?

and therefore a Qt5 error?
Comment 3 Andreas K. Hüttel archtester gentoo-dev 2013-09-06 16:53:26 UTC
Is Qt5 installed on your system?
Comment 4 Bernd Buschinski 2013-09-06 17:29:21 UTC
Yes, on mine.
And getting the same exact error.

OK this may take some time to figure out.

patch to fix opencv build if Qt5(core) is installed

this patches fixes the opencv build for me if Qt5 is present.
NOTE: as current gentoo does not have a Qt5 concurrent package, opencv will never successfully detect Qt5

Then opencv tries to find Qt4, and cmake FindQt4.cmake uses find_program to find the bins. But as Qt5 was partically found and some vars already have values.
For example QT_MOC_EXECUTABLE.

And http://www.cmake.org/cmake/help/cmake2.6docs.html#command:find_program
says... 
"If the program is found the result is stored in the variable and the search will not be repeated unless the variable is cleared."

so MOC will still have the old(Qt5) value.


So just clear all(Qt4 relevant) bin vars before the Qt4 try.

opencv-2.4.6.1.ebuild-qt4-fix.patch

Alternatively, simply passing `-DWITH_QT=4` instead of `-DWITH_QT=ON` seemingly works as well.
Comment 8 Dennis Schridde 2014-01-24 23:06:38 UTC
Persists in media-libs/opencv-2.4.8
Comment 9 Andreas K. Hüttel archtester gentoo-dev 2014-01-24 23:58:25 UTC
Sync in a while, should be fixed.
Comment 10 Dennis Schridde 2014-01-25 12:32:32 UTC
(In reply to Andreas K. Hüttel from comment #9)
> Sync in a while, should be fixed.

Confirming: Fixed
