Use Qt with MSVC++ 11 Compiler to compile external 3rd party library

Hello everybody,

I have been a quiet reader for some time. I am new to Qt and C++ in general. I started a couple of days ago with this topic and have read and followed a lot of tutorials online. Many problems have been solved and many have come up. This forum came up a couple of times and has helped me a as well.

At the moment I try to compile a library for scrypt. It is plain C/C++. The project I am using is from http://www.tarsnap.com/scrypt.html

I have followed the steps in a different thread on here that explains in very high detail what to do.

Basically I opened the CMD and moved to the lib folder of the download. I then used

Code:

---

qmake -project

---

To get a .pro file, I opened the .pro file and changed it to TEMPLATE = lib, resulting into this .pro file:

Code:

However, when I try to compile it I get a few error message:

My compiler settings are:

I know that <stdlib.h> etc are very basic header files and that they should be available, I have not seen inttypes.h etc. I am not really sure how to go about this creating a library from a 3rd party project.
Basically I just want to compile this as a lib and then be able to use it as an external library in my main project.

I hope somebody could help me.

I am looking forward to reading your answers.

All the best,
Richard
