Hi all,
A check out this morning is not compiling for me:
mich...@yosemite:~/Desktop/openmpi_ext/src$ make all
mkoctfile -c -I/usr/lib/openmpi/include -I/usr/lib/openmpi/include/openmpi
comm-util.cc
comm-util.cc: In function ‘ompi_communicator_t* do_get(const octave_value&)
[with T = int]’:

comm-util.cc: At global scope:

mich...@yosemite:~/Desktop/openmpi_ext/src$
Is that expected at the moment?
Cheers, Michael
