<h2>Known problems</h2>
|
|
<h4>Compiling</h4>
|
|
<ul>
|
|
<li>If your program is multi-threaded, make sure you defined macro <b><tt>_REENTRANT
|
|
</tt></b>to enable proper synchronization (if you are <i>using SGI
|
|
node allocator. If you are using new_alloc or malloc_alloc, you
|
|
won't need that)</i>.</li>
|
|
<li>You may encounter problems using <b><tt><iostream> </tt></b>in
|
|
mix with SGI STL <b><tt><string>, <stdexcept> </tt></b>without
|
|
defining <b>_STLP_USE_OWN_NAMESPACE.</b> Using <b>_STLP_USE_OWN_NAMESPACE
|
|
</b>is the most safe way to cooperate with new I/O<br>
|
|
library and is definitely recommended unless you recompile the whole
|
|
C++ std library with STLport installed.</li>
|
|
<li><b><tt>_STLP_USE_EXCEPTIONS</tt></b> is being defined
|
|
automatically if the compiler defined <b><tt>_CPPUNWIND</tt></b>
|
|
macro ("<b><tt>/GX</tt></b>" option). So you should not
|
|
worry about it.</li>
|
|
<li>There were reports that Visual C++ 4.0 have problems with
|
|
namespaces in certain cases. Due to that, <b><tt>_STLP_NO_NAMESPACES</tt></b>
|
|
defined for it in <b><stlcomp.h></b>.</li>
|
|
<li>You may encounter problems with too long symbols when compiling
|
|
with debug information. To handle this, try defining <b><tt>_STLP_USE_ABBREVS</tt></b>
|
|
in <tt>stlcomp.h</tt>.</li>
|
|
<li>You may experience problems with default SGI node allocator. I had
|
|
no such problems, though. Default node allocator is quite fast, so I
|
|
wouldn't recommend disabling it without serious reason. However, if
|
|
it causes problems, define <b><tt>_STLP_USE_MALLOC</tt></b> or <b><tt>_STLP_USE_NEWALLOC</tt></b>
|
|
to get bare malloc()-based or new()-based default allocator.</li>
|
|
<li>If your program is multi-threaded, make sure you defined macro <b><tt>_REENTRANT
|
|
</tt></b>to enable proper synchronization.</li>
|
|
<li><b>[ VC++ 4.2 and higher] </b>This version allows use of new-style
|
|
<b><iostream>, <string></b> with STLport , as well as
|
|
the old-style <iostream.h> . The default is new <iostream>
|
|
usage.</li>
|
|
<br>
|
|
If you want to use old-style <b><iostream.h></b> in your
|
|
project:
|
|
<ul>
|
|
<li>define macro <b>_STLP_NO_NEW_IOSTREAMS</b> in <b><stl_user_config.h></b>
|
|
or at the command line.</li>
|
|
</ul>
|
|
If you are going to use new-style <b><iostream></b> without
|
|
defining _STLP_USE_OWN_NAMESPACE:
|
|
<ul>
|
|
<li>You may have to edit relative (or set full) path to VC++
|
|
native headers<b><tt> </tt></b>in <stl_user_config.h>. Using
|
|
native versions is necessary to avoid clashes with compiled code
|
|
in C++ runtime library.</li>
|
|
<li>In the whole project, use coherent set of headers : <b>all
|
|
new-style.</b></li>
|
|
<br>
|
|
<b> </b>
|
|
</ul>
|
|
<li>You may also try <a href="http://www.sirius.com/~ouchida">SGI STL
|
|
adapted for MSVC++ 5.0 only,</a> by Wayne Ouchida. (Note : looks
|
|
like it's out of date and discontinued. It doesn't provide
|
|
debug support and other extensions of this adaptation).</li>
|
|
</ul>

|
<h2>Migration notes</h2>
|
|
You should experience no other problems migrating from VC++ STL to SGI
|
|
STL. Default <b><tt>allocator<T></tt></b> in this adaptation is
|
|
fully functional.
|
|

|
|
<h4>Versions prior to 4.0</h4>
|
|
Visual C++ older than 4.0 won't compile STL. You have to upgrade.
