I have been trying to compile a rather large (Fortran) program
using the -O3 directive to do all optimizations. Under these
conditions the compilation fails with the error message:-
usplit: Error: cannot read/write ucodes from/to /tmp/ctmlua01046//
tmp/ctmsa01046: Error 0
(the message appears all on one line), together with the message:-
dks0dls0 out of space.
When compiled without optimization there are no errors, and the
compiled program works normally.
I am running this on a Personal Iris 4D20 with 12Mbytes of memory
and the usual 380 Mbyte disk. On the disk the /dev/root filesystem
has 10663 blocks available (out of 31050), and the /dev/usr filesystem
has 45401 blocks available (out of 482816), but I can probably get the
percent usage down to about 87% quite easily. The total size of the
ucode files (*.u) is 4768829 bytes, of which the largest file has
978588 bytes. (Each file consists of several smaller routines, and I
would prefer not to have to split them up). When compiled without
optimization the final exectuable file amounts to 1750460 bytes.
Can anybody help?? What am I doing wrong?? Any advice will
be much appreciated.
Thanks

I haven't found any comamnds that make big temp files that don't respect TMPDIR (or use . for temp files). -- Scott Henry <scotth@sgi.com> / Traveller on Dragon Wings Information Services, / Help!

When compiling files the linker uses /tmp as a temp storage location for sundry files needed in compiling. You can do a coule of things here: 1) increase the size of your root parition. Don't try this unless you know what you are doing 2) make /tmp a link to /usr/tmp. (Or to a tmp dir on a partition with more space 3) There should be a compiler directive (can't remember which one it is) to use a different directory for the tmp storage location Trev -- ______________________________________/Abandon all hope ye who enter Trevor Paquette ICBM:51'03"N/114'05"W | - Gate Keeper of Labyrinth [~] [~] uunet![utai,alberta]!calgary!paquette |All who enter are abandoned...| |^^^^| | paquette@cpsc.ucalgary.ca | - Survivor of Labyrinth |_|_/\_|_|

This means that you are running out of space on /dev/root for the tmp files created during the compilation/optimization process. >When compiled without optimization there are no errors, and the >compiled program works normally. The -O3 optimization level creates larger temporary files than -O2 optimization. ( At O3 there are more stages of optimization, more temp files are created, code is run through different optimizer programs, etc, etc, etc, see the Iris-4D Series Compiler Guide for more info ). >Can anybody help??
