c++.stl.port - compile error at DbC

compiling this code with DMC841C with STLport, error occured:

}
^
foo.cpp(15) : Error: '=', ';' or ',' expected
Fatal error: too many errors
--- errorlevel 1

..why? and what should I do to compile?

There's a good reason for why this does not work -- the STLport code's 
header files have "__in" and "__out" as parameters all over the place. 
If you look in the stlport\stl\stl_dm.h header file, you'll find the 
#define's.

You're #include-ing <iostream>, which comes from STLport.

Honestly, I'm not sure whether to fix this because the STLport people 
aren't necessarily friendly to bug fixes and "__in" as a parameter to 
template methods makes perfectly good sense.

thanks a lot.

insertion of 

#undef __in
#undef __out
#undef __body

after #include, it works.

--- another problem ---
so I tried to build debug version on STLport:


 make -f dm.mak


Error on line 69: bad syntax for implicit rule, should be .frm.to:

.. why?

I thought about this solution this morning in the shower. Glad it works 
for you.

make -f dm.mak




Use smake. :-)

free DMC++ does NOT include smake...

I'm well aware that the free DMC++ doesn't include smake, and neither 
does it include the DLL runtime.

My question for you would be, "Why are you rebuilding STLport when I've 
already done it for you?" Or, "Why haven't you purchased the CD yet?"

STLport distribution stlport.zip doen NOT include DEBUG version lib.
(only stlp45dm_static.lib)

so, when I specified -D option to enable DbC, linker can not find
appropriate lib.

You must have downloaded the incorrect file. My recent port of the 4.6.2 
STLport is http://mordred.cs.ucla.edu/STLport_DMC/STLport-4.6.2.zip. You 
will find the debug versions of the library in that zipfile. Also, 
please make sure you read some of my notes and installation instructions 
http://mordred.cs.ucla.edu/STLport_DMC/

There are two different debug versions of the library. There's the 
-DDEBUG version and the -D_STLP_DEBUG version. Other people have 
reported problems with linking a -D_STLP_DEBUG program, so YMMV.

STLport 5.0 will fix the some of the `__' nonsense because Microsoft's Whidbey
compiler (8.0) uses the same __ variables as STLport - causing name conflicts.
In general `__' is reserved for compiler/OS internal variables, I would like to
know why STLport chose to name all their variables in such a manner.

So that they wouldn't clash with (a) users, (b) other compilers, or (c) 
coolness factor? Could have been a holdover from the HP and SGI code bases.

Actually, I don't think that it'd make a stylistic or compilation 
difference if they used double underscores or not. Like you deftly 
pointed out, double underscores are generally used by the compiler 
vendors for "special things."
