我正在尝试交叉编译openvpn 2.3.4和polarssl 1.3.7，用于debian wheezy上的arm。polarssl已编译并安装在我的主目录中，但openvpn找不到库和头，因此显示以下错误消息：
checking polarssl version... configure: error: PolarSSL 1.2.x required and must be 1.2.10 or later
Polarssl的配置如下：
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_SYSTEM_NAME=Linux -D CMAKE_C_COMPILER=arm-linux-gnueabihf-gcc -D CMAKE_INSTALL_PREFIX=/home/smith9073/polarssl -D ENABLE_PROGRAMS=OFF ../polarssl-1.3.7/
这就是我试图告诉openvpn关于polarssl位置的方法：
CFLAGS="-I/home/smith9073/polarssl/include" LDFLAGS="-L/home/smith9073/polarssl/lib" ./configure --host=arm-linux-gnueabihf --with-crypto-library=polarssl

有人知道为什么openvpn找不到polarssl吗？
最佳答案
polarssl 1.3.x版本破坏了1.2.x系列的api，openvpn还没有更新到新的api，因此暂时您必须使用polarssl1.2.x或其他加密后端（openssl）。
