Hi,
I'm resurrecting this old thread just to summarize the final outcome
for people coming to it from archive searches.
The "clone" stack trace has nothing to do with the real cause of the
error: starting with version R2010b, the MatLab runtime fails instead
with an "out of memory" error.
Indeed, running "strace" on the compiled program shows that it is
trying to allocate 128GiB of memory, although the UML has a few GB of
total virtual memory, and of course fails:
...
mmap(NULL, 137438953472, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory)
brk(0x2000ac6000) = 0xaee000
mmap(NULL, 137439088640, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory)
mmap(NULL, 134217728, PROT_NONE,
MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE, -1, 0) = 0x4051c56000
munmap(0x4051c56000, 37396480) = 0
munmap(0x4058000000, 29712384) = 0
mprotect(0x4054000000, 135168, PROT_READ|PROT_WRITE) = 0
mmap(NULL, 137438953472, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory)
...
A request to MatLab support was closed with the statement:
I investigated further into this, but we could not get MATLAB to
run on the virtualized kernel provided by UML.
[...] MathWorks does not test or design the MATLAB products for
use with virtual operating systems, thus virtual operating systems
are not supported for use with the MATLAB products. However,
while this is unsupported, there may be other virtual environments
where MATLAB does work.
The latest version of the MatLab Compiler runtime that I've tried is
v715 (from MatLab R2011a); up to that version there is apparently no
way of running compiled MatLab programs in a UML virtual machine.
A big "thank you!" to Richard Weinberger for all his help in
investigating this issue off-line.
Best regards,
Riccardo
