[gentoo-dev] OpenCV 2.3.1a, and earlier CUDA vs GCC 4.4

[gentoo-dev] OpenCV 2.3.1a, and earlier CUDA vs GCC 4.4

[Radosław Smogura]

Hello,

In OpenCV 2.3.1a and 2.3.0 there is test for GCC 4.5, it looks like this test 
is wrong, it should be 

if [ "$(gcc-version)" >= "4.5" ]; then

but is
if [ "$(gcc-version)" > "4.4" ]; then

In particulary this removes support for CUDA when GCC 4.4.5 is used. I think 
CUDA should be removed only from 4.5, or warrning message should be changed.

Regards,
Radosław Smogura

Thanks for the report.  Could you file a bug on it?  bugs.gentoo.org

That's how Gentoo normally tracks such things (and actually, a lot of 
other non-bug stuff too).  It helps keep them around until the problem is 
looked into and fixed, where a message posted to the list is often read 
and forgotten about, if the package maintainer doesn't have time right 
then to look into it.  The list is more for discussion of various 
technical questions that might be hard, or where there's likely to be a 
difference of opinion that needs hashed out.

Thanks again. =:^)
