librsvg build failure: Symbol not found: __cg_jpeg_resync_to_restart

On macOS 10.14.6:

I'm at a loss here - what port is supposed to supply /opt/local/lib/libJPEG.dylib?

Cheers

UPDATE: uninstalling, then reinstalling libjpeg-turbo did not change anything.

ls -l /opt/local/lib/libjpeg* gives:

-rwxr-xr-x  1 root  admin  625212 Dec  4 19:17 libjpeg.8.2.2.dylib

According to nm, none of these libs provides a symbol cg_jpeg_resync_to_restart.

Replying to linolinco:

:info:build Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_graphics_librsvg/librsvg/work/librsvg-2.52.4" && /usr/bin/make -j4 -w all CFLAGS="-Os -pipe -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk -arch x86_64" LDFLAGS="-L/opt/local/lib -Wl,-headerpad_max_install_names -lobjc -Wl,-syslibroot,/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk -arch x86_64"

The actual relevant error message in the log is before this point, therefore, as always, please attach the main.log.

The libjpeg-turbo port (or the jpeg port, if you prefer) provides /opt/local/lib/libjpeg.dylib. No port provides /opt/local/lib/libJPEG.dylib. macOS provides /System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/libJPEG.dylib and some things in the OS link with that. Apple's libJPEG.dylib and MacPorts' libjpeg.dylib are not the same and are not interchangeable. For one thing, Apple's has __cg_jpeg_resync_to_restart and MacPorts' doesn't.

An error message about /opt/local/lib/libJPEG.dylib can only arise on systems with case-insensitive filesystems (whch is the default) and when the environment variable DYLD_LIBRARY_PATH has been set to /opt/local/lib. If you have that set in your environment, unset it. If it is the build system that is setting this, it must be changed not to do that. Let us wait and see what your main.log contains before we do further analysis.

So the actual cause appears to be:

:info:build dyld: Library not loaded: @rpath/libgobject-2.0.0.dylib
:info:build   Referenced from: /opt/local/lib/libcairo-gobject.2.dylib
:info:build   Reason: image not found

The relevant files in /opt/local/lib look okay:

-rwxr-xr-x  1 root  admin   382192 Jan  2 22:12 /opt/local/lib/libgobject-2.0.0.dylib
-rw-r--r--  1 root  admin  1226112 Jan  2 22:10 /opt/local/lib/libgobject-2.0.a
lrwxr-xr-x  1 root  admin       22 Jan  2 22:12 /opt/local/lib/libgobject-2.0.dylib -> libgobject-2.0.0.dylib

so the problem might be a misconfigured @rpath?

Given that libcairo-gobject.2.dylib is being provided by cairo, I'd start by forcibly uninstalling the latter (via sudo port -f uninstall cairo). Then reinstall it.

Let us know whether that makes a difference. If not, we can investigate further.

[linolinco]

Yes, reinstalling cairo solved the problem - thanks!

Great, glad the issue is resolved!
