Compiling native code for Directed Rounding

Compile the native library in /resources.

On Ubuntu this is something like: gcc -shared -fPIC -I/usr/lib/jvm/java-7-openjdk-amd64/include/ -I/usr/lib/jvm/java-7-openjdk-amd64/include/linux/ -o libDirectedRounding.so ceres_DirectedRounding.c

On Mac: gcc -m64 -I/System/Library/Frameworks/JavaVM.framework/Headers -c ceres_DirectedRounding.c gcc -m64 -dynamiclib -o libDirectedRounding.jnilib ceres_DirectedRounding.o

Make sure the library is called libDirectedRounding.*

Compiling the quad-double interface

In order to use the type QuadDouble, you need to download and build this library. Compile the provided JNI interface (also in resources/) for your architecture.

To compile on Linux:

g++ -fPIC -I/usr/lib/jvm/java-7-openjdk-amd64/include/
  -I/usr/lib/jvm/java-7-openjdk-amd64/include/linux/ -I/home/edarulov/share/qd/include
  -c ceres_common_QuadDoubleInterface.cpp

g++ -shared -o libQuadDouble.so ceres_common_QuadDoubleInterface.o ~/share/qd/src/*.o
