Build Mrtrix3 in CentOS7
CentOS 7 comes with gcc 4.8.5 but MrTrix needs 4.9+, also it needs Qt-qtsvg
To do this, addition to the mrtrix install instruction:
yum install qt5-qtsvg qt5-qtsvg-devel qt5-qtbase-devel devtoolset-3-gcc.x86_64 devtoolset-3-gcc-c++.x86_64
export QTDIR=/usr/lib64/qt5;export PATH=/usr/lib64/qt5/bin/:$PATH; export CXX=/opt/rh/devtoolset-3/root/usr/bin/g++;
./configure
./build
Then you get it.
