RVCT的Linux环境变量配置 ARM® RVDS™ 4.1(b713)

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/4.1/462/include/unix
export ARMCC41LIB=/opt/armrvds/4.1BLD713/RVCT/Data/4.1/462/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/2.2/349/include/unix
    export RVCT22LIB=$ARMROOT/RVCT/Data/2.2/349/lib
    export PATH=$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 thatinstall_directory isC:\Keil\ARM.
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_directory\RV31\INC
ARMCCnnLIB	The default location of the ARM standard C and C++ library files: install_directory\RV31\LIB 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 forinstall_directory\RV31\LIB the linker searches: LIB LIB\armlib LIB\cpplib
ARMINC	Used only if you do not specify the compiler option-J andARMCCnnINC 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 andARMCCnnLIB 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. IfTMP 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]Replacenn 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：

• ARM、Thumb C 和 C++ 编译器 armcc
• NEON 向量化编译器，可使用命令 armcc --vectorize 进行调用
• ARM 和 Thumb 汇编程序 armasm
• ARM 链接器 armlink
• ARM 库管理程序 armar
• ARM 图像转换实用工具 fromelf
• 支持库。
