I am trying to compile Qt embedded for ARM. I have followed the instructions both here and here. I am using latest Angstrom toolchain and qt-embedded-linux-opensource-src-4.5.3 and I am using Ubuntu 10.10 x86.
Here steps I past:
-
Configured qws/linux-arm-g++/qmake.conf file for my toolchain. Here it’s content:
# # qmake configuration for building with arm-linux-g++ # include(../../common/g++.conf) include(../../common/linux.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) -
Set my toolchain path:
export PATH=/home/olcay/angstrom/arm/bin:$PATH -
Configured qt with:
./configure -arch arm -little-endian -xplatform qws/linux-arm-g++ -
Run make.
While running make I am getting this error:
make[1]: Entering directory `/home/olcay/qt-embedded/src/corelib'

make[1]: Leaving directory `/home/olcay/qt-embedded/src/corelib'
make: *** [sub-corelib-make_default-ordered] Error 2
I have also noticed that while config there is a warning and same error line in make:
The system floating point format could not be detected.
This may cause data to be generated in a wrong format
Turn on verbose messaging (-v) to see the final report.
/home/olcay/angstrom/arm/bin/arm-angstrom-linux-gnueabi-g++: 1: ELF: not found
/home/olcay/angstrom/arm/bin/arm-angstrom-linux-gnueabi-g++: 2: Syntax error: word unexpected (expecting ")")
And changing configure line as @Luca Carlon described does not solve the problem.
Please help me!
Thanks in advance.
I have noticed that I have downloaded my Angstrom tool-chain for 64 bit host platform but I am using 32 bit host. After downloading correct tool-chain I have managed to compile Qt. And I found that an “ELF not found” error occurs when you try to run an application which is not build for your architecture.
