Hi..... I am following this tutorial for compiling qt4 for mini2440. http://mini2440vietnam.blogspot.in/2011/04/upgrade-qt462-in-mini2440.html and I am getting this error on step.... make after configuring. Error: selected processor does not support Thumb mode `swp r4,r3,[r2]' Can anyone help ?
Have you tried copying and pasting the error into Google? I tried and got lots of hits but as I am not using QT I have no idea which would help you but it would be a good start. Dave...
I tried it but i could not get how to solve it. I am damn sure that i did something wrong in my qmake.conf file.
Shows us your qmake.conf file. This was one problem I didn't have trying to get QT to work on the mini2440. And that tutorial was the most useful one, when I was working on Qt.
This is the content of my qmake.conf file. It is as per the tutorial. I made necessary changes according to my tool chain. Everything else is fine. # # 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 = /usr/bin/arm-linux-gnueabi-gcc -march=armv4t -mtune=arm920t -O0 -lts QMAKE_CXX = /usr/bin/arm-linux-gnueabi-g++ -march=armv4t -mtune=arm920t -O0 -lts QMAKE_LINK = /usr/bin/arm-linux-gnueabi-g++ -march=armv4t -mtune=arm920t -O0 -lts QMAKE_LINK_SHLIB = /usr/bin/arm-linux-gnueabi-g++ -march=armv4t -mtune=arm920t -O0 -lts # modifications to linux.conf QMAKE_AR = /usr/bin/arm-linux-gnueabi-ar cqs QMAKE_OBJCOPY = /usr/bin/arm-linux-gnueabi-objcopy QMAKE_STRIP = /usr/bin/arm-linux-gnueabi-strip QMAKE_INCDIR += /home/tslib/include/ QMAKE_LIBDIR += /home/tslib/lib/ QMAKE_CFLAGS_RELEASE += -march=armv4 -mtune=arm920t QMAKE_CFLAGS_DEBUG += -march=armv4t -mtune=arm920t QMAKE_CFLAGS_MT += -march=armv4t -mtune=arm920t QMAKE_CFLAGS_MT_DBG += -march=armv4t -mtune=arm920t QMAKE_CFLAGS_MT_DLL += -march=armv4t -mtune=arm920t QMAKE_CFLAGS_MT_DLLDBG += -march=armv4t -mtune=arm920t QMAKE_CFLAGS_SHLIB += -march=armv4t -mtune=arm920t QMAKE_CFLAGS_THREAD += -march=armv4t -mtune=arm920t QMAKE_CFLAGS_WARN_OFF += -march=armv4t -mtune=arm920t QMAKE_CFLAGS_WARN_ON += -march=armv4t -mtune=arm920t QMAKE_CXXFLAGS_DEBUG += -march=armv4t -mtune=arm920t QMAKE_CXXFLAGS_MT += -march=armv4t -mtune=arm920t QMAKE_CXXFLAGS_MT_DBG += -march=armv4t -mtune=arm920t QMAKE_CXXFLAGS_MT_DLL += -march=armv4t -mtune=arm920t QMAKE_CXXFLAGS_MT_DLLDBG += -march=armv4t -mtune=arm920t QMAKE_CXXFLAGS_RELEASE += -march=armv4t -mtune=arm920t QMAKE_CXXFLAGS_SHLIB += -march=armv4t -mtune=arm920t QMAKE_CXXFLAGS_THREAD += -march=armv4t -mtune=arm920t QMAKE_CXXFLAGS_WARN_OFF += -march=armv4t -mtune=arm920t QMAKE_CXXFLAGS_WARN_ON += -march=armv4t -mtune=arm920t load(qt_config)
However let me tell you one more thing. I am trying to compile 4.6.3 and tut is about compiling 4.6.2. Hope it doesn't make any difference.
