使用MacOS Mojave的Code :: Blocks C ++编译:致命错误:sys/cdefs.h:没有这样的文件或目录 [英] Code::Blocks C++ compiling with MacOS Mojave : fatal error: sys/cdefs.h: No such file or directory

问题描述

(这是我有关StackOverflow的第一个问题)

(This is my first question ever on StackOverflow)

我必须在工作中使用Mac，并且我正在使用Code :: Blocks进行C ++编码(因为我已经习惯了此IDE). 2天前，我从MacOS High Sierra升级到了MacOS Mojave，我可以说...这是一个错误的决定.

I have to use a Mac at work, and I'm coding in C++ with Code::Blocks (because I am used to this IDE). 2 days ago I upgraded from MacOS High Sierra to MacOS Mojave and I can fairly say that... it was a bad decision.

现在，当尝试使用#include <math.h>时，出现此错误:fatal error: sys/cdefs.h: No such file or directory.我试图用xcode-select --install重新安装xcode行命令工具，但仍然无法正常工作.

Now, when trying to #include <math.h> I get this error : fatal error: sys/cdefs.h: No such file or directory. I have tried to reinstall the xcode line command tools with xcode-select --install, but it still doesn't work.

有人知道发生了什么，如何解决这个问题?

Does anybody have a clue of what is going on, and how I could solve this issue ?

推荐答案

通过重新安装gcc解决了问题.标头的位置可能在High Sierra和Mojave之间发生了变化.

Problem solved by reinstalling gcc. Location of headers has probably changed between High Sierra and Mojave.

我建议遇到相同问题的任何人都要做同样的事情，并且还建议使用xcode-select --install

I suggest to anyone encountering the same problem to do the same and also to (re)install the xcode line command tools with xcode-select --install
