Lately, I have been contributing to opencv 3.4 branch. I am facing trouble building 3.4 branch locally, 4.2 is getting build successfully. Here is the status of my branches when I checkout master branch -
* master
remotes/origin/2.4
remotes/origin/3.4
remotes/origin/HEAD -> origin/master
remotes/origin/master
I am using following command to cmake-
cd ~/opencv
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=Release \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D INSTALL_C_EXAMPLES=OFF \
-D OPENCV_ENABLE_NONFREE=ON \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules \
-D PYTHON_EXECUTABLE=~/.virtualenvs/cv/bin/python \
-D BUILD_EXAMPLES=ON ..
when I try to build it on master branch it is successfully building but version 4.2.0 .I want to build 3.4 to test my changes made on child branch of 3.4 locally. I am getting the following error -

What should I do to build branch 3.4 so that I can work on child branch of 3.4 and build it to test locally.
