| 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 behaviour using following options: |
| BUILDDIR Directory to build into (default "build") |
| 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 |
| LINK Name of linker (usually same as CC) |
| LINKFLAGS Flags to pass to linker |
| LINKLIBS Flags to pass to linker after object files |
| PROTOC Path to protoc binary |
| PROTOCFLAGS Arguments to pass protoc |
| NODEFARGS Do not add the default CCFLAGS |
| NOVALGRIND Do not use valgrind for memory checks |
| |
| For example, for a clang build, use: |
| scons CC=clang CXX=clang++ |
| ''') |
