Simbody 3.5 fails to compile on 10.10

The previous version was working fine on my machines.

This may be the problem:

Fails on 10.9.5 also -- investigating.

I had installed it successfully in the past couple weeks, but now it's not working. Maybe something changed in homebrew?

[sherm1]

I'm trying a manual (non-homebrew) install to see if I can get more info.

[sherm1]

Fails on manual install too 😢 -- my fault, not homebrew's!

[scpeters]

I don't know how I installed it previously.

The code that isn't working is here. It first creates a symbolic link in the build directory that links to the installed location for the example binaries, then the INSTALL command attempts to copy that symbolic link into the appropriate place in the installation (using CMake's INSTALL DIRECTORY command). It is that copy that's failing.

I tried GitHub's "blame" feature to see when that code went in. It was added in 143dd1a9 on Dec 23, 2013 by ... er ... @scpeters!

Since this has been working for a long time, I wouldn't be surprised if this is a change in CMake's behavior. My Mac has CMake 3.1 installed.

The cmake formula was upgraded from 3.0.1 to 3.1 12 days ago. I'm guessing that is the source of this problem.

[sherm1]

I think I have a fix ...

[scpeters]

Fixed in simbody/simbody#321, released in simbody 3.5.1, and formula updated in c842564.

@kt10aan thanks for the bug report!

[kt10aan]

Thanks for the extremely fast fix!

There appears to be the wrong SHA1 has though in the updated formula:

fixed the sha1 in c601c22

Not sure how I had it wrong.

My fault -- it took me a couple of tries to get the 3.5.1 release done. I did it once and then deleted it and re-created it. I think you might have pointed at the first attempt.
