General cross-compile with autotools:
./configure CC=icc CXX=icpc LD=icc CXXLD=icpc CFLAGS=-mmic CXXFLAGS=-mmic --build=x86_64-unknown-linux-gnu --host=x86_64-k1om-linux
- Install on host first because we need the host binary to compile Caffe:
./configure
make -j8
sudo make install
- Cross-compile for Xeon Phi:
./configure --enable-shared --prefix=/mnt/ssd/kivan/xeon_phi/protobuf-2.5.0/build/ --host=x86_64-unknown-linux-gnu "--with-protoc=${PROTOC}" CXXFLAGS=-mmic LDFLAGS=-mmic CC=icc CXX=icpc
./configure --prefix=/mnt/ssd/kivan/xeon_phi/glog-0.3.3/build/ --host=x86_64-unknown-linux-gnu CXXFLAGS=-mmic LDFLAGS=-mmic CC=icc CXX=icpc
./configure CC=icc CXX=icpc FC=ifort CPP="icc -E" CXXCPP="icpc -E" CXXFLAGS=-mmic CFLAGS=-mmic FCFLAGS=-mmic --prefix=/mnt/ssd/kivan/xeon_phi/caffe/libs/hdf5/ --host=x86_64-unknown-linux-gnu
