我是靠谱客的博主闪闪秋天，最近开发中收集的这篇文章主要介绍RVCT的Linux环境变量配置 ARM® RVDS™ 4.1(b713)ARM 编译器工具链，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

下载解压 armrvds.tar.gz到/opt 下

在自己的build.sh下导入RVCT的环境变量配置ARM® RVDS™4.1(b713)：

export ARMROOT=/opt/armrvds/4.1BLD713/RVCT/Programs/4.1/713/linux-pentium
export ARM_BIN=/opt/armrvds/4.1BLD713/RVCT/Programs/4.1/713/linux-pentium
export ARMCC41INC=/opt/armrvds/4.1BLD713/RVCT/Data/4.1/713/include/unix
export ARMCC41LIB=/opt/armrvds/4.1BLD713/RVCT/Data/4.1/713/lib
export PATH=$ARM_BIN:$PATH

MAKE -rs

RVCT的环境变量配置ARM® RVDS™2.2(b616)：

       export ARMROOT=/opt/ARM_2.2
    export ARM_BIN=$ARMROOT/RVCT/Programs/2.2/616/linux-pentium
    export RVCT22INC=$ARMROOT/RVCT/Data/2.2/616/include/unix
    export RVCT22LIB=$ARMROOT/RVCT/Data/2.2/616/lib
    export PATH=$ARM_BIN:$PATH

MAKE -rs

Toolchain environment variables

The ARM Compiler toolchain does not require environment variables to be set. However, there are situations where you might want to set environment variables. For example, if you want to specify additional command-line options for armcc, but you do not want to modify your build scripts, then you can specify the options usingARMCCnn_CCOPT.

The environment variables used by the toolchain are:

Table 1. Environment variables used by the toolchain

Environment variable^[a]	Setting
`ARMROOT`	Your installation directory root (`install_directory`). This documentation assumes that`install_directory` is`C:KeilARM`.
`ARMCCnn_ASMOPT`	An optional environment variable to define additional assembler options that are to be used outside your regular makefile. The options listed appear before any options specified for thearmasm command in the makefile. Therefore, any options specified in the makefile might override the options listed in this environment variable.
`ARMCCnn_CCOPT`	An optional environment variable to define additional compiler options that are to be used outside your regular makefile. The options listed appear before any options specified for thearmcc command in the makefile. Therefore, any options specified in the makefile might override the options listed in this environment variable.
`ARMCCnn_FROMELFOPT`	An optional environment variable to define additionalfromelf image converter options that are to be used outside your regular makefile. The options listed appear before any options specified for thefromelf command in the makefile. Therefore, any options specified in the makefile might override the options listed in this environment variable.
`ARMCCnn_LINKOPT`	An optional environment variable to define additional linker options that are to be used outside your regular makefile. The options listed appear before any options specified for thearmlink command in the makefile. Therefore, any options specified in the makefile might override the options listed in this environment variable.
`ARMCCnnINC`	The default system include path. That is, the path used to search for header filenames enclosed in angle-brackets. The compiler option`-J` overrides this environment variable. The default location of the compiler include files is: `install_directoryRV31INC`
`ARMCCnnLIB`	The default location of the ARM standard C and C++ library files: `install_directoryRV31LIB` The compiler option `--libpath` overrides this environment variable. Note If you include a path separator at the end of the path, the linker searches that directory and the subdirectories. So for`install_directoryRV31LIB` the linker searches: LIB `LIBarmlib` `LIBcpplib`
`ARMINC`	Used only if you do not specify the compiler option`-J` and`ARMCCnnINC` is either not set or is empty. See the description of `ARMCCnnINC` for more information.
`ARMLIB`	Used only if you do not specify the compiler option`--libpath` and`ARMCCnnLIB` is either not set or is empty. See the description of `ARMCCnnLIB` for more information.
`CYGPATH`	The location of the `cygpath.exe` file on your system in Cygwin path format. For example: `C:/cygwin/bin/cygpath.exe` You must set this if you want to specify paths in Cygwin format for the compilation tools.
`TMP`	Used on Windows platforms to specify the directory to be used for temporary files. If`TMP` is not defined, or if it is set to the name of a directory that does not exist, temporary files are created in the current working directory.
^[a]Replace`nn` with the version of the toolchain you are using. For example,`ARMCC41INC` if you are using ARM Compiler toolchain v4.1.

ARM 编译器工具链

ARM 编译器工具链可用于编译由 C、C++ 或 ARM 汇编语言源代码编写的程序。它可为 32 位 ARM、16 位 Thumb 和 Thumb-2 指令集生成优化代码，并支持完整的符合 ISO 标准的 C 和 C++ 代码。此外，它还通过向量化 NEON 编译器支持 NEON SIMD 指令集。

ARM 编译器工具链由以下组件组成：
