错误重新编译探索NFC

Question

虽然重新编译，我们就遇到了这个错误：

的gcc -o basic.c基本$（pkg配置--cflags --libs巧舌如簧-2.0）-I/usr/include目录/ neardal -std = C11

离开这个错误的方式进行了第二次，我们发现了另一个错误， 在neard-explorenfc - 1.2从“编译源”中的操作步骤的README随后一直持续到点“创建配置脚本”。

cmake的-DCMAKE_INSTALL_PREFIX =的/ usr -DCMAKE_INSTALL_SYSCONFDIR = /等。

，我们便无法找到任何解决方案的在线所以我们停留在这个项目的时刻。
任何熟悉或遇到此问题的人？ 在此先感谢！
