七牛云ARM64交叉编译流程

前些时间遇到七牛云第三方编译问题,现把整个流程记录如下,供大家参考.

我们使用的开发板是周立功的m1808,核心是rk1808.环境在Vmware的linux下面

一.编译依赖库curl

百度云下载链接:

链接：https://pan.baidu.com/s/1J-hKk4Pce9gf5rBcqcOtYw 
提取码：pkgb

1.下载源文件到本地

2.解压文件到当前目录

tar xvf curl-7.58.0.tar.xz

3.进入目录curl-xxx,创建build文件夹

mkdir build
cd build

4.加载第三方编译链的目录环境变量

export PATH=$PATH:/opt/zlg/m1808-sdk-v1.3.1-ga/host/bin  //加载aarch64-linux-gnu目录

我们的编译链接版本是

#aarch64-linux-gnu-gcc -v
使用内建 specs。
COLLECT_GCC=/opt/zlg/m1808-sdk-v1.3.1-ga_2020.12.31/host/../gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc

线程模型：posix
gcc 版本 6.3.1 20170404 (Linaro GCC 6.3-2017.05)

5.检测配置并编译源码

参数解释：
【–host】：就是用【config.guess】获取的；
【CC】【CXX】：交叉编译工具链gcc和g++名称；
【–with-protoc】：已经编译好的主机平台protoc二进制文件路径；
【–prefix】：交叉编译后安装目录。

../configure --host=aarch64-linux-gnu --prefix=/usr
make
make install DESTDIR=/home/zlgmcu/Desktop/curl-7.58.0/build/output //此处为实际的目录

6.安装到指定目录

make install DESTDIR=/home/zlgmcu/Desktop/curl-7.58.0/build/output

至此,libcurl 编译完成

7.完整命令如下(重要)

tar -xvf curl-7.58.0.tar.xz 
cd curl-7.58.0
mkdir build
export PATH=$PATH:/opt/zlg/m1808-sdk-v1.3.1-ga/host/bin  //加载aarch64-linux-gnu目录

../configure --host=aarch64-linux-gnu --prefix=/usr
make
make install DESTDIR=/home/zlgmcu/Desktop/curl-7.58.0/build/output //此处为实际的目录

二、交叉编译七牛云库

1.下载代码到本地

git clone https://github.com/qiniu/c-sdkv

如果网速不好也可以用我们提供的国内镜像

git clone https://gitee.com/cqnews/c-sdk

2.编写Makefile文件

INCLUDE_PATH=-Ibase64 -IcJSON -Iqiniu

SOURCE_FILES=
    b64/b64.c
    b64/urlsafe_b64.c
    cJSON/cJSON.c
    qiniu/auth_mac.c
    qiniu/base.c
    qiniu/base_io.c
    qiniu/cdn.c
    qiniu/conf.c
    qiniu/fop.c
    qiniu/http.c
    qiniu/io.c
    qiniu/macro.h
    qiniu/qetag.c
    qiniu/reader.c
    qiniu/resumable_io.c
    qiniu/rs.c
    qiniu/tm.c


all: $(SOURCE_FILES)

aarch64-linux-gnu-gcc -g -c -fPIC $^ $(INCLUDE_PATH) -lcurl -lcrypto -lssl -lm

3.编译目标文件

make

上面的Makefile是把所有代码编译为.o目标文件

4.使用工具ar打包为静态库

ar rcs libqiniu.a *.o

5.基于.o文件构建动态库

aarch64-linux-gnu-gcc -shared -o libqiniu.so *.o -lcurl -lcrypto -lssl -lm

6.最终得到的构建完毕的发布包
