Guidance for setting up Qt for Cross Compilation
-
Hi,
I am trying to cross compile for my target application on my host machine, but I'm not sure how to go about it. I have read a few blogs, but I am not able to connect the pieces. Here is my configuration details:
Qt : 5.4.0 (Qt Creator 3.3.0)
Host Machine: x86 Fedora 19 (64 bit)
Target Machine: Intel x86 Debian LinuxI have Qt5 installed on my target device and can build on the target or build on my host using the root file system of my target device by using chroot.
I want to be able to cross compile from QtCreator and launch the application on my target device. I have no problem in setting up the SSH and the sending the application over to the target, but I am not sure how to configure the compiler and the tool chain.
I have the entire root file system of my target on my host machine, so I should have access to all of the Qt5 libraries and compiler for my target, but I'm not sure how to set this up. Here are my questions:
- Where should I get the compiler for my target? Should I use /usr/bin/g++ (target rfs)
- Where do I get qmake for the target? The following failed to load TargetRFS#/usr/local/Qt-5.4.0/bin/qmake
- Do I need to obtain a tool chain for this ?
- Anything else I might need to do?
Thanks in advance for any help on this.

Hi,
Did I read correctly that you have one 32bit and one 64bit machine ?
-
They are both 64 bit machines.
-
Then why cross-compile ? The only big difference is then the distribution
-
Okay, that's what I thought. But when I used the native compilers on my host machine and loaded the application on my target I got an error stdin is not a tty when the application ran.

How are you calling your application in the target ? Do you have a window manager ?
