Preface
|
||
|
|
|
||
|
|
One of the problems one is faced when deciding whether using STL or not is
|
||
|
|
the question of portability and reliability. It's not a rare case when
|
||
|
|
compiler begins to crash when template constructs get too complex. While
|
||
|
|
it's not possible to predict such effects on arbitrary code, it is often
|
||
|
|
useful to test basic STL compatibility of the compiler. That's what this
|
||
|
|
testsuite is for. It don't use too complex construct with STL items. But it
|
||
|
|
do instantiate about every item to see if it works properly.
|
||

Genesis
|
||
|
|
|
||
|
|
This testsuite is derived from Cygnus Solutions STL testsuite, which is
|
||
|
|
based on ObjectSpace STL examples. The changes that have been made mostly
|
||
|
|
involve restructuring. You can run a single short test for particular STL
|
||
|
|
construct , or try to compile them all and link to single executable. You
|
||
|
|
may also test if your compiler can handle extremely long source files by
|
||
|
|
compiling a single source including all others.
|
||
|
|
|
||
|
|

Platforms
|
||
|
|
|
||
|
|
Makefiles for gcc, SUNPro, Borland, Visual C++ compilers are provided with
|
||
|
|
the suite. Look for .mak files in the distribution. It should be not
|
||
|
|
difficult to adjust one of them to your compiler.
|
||
|
|
|
||
|
|
----------------------------------------------------------------------------
|
||
|
|
|
||
|
|
Trying it out
|
||
|
|
|
||
|
|
After unpacking, edit appropriate makefile to fit your compiler and include
|
||
|
|
directories . After you've done, try "make check". This target is output
|
||
|
|
(stl_test.out) of single executable containing all the tests. Compare it
|
||
|
|
with stl_test.exp output (or stl_test.rand.exp, see below).
|
||
|
|
There should be no differences. If some test fails
|
||
|
|
to compile, you may try "make test_name.out" to produce single test
|
||
|
|
executable and run it.
|
||
|
|
|
||
|
|
----------------------------------------------------------------------------
|
||
|
|
|
||
|
|
Expected differences
|
||
|
|
|
||
|
|
As many tests use pseudo-random generators, you may get differences
|
||
|
|
in test output.
|
||
|
|
Basically, there are 2 random generator scemes used :
|
||
|
|
via rand() function : expected result in stl_test.rand.exp
|
||
|
|
via lrand48() function : expected result in stl_test.exp.
|
||
|
|
|
||
|
|
System-dependent notices:
|
||
|
|
If you are using STLport on OS390 machine, you should compare with stl_test.ibm390.exp.
|
||
|
|
|
||
|
|
Linux libc uses different random generator which doesn't match any of the above. Be prepared.
|
||
|
|
|
||
|
|
map1_test : some compilers don't zero-initialize data when builtin-type default constructor called, thus you may see some garbage instead of 0 in the output.
