我想獲得使用flymake在Emacs中工作的C++代碼的語法高亮顯示。我知道，使用C++的標準flymake配置，它會嘗試運行make syntax-check，但是，我的編譯系統不使用Makefile（或至少不是直接）。它使用rosmake這是ROS系統的cmake封裝。Flymake CFGERR使用自定義的g ++命令
爲了解決我無法控制Makefile的問題，我一直試圖添加一個基於flymake website和this stackoverflow question的自定義flymake檢查器。
我創建了命令g++ -Wall -Wextra -fsyntax-only -Iinclude_dir file_to_check.cpp。當我在bash中運行命令時，我得到了預期的輸出。沒有語法錯誤，我有退出碼0和沒有輸出。有了語法錯誤，我有一個退出代碼1和按行列出的錯誤。然而，每當我嘗試用flymake運行時，我會得到一個CFGERR，並被告知flymake已被禁用。
我很確定正確的命令正在運行，因爲錯誤顯示完整的命令，一切看起來都與我在終端中鍵入的內容相同。爲了看看問題是什麼，我將測井等級一直調到3。在日誌中間有一個錯誤

主要錯誤似乎是parsed 'g++: error: : No such file or directory', no line-err-info。我認爲這可能是因爲Broadcaster_flymake.cpp從未創建，但我檢查了它，它似乎工作。無論是否存在語法錯誤，我都會收到這些錯誤。我無法弄清楚爲什麼無法找到該文件，因爲將該命令複製並粘貼到Bash中效果很好。我也嘗試在緩衝區中嘗試(shell-command "g++")，以確保emacs能夠找到g ++二進制文件。
如果你有任何想法，爲什麼flymake無法運行該命令，請讓我知道。謝謝。
