Test failures with Intel compiler

edit

Hi,

I have three test failures with an unoptimized, debug build. One I suspect is because I don't have a video capture device attached (the last below), but I suspect the first two are numerical errors. Please could someone confirm?

Thanks,

Chris.

//Details:

Platform: x86_64

Compiler: Intel version 13.1.1.163

OpenCV Version: 2.4.5

Build command:

cmake -DCMAKE_VERBOSE_MAKEFILE=TRUE -DCMAKE_INSTALL_PREFIX=/home/chris/downloads/opencv-install -DCMAKE_CXX_FLAGS="-O0 -fp-model precise" -DCMAKE_C_FLAGS="-O0 -fp-model precise" -DCMAKE_BUILD_TYPE=Debug ../

i) Numerical error somewhere?

ii) Another numerical failure?

iii) And presumably the following failure is to be expected because there is no video capture device?
