arm交叉编译openssl和curl

环境：Ubuntu14.04.1 64位

已经安装并配置arm-poky-linux交叉编译器

arm板为IMX6的板子

openssl版本：openssl-OpenSSL_1_0_2r.tar.gz(试过使用1.1的版本，不过报错，编译不过)

解压并进入openssl-OpenSSL_1_0_2r，可以先看一下官方的安装说明INSTALL

打开控制台，先执行交叉编译器环境设置

source /opt/fsl-imx-fb/qt5/environment-setup-cortexa9hf-neon-poky-linux-gnueabi

 

然后执行如下命令，测试环境变量是否设置成功，获取交叉编译器arm-poky-linux-gnueabi-gcc的版本号

 

$CC -v

source命令设置的环境只在当前打开的控制台有效。

开始编译openssl

# 进入openssl-OpenSSL_1_0_2r
cd openssl-OpenSSL_1_0_2r
# 配置并生成Makefile
./config no-asm --prefix=~/arm/openssl

直接make会报错

需要手动修改Makefile文件，将CC= $(CROSS_COMPILE)arm-poky-linux-gnueabi-gcc 修改为 CC= arm-poky-linux-gnueabi-gcc

还要将文件中两处-m64删除，否则报错如下：

arm-poky-linux-gnueabi-gcc: error: unrecognized command line option '-m64'
make[1]: *** [cryptlib.o] 错误 1

#编译并安装
make
make install

完成后就可以在/home/你用户名/arm/openssl中看到生成的头文件和库文件

编译curl

curl版本：curl-7.64.0.tar.gz

解压，官方安装说明在curl-7.64.0/docs/INSTALL.md

# 配置并生成Makefile
./configure --host=arm-none-linux --prefix=~/arm/curl --with-ssl=~/arm/openssl
# 编译
make
# 安装
make install

到此就安装完成了

在开始的时候直接使用命令source /opt/fsl-imx-fb/qt5/environment-setup-cortexa9hf-neon-poky-linux-gnueabi配置好交叉编译器环境，可以看一下environment-setup-cortexa9hf-neon-poky-linux-gnueabi这个文件，然后可以参考并修改这个文件内容手动配置其他交叉编译器环境

在curl的安装说明中对交叉编译有如下，对比两个文件，可以对其他交叉编译器进行类似的设置

# Cross compile

Download and unpack the curl package.

'cd' to the new directory. (e.g. `cd curl-7.12.3`)

Set environment variables to point to the cross-compile toolchain and call
configure with any options you need.  Be sure and specify the `--host` and
`--build` parameters at configuration time.  The following script is an
example of cross-compiling for the IBM 405GP PowerPC processor using the
toolchain from MonteVista for Hardhat Linux.

    #! /bin/sh

    export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin
    export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include"
    export AR=ppc_405-ar
    export AS=ppc_405-as
    export LD=ppc_405-ld
    export RANLIB=ppc_405-ranlib
    export CC=ppc_405-gcc
    export NM=ppc_405-nm

    ./configure --target=powerpc-hardhat-linux
        --host=powerpc-hardhat-linux
        --build=i586-pc-linux-gnu
        --prefix=/opt/hardhat/devkit/ppc/405/target/usr/local
        --exec-prefix=/usr/local

编译的时候参考了如下几篇博客：
