macos update build vm

[Antoine Martin]

Use 10.14.x (Mojave)?
Require 10.?

Record steps to setup the dev env.

[Antoine Martin]

• enable ssh
• install xcode 11.2.1
• as per ​build gtk-osx, run ./gtk-osx-setup.sh
• verify we can use the shell:

  alias jhbuild="PATH=.new_local/bin:$PATH jhbuild";jhbuild shell
  

• add our jhbuildrc:

  cat > .config/jhbuildrc-custom <<EOF
  _gtk_osx_use_jhbuild_python = True
  setup_sdk(target="10.14", sdk_version="10.14", architectures=["x86_64"])
  os.environ["CC"] = "/usr/bin/gcc"
  os.environ["DYLD_LIBRARY_PATH"] = ""
  build_policy = "updated-deps"
  modules = ["meta-osx-xpra-deps"]
  moduleset="https://xpra.org/svn/Xpra/trunk/osx/jhbuild/xpra-gtk3.modules"
  #os.environ["SSL_CERT_FILE"] = "/Users/osx/gtk/inst/etc/ssl/cacert.pem"
  EOF
  

• run:

  jhbuild bootstrap-gtk-osx
  jhbuild update
  jhbuild build meta-gtk-osx-bootstrap meta-gtk-osx-gtk3
  cd $JHBUILD_PREFIX/bin; ln -sf python3 python
  jhbuild buildone -f libxml
  jhbuild build
  

• build xpra

Still TODO:

• fix some build errors:
  • pango error during tests (solved by nuking them from the Makefile)
  • pycairo: tries python2? wrong path?
  • pygobject3: wrong path?
  • gtk-mac-integration-python: python2?
  • gtk-mac-bundler: wrong path?
  • python-lzo: lzo was not build first? force it?
  • pyobjc-*: version 6.1 bump needed, error with sdk level detection?
  • orc 0.4.31 requires meson
  • libvorbis: error missing uint*_t (inttypes.h?)
  • twolame: wrong path, needs --disable-maintainer-mode, error building docs: man page (skip)
  • faac and faad: wrong path, needs autoreconf
  • flac: needs inttypes.h? (as per ticket:2383#comment:21)
  • gstreamer: cannot find g-ir-scanner python bits
• moduleset updates: #2385
• merge changes from upstream gtk-osx (backport to v3.0.x as needed), and send pull requests for some of our changes, ie:
• #2384 gstreamer 1.16
• copy and import developer keys for signing

[Antoine Martin]

Updates (too many to list - important ones only):

• r24601 pyobjc 6.1
• r24608 gstreamer 1.16.2
• r24614 pango 1.44.7, atk 2.32.0, gdk-pixbuf 2.36.12
• r24616 atk 2.34.1
• r24617 gdk-pixbuf 2.40.0

Remaining problems:

• latest pango fails to build: revert it?
• pycairo: tries to run commands with python2!, must run from source dir?
• gtk-mac-bundler: must run from source dir
• pyobjc errors are caused by the sdk path, change it to have the version number instead of the symlink:

  export SDKDIR=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk
  export SDKROOT=$SDKDIR
  

others fail to detect the "os_level" - I've hardcoded it in the build file to move on.

• vorbis add #include <stdint.h> to $JHBUILD_PREFIX/include/ogg/os_types.h
• bomutils: needs source dir
• scons tries to use python2
• serf: path issue? needs python2?

[Antoine Martin]

Needed to make python3 a symlink:

cd $JHBUILD_PREFIX/bin
ln -sf python3 python
ln -sf python3-config python-config

Rebuilt from scratch - building python3 early so we don't use the system one, doing libwebp early to avoid errors building libtiff 4.1:

jhbuild bootstrap-gtk-osx
jhbuild buildone -f openssl
jhbuild buildone -f python3
jhbuild buildone -f libwebp
jhbuild meta-gtk-osx-bootstrap meta-gtk-osx-gtk3

• error finding girscanner:

gobject-introspection builds against the wrong python3 and uses the system one!
Use:

PYTHON=$JHBUILD_PREFIX/bin/python3 jhbuild buildone -f gobject-introspection

Hit issues building pango:

• needs to link against fontconfig, tweaked the ninja build file to add it
• fontconfig required an older version of the freetype dylib?
• rebuilt both then:

  ../../../../gtk/source/pango-1.44.7/pango/pangocairo-fcfontmap.c:109:5: error: implicit declaration of function 'cairo_ft_font_options_substitute' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
  

• rebuilt cairo and then pycairo

• error building gtk3 versions 3.24.11 to 3.24.13:

    CC       gdkglobals-quartz.lo
  /Users/gtk3/gtk/source/gtk+-3.24.13/gdk/quartz/gdkdnd-quartz.c:24:10: fatal error: 'gdkquartz-gtk-only.h' file not found
  #include "gdkquartz-gtk-only.h"
  

• pyobjc (still todo)
• liborc:

  ERROR: Error in gtkdoc helper script:
  
  ERROR: ['gtkdoc-fixxref', '--module=orc', '--module-dir=html'] failed with status 1
  Traceback (most recent call last):
    File "/Users/macos/gtk/inst/bin/gtkdoc-fixxref", line 28, in <module>
      from gtkdoc import common, config, fixxref
    File "/Users/macos/gtk/inst/share/gtk-doc/python/gtkdoc/fixxref.py", line 28, in <module>
      from . import common, highlight
    File "/Users/macos/gtk/inst/share/gtk-doc/python/gtkdoc/highlight.py", line 28, in <module>
      from pygments import highlight
  ModuleNotFoundError: No module named 'pygments'
  

• on the older system, itstool moaned about libxml2 until I rebuilt libxml2 against python2:

  jhbuild buildone -f python2
  PYTHON=/Users/gtk3/gtk/inst/bin/python2 jhbuild buildone -f libxml2
  PYTHON=/Users/gtk3/gtk/inst/bin/python2 jhbuild buildone -f itstool
  

Despite a newer version of scons, we have to temporarily switch the symlinks to python2 to build serf...

There's a circular dependency between libtiff and libwebp..

[Antoine Martin]

Works well enough.

Some details in duplicate ticket #2422.

Regression spotted: #2680
