[Discuss-gnuradio] MacOS 10.7.3 - mmap or shm_open is not available

[Steven]

I have managed to compile the latest git version on MacOS 10.7.3 by setting CC=gcc and CXX=g++.

The issue now is that most of the tests fail, the first being gr-core-test-all.

"gr-core-test-all" start time: Apr 08 17:00 BST

Output:

----------------------------------------------------------

Testing gr_vmcircbuf_createfilemapping_factory...

gr_vmcircbuf_createfilemapping: createfilemapping is not available

I thought because it was tripping up at 

  void *first_copy = shmat (shmid2, 0, 0);

  if (first_copy == (void *) -1){

    perror ("gr_vmcircbuf_sysv_shm: shmat (1)");

    shmctl (shmid_guard, IPC_RMID, 0);

    shmctl (shmid2, IPC_RMID, 0);

    shmctl (shmid1, IPC_RMID, 0);

    throw std::runtime_error ("gr_vmcircbuf_sysv_shm");

  }

That I should try increasing the OS shared memory allocations but this didn't seem to make any difference.

Does anyone have any pointers as to where I should be looking?

Thanks,

Steven.
