Libsvm symlink broken

[jpfeuffer]

brew gist-logs <formula> link OR brew config AND brew doctor output

brew gist-logs libsvm
Error: No logs.

The installation succeeds but is just wrong.

Verification

• [X] My brew doctor output says Your system is ready to brew. and am still able to reproduce my issue.
• [X] I ran brew update and am still able to reproduce my issue.
• [X] I have resolved all warnings from brew doctor and that did not fix my problem.
• [X] I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

Make CMake find libsvm.dylib

What happened (include all command output)?

CMake fails since the libsvm.dylib symlink does not exist anymore.

What did you expect to happen?

${lib}/libsvm.dylib symlink to libsvm.4.dylib exists -> CMake configures correctly as before with any other libsvm versions.

I expected commit https://github.com/Homebrew/homebrew-core/commit/1bf1dd6893ee09497e15c93778b56762cd0922bf#diff-1c1780a294e768938584d4a187ea90c7069897b63849a915cb075019c3e60d3aR30 also to change the symlink to version 4

Step-by-step reproduction instructions (by running brew commands)

brew install libsvm
ls -la /opt/homebrew/Cellar/libsvm/3.35/lib

Thank you for the very quick fix!

I'm still seeing issues loading the library:

@poshul, please run brew update && brew reinstall libsvm, then try again.

@poshul, please run brew update && brew reinstall libsvm, then try again.

After doing that (actually since it's a new container, after running brew update && brew install libsvm), I still pull down d006681611a00c39f5d5c4f6e37cc7c5d42f269a120cc0e4aab1e98253c80f56 According to @jpfeuffer it looks like the install_name is not getting set right.

[jpfeuffer]

Yes, I have the feeling that the MachO install_name replacement should not have been removed in the fix: https://github.com/Homebrew/homebrew-core/commit/d5238a306cae3560c8b3e834de89e2e9497a89a3
