Ubuntu下使用CMake编译OpenSSL源码操作步骤(C语言)

OpenSSL的版本为1.0.1g，在ubuntu下通过CMake仅编译c代码不包括汇编代码，脚本内容如下：

build.sh内容：

#! /bin/bash
    
    real_path=$(realpath $0)
    dir_name=`dirname "${real_path}"`
    echo "real_path: ${real_path}, dir_name: ${dir_name}"
    
    new_dir_name=${dir_name}/build
    mkdir -p ${new_dir_name}
    cd ${new_dir_name}
    echo "pos: ${new_dir_name}"
    if [ "$(ls -A ${new_dir_name})" ]; then
    	echo "directory is not empty: ${new_dir_name}"
    	#rm -r *
    else
    	echo "directory is empty: ${new_dir_name}"
    fi
    
    cd -
    # build libcurl
    echo "========== start build libcurl =========="
    libcurl_path=${dir_name}/../../src/curl
    if [ -f ${curl_path}/build/lib/libcurl.so ]; then
    	echo "libcurl dynamic library already exists without recompiling"
    else
    	mkdir -p ${libcurl_path}/build
    	cd ${libcurl_path}/build
    	cmake  -DBUILD_SHARED_LIBS=ON ..
    	make
    fi
    
    ln -s ${libcurl_path}/build/lib/libcurl* ${new_dir_name}
    echo "========== finish build libcurl =========="
    
    rc=$?
    if [[ ${rc} != 0 ]]; then
    	echo "########## Error: some of thess commands have errors above, please check"
    	exit ${rc}
    fi
    
    cd -
    cd ${new_dir_name}
    cmake ..
    make
    
    cd -
