Question

在尝试向我的Pi部署代码时，我遇到了问题；

部署到Pi

我从以下link中了解到我没有图书馆。按照该说明，我可以通过调用git clone https://github.com/kgabis/parson.git来安装该库，但是我不遵循的下一条说明是：将parson.h和parson.c复制到your source code tree。

我的问题是在哪里可以找到源代码树，可以在其中找到源目录和其他目录，但是不确定是否是我需要粘贴询问文件的地方？

修改：1
通过修改undefined: json related文件以将CMakeLists.txt文件包含在parson.c and parson.h变量中，可以解决某些问题（SOURCE）
修改了deploy.sh中的命令以包括parson.c and parson.h

我安装libssl-dev

后，与SSL有关的问题就消失了

现在获得以下信息；当我尝试deploy.sh

我尝试了解此 /usr/bin/ld: cannot find -lcurl帖子中提供的答案，但不确定如何使用（对于这些系统，我是相当陌生的）我需要在

中进行更改吗

                          iothub_client

                          ssl
                          crypto)

将代码部署到Raspberry Pi时出错：/ usr / bin / ld：找不到-lcurl
