I have created LIB1.DLL library in MSVC++ 2008, which I call from Excel. This works fine. Then I included in my code call to GSL library (just one extra call to statistics gsl package). It compiles and builds, but when I try to call the function from my LIB1.DLL for Excel I'm getting error file not found: LIB1.DLL
I think that it is the GSL lib that is not found by LIB1.DLL...
