錯誤重新編譯探索NFC

Question

雖然重新編譯，我們就遇到了這個錯誤：

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

離開這個錯誤的方式進行了第二次，我們發現了另一個錯誤， 在neard-explorenfc - 1.2從「編譯源」中的操作步驟的README隨後一直持續到點「創建配置腳本」。

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

，我們便無法找到任何解決方案的在線所以我們停留在這個項目的時刻。
任何熟悉或遇到此問題的人？ 在此先感謝！
