Trouble building Qt-Embedded 4.8.3 using ARM Toolchain

[Pluvius]

Hello!

I've been building Qt-embedded for quite some time now using (arm-none-linux-gnueabi), but this time around I was faced with a nasty error when I tried to build Qt using the Raspberry Pi toolchain (armv6j-hardfloat-linux-gnueabi-), and I'd appreciate your help and insight on it. Steps taken:

changing

#

QMAKE_STRIP             = armv6j-hardfloat-linux-gnueabi-strip
 
load(qt_config)

I'd appreciate some help here, thank you

[pradeepreddyg95]

try this steps ..
clean your qt configuaration
export PATH=your compiler Path:$PATH
add -v option to your qt configure -v will shows log in this you can find what is happening ...
I hope it will solve your problem ...

[binaural]

Why not to choose some build system to do it for you? I can recommend Buildroot.

Cheers,

marek

Sorry for my late response, but thank you very much guys , that solved my problem!

I found I had to manually fixup my $PATH env var too like Qt/E page and unset $CC and $CXX when building qt 4.8 from source. Normally these are all set by our OE angstrom compiler when building SDK examples, but these had to be stripped when building full source tree.

One more item I ran into was with the 4.8.3 webkit option kept getting disabled by the configure script. I tracked this down to extra quotes in QMAKE_CXX setting which failed the gcc -dumpversion check. Don't know why the OE guys put their QMAKE_ vars all in quotes.