I am getting this kind of statement while configuring. ./configure: 6390: ./configure: arm920t: not found
Maybe, this might make a difference # modifications to g++.conf QMAKE_CC = /usr/local/arm/4.3.2/bin/arm-none-linux-gnueabi-gcc -msoft-float -D__GCC_FLOAT_NOT_NEEDED -march=armv4t -mtune=arm920t -O0 -lts QMAKE_CXX = /usr/local/arm/4.3.2/bin/arm-none-linux-gnueabi-g++ -msoft-float -D__GCC_FLOAT_NOT_NEEDED -march=armv4t -mtune=arm920t -O0 -lts QMAKE_LINK = /usr/local/arm/4.3.2/bin/arm-none-linux-gnueabi-g++ -msoft-float -D__GCC_FLOAT_NOT_NEEDED -march=armv4t -mtune=arm920t -O0 -lts QMAKE_LINK_SHLIB = /usr/local/arm/4.3.2/bin/arm-none-linux-gnueabi-g++ -msoft-float -D__GCC_FLOAT_NOT_NEEDED -march=armv4t -mtune=arm920t -O0 -lts Adjust for your compiler and the path to it.
Here's my re-write of that tutorial. Rename it as a Qt tutorial.doc Good luck.
Hi... @ dave.... I tried your tutorial but it is showing me the same error. I don't understand the problem yet. First while configuring i see a line mentioning. ./configure: 6390: ./configure: arm920t: not found @ dave --> what difference does it make ? I made it as per my toolchain path. # modifications to g++.conf QMAKE_CC = /usr/local/arm/4.3.2/bin/arm-none-linux-gnueabi-gcc -msoft-float -D__GCC_FLOAT_NOT_NEEDED -march=armv4t -mtune=arm920t -O0 -lts QMAKE_CXX = /usr/local/arm/4.3.2/bin/arm-none-linux-gnueabi-g++ -msoft-float -D__GCC_FLOAT_NOT_NEEDED -march=armv4t -mtune=arm920t -O0 -lts QMAKE_LINK = /usr/local/arm/4.3.2/bin/arm-none-linux-gnueabi-g++ -msoft-float -D__GCC_FLOAT_NOT_NEEDED -march=armv4t -mtune=arm920t -O0 -lts QMAKE_LINK_SHLIB = /usr/local/arm/4.3.2/bin/arm-none-linux-gnueabi-g++ -msoft-float -D__GCC_FLOAT_NOT_NEEDED -march=armv4t -mtune=arm920t -O0 -lts Let me know if you have any tutorial to develop gui over existing qtopia image.
Doubt if it will help, but which kernel are you using? There are tutorials out there, but I never went any further after I got the /demo/browser to work. And that was quite painful.
As in ? My pc or kernel for mini2440 ? I am running 2.6.32.2 kernel for mini2440. I am running ubuntu 12.04 on my laptop.
> arm-linux-gnueabi-gcc Which toolchain does that version come in?
arm-linux-gnueabi-gcc --version arm-linux-gnueabi-gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 Copyright (C) 2011 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. It shows me this when I execute arm-linux-gnueabi-gcc --version. Which toolchain do you recommend ? Earlier i was trying, arm-linux-gcc however it was showing me error while using that .... .arm-none-linux-gcc not found. So I shifted to arm-linux-gnueabi-gcc. I compiled kernel 2.6.32.2 and uploaded on the board. It was working fine with supervivi64M --> (my zImage) --> root_qtopia64M.bin (shipped with dvd). So I guess toolchain works fine. Let me know your views.
I followed this tutorial to set up that toolchain. http://www.acmesystems.it/foxg20_arm9_cross_compiler
Referring to the link: Except you changed to another cross-compiler (4.6.3) From my understanding if the correct library versions are NOT compiled with the same cross-compiler, as the kernel, you MIGHT have problems. Looks like you are OK. There are rules that generally result in success when you are building from scratch. Using one cross-compiler for everything seems to be one of them. In my experience it is "minefield" of things that can go wrong. The toolchain I use comes with the Pengutronix package and using it has reduced my frustration level by orders of magnitude. Keep hacking away at it, it is a good learning experience. Good luck!
@ davef Can you assist me through this ? I am planning to use arm-linux-gcc 4.4.3 toolchain for this. I extracted it and set the path according to procedure. however when i type arm-linux-gcc --version command, it throws me an error as below : /opt/FriendlyARM/toolschain/4.4.3/bin/arm-linux-gcc: 15: exec: /opt/FriendlyARM/toolschain/4.4.3/bin/.arm-none-linux-gnueabi-gcc: not found Let me know if you have any solution to this program.
Problem:- "/opt/FriendlyARM/toolschain/4.4.3/bin/.arm-none-linux-gnueabi-gcc: not found " Discription :- You are running on x64 bit host and trying to use compile with 32bit tool-chain. Solution :- "sudo apt-get install lib32ncurses5"
