But code size is a difficult thing to influence manually, and the compiler is in a much better position to make this change across all of your software modules.īy the time your program is working you may already know, or have a pretty good idea, which subroutines and modules are the most critical for overall code efficiency.
And there are many things you can do to improve the efficiency of those sections by hand. Execution speed is usually important only within certain time-critical and/or frequently-executed sections of the code. Since you can’t have the compiler perform both types of optimization for you, I recommend letting it do what it can to reduce the size of your program. Given that single piece of information, the compiler’s optimization phase can make the appropriate choice whenever a speed vs. It is up to the programmer to decide which of these improvements is most important to her.
In fact, an improvement in one of these areas may have a negative impact on the other. Your program can either be made faster or smaller, but not both. However, most of the optimization techniques that are performed by a compiler involve a tradeoff between execution speed and code size. Some degree of code optimization is provided by all modern C and C++ compilers. The goal of this final step is to make the working program run on the lower-cost “production” version of the hardware. These boards are used to get the software working correctly, and then the final phase of the project becomes code optimization. And toward that end there are usually one or more “development” boards around, each with additional memory and/or a faster processor. Of course, during the software development phase of the project it is more important to get the program to work correctly. The need for low cost versions of our products drives hardware designers to provide just barely enough memory and processing power to get the job done.

Uninstall Codeblocks and then first install MinGW and then install Codeblocks.Though getting the software to work correctly seems like the logical last step for a project, this is not always the case in embedded systems development. Note: If you encountered problems running the debugger with CodeBlocks, do a clean installation. In Executable, the path should be C:\Program Files\codeblocks\MinGW\bin\gdb.exe or C:\MinGW\bin\gdb.exe if you have installed MinGW compiler before installing Codeblocks. Similarly, for debugger path: Settings > Debugger > GDB/CDB debugger > Default.Now select the “Toolchain Executables” tab from the below tabs and check the Compiler’s Installation Directory is set to “ C:\Program Files\codeblocks\MinGW. In the selected compiler, by default, it shows GNU GCC Compiler. Go to menu options and click on Settings > Compiler.We need to verify the Compiler and Debugger path (this step is optional). Now we have installed Codeblocks on windows.Click YES, and then it shows the compiler Codeblocks detected. Wait for a minute for installation to complete.On the new pop-up, don’t do anything, just click Next and then change the installation directory if you want (default directory recommended).
