File not found error for unincluded headers

[ablan]

I have a c++ driver header file which have the lines
#ifndef Q_OS_WIN
#include <linux/i2c.h>
#include <linux/i2c-dev.h>
#endif
When I try to compile this on Windows, it fails to compile and gives file not found error for the i2c.h and i2c-dev.h. But they are not supposed to be included at all since the #ifndef statement should have excluded them. I do not get what is causing this error.

@ablan said in File not found error for unincluded headers:

Q_OS_WIN

Did you include QtGlobal header file where you're using Q_OS_WIN?

Hi,

Beside the good point made by @jsulm, to avoid such a case, you should rather use

#ifdef Q_OS_LINUX

as there are other OSs that Qt supports that will not have these includes.

Thanks for the replies, I included QtGlobal, but it is still giving me the same file not found compilation error.

I found solution. The header file was not included in the HEADERS of .pro file. I just add it to the HEADERS and the compilation error disappeared.
