All,
Could someone advise me on building CMake from source on OS X 10.10.5
(Yosemite)? At the bottom of this email is the tail of the output from the
following build script:
g++

I found
http://hamelot.co.uk/programming/osx-gcc-dispatch_block_t-has-not-been-declared-invalid-typedef/
which says this is due to that bit of syntax (I've never seen that
either) within /usr/include/dispatch/object.h being understood by clang
but not by gcc.
Other sources [1] seem to say that this bit of syntax is supported by
gcc as it used to be provided by Xcode.
I am guessing you are also using gcc without apple provided patches
(e.g. homebrew)?
