linux安装配置交叉编译器arm-linux-gnueabi-gcc

linux安装配置交叉编译器arm-linux-gnueabi-gcc要使我们在x86架构下运⾏的程序迁移⾄ARM架构的开发板中运⾏时，需要通过交叉编译器将x86下编写的程序进⾏编译后，开发版才能运⾏。

在安装之前我们需要了解，什么是。

⼀、下载交叉编译器1.新版本的下载⼊⼝如下图所⽰：下载流程如下所⽰：“GNU Toolchain Integration Builds → 11.0-2021.03-1 → arm-linux-gnueabihf → gcc-linaro-11.0.1-2021.03-x86_64_arm-linux-gnueabihf.tar.xz。

”注意：随着时间的不同可能版本号有所变化，不过下载流程应给是⼀样的，除⾮⽹站的变化很⼤。

2.历史版本下载⼊⼝如下图所⽰：下载流程如下所⽰：“View Releases → components → toolchain → binaries → 6.2-2016.11 → arm-linux-gnueabihf → gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf.tar.xz”⼆、安装交叉编译器进⼊linux系统，在/usr/local下创建arm⽂件，将下载的交叉编译⼯具链拷贝到linux系统的/usr/local/arm路径下，并进项解压，如下图所⽰：三、设置环境变量打开/etc/profile⽂件sudo vim /etc/profile在⽂件的最后⼀⾏添加交叉编译链的路径，完成后保存退出export PATH=$PATH:/usr/local/arm/gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf/bin如下图所⽰：重新加载环境变量的配置⽂件source /etc/profile检验是否安装成功arm-linux-gnueabihf-gcc -v如果出现以下信息说明安装成功。

Ubuntu18.04安装arm-linux-gcc交叉编译器的两种方法（附下载地址）

Ubuntu18.04安装arm-linux-gcc交叉编译器的两种⽅法（附下载地址）⽅法⼀：我们都知道Ubuntu有⼀个专门⽤来安装软件的⼯具apt，我们可以⽤它来全⾃动安装arm-linux-gcc。

此⽅法安装的是最新版的，但是此⽅法需要FQ，否则99%会失败，这就是为什么⽹上⼤多都⽤压缩包安装的原因：⾸先Ctrl+Alt+T弹出终端，使⽤如下命令进⾏arm-linux-gcc的安装：sudo apt-get install gcc-arm-linux-gnueabihf 使⽤如下命令进⾏arm-linux-g++的安装：sudo apt-get install g++-arm-linux-gnueabihf 如果要卸载时使⽤如下命令进⾏移除，arm-linux-gcc的卸载：sudo apt-get remove gcc-arm-linux-gnueabihf arm-linux-g++的卸载：sudo apt-get remove g++-arm-linux-gnueabihfsudo tar -xjvf /tmp/arm-linux-gcc-3.4.5-glibc-2.3.6.tar.bz2 3.解压完成后，再在（/usr/local）中创建⼀个新⽬录arm，即在Terminal中输⼊以下命令：sudo mkdir /usr/local/arm 4.创建arm⽬录成功后，还需要给它解放全部权限，即在Terminal中输⼊以下命令：sudo chmod 777 /usr/local/arm 5.在解压出来的⽬录中找到并把整个arm-linux-gcc-3.4.5-glibc-2.3.6⽬录复制到刚刚建好的arm⽬录中，命令如下：sudo cp -r gcc-3.4.5-glibc-2.3.6 /usr/local/arm 6.打开（/etc/profile）配置环境变量和库变量，⽬的是以后可以在任何位置使⽤该交叉编译器，命令如下：sudo vi /etc/profile 7.⽤vi或者vim打开后，在⽂件最后添加两⾏，并输⼊以下代码：第⼀⾏是添加执⾏程序的环境变量，第⼆⾏是库⽂件的路径export PATH=$PATH:/usr/local/arm/gcc-3.4.5-glibc-2.3.6/binexport LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/arm/gcc-3.4.5-glibc-2.3.6/lib 8.使⽤source命令重新加载⽣效该配置⽂件source /etc/profile 9.检验是否安装成功，在 Terminal 输⼊以下命令输出版本信息：arm-linux-gcc -v 10.若有以下报错参考解决办法：报错：bash: /usr/local/arm/4.2.2-eabi/usr/bin/arm-linux-gcc-4.2.2: No such file or directory 解决sudo apt-get install libc6-i386 该库中包括ia32-libs, lib32z1, lib32ncurses5等等依赖。

arm-linux-gcc 4.3.2编译安装过程

arm-linux-gcc 4.3.2编译安装过程收藏arm-linux-gcc 4.3.2编译安装过程本文由《我的arm-gcc工具编译安装过程》修正而成，红字部分为与原作不同之处，希望对大家有所帮助。

