问题描述
我刚刚更新到Sierra,看来我的编译器由于某种原因而崩溃了。
I just updated to Sierra and it seems my compiler fell apart for some reason.
我在更新之前编写的代码运行良好,所以我确定那里不是问题,但是现在当我尝试执行它时,它什么也没用。
The code I wrote worked fine before the update, so I'm sure its not an issue there but now it just isn't working what so ever when I try to execute it.
这里是输出。
$ g++ source.cpp
$ ./a.out
dyld: mach-o, but built for simulator (not macOS)
Abort trap: 6
运行G ++并带有@NulledPointer的详细信息

推荐答案
有多种选择:
- 尝试使用
xcode-select --install
安装缺少的工具(如果有),然后尝试编译。如果失败,则 - 尝试运行
gcc -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11 .sdk source.cpp
。显然,这是假设您在该位置安装了SDK。替换为存在的任何位置。
- Try installing missing tools (if any) using
xcode-select --install
and try compiling. If that fails, - Try running
gcc -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk source.cpp
. This obviously assuming you have SDK installed in that location. Replace with whatever location exist there.
