The most common C-language compiler currently available under Linux is GCC (GNU Compiler Collection), a compiler system that complies with the ANSI C standard in the GNU Project and compiles programs written in languages such as C, C + +, and Object C. GCC is not only very powerful, but also extremely flexible in structure. The most commendable thing is that it can support various languages through differen

We know that for GCC to install the default version through yum in CentOS, CentOS 5 is 4.1.2, CentOS 6 is 4.4.7, and CentOS 7 is 4.8.3.Most of the time, compiling and installing software requires a later version of GCC. Otherwise, an error is reported.So how to upgrade the GCC version?First, check the GCC version numbe

Clang advantages over the GCC compiler:Faster compile timesLess compile outputThe error prompt is more friendly , such as clang can directly indicate a relatively simple error location and the way it "thinks" in the compilation process.built-in static analysis tools allow static analysis of code (CLANG-ANALYZE). That's what GCC can't do.Focus , because clang only needs to complete lexical and syntactic anal

Linux under C Development- gcc , gdb usage Author: zccst The process of learning should be a process of accumulation, there is no, and less to much, but not like the monkeys down the mountain. September is the first time system learning gcc, GDB, makefile (see previous blog). Now as an integral part of the embedded system, the decision to learn again, feel a bit more understanding deepened.

, finally, code that can be run on the target platform is generated. the tool chain for cross-compilation can be downloaded from the Internet or created by yourself. however, the compiler is not omnipotent. Due to version restrictions, an error will be reported when compiling some programs. common cross-compilation tool chains include: (1) Cross-2.95.3 tar: This version is earlier and is not used except for compiling Vivi. (2) arm920t-eabi.tgz: 4.1.2 version of the compiler, Eabi support, can co

GCC optionsGCC has more than 100 compilation options available. many of these options may never be used, but some of the main options will be frequently used. many GCC options include more than one character. therefore, you must specify the respective characters for each option, and, just like most Linux commands, you cannot separate the characters with a group of options. for example, the following two com
