How to statically link a lib file into your QT project. Need help. Have questions:

[Davidm71]

Hi,

Experimenting with creating a static library to link against a test program. Lets say I create a Factorial class with header and class files when I compile it (using MSVC compiler lets say in Windows) I get a lib file but QT Creator popsup a message that "executable not found". Not sure why thats happening.

Second afterwards I create my test program widget QT doesn't autocomplete the header includer file. Maybe because path is wrong and I need header files besides not just the obj or dll files??

So if anyone could please write up step by step instructions I would appreciate it.

Thanks

Because a library is not an executable. Creator just tells you, that it cannot execute a lib.

Sure, you need the headers to compile and the lib to link against your library - no matter if you link static or dynamic.

The usual way is to set up a SUBDIRS project to have lib and app together.
