fortran program calling c++ dll - dll only found if I copy it over??

[brochamb]

Hi there,

I have a program written in Fortran that calls functions from a dll written in C++. But when I run it I get an error saying that it failed to start because the dll was not found. Everything works fine if i copy the dll over to where the Fortran executable is, but I won't be able to do that later on.

Is there a ways to give the DLLIMPORT command a path to where the dll is? I have the .lib file added to my project, which the project doesn't compile without, but it doesn't seem to help with locating the dll.

No, there isn't. Your DLL is dependent on other DLLs that can't be found. Is your DLL built as a "debug configuration"? If so, rebuild it as a "release configuration" and that may help. But you probably have to install the MSVC run-time DLLs. Which version of Visual Studio are you running?

Thanks for the reply, I'll try building as release when i get to work tomorrow. I am running it with Visual Studio .NET 2003. The machines do have 2005 also, but I had been using 2003 for everything else so I haven't tried 05 yet.

Visual C++ 2005 redistributables package

For Visual Studio.NET 2003, you will probably have to copy msvcr71.dll along with your executable.
