linux环境编译 c语言版sdk提示ssl错误

ssl库编译具体什么错误啊

-------------------------

你的OPENSSL可以编译过吗

-------------------------

curl发送的时候要调用openssl的路径吧，所以需要设置路径；

我在ubuntu环境编译 linux  平台 c语言版sdk, 到最后编译 阿里云sdk时，总是提示 ssl的库文件错误。
就是参考 README.md文件来编译的。

-------------------------

编译的sdk版本是 aliyun-oss-c-sdk-3.4.3.tar.gz

依赖库版本分别是:
apr-1.5.2.tar.gz
apr-util-1.5.4.tar.gz
curl-7.34.0.tar.gz
mxml-2.9.tar.gz
openssl-1.0.1e.tar.gz
perl-5.16.3.tar.gz

-------------------------

(1) curl-7.34.0(官方建议7.32.0及以上版本)
http://curl.haxx.se/download.html

cd /home/oss_sdk_test/curl-7.34.0 \
&& ./configure --with-ssl --with-libssl-prefix=/usr/local/ssl && make
&& make install

(2) apr-1.5.2(官方建议1.5.2及以上版本)
https://apr.apache.org/download.cgi

cd /home/oss_sdk_test/apr-1.5.2 && ./configure && make
&& make install

(3) apr-util-1.5.4(官方建议1.5.4及以上版本)
https://apr.apache.org/download.cgi

cd /home/oss_sdk_test/apr-util-1.5.4 \
&& ./configure --with-apr=/usr/local/apr/ && make
&& make install

(4) mxml-2.9(官方建议2.8及以上版本)
http://www.msweet.org/downloads.php?L+Z3

cd /home/oss_sdk_test/mxml-2.9 && ./configure
&& make
&& make install

(5) 编译OSS C SDK
https://help.aliyun.com/document_detail/32175.html

cd /home/oss_sdk_test/aliyun-oss-c-sdk-3.4.3

cmake . -DCURL_INCLUDE_DIR=/usr/local/include/curl/ -DCURL_LIBRARY=/usr/local/lib/libcurl.a \
-DAPR_INCLUDE_DIR=/usr/local/include/apr-1/ -DAPR_LIBRARY=/usr/local/apr/lib/libapr-1.a \
-DAPR_UTIL_INCLUDE_DIR=/usr/local/apr/include/apr-1 -DAPR_UTIL_LIBRARY=/usr/local/apr/lib/libaprutil-1.a \
-DMINIXML_INCLUDE_DIR=/usr/local/include -DMINIXML_LIBRARY=/usr/local/lib/libmxml.a

make

编译出现错误如下:

-------------------------

参考sdk源码里的 README.md文件，在 64位 ubuntu环境编译的。

-------------------------

帮助文档中，没有看到执行cmake命令时，设置openssl头文件和库文件的定义。

-------------------------

openssl 可以编译通过，
编译crul 的时候，需要打开ssl 么？

-------------------------

只在编译curl的时候，设置 openssl的路径么？
后面编译 OSS C SDK时，不用再设置 openssl 的 sdk路径么 ？
