static library linking error, undefined symbols

[cjm99999]

Getting undefined symbol link error with a 3rd party static library.  The .lib and .h are in the project. Library is suppose to be compiled with Visual Studio 2008 and they tell me it's pure C code and so compiled with the C compiler, not C++.  They tell me it was not compiled with any of the following switches, /J, /Zp, /Ge, /Gh, and /Gs. I just did a new install of LabWindows 2010, downloaded a couple day's ago so have the latest.  Any idea's?  I've done this before but with a much older version of LabWindows and it worked without any of these problems.

Thanks.

Hello,

Would you mind posting a screen shot of the exact error you are seeing?

Here's what I get.  The library is adapter.lib, it's header is adapter.h.  I do have adapter.h included in the .c files.  I have this project running under VS2008 and am just trying to port it over to LabWindows.  Now, my VS2008 project does have one C++ file so it is being compiled with thier C++ compiler.  That C++ file just did some network IO which I'm not doing under LabWindows. But as I said the company that supplied adapter.lib say's there is no C++ anywhere in it so I assume it should be pure C compatible.

I've included adapter.h also.  This .h file is the same for 32 and 64 bit windows as well as VxWorks.  I can't see anything in it that doesn't work right in this case.

Hello,

Thanks for the files.  I'm going to work to replicate this on my end and will let you know what I find!

Thanks!

The file adapter.h doesn't define the calling convention for the functions. If you have the default calling convention set to __cdecl, try setting it to __stdcall (in Options|Build Options...).
