'some odd form of rounding problem, in mmAlloc' error message

[Peter Teuben]

For some time an error message
'some odd form of rounding problem, in mmAlloc' error message'
has been creeping up,most notably on new Mac 64 bit machines. But I've
now seen it also on Linux 64 bit, and filed our usual bugzilla report here:

http://www.mmarray.org/bugzilla/show_bug.cgi?id=1053

I'm in the process of fixing up offending code, but the main reason is
that our address space on 64 bit can exceed 4GB, and that does not
fit in an integer (32 bits) anymore. Luckily fortran has gone with the
times and integer*8 will effectively solve this.

I expect the 2012 summerschool version of miriad to be fixed up for this,
which will be coming out in beta this month. The 2012 school is Jun 17-23,
a bit earlier than usual.

On another note, I've been told that MacOS10.7 (aka Lion) will run the
10.6 binary version of miriad just fine, even recompile library and tasks.

Hello

I have recently bought a new Mountain Lion iMac, and installed the latest (2013) version of Miriad through MacPorts. It seems to be working ok, no installation error messages, but when I run a script to reduce data which previously worked, I get an error message concerning rounding problems.

### Fatal Error [selfcal]:  Some odd form of rounding problem, in mmAlloc

It seems this is a problem that has been going on for a while, but I don't know if other people still get it.

Is there an easy solution for the time being? Thanks!

can you also try the one advertised on http://carma.astro.umd.edu/wiki/index.php/Miriad

in particular

ftp://ftp.astro.umd.edu/progs/carma/miriad_mac10.8.tar.gz

you will probably need to have the HPC compiler suite, not the Apple one (they don't
seem to do fortran).    This is the old-style build, and has fixed the 64bit problem
a while back.    If it still shows up in macports, I can't help you easily, as this is
not a supported install method yet.

Hi Peter,

Can you be more specific about what to download from HPC ,

and directions how to proceed with installing Miriad.

thanks,

Mel.

I could be, but that's all in the prereq. listed on the wiki.

I think the most relevant page is probably

Hello Peter

Thank you very much. I was trying to install from source, but the ready-to-go binary works beautifully.

Cheers
