QT build - cross compilation error

[qtch]

Hello
when Iḿ trying to build QT (cross compilation) I have error with message:
typing: ./configure -opensource -confirm-license -prefix /opt/qt-arm -no-qt3support -embedded arm -little-endian -xplatform qws/linux-arm-ti3517 -qtlibinfix E

and when i type ¨make¨ error occurs:

g++: error trying to exec 'cc1plus': execvp: No such file or directory
Assembler messages:

I have problems with building Qt for embedded too:/

makespecs/qws/linux-arm-g++ looks like this:

include(../../common/g++.conf)
include(../../common/linux.conf)
include(../../common/qws.conf)

# modifications to g++.conf
QMAKE_CC = arm-linux-gnueabi-gcc
QMAKE_CXX = arm-linux-gnueabi-g++
QMAKE_LINK = arm-linux-gnueabi-g++
QMAKE_LINK_SHLIB = arm-linux-gnueabi-g++

# modifications to linux.conf
QMAKE_AR = arm-linux-gnueabi-ar cqs
QMAKE_OBJCOPY = arm-linux-gnueabi-objcopy
QMAKE_STRIP = arm-linux-gnueabi-strip

load(qt_config)

my configure line is:
./configure -embedded arm -shared -release -no-largefile -qt-sql-sqlite -no-qt3support -no-phonon -no-svg -no-scripttools -nomake demo -nomake examples -qt-decoration-default -no-opengl -qt-gfx-linuxfb -little-endian


after configure I'm using 'make' and after a while I have this issue:

thanks for Your help

[wysota]

Is this the result of configure or make? Did configure build the bootstrap library for you?

I would suggest disabling build of the tools, it's very unlikely you'll ever need Assistant for the embedded system.

[7ymekk]

thanks for a quick reply. This is a result of make. 'find' command doesn't see any *bootstrap* files except source ones. ' -nomake tools' added but this issue still occurs

ps. this problem occurs on my old Ubuntu 10.04 and fresh installed Ubuntu 11.04...

[wysota]

At the same place? Hardly possible if you disabled the tools. Did you run make clean? The bootstrap library is in src/tools/bootstrap and is called libbootstrap.a.

[7ymekk]

yes, it occurs in the same moment and I've made 'make clean' before reruning 'configure' and 'make' commands.

find of bootstrap looks like this:

root@ryba-VirtualBox:/# find -name *bootstrap*
./var/log/bootstrap.log
./home/ryba/qt-everywhere-opensource-src-4.7.3/src/corelib/arch/qatomic_bootstrap.h
./home/ryba/qt-everywhere-opensource-src-4.7.3/src/tools/bootstrap

./usr/lib/ure/lib/bootstrap.uno.so
./lib/firmware/dsp56k/bootstrap.asm
./lib/firmware/dsp56k/bootstrap.bin
root@ryba-VirtualBox:/#

ps.some files was computed before this issue. e.g qmake was built

[wysota]

So adding -nomake tools doesn't prevent the compilation from building tools?

[7ymekk]

apparently not because I compared this error message with the previous one and it is exactly the same message

I removed all sources dir and extracted it again. configure with command:

./configure -embedded arm -shared -release -no-largefile -qt-sql-sqlite -no-qt3support -no-phonon -no-svg -no-scripttools -nomake demo -nomake examples -nomake tools -qt-decoration-default -no-opengl -qt-gfx-linuxfb -little-endian

,after that 'make' and tools are built...

I don't want to give up but I have no idea what is wrong...all forums, websites etc. shows excatly the same procedure

[wysota]

Run make distclean, make confclean, then run configure again and before running make check what got built. Also somewhere during its output configure should output a log of enabled and disabled features, please post it here.
