I made sure my mac is updated and I can build current git master just fine!

$ sw_vers

I think I might have xcode 9.1:

@koshak01 what version of xcode

[koshak01]

➜ ~ /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -version
Xcode 9.1
Build version 9B55

There is a fix in 870d849 that was added for xcode 9 so I'm stumped as to why you're seeing that. Did you forget to run buildconf after you checked out the latest release by chance?

/cc @nickzman

[bagder]

FYI: That's the exact same version of xcode that I have installed.

[koshak01]

I run buildconf after - but this not help ;(

Before i have xcode version 8.3.3 - and i see same problem.
upgrade xcode not solve problem.

Now this struck me. I don't have any /usr/include directory at all so clearly something is different between our installations! Well, except that you also seem to genuinely use gcc which also doesn't seem very xcode.

I believe the socket.h header my compiler uses is either /Applications/Xcode.app/Contents//Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/sys/socket.h or /Applications/Xcode.app/Contents//Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/sys/socket.h

I wonder if you have some old command line tools or headers installed that are getting in the way. You can force Xcode to install the appropriate tools & headers for your macOS release by running "xcodeselect --install" in Terminal.

Also, if you're using macOS 10.13.x, you should uninstall Xcode 8. Old versions of Xcode generally don't work in newer macOS releases, and I can't think of any reason to keep Xcode 8 around in 10.13 anyway.
