errors LNK2001 and LNK2019 with VS .net 2005

rangalo · May 10th, 2006, 03:07 AM

Hi All,

I have succeeded in compiling a massive project, originally from vc6 to VS .Net 2005.

Now, while linking I am having loads of linker errors with the above code.

LNK20019 and LNK2001. Giving error msg that some symbol is not found. Actually, the library with the symbol has been already compiled as dll.

I looked into the documentation. The errors may be caused by

1. use of Inline functions (2019, also sometimes 2001)

2. use of C Runtime LIbraries (2001)

I dont know how to solve this problem. Can anybody tell me what should I do to remove these errors ?

I know all the missing symbols are there and the libraries are my own, so I can also change the code of the libraries.

this is the buildlog of one of the projects in the solution.

I also attach the implementation of a small class which is referenced and the symbol (destructor of that class) is not found and results in the error.

I hope this helps you guys to guide me.
