Compile a software from 32 to 64 bit

Question

I have a source code of a local tool which currently works on 32 bit VS 2008. Now I want to compile it on my system which is 64 bit and has VS2010. How can I achieve the compilation? Should I install the whole VS2008 or is it sufficient to install the 32-bit compiler and use 2010 IDE, and if so from where I can download the necessary tools to compile?

The same source code I want to upgrade ie compile it in 64 bit VS 2010. The tool has a dependency on Qt4.7.1 and Zlib 1.2.8. How can I achieve this up gradation?

Answer 1

In order to achieve that you need 64-bit libraries of Qt and Zlib. Once you have all necessary 64-bit dll's required for your project, then you will need to link those libraries to linker in your project.

Compiling your tool with these libraries should be fine.
