Unable to install gtest

[jslee02]

I tried to install gtest using Homebrew on Mac 10.9.2 but failed. Here is the error message:

brew install https://raw.github.com/dartsim/homebrew-dart/master/gtest.rb

Did I something wrong?

I have the same problem. CMake isn't correctly generating the makefile, it seems.
Here's my link to the commands necessary for diagnosis: https://gist.github.com/Number-42/8c326938168c84b47aeb

It is not recommended by google to install a pre-compiled copy of gtest, since it needs to use the same compiler flags as your code.

It is instead recommended to include the gtest source code in your project and compile it inline. We do this for gazebo.

I am running into same problem. I'm running with a very similar setup to Numbe-42, except running OS X 10.8.5 Snow Leopard.

I was grepping around in /Library/Caches/Homebrew/gtest-1.6.0/, and the resulting Makefile does not have an "install" directive. I noticed a file called install-data-local that has this in it:

echo "'make install' is dangerous and not supported. Instead, see README for how to integrate Google Test into your build system."

I think the gtest formulae can be installed manually, but as I said before in this thread, it is not recommended to use an installed version of gtest. In fact, the homebrew tool will ignore gtest dependencies (see blacklist.rb) specified by a formula. That's probably why brew install dart doesn't install gtest.

I can advise about the recommended way to do use gtest.

I tried to create gtest formulae manually but, as you said, couldn't with this error message gtest is blacklisted for creation. We should add in gtest source as Gazebo did, and remove gtest formulae in this repo, I think.

Resolved by dartsim/dart#315.

Thanks @scpeters !
