15"
         ^
Error: can't find file './binding/binding_darwin-unknown-aarch64-qt5.15' relative to '/Users/marcin/Documents/crystal_projects/qt_sample/lib/qt5/src/qt5/binding.cr'

10. lib/qt5/config/find_paths.yml not support latest version (=14)

  LLVM_CONFIG_BINARY:
    kind: Executable
    optional: false
    try:
      - llvm-config
    version:
      min: "4"
      max: "14" # was 11
      variable: LLVM_VERSION
      command: "% --version"
      regex: "^([0-9]+)."
    error_message: Failed to find llvm version
