Good question... Must be a reason, but I can't figure it out. It would be very useful to have CV_32U available.

Just for reference, and in addition of the other answer: on my Opencv 3.1 install on Ubuntu, the file is located here (starting from the source directory):

./3rdparty/ippicv/unpack/ippicv_lnx/lib/intel64/libippicv.a

or, for 32 bits installs:

./3rdparty/ippicv/unpack/ippicv_lnx/lib/ia32/libippicv.a

Thanks, that's a clear answer, although it is to me contradictory with CMakeLists.txt:835, that states: "status("Build Documentation:" PDFLATEX_COMPILER THEN YES ELSE "YES (only HTML and without math expressions)")". As I have the latex compiler, I expected it to say "YES", thus my incomprehension. But maybe that was just something that was planned and that eventually didn't work. (I'm not very good with cmake)

I have successfully build Opencv2.4.4, with:

cmake -D CMAKE_BUILD_TYPE=RELEASE ..

Now, a couple of days later, I want to build documentation for offline reading. After rerunning cmake, I notice the following output:

-- 
--   Documentation:
--     Build Documentation:         NO
--     Sphinx:                      NO
--     PdfLaTeX compiler:           /usr/bin/pdflatex
--

I couldn't find anywhere a list of valid options for cmake, so I had a look inside the file CMakeLists.txt, where I notice that the corresponding option seems to be called BUILD_DOCS.

So I try again cmake:

cmake -D BUILD_DOCS=YES -D CMAKE_BUILD_TYPE=RELEASE ..

or even:

cmake -D BUILD_DOCS=ON -D CMAKE_BUILD_TYPE=RELEASE ..

But, no, the cmake output keeps saying it won't build doc. And funnily , it seems that this option should be enabled by default (line 154) :

OCV_OPTION(BUILD_DOCS "Create build rules for OpenCV Documentation" ON )

However, after checking indepth the Cmakelists.txt file (line 807), it seems that is is indeed possible to build html and pdf versions of doc ?

So my questions are:

• Is is possible to build doc without Sphinx ?
• If yes, how can I force cmake to generate the "doc" target ?

(And, yes, in the meanwhile I got the online pdf files, but the question remains.)

I just spend 10mn posting a lengthy answer to my own question, with links on relevant material, and when I click on the button, I just loose everything (because new users need to wait 2 days before answering their own question). I'm ok with the principle, AS LONG AS I CAN COPY MY ANSWER BEFORE IT GETS THROWN AWAY !!! Now its lost...

ok, seems that it is related to Eigen... But not necessarly installed with it!

I'm not sure this is the right place to report a build problem, so please tell me.

I have a build error with Opencv 2.4.4 (occured also with 2.4.2) with something related to Eigen (?). Cmake (2.8.7) runs fine, but make throws an error:

[..]/modules/contrib/src/rgbdodometry.cpp:65:47: fatal error: 
           unsupported/Eigen/MatrixFunctions: No such file or directory

Is this file related to Eigen in any way ? Or is it supposed to be part of Opencv release ? How can I solve this problem ? Can I build Opencv without the 'contrib' part ?
