dyld: Library not loaded: /opt/local/lib/liblz4.1.dylib

When I run port upgrade outdated the two ports wants to update

The following ports will be rebuilt:
 llvm-9.0 @9.0.1
 gcc9 @9.2.0

With a result:

Failed to configure llvm-9.0: configure failure: command execution failed

You seem to be missing a library that should be provided by the lz4 port, which is a dependency of libarchive, which is a dependency of cmake.

[ryandesign (Ryan Carsten Schmidt)]

Right. So the solution is to sudo port install lz4. The only way I can see for this situation to have arisen is if you forcibly uninstalled lz4, bypassing the warning MacPorts printed letting you know that would break things; if so, then the breakage you are now encountering is to be expected.

Secondly, there is another message in the log:

sh: pkg-config: command not found

This appears to be a bug in the llvm-9.0 port for which I filed a separate ticket #60035.

I've installed macports from scratch and tried to install gcc9 at first and got this problem. I didn't uninstall anything.

Now I've installed lz4myself, thanks for suggestion

[jmroot (Joshua Root)]

I don't know how that would have been able to happen if installing from scratch; the dependencies are all correctly declared. If you can reproduce lz4 not being installed as a dependency of cmake, please reopen and show the log of that happening.

:debug:archivefetch Found Dependency: path: /opt/local/bin filename: cmake regex: ^cmake$

What does port provides /opt/local/bin/cmake say? I suspect that you didn't actually start from scratch, but had a number of files present in /opt/local that weren't registered with MacPorts.

[aliktab (Alik)]

You are right. I've deleted everything including opt/local and tried again with no errors. Thanks.
