Thread and Array linking problems Topic is solved

[rodrigod]

Hello,

i am building a DLL, that uses arrays and threads besides other wxwidgets function. i am using VC++ 6.0 and when I build it i get linker error lnk2001 for many array and thread functions. I am almost sure that the problem is that i am not linking the right libraries. I want to know, which are the wxwidgets libraries that define arrays and threads, and which windows libraries it depends on. I didnt know what information you need to help me, so please tell me what do you need me to post here.

Thanks

It doesn't say in the docs?

I didnt find anything, but it would be great if anyone could tell me where to find it. Because i already searched it and got nothing. It is really common for me to run into this kind of trouble, if anyone got any clues i'd apreciate.

thanks

Just go to the page for the class you want to check out, and look at the info at the top. Should show you that information; You can also check out the libraries list for those sort of things.

Thanks,

Now the problem is a little different, it is still a linker error. Now I get a LNK2005 for my wxobjarray class. Here are my errors

This is my declaration of my class:

Code: Select all

WX_DECLARE_EXPORTED_OBJARRAY(cAVMCOM *, ArraycAVMCOM);
#include <wx/arrimpl.cpp> 
WX_DEFINE_EXPORTED_OBJARRAY(ArraycAVMCOM);
extern ArraycAVMCOM arrpcAVMCOM;

In the cpp files that I use that variable i delcare it like this:
ArraycAVMCOM arrpcAVMCOM;

If anyone could shed some light for me i would apreciate.

Thanks
Bye

Hi,
you have not to define class instance in .h file, only to declare it.

.h

Code: Select all

WX_DECLARE_EXPORTED_OBJARRAY(cAVMCOM *, ArraycAVMCOM);
extern ArraycAVMCOM arrpcAVMCOM;

.cpp (only in one file)

Code: Select all

#include <wx/arrimpl.cpp>
WX_DEFINE_EXPORTED_OBJARRAY(ArraycAVMCOM);
ArraycAVMCOM arrpcAVMCOM;

Thanks for the fast and precise answer that handled my problem!!!
