~/linux/downloads directory. 3. The compilation process needs to use the following software, the system itself is not installed, you can run the installation command well in advance, because the compilation will take at least half an hour, if the dependent software is not installed halfway through the error exits, only from the beginning, that is a waste of time.sudo apt-get install Bison flex build-essential Patch Libncurses5-devSpecific work steps:1. Modify the System configuration1.1 Set the

, 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

Misunderstanding 1: GCC can only compile C code, while G ++ can only compile C ++ codeBoth can be used, but note the following:1. suffix. c, GCC treats it as a C program, while G ++ treats it as a C ++ program; suffix. CPP, both of which are considered as C ++ programs. Note that although C ++ is a superset of C, their syntax requirements are different. C ++ syntax rules are more rigorous.2. in the compilat

This article describes the tools that can be used for C application development and debugging under Linux. The thrust of this article is to explain how to use the C compiler and other C programming tools under Lin

Recompile the GCC-4.3.0-general Linux technology-Linux programming and kernel information, below is the details to read. GCC is a set of program compilers in Unix, including C, C ++, Fortran77, and Java. Upgrading GCC helps shorten the compilation process and generate more efficient programs, however, the compiled program may be large. the latest version is 4. 3.

_ ASM _ is the macro definition of the GCC keyword ASM: # DEFINE _ ASM _ ASM _ or ASM is used to declare an inline assembly expression. Therefore, any inline assembly expression starts with it and is indispensable. 2. Instruction List The Instruction List is a sequence of Assembly commands. It can be empty, for example, __asm _ volatile _ (""); or _ ASM __(""); they are all completely legal inline assembly expressions, but these two statements have no

prefix as the prefix of the-iwithprefix Option (5)-iwithprefix dir: add the directory to the second include path. The directory name is composed of prefix and Dir, And the prefix is-iprefix. For example, if I have a head file in/root/cpptest/INC named ctest. H, in my ctest. C # include "ctest. H" A. G ++ ctest. C will report an error saying that the ctest. h file cannot be found. B. G ++-idirafter/root/cpptest/INC/ctest. C will be compiled and run C. The same effect as B G ++-iprefix/root/cppte

What exactly happened behind gcc-static hello. c? You may often use gcc-static ***. c. What commands and libraries are used for this static link? First, let's analyze what libc. a is. We already know that xxx. so is a dynamic link library, xxx. o is a static link library or relocated file, And/bin/bash is an executable file. Libc. a is actually a collection of many relocated files, and generally only one fu

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
