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++ |
