#./configure -host=arm-linux ac_cv_func_malloc_0_nonnull=yes -cache-file=arm-linux.cache -prefix=/usr/local/tslib # tar -zxvf tslib-1.4.tar.gz -Because the following prefix specifies to be installed under /usr/local, this file cannot be placed under /usr/local ! It can be placed in other directories such as /home. These three must be checked, otherwise there may be compilation errors! First you need to check whether the software is installed,
#Qt creator mini2440 install#
Therefore, compile and install tslib first, so that it can be packaged and compiled when Qt is compiled later. It is usually used as the adaptation layer of the touch screen driver and is the upper application. for the samples obtained by the touch screen driver. It is an open source program that can provide functions such as filtering, debounce, calibration, etc. Tslib is a software library used for calibration of resistive touch screens. The first step is of course to be patient!īefore continuing to write down, let’s introduce my environment: These two packages are qt-everywhere-opensource-src-4.8.0.tar.gz located at under the webpage, there is another tslib-1.4.bar.gz is located at. Today’s topic is the construction of the Qt environment including environment variables. After building the cross tool chain, we only need two download packages to start work. I already have an article about cross tool chain in my blog before. Qt provides a wealth of GUI controls, which is more suitable for making embedded GUI! So I will use Qt to develop embedded software like everyone else! Although C programming is not difficult, If you use Qt this kind of encapsulated class library to operate, there will be a lot less bugs, and more worth mentioning is GUI programming.
The C language programming of Linux itself is very annoying, such as serial programming. I have the right to use it as a class library. Let me first talk about why you want to use Qt this stuff! After I used it, I learned that this language is really good.
