Building the Qt environment for ARM9 development board-EEWORLD

Collect

Note: Do not use the QT that comes with the package or installed using apt-get. If there is any, delete it. The development board must be able to mount NFS. This article uses other people's teaching materials, but I have slightly modified them. Because when I first looked for files to do it, I found many mistakes that were easy to make, which are explained here.

Required original documents:

a. arm-linux-gcc-3.4.1.tar.bz2

b. Qt-4.6.3-arm.tar.bz2

c. Qt-4.6.3-x86.tar.bz2

d. Qt-4.7.0.tar.bz2

e. Qt-sdk-linux-x86-opensource_2010.02.bin

f. tslib-1.4.tar.gz

Steps:

1. Check if there is g++ on the computer: g++ --version,

If not, install it using the following command: sudo apt-get install g++

2. Check if there is arm-linux-gcc: arm-linux-gcc –version,

　　If not, please use step 4 to install it. If yes, skip step 4.

4. Unzip arm-linux-gcc-3.4.1.tar.bz2

sudo tar jxvf arm-linux-gcc-3.4.1.tar.bz2 -C / Automatically decompress to usr/local

Enter /usr/local/arm/3.4.1/bin/ and enter pwd

Set to environment variables: sudo gedit /etc/environment

Add it in the format: /usr/local/arm/3.4.1/bin (arm-linux-gcc path)

After saving, source /etc/environment (to make the environment variables take effect)

arm-linux-gcc Checks if the command exists

5http://www.appfreeapp.com/, unzip and install the touch screen driver

1 # sudo apt-get install libtool 2 # sudo apt-get install autoconf 3 #sudo apt-get install automake 4 #tar xzvf tslib-1.4.tar.gz 5 #cd tslib 6 # ./autogen.sh 7 # CC= arm-linux-gcc 8 # echo "ac_cv_func_malloc_0_nonnull=yes" > arm-linux.cache 9 # ./configure --prefix=/opt/ts/ --host=arm-linux --cache-file=arm-linux. cache10 # make11 # sudo make install

There may be a parameter error. Add 0 after the parameter in lines 227 and 229 of the file /tests/calibrate.c and try again.

make

6. Add the compiled touch screen driver to the board

6.1、cp the cross-compiled ts file to the corresponding directory in the development board, where include in warez-bb

The pkgconfig directory under the directory and lib does not need to be copied.

cp -rf /opt/ts /home/zrx/s3c2440_recover/opt/ts
