nextcloud face recognition on centos7

Filed under: Linux — Tags: , , — admin @ 12:11 pm

The face recognition for the nextcloud into centos 7 need DLib and OpenBLAS.

The problem is that DLib require C++11 support and the centos 7 have older version of gcc the solution is to install

yum install centos-release-scl

yum install devtoolset-7

The path for the gcc is located /opt/rh/devtoolset-7/root/usr/bin/gcc

To build the DLib this command


Need to be replaced with

cmake -D CMAKE_C_COMPILER=/opt/rh/devtoolset-7/root/usr/bin/gcc -D CMAKE_CXX_COMPILER=/opt/rh/devtoolset-7/root/usr/bin/g++ -DBUILD_SHARED_LIBS=ON ..

Also to install the pdlib the ./configure need to be replaced with

PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig CC=/opt/rh/devtoolset-7/root/usr/bin/gcc CXX=/opt/rh/devtoolset-7/root/usr/bin/g++ ./configure
