2d62dc5f16 moved some tests that require user interaction from tuple_test_bench.cpp
to another_tuple_test_bench.cpp


[SVN r11059]
2001-09-07 11:04:50 +00:00
2a2632a159 tuples in separate namespaces now compile under MSVC++ as well
changed tuple_length, tuple_element, tuple_access_traits
to tuples::length, tuples::element and tuples::access_traits


[SVN r11058]
2001-09-07 11:02:01 +00:00
b8cca277e5 Now works on non-MSVC compilers
[SVN r11057]
2001-09-06 22:25:15 +00:00
c10fd424bc Definitions now in tuples subnamespace
[SVN r11052]
2001-09-06 13:51:22 +00:00
984cbdc728 tuples subnamespace added
[SVN r11051]
2001-09-06 13:50:27 +00:00
09a730c9bc most definitions are now in tuples subnamespace, more tests moved
to tuple_test_bench.cpp

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
