Hi Elias,
I have changed ./configure to explicitly check for shm_open() rather than
for librt presence. SVN 328.

It's in libc on OSX. In other words, no special library is needed to

Hi Elias,
in which library is *shm_open()* contained under OSX?
It is *librt.so.1* in linux, but I can change *configure.ac
<http://configure.ac>* for OSX.

I found it. The problem is that shm_open is defined to -1:
#ifndef HAVE_LIBRT
# define shm_open(name, oflag, mode) (-1)
# define shm_unlink(name) (-1)
#endif
For some reason HAVE_LIBRT is not defined on OSX, but it does
have shm_open(). If I just remove this block, the resulting
binary works find on OSX.

Hi Elias,
as far as I remember, I haven't changed anything around the
shared memory.
Please check the permissions and the existence of the parents
of /dev/shm/apl-svars:

Since recently (the last few days?) I've bee getting this
error when starting GNU APL:
shm_open(/apl-svars) failed: No such file or directory

*** Failed to start APnnn: processor -1 will not accept
incoming shared variable offers. Expect surprises.
When looking at the code it looks like it's intentional.
