I want to generate libopencv_java410.so for my project.
I reference to this link: https://docs.opencv.org/4.1.0/d7/d9f/tutorial_linux_install.html .
After I execute 'cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DBUILD_SHARED_LIBS=OFF ..', it seems ok.
And then I execute 'make', things go wrong on libprotobuf. The command line errors are:

I wonder why this happens. My cmake version is 3.14.3. My gcc version is 4.4.6 Thanks in advance.
