Hi guys,

I'm compiling the opencv with this command line:

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..

After a little, I got this error:

[ 3%] Building CXX object modules/core/CMakeFiles/opencv_core.dir/src/matmul.cpp.o make[2]: * No rule to make target /usr/lib/libz.so', needed bylib/libopencv_core.so.2.4.3'. Stop. make[1]: [modules/core/CMakeFiles/opencv_core.dir/all] Error 2 make: ** [all] Error 2

I'm using Ubuntu 64Bits with AMD processor.

Anyone could help?

Best!

Please provide output of your cmake command. It looks like problems with your system libz library. It looks like you have no permissions for it or it is placed in unexpected (not in /usr/lib) location.

I don't know why, ubuntu 12.10 has the /usr/lib files broken (libz.so for example) I deleted the symbolic link and did it again pointing to the correct file path and voilá!

Thanks to Alexander to give me the clue to solve this!

Where did you delete the symbolic link from? Where do we add the correct path?
