To compile the
|
||||
|
||||
libs/tuple/test/*.cpp
|
||||
|
||||
files, you need to set include paths
|
||||
for boost.
|
||||
For example, in libs/tuple/test directory you would type (using g++):
|
||||
|
||||
g++ -I../../.. tuple_test_bench.cpp
|
||||
|
||||
If you want to use tuple_io, you need to compile and link src/tuple.cpp:
|
||||
|
||||
g++ -I../../.. ../src/tuple.cpp io_test.cpp
