我正在开发一个使用boost asio的C项目.尝试构建使用亚洲的库,我收到以下错误
/usr/local/include/boost/asio/ssl/detail/openssl_types.hpp:19:10: fatal error: 'openssl/conf.h' file not found #include <openssl/conf.h>
brew install openssl brew link openssl --force xcode-select --install
但没有帮助.
执行以下操作似乎也不起作用
export C_INCLUDE_PATH=/usr/local/include export CPLUS_INCLUDE_PATH=/usr/local/include
我正在使用的Boost版本是boost_1_63_0.我在Mac OS Sierra上使用Xcode 8.3.1.我使用Homebrew安装了boost
brew install boost
据我所知,从其他链接来看,Xcode正在寻找ssl头的错误位置.
但是我怎么解决这个问题呢？
我查看了我的/usr/local/include& /选择/本地/包括.两个地方都没有’openssl / ssl.h’.但是做一个brew安装openssl说如下
Warning: openssl is a keg-only and another version is linked to opt. Use `brew install --force` if you want to install this version
做一个brew安装openssl –force说
Warning: openssl-1.0.2k already installed,it's just not linked.
使用brew链接openssl –force也无法解决问题.
Doig a openssl返回以下内容：
/usr/local/bin/openssl
请建议
解决方法
是否链接,可以通过/usr/local/opt中的链接访问所有已安装的Homebrew软件包.此外,当您通过Homebrew安装openssl时,Homebrew会告诉您如何使用openssl库和标头.
