mpv 0.34.1: Xcode is required even for the precompiled binary

[dardo82 (Michele Venturi)]

MPV needs Xcode, otherwise it prints an error:

dyld: Library not loaded: @rpath/libswiftAVFoundation.dylib
  Referenced from: /opt/local/bin/mpv
  Reason: image not found

All the missing libraries are available in /usr/lib/swift,
but LC_RPATH (checked with otool -l $(which mpv))
points only to /opt/local/lib and the Xcode directory.

Is this issue caused by the way the port is built
or should it be fixed upstream instead of here?

The OP is trying to install MPV on a machine that does not have Xcode installed. This should work because MPV is available from MacPorts as a binary archive.

OP, for the sake of completeness, are the Developer Command Line Tools installed?

BTW, it's pretty easy to add another search path to the rpath search paths.

Look up "-add_rpath" in the install_name_tool man page.

Then add one to where you have noted the libraries to be, using install_name_tool, to mpv

then you will get an idea how easy a fix may or may not be for MacPorts.

I have the CommandLineTools installed.


RPATH can be changed with command:
sudo install_name_tool -add_rpath /usr/lib/swift $(which mpv)

With the lib dir in RPATH I get this error:

dyld: Symbol not found: __T0So8NSWindowC5LevelV6AppKit01_cdD23NumericRawRepresentableAEWP
  Referenced from: /opt/local/bin/mpv
  Expected in: /usr/lib/swift/libswiftAppKit.dylib
 in /opt/local/bin/mpv
zsh: abort      mpv

that is similar to what is reported here:
​https://github.com/mpv-player/mpv/issues/9714


The libraries are from a support package:

pkgutil --file-info /usr/lib/swift/libswiftAppKit.dylib
volume: /
path: /usr/lib/swift/libswiftAppKit.dylib

pkgid: com.apple.pkg.SwiftRuntimeForCommandLineTools
pkg-version: 10.2.0.0.1.1552586384
install-time: 1645223925
uid: 0
gid: 0
mode: 755

that can be downloaded here from Apple:
​https://support.apple.com/kb/dl1998


The libraries in Xcode.app and /usr/lib/swift are different:

diff /usr/lib/swift/libswiftAppKit.dylib /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/libswiftAppKit.dylib
Binary files /usr/lib/swift/libswiftAppKit.dylib and /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/libswiftAppKit.dylib differ

I use Xcode 9.4.1 plus Swift 4.1.2 now.
Let me know if you need other details.

Does the issue still exists on High Sierra? For me on Monterey I can see RPATH includes /usr/lib/swift.

Hello , i am having similar issue on HighSierra?

Hello , the issue occurs with Xcode 10.1 on MacOS HighSierra, downgrading Xcode to 9.4.1 solves the issue.
