Environment Setup

The following setups are required for building and packaging Sync Client on macOS:

  • XCode 13.2 (or later)
    • After installing XCode, you can start XCode once so that it automatically installs the rest of the components.
  • Qt 6.2
  • MacPorts
    • Modify /opt/local/etc/macports/macports.conf to add configuration universal_archs arm64 x86_64. Specifies the architecture on which MapPorts is compiled.
    • Modify /opt/local/etc/macports/variants.conf to add configuration +universal. MacPorts installs universal versions of all ports.
    • Install other dependencies: sudo port install autoconf automake pkgconfig libtool glib2 libevent vala openssl git jansson cmake libwebsockets.
  • Certificates
  • dropDMG
  • bash environments
    • add following lines to the ~/.bash_profile file:
      export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/opt/local/lib/pkgconfig:/usr/local/lib/pkgconfig
      export PATH=/opt/local/bin:/usr/local/bin:/opt/local/Library/Frameworks/Python.framework/Versions/3.10/bin:$PATH
      export LDFLAGS="-L/opt/local/lib -L/usr/local/lib"
      export CFLAGS="-I/opt/local/include -I/usr/local/include"
      export CPPFLAGS="-I/opt/local/include -I/usr/local/include"
      export LD_LIBRARY_PATH=/opt/lib:/usr/local/lib:/opt/local/lib/:/usr/local/lib/:$LD_LIBRARY_PATH
      export PATH=$QT_BASE/bin:$PATH
      export PKG_CONFIG_PATH=$QT_BASE/lib/pkgconfig:$PKG_CONFIG_PATH
      export NOTARIZE_APPLE_ID="Your notarize account"
      export NOTARIZE_PASSWORD="Your notarize password"
      export NOTARIZE_TEAM_ID="Your notarize team id"

Building Sync Client

Following directory structures are expected when building Sync Client:


The source code of these projects can be downloaded at,, and


Note: the building commands have been included in the packaging script, you can skip building commands while packaging.

To build libsearpc:

$ cd seafile-workspace/libsearpc/
$ ./
$ ./configure --disable-compile-demo --enable-compile-universal=yes
$ make
$ make install

To build seafile:

$ cd seafile-workspace/seafile/
$ ./
$ ./configure --disable-fuse --enable-compile-universal=yes
$ make
$ make install

To build seafile-client:

$ cd seafile-workspace/seafile-client/
$ cmake -GXcode -B. -S.
$ xcodebuild -target seafile-applet -configuration Release


  1. Update the CERT_ID in seafile-workspace/seafile/scripts/build/ to the ID of Developer ID Application.
  2. Run the packaging script: python3 --brand="" --version=1.0.0 --nostrip --universal
