Problem compiling neo-hokean dll

[jon98]

Hi. I am trying to compile the dll for the neo-hookean material from the site, but I am encountering various problems. I am using Windows 10, and Visual Studio Professional 2015. I never used Visual Studio before, and never programmed in C++ .
I created a new win32 project, and select the option for dll. Then I included the FENeoHookeanPI.h as header, and the dll.cpp and FENeoHookeanPI.cpp as source file. In the properties of the project I do the following steps for the release and debug configuration:
1) In VC++ Directories I add the "include" folder from the FeBio in the include directories. I also add the "lib" folder from the Vs2015 in the library directories.
2) In C/C++ General, I add the "include" folder in the Additional Include Directories and Additional #using Directories.
3) In Linker General, I add the "lib" folder in the Additional Library Directories.
4) In Linker Input, I add "FECore.lib" e "FEBioMech.lib" in the Additional Dependencies.
Both the debug and configuration are x64 in the Platform. When I go in the release and try to build the solution, I have 31 errors (they are listed below). Any help is welcomed. The files are attached

Hi Jon,

Can you check if the WIN32 macro is defined? Go to the project properties, then under Configuration Properties -> C/C++ -> Preprocessor, find the "Preprocessor definitions" and see if WIN32 is on the list. If not, add it and try to rebuild again. Let me know what you find.

Cheers,

Steve

Hi. Thanks for the quick reply. In the preprocessor definition there is by default:
"NDEBUG
_WINDOWS
_USRDLL
WIN32PROJECT1_EXPORTS"
I tried to add WIN32 there (I just go in the field and write WIN32, I don't know if this is correct) but it did not change anything. It still has 31 errors, which I listed in my previous post. I am attaching some images from my configuration:

Hmm, not sure what the issue could be. Your configuration properties look okay to me. It almost looks like the include statement at the top of the file is not there. Can you check if the first line of the FENeoHookeanPI.cpp is:

#include "FENeoHookeanPI.h"

After a lot of trial and error, I found my mistake. The Visual Studio 2015 uses the option precompiled header by default, and so it created a "stdafx.h" by default. So when I included the command #include "stdafx.h" as the first command in the FENeoHookeanPI.cpp and dllmain.cpp, the code worked. Interesting (at least for a noob in c++ like me), if I included stdafx.h after the #include "FENeoHookeanPI.h", it will give the errors which I was encountering (and that was the problem).
Anyway, thanks for the help.
