Makefile:412: recipe for target 'ui_mainwindow.h' failed

Hi,

What version of Qt are you using ?
How did you install it ?

Momeneh

I used bellow link for cross compile Qt 5.11 on Raspberry Pi :
https://wiki.qt.io/RaspberryPi2EGLFS

SGaist

Since you cross-compiled Qt, how did you got qmake on your Raspberry Pi ?

Momeneh

I used "sudo apt-get install qt5-default" command to get qmake.

This qmake does NOT belong to your cross-compiled Qt but to Qt provided by Raspbian!

Ok, thanks, but now i don't know what should i do?

@Momeneh You should compile Qt directly on your RaspberryPi, then you will have qmake there.
If you cross compile then tools like qmake are built for the host machine, because they are needed there.

SGaist

In addition to @jsulm, if the Qt version provided by Raspbian (or whatever distribution you are running) is enough, just install the corresponding development packages.

I should connect to RaspberryPi remotely with ssh and i use wiringPi library in my code, now i want to compile and run it on RaspberryPi and i don't know how to do it without qmake command.

@Momeneh

You cross compiled Qt for Raspberry Pi, right? Then you can build your app on your PC, copy the binary to your Raspberry Pi and run it there (you will need to copy cross compiled Qt libs, which are used by your app, to Raspberry Pi as well).
If you really want to build directly on Raspberry Pi, then install Qt provided by Raspbian as @SGaist said and use it, no need to build Qt by yourself.

You should decide first whether you want 1 or 2...
