Cannot compile any C++ programs; error: unknown type name 'uint8_t'

Question

EDIT2: The problem was NOT a simple typographical error. I made a typo in the logs below, which I corrected, but the problem was still there.

EDIT: I mistakenly ran with gcc instead of g++, once, after attempting below. The problem was there before with g++ and it is there now.

I am currently on a MacOS High Sierra box. I recently moved a lot of files from a MacBook Air to this machine, including what I assume were all of Xcode's junk. Now, when I try to compile a very simple C++ program:

#include <iostream>

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

I get the following ridiculous error:

I've tried installing and reinstalling everything I could think of related to the problem, such as gcc, g++, cc, brew, Xcode, command-line-tools, etc. I've also tried all the suggestions on the following pages:

• Unknown type name uint8_t?
• Include search path on Mac OS X Yosemite 10.10.1
• Cythonizing fails because of unknown type name 'uint64_t'
• unknown type name 'uint8_t', MinGW
• JT Bullitt's very comprehensive blog

and more, but those summarize it pretty well. None of the solutions have worked.

I think the last one has the most likely solution. (If you search for "unknown" on the page you'll see the fix.) According to the developer:

Fix: Remove /opt/local/include/** and /opt/local/lib/** from the "Header Search Paths" build settings. Replace them with much more specific paths to the desired include directories. In my particular case, this meant replacing them with /opt/local/include/glib-2.0 /opt/local/lib/glib-2.0/include /opt/local/include/. It's up and running again!

However, I didn't install Xcode, I only installed the command line developer tools. Therefore, I don't have an easy way to access the "Header Search Paths" build settings, and thus, I can't try out his solution.

I am looking for a solution to this problem, preferably one that doesn't require me installing the entire OS. Alternatively, if someone could kindly guide me through finding the build settings file, I would be very grateful.

Answer 1

Maybe you can try:

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

then:

brew install llvm
