Generate a lib and a DLL
I opened another DLL project to introduce the lib after introduction, what should call?
I am a c + + white to find more information or do not understand, you great god, beg to solve!

Or you can give me a direct call iLBC. Lib also tell me how to use!
The last 30 points, to solve!

CodePudding user response:

. Libraries (lib) is divided into two kinds, one kind is a dynamic library (DLL) import libraries, one is static library (including implementation), it seems that you use is the first,

Then in your Project, contains the lib library after the corresponding header file, put the lib files are added to the Project can directly use the functions (Project - & gt; Add to the project)

CodePudding user response:

# include "iLBC. H"
# pragma link "iLBC. Lib//with this line, is to tell the link, link to join iLBC. The lib, the lib files are added to the engineering effect is the same,

Doing so will report errors,

CodePudding user response:

I wonder why is it an error,
I have seen a information, said there is what might be the runtime compilation method caused by inconsistent,,

I also watch just now, the two are static library compile multi-threaded debugging MTD or error,,,

What is the meaning of such a mistake?

I now have a iLBC lib reference in an error, error content on the 6th floor!

But I always can't find the cause of the error!!!!! Check some information, also do not know how to solve this mistake!!

I quote the lib in the project properties (specifies the lib folder) also cited a code file, the error,

If I don't write this in your code # pragma co. Ilbc. Lib, he would have to find error function!

CodePudding user response:

Don't know what do you use the compiler,
C + + Builder of can directly Add
V, have to set up in what engineering properties,

C + + Builder also can

CodePudding user response:

The lib. If it is a different version of the BCB or other compilers compiled lib, had better use the current version CB recompiling.
Microsoft's LIB cannot directly in CB,nullnullnullnullnull
