Running neolink fails on Macos due to Library not loaded (libssl)

[ncul777]

Now I know this is more gstreamer issue rather than neolink but reporting for reference or if anyone has any ideas

Macos 14.3.1,

To Reproduce

1. Install gstream brew install gstreamer
2. Create config file (using the sample)
3. Run neolink

Actual Behaviour

./neolink rtsp --config=neolink.toml
dyld[26705]: Library not loaded: @rpath/libssl.1.1.dylib
  Referenced from: <C5A2BDA1-CBE4-3F5A-908B-6E20F731954C> /Users/nc/Downloads/neolink_macos/neolink
  Reason: tried: '/Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libssl.1.1.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libssl.1.1.dylib' (no such file), '/Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libssl.1.1.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libssl.1.1.dylib' (no such file), '/usr/local/lib/libssl.1.1.dylib' (no such file), '/usr/lib/libssl.1.1.dylib' (no such file, not in dyld cache)

Note gstreamer installed openssl v3

Doing the following didn't help

brew install openssl@1.1

Expected behavior Neolink to connect to the camera

Versions Neolink software: 0.6.3 mac Reolink camera model and firmware: Reolink Lumus

This is because brew install openssl@1.1 is keg only which means it is not installed into /usr/local/ but only kept in its keg directory (which macos dosent search)

You can fix this by telling macos where the binary is. There are a few ways to do this. But this is what works for me

cd /neolink/location/whereever/you/put/it
install_name_tool -change @rpath/libssl.1.1.dylib /usr/local/opt/openssl@1.1/lib/libssl.1.1.dylib neolink

Which will edit the neolink binary to swap the path from @rpath/libssl.1.1.dylib to /usr/local/opt/openssl@1.1/lib/libssl.1.1.dylib which is where brew installs the keg

Ok so I have a build of this with updated rpath, this should be addressed it in future releases

[ncul777]

Thanks a lot for investigating.

I updated that but ran into similar with libcrypto dyld[16317]: Library not loaded: @rpath/libcrypto.1.1.dylib

I only seem to have libcrypto.3.dylib in /usr/local/lib so

I then uninstalled via brew and downloaded/installed the macos pkg from gstreamer site as recommeded in the installation instructions

Neolink now runs and connects to camera!

There is a gstreamer warning on startup which didn't seem have an impact on capturing images (using the command ./neolink image --config=neolink.toml --file-path=output.jpeg Lumus)

I'm happy to close this issue.
