阿里云OSS-C-SDK交叉编译环境配置

显示全部楼层 · 2023-9-3 20:26:55

开发板环境是arm32架构的，开发环境是ubuntu18.04。

交叉编译环境配置

首先下载交叉编译工具：https://developer.arm.com/downloads/-/gnu-a 解压得到文件夹：gcc-arm-10.3-2021.07-x86_64-arm-none-linux-gnueabihf 新建文件夹 mkdir /opt/tool-chain 将编译链放在新建的文件夹下： sudo mv gcc-arm-10.3-2021.07-x86_64-arm-none-linux-gnueabihf /opt/tool-chain/ 将交叉编译环境添加到环境变量：编辑.bashrc新增以下三行：

export ARCH=arm
export CROSS_COMPILE=arm-none-linux-gnueabihf-
export PATH=$PATH:/opt/tool-chain/gcc-arm-10.3-2021.07-x86_64-arm-none-linux-gnueabihf/bin

使其生效：source ~/.bashrc 通过查看交叉编译链的版本，确认是否成功配置：arm-none-linux-gnueabihf-gcc -v 有以上输出表示配置成功！需要明确：交叉编译环境的路径为：/opt/tool-chain/gcc-arm-10.3-2021.07-x86_64-arm-none-linux-gnueabihf/

第三方库安装

sudo apt install cmake

curl 库安装

安装包：libcurl-7.32.0 下载地址：https://curl.se/download/curl-7.32.0.tar.gz 解压后得到：curl-7.32.0文件夹安装过程：

cd curl-7.32.0
./configure --prefix=/home/cclike/curl --host=arm-none-linux CC=arm-none-linux-gnueabihf-gcc CXX=arm-none-linux-gnueabihf-g++
make
make install

apr 库安装

安装包：apr-1.5.2 下载地址：https://archive.apache.org/dist/apr/apr-1.5.2.tar.gz 解压后得到：apr-1.5.2文件夹安装过程（安装之前可以先看看遇到的问题）：

cd apr-1.5.2
./configure --prefix=/home/cclike/apr-1 --host=arm-none-linux CC=arm-none-linux-gnueabihf-gcc CXX=arm-none-linux-gnueabihf-g++  ac_cv_file__dev_zero=yes ac_cv_func_setpgrp_void=yes apr_cv_process_shared_works=yes apr_cv_mutex_robust_shared=yes apr_cv_tcp_nodelay_with_cork=yes ap_void_ptr_lt_long=no
make  // 确保已经安装make：sudo apt install make
make install

遇到的问题：

执行./configuare的时候，会遇到下面的问题：

config.status: executing libtool commands
rm: cannot remove 'libtoolT': No such file or directory
config.status: executing default commands

解决方案：编辑configuare文件，给RM添加啊参数：-f

执行make的时候遇到的问题：

解决方案：

gcc -Wall -O2 -DCROSS_COMPILE tools/gen_test_char.c -s -o gen_test_char  // 确保已安装gcc sudo apt install gcc
./gen_test_char > ../include/private/apr_escape_test_char.h

修改当前目录的Makefile，禁止生成gen_test_char 保存退出之后重新执行make

遇到下面的问题：

直接编辑对应文件，注释掉iovec结构体重新直接make，编译通过

expat 库安装

安装这个库是因为在编译apr-util库的时候会报expat库的错

xml/apr_xml.c:35:19: fatal error: expat.h: No such file or directory#include <expat.h>

安装包：expat-2.2.5.tar.bz2 下载地址：https://github.com/libexpat/libexpat/releases/download/R_2_2_5/expat-2.2.5.tar.bz2 解压生成：expat-2.2.5 安装过程：

cd expat-2.2.5
./configure --prefix=/home/cclike/expat --host=arm-none-linux CC=arm-none-linux-gnueabihf-gcc CXX=arm-none-linux-gnueabihf-g++
make
make install

apr-util 库安装

安装包：apr-util-1.5.4 下载地址：https://archive.apache.org/dist/apr/apr-util-1.5.4.tar.gz 解压生成：apr-util-1.5.4 安装过程：

cd apr-util-1.5.4
./configure --prefix=/home/cclike/apr-util --host=arm-none-linux CC=arm-none-linux-gnueabihf-gcc CXX=arm-none-linux-gnueabihf-g++ --with-apr=/home/cclike/apr-1 --with-expat=/home/cclike/expat
make
make install

libmxml 库安装

安装包：mxml-2.8

下载地址：https://github.com/michaelrsweet/mxml/releases/download/release-2.8/mxml-2.8.tar.gz

解压生成：mxml-2.8

安装过程：

cd mxml-2.8
./configure --prefix=/home/cclike/mxml --host=arm-none-linux CC=arm-none-linux-gnueabihf-gcc CXX=arm-none-linux-gnueabihf-g++
make
make install

遇到下面的问题：

目前还没有找到解决办法，但是上面的make动作已经生成了我们需要的头文件和链接库

所以只需要将对应的文件拷贝出来即可：

到这里第三方库基本上就安装完成了，说到底安装第三方库也只是为了得到对应的库文件和头文件。我的做法是把所有的库文件进行汇总，方便再makefile中进行引用。

OSS-C-SDK 安装

安装包：aliyun-oss-c-sdk-3.5.0.tar.gz 下载地址：https://github.com/aliyun/aliyun-oss-c-sdk/archive/refs/tags/3.5.0.tar.gz 解压后得到：aliyun-oss-c-sdk-3.5.0 安装步骤：

cd aliyun-oss-c-sdk-3.5.0

编辑CMakeList.txt将下面内容添加到文件开头

SET(CMAKE_SYSTEM_NAME Linux)
SET(TOOLCHAIN_DIR "/opt/tool-chain/arm-rockchip830-linux-uclibcgnueabihf/")
SET(CMAKE_SYSTEM_PROCESSOR MIPS)
SET(CMAKE_FIND_ROOT_PATH ${TOOLCHAIN_DIR})
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
SET(CMAKE_C_COMPILER ${TOOLCHAIN_DIR}/bin/arm-rockchip830-linux-uclibcgnueabihf-gcc)
SET(CMAKE_CXX_COMPILER ${TOOLCHAIN_DIR}/bin/arm-rockchip830-linux-uclibcgnueabihf-g++)

修改apr和apr-util的路径为我们前面安装的路径：

FIND_PROGRAM(APR_CONFIG_BIN NAMES apr-config apr-1-config PATHS /home/cclike/RV1109/oss/third_lib/apr-1/bin /usr/local/bin /usr/local/apr/bin/)
FIND_PROGRAM(APU_CONFIG_BIN NAMES apu-config apu-1-config PATHS /home/cclike/RV1109/oss/third_lib/apr-util/bin /usr/local/bin /usr/local/apr/bin/)

注释掉文件最后两行，这些是不需要的

# add_subdirectory(oss_c_sdk_sample)
# add_subdirectory(oss_c_sdk_test)