原文地址：/blog/static/28351497200902193223687/我的编译环境是在ubuntu8.10 amd64，gcc版本为4.3.2，编译的linux内核版本为2.6.8，故后面需要修改少许内核头文件。

开始前确认环境里有texinfo, gawk(注意mawk编译glibc header时会有问题), bison, flex，没有就安装它们。

>sudo apt-get install texinfo gawk bison flex工作的目录是用户目录下源文件放在目录cross_source里编译的工作目录是cross_buildxxx 就是存放解压出来的源代码，例如binutils-2.19.tar.bz2，解压放在binutils-2.19 xxx_build 用于编译的目录，例如binutils-2.19.tar.bz2，编译目录是binutils-2.19_build用到的文件是binutils-2.19.tar.bz2gcc-core-4.3.2.tar.bz2gcc-g++-4.3.2.tar.bz2mpfr-2.3.2.tar.bz2gmp-4.2.4.tar.bz2linux-2.6.28.tar.bz2glibc-ports-2.7.tar.bz2glibc-2.7.tar.bz2首先创建目录>mkdir cross_source>mkdir cross_build>cd cross_build1编译，安装binutilsbinutils的配置和编译安装，binutils的编译一般不会遇到什么问题，至少我没有遇到。

>sudo apt-get install texinfo>tar -jxvf ../cross_source/binutils-2.19.tar.bz2根据[Bug gas/7026] New: ARM target wont build, error: format not a string literal and no format arguments，修改tc-arm.c>mkdir binutils-2.19_build>cd binutils-2.19_build>../binutils-2.19/configure --target=arm-linux --prefix=/usr/local/arm/4.3.2 >make>sudo make all install这就会把binutils的编译结果安装到/usr/local/arm/4.3.2/里binutils安装后需要把路径导出。

libusb交叉编译

libusb交叉编译libusb是一款开源的、跨平台的USB设备驱动程序的库。

在进行嵌入式设备开发时，可能需要将libusb编译成交叉平台的库，这篇文章将介绍如何进行libusb的交叉编译。

首先，需要安装交叉编译工具链，我们以arm-linux-gcc为例：```。

sudo apt-get install gcc-arm-linux-gnueabihf。

```。

接下来，进行交叉编译：```。

export CC=arm-linux-gnueabihf-gcc。

export CXX=arm-linux-gnueabihf-g++。

export AR=arm-linux-gnueabihf-ar。

./configure --host=arm-linux --prefix=/usr/arm-linux-gnueabihf。

make。

make install。

