OpenCV can be built with libraw1394 and libdc1394, but the latest version still uses a slightly older libraw1394 (0.8.0) han the current one in portage (0.9.0), so I've disabled that. But everything else seems to be working well. I've locally assigned it to media-libs. All other details in ebuild. Reproducible: Always Steps to Reproduce:
Created attachment 43551 [details] OpenCV-0.9.6 ebuild
The opencv build fails if a newer version of libdc1394 is installed (I have it installed for another app). The configure script fails to check for this, and therefore fails. Here is a build that downloads a newer configure.in from the opencv cvs. It is ugly -- if anyone can fix it, please do.

Created attachment 48598 [details] opencv-cvs-0.01.ebuild This ebuild downloads and installs the current opencv cvs tree. The releases have some irritating bugs that are fixed in the cvs, so this may be useful to some. It may be useful to specify a particular revision to checkout, which I may add in the near future. Just a note, this ebuild has to go in a 'opencv-cvs' directory in portage, not 'opencv', as the previous ebuilds do.
I won't compile with linux26-headers, it needs linux-headers even if you are using a 2.6 kernel.
Created attachment 67843 [details] Dated CVS ebuild for OpenCV This ebuild will download the cvs version based on the trailing date. If 20050908 doesn't work for you, just change it to an older or more recent date.
Created attachment 67954 [details] Dated CVS ebuild for OpenCV (Fixed) Sorry -- there was a bug in the ECVS_CO_OPTS flags.
I just used Roman's CVS ebuild to put OpenCV on a fresh Gentoo install. I had to rename it opencv-cvs-20050916.ebuild to get a version that would compile against recent versions of ffmpeg. Of course, there are lots of changes in cvs since then, but that date at least gives something that compiles and installs. Thanks to Roman and everyone else for putting an ebuild together. Benedict

Created attachment 79193 [details] This is an ebuild for the opencv 0.9.7 I made this ebuild to install the opencv-0.9.7 on my gentoo and it works. But I try a lot of things before, with ffmpeg, libdc1394, v4l in use flag... So it's working for me but it may not for you try it and comment please.
I suggest an addition to portage with and hard masked status. Is it possible ?

This ebuild compiles the 0.9.9 release without any problems on amd64 using gcc 4.1.1 -- it looks like this release of the opencv codebase does not have the gcc problems exhibited by earlier releases. Please include opencv in the standard portage tree.
Noticed that this bug report doesn't contain a description of opencv for the manifest file. Please find an appropriate description below: OpenCV is a library aimt at real time computer vision applications. Some example application areas include Human-Computer Interaction (HCI); Object Identification, Segmentation and Recognition; Face Recognition; Gesture Recognition; Motion Tracking; Ego Motion, Motion Understanding; Structure From Motion (SFM); and Mobile Robotics. The library is intended for use, incorporation, and modification by researchers, commercial software developers, government and camera vendors as reflected in the license. (http://www.intel.com/technology/computing/opencv/license.htm)
I would suggest that opencv be placed in the media-libs category in portage.

To avoid a conflict between quicktime and xine, I ran the emerge as: USE="-xine" emerge opencv. I had to modify the 20061111 patch in order to conform to minor changes in the wording of the config.in file. The ebuild died again, requesting libtoolize --copy --force so I uncommented line 52 of the ebuild. That succeeded, but the ebuild died again during compilation of cvsmooth.cpp. I gave up...

sci@g.o: can we put the ebuild in the science overlay, or maybe on Sunrise?
(In reply to comment #34) > sci@g.o: can we put the ebuild in the science overlay, or maybe on Sunrise? Hi, I would be glad to do it, and probably in main tree soon. Thanks all for the contributions! Please mark the unused attachments as obsolete. If I assume Neil's last ebuild for 1.0.0 is the correct one, a quick look at it tells me it still needs some work. I have not tested it, but here is a brief list of possible changes: - HOMEPAGE: one is enough - syntax in DEPENDS: gtk2 whereas gtk in use flags, spaces - USE flags: twice ffmpeg, make sure all these use flags are really useful and you don't miss any. According to the install docs, there are at least some language bindings and image libraries. - patches in src_unpack instead of src_compile - *flags: are you sure all this filtering is necessary? - autoconf stuff: put in in src_patch, also use eautoreconf and friends, from autotools eclass - make sure testing works, e.g. by enabling FEATURES=test while emerging, otherwise, create a src_test (almost mandatory for scientific packages) - honour the docs/examples with a doc and/or examples flag if any, and do not dodoc COPYING, which will end up in the licenses directory anyway. - LICENSES: are you sure the intel license is bsd?

Created attachment 130219 [details, diff] Patch for opencv-1.0.0 to remove ffmpeg related compile errors. I've added a patch for the cvcap_ffmpeg.cpp file from opencv-1.0.0 which removes all ffmpeg related compile errors by changing img_convert to sws_scale calls and adding the previous patches. This enables opencv-1.0.0 to compile cleanly on my machine.

It builds fine, but sth seems to be wrong with ffmpeg: undefined symbol: sws_getContext (/usr/lib/libhighgui.so) undefined symbol: sws_scale (/usr/lib/libhighgui.so) this also occurs when building with USE="-ffmpeg" i have media-video/ffmpeg-0.4.9_p20070616-r2 installed here

good to know, but this build also gives me a undefined symbol: sws_getContext (/usr/lib/libhighgui.so undefined symbol: sws_scale (/usr/lib/libhighgui.so) on ldd -r :(

I added an ebuild for OpenCV to the tree as media-libs/opencv without noticing this bug. Sorry. I will take the lead on getting all the patches in this bug applied to my email. sci@ guys, do you want me to assign this bug to myself? Also, for an example app that uses OpenCV, check out dev-python/PyQrcodec, which can encode and decode QR codes, which are used to quickly open URIs on Japanese mobile phones.
Hi Josh, Indeed, Thomas work on the overlay is pretty much complete and avoid automagic. It will be nice if you could merge it with the one in the portage tree. Re-assigning. Thanks.
Hi, After fixing opencv up I'd like to continue to help out with this package. Could I be a secondary maintainer? It doesn't matter if it's through the science herd or not, but I'd like to keep my eye on this package.. :) Also Josh, I'll be sending my fixes upstream this week.
Fixed in CVS, opencv is in gentoo-x86!! :)
