[Qt-creator] Cross-compiling for ARM with qt creator

[Uwe Fechner]

Hello,

first of all thanks for the fast response to my last question.

Now my next question:
I try to crosscompile a "Hello world!" console application
for ARM.

My ARM toolchain is installed in:
/usr/arm-linux-gnueabi

I use QT-Creator 3.1 32 bit on Ubuntu Linux 10.10.

In Tools-Options I defined a toolchain of type GCC with
the following compiler path:
/usr/bin/arm-linux-gnueabi-g++

For qmake I use the additional argument:
-spec qws/linux-arm-g++

Now it compiles, but I get the warning:

Running build steps for project FirstQT...

Configuration unchanged, skipping qmake step.

Starting: "/usr/bin/make" -w

make: Gehe in Verzeichnis 
'/home/ufechner/00QT-Software/KiteBrain/FirstQT-arm'

/usr/lib/gcc/arm-linux-gnueabi/4.3.2/libgcc_s.so, not found (try using 
-rpath or -rpath-link)

make: Verlasse Verzeichnis 
'/home/ufechner/00QT-Software/KiteBrain/FirstQT-arm'

The process "/usr/bin/make" exited normally.


I tried to set the rpath in different ways, but it doesn t help.

The correct version of libc.so is located in:
/usr/arm-linux-gnueabi/lib/

Any ideas?

Best regards:

Uwe Fechner