```。

其中，`--host`参数指定交叉编译的目标平台，`--prefix`参数指定编译后的库文件安装的位置。

编译完成后，在指定的安装路径下会生成libusb库和头文件。

以上是libusb的交叉编译的基本过程，如果需要使用libusb，还需要在编译应用程序时对libusb进行链接。

下面是一个编译libusb应用程序的示例：```。

export CC=arm-linux-gnueabihf-gcc。

$CC -o my_program my_program.c -lusb-1.0。

```。

其中，`-lusb-1.0`指定链接libusb库。

qt程序移植到arm开发板

qt程序移植到arm开发板1、安装交叉编译⼯具链arm-linux-gcc●复制arm-linux-gcc-4.4.3.tar.gz到/home/tools⽂件夹⾥●解压命令tar xvzf arm-linux-gcc-4.4.3.tar.gz -C / （解压⽂件到根⽬录下）注意以上命令必须要有-C⽽且是⼤写，后边有个空格也要注意。

注意查看解压的路径，将解压⽣成的⽂件移动到usr/local/arm⽬录下●vi /etc/profile●在⽂件的末尾加上PATH=/usr/local/arm/4.4.3/bin:$PATH●输⼊命令：source /etc/profile（使刚修改的⽂件⽴即⽣效）●查看arm-linux-gcc版本arm-linux-gcc -v注意：此⽅法只对当前登录⽤户有效，更换⽤户后修改当前登录⽤户/etc/profile即可2、tslib编译与安装tslib是电阻式触摸屏⽤于校准的⼀个软件库，是⼀个开源的程序，能够为触摸屏驱动获得的采样提供诸如滤波、去抖、校准等功能，通常作为触摸屏驱动的适配层，为上层的应⽤提供了⼀个统⼀的接⼝。

因此这⾥先编译安装tslib，这样在后⾯编译Qt的时候才能打包编译进去。

●需要检查⼀下软件是否安装sudo apt-get install automakesudo apt-get install autogensudo apt-get install autoconf●确定以上⼯具都已经安装后，复制tslib-1.4.tar到/home/tools⽂件夹⾥tar -zxvf tslib-1.4.tar.gzcd tslib./autogen.sh./configure --host=arm-linux ac_cv_func_malloc_0_nonnull=yes --cache-file=arm-linux.cache -prefix=/usr/local/tslibmakemake install-prefix=/usr/local/tslib是指定安装路径，其实包括下⽂的安装配置，路径都可以不指定，默认就是安装到/usr/local/⽬录下若出现错误：configure.ac:25: error: possibly undefined macro: AC_DISABLE_STAT ICIf this token and others are legitimate, please use m4_pattern_al low.See the Autoconf documentation.configure.ac:26: error: possibly undefined macro: AC_ENABLE_SHARE Dconfigure.ac:27: error: possibly undefined macro: AC_LIBTOOL_DLOP ENconfigure.ac:28: error: possibly undefined macro: AC_PROG_LIBTOOL autoreconf: /usr/bin/autoconf failed with exit status: 1解决⽅法：apt-get install libtool3、Qt的交叉编译与安装和PC平台下的编译类似，通过运⾏./configure进⾏配置⽣成makefile⽂件，然后编译安装，只是因为是针对嵌⼊式平台需要进⾏⼀些针对性配置，这⾥⽣成⼀个⾃动配置⽂件，可以通过修改⽂件来⽅便的更改配置。

交叉编译实验报告

一、实验目的本次实验旨在通过交叉编译，了解并掌握交叉编译的基本原理和操作方法，提高在嵌入式系统开发中对编译器配置和编译过程的掌握能力。

交叉编译是指在一个平台上编译生成可在另一个平台上运行的程序，这对于嵌入式系统开发尤为重要，因为嵌入式设备通常资源有限，而开发环境与运行环境可能不同。

二、实验环境1. 主机平台：Windows 102. 目标平台：Linux（假设为Raspberry Pi）3. 编译工具：GCC4. 软件包：交叉编译工具链（如交叉工具链crosstool-ng）三、实验步骤1. 安装交叉编译工具链（1）在主机上安装crosstool-ng。

```bashsudo apt-get install crosstool-ng```（2）使用crosstool-ng生成交叉编译工具链。

```bashcrosstool-NG-1.22.0/src/crosstool-NG-1.22.0/configure --toolchain-build=x86_64-build --toolchain-target=arm-linux-gnueabihf --sysroot=/path/to/raspberry-pi/rootfsmake```（3）安装交叉编译工具链。

```bashsudo make install```2. 编写测试程序（1）创建一个简单的C程序，如`hello_world.c`。

```c#include <stdio.h>int main() {printf("Hello, World!\n");return 0;}```3. 交叉编译程序（1）使用交叉编译器编译程序。

```basharm-linux-gnueabihf-gcc hello_world.c -o hello_world ```（2）检查编译生成的可执行文件。

```bashls -l hello_world```4. 将可执行文件传输到目标平台（1）使用SSH将可执行文件传输到目标平台。

arm-linux-gcc交叉编译工具链安装
陈伟
解压arm-linux-gcc-3.4.1.tar.bz2
#tar zxvf arm-linux-gcc-3.4.1.tar.bz2
1.解压过程需要一段时间，解压后的文件形成了usr/local/ 文件夹，
进入该文件夹，将arm文件夹拷贝到/usr/local/下
#cd usr/local/
#cp -rv arm /usr/local/
现在交叉编译程序集都在/usr/local/arm/3.4.1/bin下面了
2.修改环境变量，把交叉编译器的路径加入到PATH。

修改~/.bashrc文件,编辑.bash_profile也行
#vim ~/.bashrc
在最后加上：
export PATH=$PATH:/usr/local/arm/3.4.1/bin export PATH
也可以：
#export PATH=$PATH:/usr/local/arm/3.4.1/bin
注：(这只能在当前的终端下才是有效的！)
3.立即使新的环境变量生效，不用重启电脑：
#source /root/.bashrc
4.检查是否将路径加入到PATH：
# echo $PATH
显示的内容中有/usr/local/arm/bin，说明已经将交叉编译器的路径加入PATH。

至此，交叉编译环境安装完成。

5. 测试是否安装成功
# arm-linux-gcc -v。
