Hi,
i am using a third party static library (.lib) that wraps a class interface
around an old C-style dll. in the static library they use the STL for some
stuff i don't know about.
in my own code, i also use the STL, for basic_string for example.
at link time, i get a lot of errors like:
msvcprtd.lib(MS VCP71D.dll) : error LNK2005: "public: __thiscall
std::basic_stri ng<char,struct std::char_trait s<char>,class
std::allocator< char> >::~basic_strin g<char,struct
std::char_trait s<char>,class std::allocator< char> >(void)"
(??1?$basic_str ing@DU?$char_tr aits@D@std@@V?$ allocator@D@2@@ std@@QAE@XZ)
already defined in ErrorHandling.o bj
ErrorHandling.o bj is the object file for the source file that contains my
errorhandling code. There is some basic_string stuff in there.
i can work around this by using /FORCE:MULTIPLE but this looks inelegant and
also gives lots of warnings. another way is to set project C++ options for
using runtime libraries in a dll instead of static. this works but i guess
this will only work if i don't have to link against multiple statis libs
that use the same functionality.
is there a better way to handle this problem?
kind regards and happy newyear to all of you,
Bruno. 1 1102
Hello Bruno,
It is likely because your project uses the MSVC runtime library dynamically.
That is, it uses the DLL version of the MS runtime library.
Try changing your project options to using the static version of the MS
runtime lib.

Hi
I have read some mail on the dev mailing list about PEP 318 and find the new
Syntax really ugly.
def foo(x, y): pass
I call this foo(1, 2), this isn't really intuitive to me!
Also I don't like the brackets.

In libraries, there is public symbols and "not public" symbols

Hi
I have this peculiar situation. I have a library of utility classes,
which I use to compile a binary. I want to reimplement a method in
class. The class is only a collection of static methods.
So I copy the source and header files to another place, change the
include path so this location will precede the location of the headers
of the library, change the method (details after) and compile.

We have two separate DLLs that do not interact (directly, at least). One is
an MFC extension DLL that was built back in VC++ 6 days (but has been

DLLs specify 'Use MFC in a shared DLL'.
