Error Building Cogutils on OS X 10.10.5 about cogutil HOT 7 CLOSED

Based on the warnings and error, I'm guessing you need to get a more modern compiler. Significant parts of opencog assume the c++11 standard from 2011, and parts of it might even be using the 2014 standard, not sure.

Since the compiler is clang, and clang is fairly up-to-date, I'm guessing that maybe you need to either specify some extra compiler flag to clang, or you simply have an old version of clang (llvm)

There some apple stuff here:
https://github.com/opencog/cogutils/blob/master/CMakeLists.txt#L64
but that assumes GCC:
https://github.com/opencog/cogutils/blob/master/CMakeLists.txt#L57

so I guess a IF(COMPILER is CLANG) stanzas are needed.

So, perhaps ‘clang -3.7’?

Go to google, and type in: "clang c++11 support" you will get these links:

read them. They probably contain the answers that you are looking for.

Is this now resolved?

from cogutil.

If it is resolved, can you please supply an update to the docs/README.osx file that explains all the magic incantations that are needed?

from cogutil.

This may be relevant: I am adding clang to the cmake file as I noticed that there is no such condition in cogutils. It will be part of the fix for #32

For now it appears that only gcc has been specified for cogutils.

Additionally the compiler flags were set to c++0x and not c++11, which will be included in the pull request

from cogutil.

Closing, I assume that this is fixed.
