如何在Emacs Lisp中獲取C / C ++標頭系統包含目錄？

Question

如何在emacs lisp中獲取c / c ++頭文件系統的include目錄？

就像“ gcc -xc ++ -E -v-”的輸出部分一樣

/usr/include/c++/4.8
/usr/include/x86_64-linux-gnu/c++/4.8
/usr/include/c++/4.8/backward
/usr/lib/gcc/x86_64-linux-gnu/4.8/include
/usr/local/include
/usr/lib/gcc/x86_64-linux-gnu/4.8/include-fixed
/usr/include/x86_64-linux-gnu
/usr/include

Answer 1

CEDET具有semantic-gcc-get-include-paths函數，該函數返回C或C ++語言的路徑...

Answer 2

除了亞歷克斯的答案，我還要提及：

調用semantic-gcc-setup后， (semantic-gcc-get-include-paths "c")和(semantic-gcc-get-include-paths "c++")值存儲在局部緩沖區變量中semantic-dependency-system-include-path 。
