c++ - 编译源代码时出现 cURLcpp 错误

Question

我对 C++ 和 github 的使用有点陌生。我想在 C++ 中使用 cURL 功能。因此，我首先从 github 中 fork curlcpp(由 JosephP91 编写)，然后按照其 README.txt 中的说明进行操作。

现在执行时出现错误

make # -j2

(有或没有 -j2 没有区别)。

错误:

[ 12%] Building CXX object src/CMakeFiles/curlcpp.dir/curl_easy.cpp.o
In file included from /home/user/.git/curlcpp/src/curl_easy.cpp:6:0:

在此先感谢大家对我的帮助!

您需要在 Ubuntu 上将 libcurl 从版本 7.35.0 更新到 7.37.1，在 utopic 存储库 (http://packages.ubuntu.com/utopic/libcurl4-nss-dev) 上可以使用 libcurl 7.31。

您可以使用 apt-get 进行更新:

echo "deb http://archive.ubuntu.com/ubuntu/ utopic main restricted" | sudo tee /etc/apt/sources.list
apt-get update
apt-get upgrade libcurl4-nss-dev

然后重做 cmake 和 make，它应该可以正常编译。
