无法编译任何C++程序; 错误:未知类型名称'uint8_t'

Question

编辑2:问题不是一个简单的印刷错误.我在下面的日志中写了一个错字,我纠正了,但问题仍然存在.

编辑:在尝试下面之后,我错误地用gcc而不是g ++运行了一次.之前使用g ++存在问题,它现在存在.

我目前正在使用MacOS High Sierra盒子.我最近把很多文件从MacBook Air移到了这台机器上,包括我认为是Xcode的所有垃圾.现在,当我尝试编译一个非常简单的C++程序时:

#include <iostream>

int main()
{
    // VAR_DEC
    int a = 4;
    // VAR_MANIP
    a = a*2;
    // VAR_PRINT
    std::cout << a << std::endl;
    return 0;
}

我得到以下荒谬的错误:

我试过安装和重新安装所有我能想到的相关的问题,如gcc,g++,cc,brew,Xcode的,command-line-tools等我也试着在下面几页的所有建议:

• 未知的类型名称uint8_t？
• 在Mac OS X Yosemite 10.10.1上包含搜索路径
• 由于未知类型名称'uint64_t',Cythonizing失败
• 未知类型名称'uint8_t',MinGW
• JT Bullitt非常全面的博客

还有更多,但那些总结得很好.这些解决方案都没有奏效.

我认为最后一个有最可能的解决方案.(如果您在页面上搜索"未知",您将看到修复.)根据开发人员的说法:

修复:从"标题搜索路径"构建设置中删除/ opt/local/include/**和/ opt/local/lib/**.用更具体的路径替换它们到所需的包含目录.在我的特定情况下,这意味着用/opt/local/include/glib-2.0 /opt/local/lib/glib-2.0/include/opt/local/include /替换它们.它再次启动并运行!

但是,我没有安装Xcode,我只安装了命令行开发工具.因此,我没有一种简单的方法来访问"Header Search Paths"构建设置,因此,我无法尝试他的解决方案.

我正在寻找这个问题的解决方案,最好不要求我安装整个操作系统.或者,如果有人可以指导我找到构建设置文件,我将非常感激.

Answer 1

也许你可以尝试:

mv /usr/local/include /usr/local/include.old

然后:

brew install llvm

Answer 2

很明显，您破坏了系统 GCC 安装。请注意，GCC 是一套编译器，而G++是 C++ 前端。包管理器通常有一个名为 的单独包gcc-g++，但是，从源代码编译时，您只需这样做--enable-languages=c,c++。现在，如果重新安装 XCode 不能解决问题（您应该已经这样做了，如果“它占用太多空间”只需将其删除），那么您可以尝试从源代码编译 GCC。改编自GNU wiki：

• 首先，从这里获取您想要的 GCC 焦油球

• 解压它tar zxvf gcc*

• cd gcc*然后./contrib/download_prerequisites

• 进行源外构建：mkdir build && cd build

• ../gcc*/configure --prefix=$HOME/gcc-install --enable-languages=c,c++

• make和make install

现在只需添加$HOME/gcc-install/bin到您的路径中，您就可以开始了。
