[Buildroot] QT support for Buildroot RFS.

[Mahanteshwari Hiremath]

Hi,
          I am trying to buid buildroot RFS with QT supprt.
I have enabled C++ support in toolchain and Qt support in package selection --> Graphic libraries --> Qt.
after 'make'  I can see qmake getting installed in staging/usr/bin.

What are the necessary changes(settings) i have to do inorder to get qmake installed in target/bin and libraries in target/lib(nothing but RFS).

Kindly suggest me.

What are you going to do? Are you going to compile the final program
on your target device directly? What is the problem with
cross-compiling?

qmake is installed in output/host/usr/bin, not inside the staging
directory.

We only support cross-compilation of Qt application: qmake is not
installed on the target. Just use the qmake in output/host/usr/bin to
cross-compile your Qt application from your host machine.

The Qt libraries are already installed in output/target/usr/lib if you
have enabled Qt in the configuration.

Hi,
Cross compiling is not a problem, I can able to do it. But I want to compile my program directly on target device using qmake, I want to have qmake support on my target.
So only I wanted some suggestions in executing this.

This is not supported in the current Buildroot, which does not build
qmake for the target. Buildroot is designed for cross-compilation, i.e
the situation where your target is rather slow compared to your
development PC, and therefore cases for which native compilation is not
possible or really too painful. We have some support to have a native
toolchain on the target (so you can build standard C or C++ programs on
the target), but we don't support that for Qt.

If you want, you can work on extending the Qt .mk file to also generate
a qmake for the target, but I think it's going to be very complicated
for a benefit that isn't really obvious to me.

Alternatively, you can download and compile Qt on your target itself,
with the native toolchain that you installed there.

You could even (but this is really far-fetched) install buildroot on
your target, and use it to generate qmake (which will be in
output/host *on your target*).
