Type 'scons' to build and run all the available test cases.

It will automatically detect your platform and C compiler and

build appropriately.

You can modify the behavious using following options:
|
|
CC Name of C compiler
|
|
CXX Name of C++ compiler
|
|
CCFLAGS Flags to pass to the C compiler
|
|
CXXFLAGS Flags to pass to the C++ compiler
|
|
|

For example, for a clang build, use:
|
|
scons CC=clang CXX=clang++
