gtest does not compile on Mavericks

[Lenskiy]

gtest produces the following error during compilation on OSX 10.9

In file included from src/gtest-all.cc:39:
In file included from ./include/gtest/gtest.h:57:
In file included from ./include/gtest/internal/gtest-internal.h:40:
./include/gtest/internal/gtest-port.h:460:10: fatal error: 'tr1/tuple' file not found
#include <tr1/tuple>  // NOLINT

to make it compile the follow flag should be set up.
CPPFLAGS = -DGTEST_HAS_TR1_TUPLE=0

Ok, do you have a pull request by chance?

Long term we should really fix the way gtest is being provided on OS X. The recommendation is not to build it separately from your code you are testing, but rather have the gtest formulae provide the source files and have each project compile it in. For example, the Ubuntu package just installs a single source file.

How do I apply the CPPFLAGS to get brew to use them.

[enriquefernandez]

Apparently somebody patched the homebrew formula for gtest that already includes the TR1_TUPLE fix and other linking error fixes.

Doing

brew remove gtest
brew install gtest

and compiling again with the catkin_make_isolated command fixed these kind of errors for me.

@Lenskiy How to setup CPPFLAGS flag? I am getting the error.
