Building MacOS Binaries

Setup

Install XCode and its command line tools.

If homebrew or macports are installed, either remove them completely or at least move them out of the way.
Having these package managers installed will interfere with the jhbuild build process. (example here)

Setup gtk-osx

Download the latest version of the gtk-osx setup script and run it:

git clone https://github.com/Xpra-org/gtk-osx-build
cd gtk-osx-build
sh gtk-osx-setup.sh

This will have installed jhbuild in ~/.new_local/bin, so let's add this to our $PATH:

export PATH=$PATH:~/.new_local/bin/

Configure `jhbuild` to use our modules

From the gtk-osx-build directory, run:

ln -sf "$(realpath .)/jhbuildrc-gtk-osx" ~/.config/jhbuildrc
ln -sf "$(realpath .)/jhbuildrc-custom" ~/.config/jhbuildrc-custom

Bootstrap:

jhbuild bootstrap-gtk-osx

Optional: install pandoc

Build all the libraries

First, make sure that all the modulesets will be using the same system libffi as the one used by Python, so run this command from a jhbuild shell:

cat > ${JHBUILD_PREFIX}/lib/pkgconfig/libffi.pc << EOF
prefix=$(xcrun --show-sdk-path)
libdir=\${prefix}/usr/lib
includedir=\${prefix}/usr/include/ffi

Name: libffi
Description: Library supporting Foreign Function Interfaces
Version: 3.4.6
Libs: -L\${libdir} -lffi
Cflags: -I\${includedir}
EOF

jhbuild update
jhbuild build

Build and Package Xpra

git clone https://github.com/Xpra-org/xpra
cd xpra/packaging/MacOS/
sh ./make-app.sh
sh ./make-DMG.sh
sh ./make-PKG.sh

Signing the resulting .app, DMG and PKG images requires setting up certificates.
