My first trip to ARM-LINUX

My first trip to ARM-LINUX-Linux general technology-Linux programming and kernel information, which is detailed below. Recently, I was asked by my friends to develop a handheld System Based on arm9-samsung ARM 2440. Because it is a handheld system, it is natural to use the operating system. Since the source code is not fully open, if you want to create a custom system, you should call bill (Bill retired ?). So now we are focusing on Linux. Linux is familiar with and unfamiliar with things. Every day, some friends say that you haven't run Linux this year, but I am not interested in it. I have left the desktop Windows system, even some copy paste commands can beat yourself to death. We had to work hard for this project.

Since yesterday (in fact, the day before yesterday), it is loaded into the QT-4.4.0 for graphics editing, because QT is a cross-platform similar VC. NET and other development systems, and the QT library is still relatively complete, but I will not use it.

This is QT:

Now let's talk about the difference between AMD and INTEL. In my book, The T5450 desktop is AMD 3600 × 2, which is almost 2 GB of memory. In theory, the Compilation speed should be similar. However, my AMD Compilation speed should be more than half an hour later than INTEL's. Alas, if we want to develop products in the future, we 'd better use INTEL.

Yesterday, after being depressed for half a day, I finally finished KDEVELOP. I was prepared to make a big effort, but I was unable to install it, saying that I lacked a lot of libraries. Here is the official KDEVELOP:

I have also committed a dogmatism, thinking that he can install these in the case of a FEDORA8 installation. Yesterday, whereis did not find these databases for half a day. (Whereis is quite convenient !) In the future, I will summarize all the Linux commands I use. After you click the corresponding kde development package in the Software Update, you can simply wait for the update to be downloaded. I didn't expect it to be finished. This is a nightmare. I can't help it. After all, the official website of FEDORA8 is outside China, and I want to find a website in China to complete the update. Suddenly I found a website and said I could # yum manually add these software. Then I suddenly realized that it took only 15 minutes to run the # yum install KDEVELOP command, and the familiar KDEVELOP environment came out. Ah, if it is FEDORA, you can use more YUM commands. (By the way, I upgraded pidgin mplayer .) At in the middle of the night, I really couldn't read the book. My first QT program still couldn't run.

This website is a collection of RPM packages. You can find the following information if you need anything:

It is not easy to find embedded systems. If you want to transplant them, you need to understand the Linux kernel thoroughly. To install a graphic interface, it would be a nightmare for people like qt c ++ who are born electronically. Compile C ++ and even machine code.
