Unable to build documentation [closed]
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.)
