Opencv3.2 text module build failed in macOS10.12

[logic1988]

I have encountered the following problems: /Users/logic/Desktop/opencv_contrib/modules/text/src/precomp.hpp:51:10: 'tesseract/baseapi.h' file not found The cmake file seems no path configuration for tesseract. Manually add tesseract search path, the problem solved.

Please add failed command line. For "makefile" generator you can use make VERBOSE=1 command.

I tried to build opencv on my mac(sierra:10.12) the cmaker command like this:

cmake -D CMAKE_BUILD_TYPE=RELEASE \ -D CMAKE_INSTALL_PREFIX=/usr/local \ -D OPENCV_EXTRA_MODULES_PATH=/Users/.../opencv_contrib/modules \ -D PYTHON2_LIBRARY=/System/Library/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib \ -D PYTHON2_INCLUDE_DIR=/System/Library/Frameworks/Python.framework/Versions/2.7/lib \ -D PYTHON2_EXECUTABLE=$VIRTUAL_ENV/bin/python \ -D BUILD_opencv_python2=ON \ -D BUILD_opencv_python3=OFF \ -D INSTALL_PYTHON_EXAMPLES=ON \ -D INSTALL_C_EXAMPLES=OFF \ -D BUILD_EXAMPLES=ON ..

and when i tried make -j4 ,it would report this error when the process scrolled to [62%]

In file included from /Users/.../opencv_contrib/modules/text/src/ocr_beamsearch_decoder.cpp:43: /Users/.../opencv_contrib/modules/text/src/precomp.hpp:51:10: fatal error: 'tesseract/baseapi.h' file not found

both opencv and opencv_contrib(7238cd2) are master branch

this is my tesseract version:

tesseract 3.04.01 leptonica-1.74 libjpeg 8d : libpng 1.6.27 : libtiff 4.0.7 : zlib 1.2.8

@karterotte Try to add -DENABLE_PRECOMPILED_HEADERS=OFF CMake option. Or disable "text" module via -DBUILD_opencv_text=OFF.

[karterotte]

thanks. It works!

[timotheecour]

@alalek adding -DENABLE_PRECOMPILED_HEADERS=OFF didn't work -DBUILD_opencv_text=OFF did work but obviously not a good solution

@karterotte Try to add -DENABLE_PRECOMPILED_HEADERS=OFF CMake option. Or disable test module via -DBUILD_opencv_text=OFF.

set opencv_text off,thx

[wu-yy]

also, I add -DENABLE_PRECOMPILED_HEADERS=OFF \ -DBUILD_opencv_text=OFF when cmake. It works!

Did the above:

cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules \
    -D PYTHON3_LIBRARY=`python -c 'import subprocess ; import sys ; s = subprocess.check_output("python-config --configdir", shell=True).decode("utf-8").strip() ; (M, m) = sys.version_info[:2] ; print("{}/libpython{}.{}.dylib".format(s, M, m))'` \
    -D PYTHON3_INCLUDE_DIR=`python -c 'import distutils.sysconfig as s; print(s.get_python_inc())'` \
    -D PYTHON3_EXECUTABLE=$VIRTUAL_ENV/bin/python \
    -D BUILD_opencv_python2=OFF \
    -D BUILD_opencv_python3=ON \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D INSTALL_C_EXAMPLES=OFF \
    -D OPENCV_ENABLE_NONFREE=ON \
    -D BUILD_EXAMPLES=ON \
    -D ENABLE_PRECOMPILED_HEADERS=OFF \
    -D BUILD_opencv_text=OFF ..

But now fails at 86%: [ 86%] Linking CXX executable ../../bin/example_tutorial_core_various [ 86%] Built target example_tutorial_core_various make: *** [all] Error 2

As per https://github.com/opencv/opencv_contrib/pull/2056#issuecomment-476005674, this turned out to have already been fixed in master and 3.4. So this issue can be closed.
