Developing with Ubuntu Qt Creator ToolChain for Angstrom Beaglebone (Arm Cortex-a8)

blaroche

you don't need sudo for configrue and make.

let me run thru the steps myself, maybe i missed a step. i was just using bits of notes i had from the past.

blaroche

ok. all was fine for me. i'm using ubuntu (32 bit), same qt source and toolchain as you. so i prolly didn't explain as step that good.

source your toolchain env file:
source /usr/local/angstrom/arm/environment-setup
confirm arm binaries are in your PATH env. from any directory type:
arm-angstrom and hit tab a few times. auto complete should show you a bunch file files named arm-angstrom-linux-gnueabi-something
setup your mkspecs. delete everything in the following file:
/home/xenland/qt-everywhere-opensource-src-4.8.3/mkspecs/qws/linux-arm-gnueabi-g++/qmake.conf

copy in the following:
@#

qmake configuration for building with arm-none-linux-gnueabi-g++

include(../../common/linux.conf)
include(../../common/gcc-base-unix.conf)
include(../../common/g++-unix.conf)
include(../../common/qws.conf)

modifications to g++.conf

QMAKE_CC = arm-angstrom-linux-gnueabi-gcc
QMAKE_CXX = arm-angstrom-linux-gnueabi-g++
QMAKE_LINK = arm-angstrom-linux-gnueabi-g++
QMAKE_LINK_SHLIB = arm-angstrom-linux-gnueabi-g++

modifications to linux.conf

QMAKE_AR = arm-angstrom-linux-gnueabi-ar cqs
QMAKE_OBJCOPY = arm-angstrom-linux-gnueabi-objcopy
QMAKE_STRIP = arm-angstrom-linux-gnueabi-strip

load(qt_config)

@

cd to /home/xenland/qt-everywhere-opensource-src-4.8.3/ and run the following command:
@./configure -v -opensource -confirm-license -xplatform qws/linux-arm-gnueabi-g++ -embedded arm -little-endian -host-big-endian -prefix /usr/local/beaglebone/qt4.8-arm -no-cups -no-accessibility -reduce-relocations -no-nas-sound -no-sm -no-nis -qt-libjpeg -qt-libpng -qt-zlib -no-sql-ibase -no-sql-mysql -no-sql-odbc -no-sql-psql -no-sql-sqlite -no-sql-sqlite2 -no-pch -no-dbus -no-glib -no-phonon -no-phonon-backend -no-webkit -no-multimedia -no-audio-backend -no-qt3support -nomake examples -nomake demos -nomake docs -nomake translations -no-qt3support -exceptions -no-fast

@

i usually just copy the configure command into a file called config in the source directory, and chmod 755, and run the file ./config

hopefully you don't get any errors, and then you can run:
make
if you have a mutiple core cpu, you can run: make -j2, or make -j4 to speed things up.

then
sudo make install

i've never tried on a 64bit machine, good suggestion, thank you.
try this configure.
but first, cleanup. run
make confclean

./configure -v -opensource -confirm-license -xplatform qws/linux-arm-gnueabi-g++ -embedded arm -little-endian -host-little-endian -prefix /usr/local/beaglebone/qt4.8-arm -no-cups -no-accessibility -reduce-relocations -no-nas-sound -no-sm -no-nis -qt-libjpeg -qt-libpng -qt-zlib -no-sql-ibase -no-sql-mysql -no-sql-odbc -no-sql-psql -no-sql-sqlite -no-sql-sqlite2 -no-pch -no-dbus -no-glib -no-phonon -no-phonon-backend -no-webkit -no-multimedia -no-audio-backend -no-qt3support -nomake examples -nomake demos -nomake docs -nomake translations -no-qt3support -exceptions -no-fast

NuckNuck

I did * make confclean* which make claimed it couldn't find any target file/config so i just did the ./configure above with the last post that includes the little-endian flag and now I recieve this error, Thanks again for the help I'm excited to get to BeagleBone programming

Hmm... Google suggests that the "-m64" is not supported by these cross-compilers. I don't have a 64-bit machine, so I'm not sure where that is being set.

Go to your Qt root folder and call this to find out:
@
grep m64 *
@

You might be able to manually remove the flag and continue.

blaroche

hmm. lets go back and see if we can find a smaller configure that you can build on.

see where you get with this one:
@./configure -v -opensource -confirm-license -xplatform qws/linux-arm-gnueabi-g++ -embedded arm -little-endian -host-big-endian -prefix /usr/local/beaglebone/qt4.8-arm @

then maybe try this:
@./configure -v -opensource -confirm-license -xplatform qws/linux-arm-gnueabi-g++ -embedded arm -prefix /usr/local/beaglebone/qt4.8-arm @

i'm with JSKH, i've never cross compiled on 64 bit.

blaroche

another one to try...
@
./configure -v -opensource -confirm-license -xplatform qws/linux-arm-gnueabi-g++ -embedded arm -little-endian -prefix /usr/local/beaglebone/qt4.8-arm

That first configure seems to have done the trick, This was the end result

@
Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr/local/beaglebone/qt4.8-arm

To reconfigure, run 'make confclean' and 'configure'.
@

So i ran make and recieved the following error

@make[1]: arm-none-linux-gnueabi-g++: Command not found
make[1]: *** [.obj/release-shared-emb-arm/qabstractanimation.o] Error 127
make[1]: Leaving directory `/home/xenland/qt-everywhere-opensource-src-4.8.3/src/corelib'
make: *** [sub-corelib-make_default-ordered] Error 2@

Its odd that it says its trying to execute arm-none-linux-gnueabi-g++

blaroche

check your mkspecs again.
look at this file:
/home/xenland/qt-everywhere-opensource-src-4.8.3/mkspecs/qws/linux-arm-gnueabi-g++/qmake.conf

you should see stuff for:
arm-angstrom-linux-gnueabi-*
not
arm-none-linux-gnueabi-*

should look like the below:
@ #
# qmake configuration for building with arm-none-linux-gnueabi-g++
#

include(../../common/linux.conf)
include(../../common/gcc-base-unix.conf)
include(../../common/g++-unix.conf)

load(qt_config)

The conf file was saying the arm-none so I changed it to the one you provided and I get relativly the same error take a look:

blaroche

now looks like the toolchain binaries aren't found in your PATH var.
source the toolchain env file, type:
source /usr/local/angstrom/arm/environment-setup

then type:
arm-angstrom-linux and hit tab a few times and make sure it can find arm-angstrom-linux-gnueabi-g++

see if that gets you further.
