Inline::C with MSVC and linking external library

rem45acp has asked for the wisdom of the Perl Monks concerning the following question:

Hello, I would like to be able to link to and use some functions from a C library, using Inline::C. The C library was compiled with Microsoft's compiler, so therefore I'm stuck using MSVC instead of gcc/mingw. What I'm having trouble with is that the compile process somewhere deep down in Inline can't properly link to the library. The platform is Windows XP. To make things easier, I placed the include file and lib file in the same directory as the perl script. I am using Visual Studio's command prompt to help sort out some environment variables, and also added the paths of MSVC's include files and libs to environment variables. For some reason it can't link to the library. Perl script:
use Inline C => Config => LIBS => '-usbi2cio.lib', BUILD_NOISY => 1; use Inline C => << 'END_C'; #include <windows.h> #include "Usbi2cio.h" void greet() { HANDLE h = DAPI_OpenDeviceInstance("UsbI2cIo", 0); printf("Hello, world\n"); } END_C greet;
Output from Inline:

    Is your library really called: -usbi2cio.lib?

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.
      Yes, the file name is usbi2cio.lib. It is a driver for an I2C board. And according to the Inline::C documentation, the dash goes in front?

        No. That parameter is basically the command line switch for the compiler to link the named library, -l and then the library name:

        use Inline C => Config => LIBS => '-lyourlib';

        So, in your case, I would try

        use Inline C => Config => LIBS => '-lusbi2cio';
