arm-linux-gnueabihf gcc8.3交叉編譯工具搭建教程

一、運行環境

1.1  執行機環境

ld	GNU ld (GNU Binutils for Raspbian) 2.31.1
ldd	ldd (Debian GLIBC 2.28-10+rpi1) 2.28   Copyright (C) 2018 Free Software Foundation, Inc.
gcc	(Raspbian 8.3.0-6+rpi1) 8.3.0   Copyright (C) 2018 Free Software Foundation, Inc.
arm	ARMv7 ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0

1.2  交叉編譯機環境

Linux 桌面系統 Ubuntu 16.04.4 LTS

二、編譯步驟

2.1  用戶目錄下新建gcc_all文件夾，下載binutils-2.31.tar.bz2  gcc-8.3.0.tar.gz  glibc-2.28.tar.bz2  linux。

cd ~
mkdir gcc_all && cd gcc_all
wget https://ftpmirror.gnu.org/binutils/binutils-2.31.tar.bz2
wget https://ftpmirror.gnu.org/glibc/glibc-2.28.tar.bz2
wget https://ftpmirror.gnu.org/gcc/gcc-8.3.0/gcc-8.3.0.tar.gz
git clone --depth=1 https://github.com/raspberrypi/linux

2.2  提取所有壓縮文件

tar xf binutils-2.31.tar.bz2
tar xf glibc-2.28.tar.bz2
tar xf gcc-8.3.0.tar.gz
rm *.tar.*

2.3 下載GCC8.3需要的一些資源文件到源碼中，刪除沒用的壓縮包

cd gcc-8.3.0
contrib/download_prerequisites
rm *.tar.*

2.4 創建交叉編譯的安裝文件夾，並添加到PATH路徑中

cd ~/gcc_all
sudo mkdir -p /opt/cross-pi-gcc
sudo chown $USER /opt/cross-pi-gcc
export PATH=/opt/cross-pi-gcc/bin:$PATH

2.5 安裝Linux內核頭文件到交叉編譯安裝文件夾

cd ~/gcc_all
cd linux
KERNEL=kernel7

make ARCH=arm INSTALL_HDR_PATH=/opt/cross-pi-gcc/arm-linux-gnueabihf headers_install

2.6 編譯安裝Binutils 2.31

cd ~/gcc_all
mkdir build-binutils && cd build-binutils

../binutils-2.31/configure --prefix=/opt/cross-pi-gcc --target=arm-linux-gnueabihf --with-arch=armv6 --with-fpu=vfp --with-float=hard --disable-multilib

make -j8
make install

2.7 編譯安裝GCC

 

cd ~/gcc_all
mkdir build-gcc && cd build-gcc

../gcc-8.3.0/configure --prefix=/opt/cross-pi-gcc --target=arm-linux-gnueabihf --enable-languages=c,c++,fortran --with-arch=armv6 --with-fpu=vfp --with-float=hard --disable-multilib

make -j8 all-gcc
make install-gcc

2.8 編譯安裝glibc2.28

 

cd ~/gcc_all
mkdir build-glibc && cd build-glibc

../glibc-2.28/configure --prefix=/opt/cross-pi-gcc/arm-linux-gnueabihf --build=$MACHTYPE --host=arm-linux-gnueabihf --target=arm-linux-gnueabihf --with-arch=armv6 --with-fpu=vfp --with-float=hard --with-headers=/opt/cross-pi-gcc/arm-linux-gnueabihf/include --disable-multilib libc_cv_forced_unwind=yes

make install-bootstrap-headers=yes install-headers

make -j8 csu/subdir_lib

install csu/crt1.o csu/crti.o csu/crtn.o /opt/cross-pi-gcc/arm-linux-gnueabihf/lib

arm-linux-gnueabihf-gcc -nostdlib -nostartfiles -shared -x c /dev/null -o /opt/cross-pi-gcc/arm-linux-gnueabihf/lib/libc.so

touch /opt/cross-pi-gcc/arm-linux-gnueabihf/include/gnu/stubs.h

錯誤處理：* LD_LIBRARY_PATH shouldn’t contain the current directory when

                  * building glibc. Please change theenvironment variable

                  * and run configure again.

解決：記錄LD_LIBRARY_PATH的值（echo $ LD_LIBRARY_PATH=），清空該變量（# LD_LIBRARY_PATH=），編譯安裝結束後重新添加。

 

 

2.9 回到GCC編譯安裝libgcc

 

cd ..
cd build-gcc
make -j8 all-target-libgcc
make install-target-libgcc

2.10 結束安裝Glibc

 

cd ..
cd build-glibc
make -j8
make install

2.11 最後完成安裝GCC8.3.0

 

cd ..
cd build-gcc
make -j8
make install
cd ..

安裝完成後系統中存在arm-linux-gnueabihf-gcc-8.3.0。可在控制命令中查到：

​

三、測試

新建一個test.c文件如下：

#include “stdio.h”
int main()
{
    printf(“test arm-linux-gnueabihf cross-compile-tools\r\n”);
    return 0;
}

執行編譯：

arm-linux-gnueabihf-gcc test.c -o out

查看編譯信息：

file out
out: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, not stripped

編譯完成。
