testBox failure on i386 #67

quantizationbit · 2013-07-12T21:55:01Z

System Slackware 14.0, 32 bit, gcc 4.7.1

Compiles but "make check" fails into the testing of ImathTest. I'm trying to put together a full clean build/install of OpenEXR, CTL (1.5 rc) to utilize ultimately ctlrender command for some testing. I've removed prior builds and removed openexr 1.7.0 package which comes with Slackware by default.

Hmm - interesting ... let me hunt down 4.7.1 here and give it a spin.

Have you had luck with previous versions of OpenEXR and this compiler?

Not sure how I do that?

Should I put a print statement in testBox.cpp?

Could you replace testBox.cpp with the attached and run that, or
alternatively edit the code as follows?

peterhillman · 2013-07-15T05:29:26Z

Next test: could you see whether compiling with -ffloat-store prevents
the problem occurring?
You should be able to do this by doing a make clean, then something
likeexport CPPFLAGS=-ffloat-store or setenv CPPFLAGS -ffloat-store
before running configure and make check again)
If this does fix the problem, we should probably implement a workaround
in the test packages. It's less likely to be an issue in the library itself

(This will help to test Richard's theory that it might be an
overprecision issue caused by 80 bit floating point math)

iRi-E · 2013-07-17T06:04:00Z

Hi,

I experienced the same error, and confirmed the test suite succeeds if -ffloat-store flag is added.

Tested ilmbase 2.0.1 on Ubuntu 13.04

quantizationbit · 2013-07-17T11:27:24Z

Ok yes using -ffloat-store works. I set the flag as described and rebuilt IlmBase from clean and make check succeeds. Now to figure out why slackware 14 comes with IlmBase 1.0.2 and OpenExr 1.7.0 as a few general image tools like ImageMagick depend on that.

quantizationbit · 2013-07-17T17:01:10Z

Ok using -ffloat-store gets IlmBase completed and installed. I've continued using that setting (although seems non-optimal to avoid register math) with OpenEXR and get to a "-nan" error in it's check.

peterhillman · 2013-07-18T08:34:57Z

Thanks for that. I think I'll modify that test not to write
nans/infs to the test images.
For the time being you could comment out the TEST
testOptimizedInterleavePatterns in IlmImfTest/main.cpp: since the
optimisation branch is disabled, that test isn't particularly
useful. The fail is an issue with the test, not the library itself.
Also, I don't think it's necessary to compile your installed version
of the library with -ffloat-store: if you can get it to pass all the
tests with -ffloat-store, it's probably safe to rebuild without the
flag and install it.
We might need to come up with a 'overprecision safe' test for
float-based types for use in the test packages.On 18/07/13 05:01, quantizationbit

The ilmbase testsuite (not the openexr one) succeeds if only the two files testBoxAlgo.cpp and testBox.cpp are built with -fno-inline or -ffloat-store (either of theses gcc options does the trick).

cary-ilm · 2019-06-28T23:25:40Z

Looking into the OpenEXR issue backlog. Is this still an issue, or ok to close?

cary-ilm · 2019-07-18T15:42:37Z

Closing the issue for now, feel free to re-open or file a new issue if you need further help.
