Hi,

This is literally my first day trying to develop on a MAC.

I've spent the last several hours reading through posts for this error message here and on SO but have not been able to resolve this.

I'm running Yosemite 10.10.5

Undefined Symbols For Architecture X86_64 Mac Boost

I have a fresh install of Xcode 7.2

Actually is not system but one of the Cmake command options. As suggested by 'ngladitz' in the 'cmake' channel (irc.freenode.net) I lauched the compile phase with make VERBOSE=1 command and noticed that the compiler used by Make was g-7 (that, in my case, is located in the Homebrew packages installation path) instead of the default Mac OS X C and C compilers that are cc and c. Ezyang changed the title Linker failure on Mac Undefined symbols for architecture x8664: 'testing::internal::UntypedFunctionMockerBase::UntypedInvokeWith(void const.)' on Mac OS X Jun 11, 2019. Ezyang added low priority module: osx labels Jun 11, 2019. This comment has been minimized. ' Undefined symbols for architecture x8664: 'main', referenced from: implicit entry/start for main executable. Ld: symbol(s) not found for architecture x8664. Clang: error: linker command failed with exit code 1 (use -v to see invocation)' Most of the posts I read are for far more complex projects. Hi, I got failed compiling (linking) libsourcey regarding 'Undefined symbols for architecture x8664'. My MAC OS: OS X 10.9.5 The compiling (linking) failed message is as below: Linking C shared library libminizip.dylib Building C object.

I created my first ever project following this tutorial:

After creating the Single View Application I was able to run the simulator.

I then followed the rest of the steps on that page adding UI elements and then when I attempted to run the simulator got the error.

'Undefined symbols for architecture x86_64:

'_main', referenced from:

implicit entry/start for main executable

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)'

Most of the posts I read are for far more complex projects. I did try adding UIKit.framework to the 'Link Binary With Libraries' section of the project Build Phases but got the same error.

I tried reinstalling Xcde (for some reason I have Xcode and Xcode 3 installed)

This SO post seemed to help a number of people but I haven't done any of the things described there. All I did was follow that simple tutorial.

Undefined Symbols For Architecture X86_64 Mac Gcc

Do I need to install something other than Xcode? I thought it included the SDK and all required tools.

Undefined Symbols For Architecture X86_64 Mac Os X

I really don't understand anything about the compiler or the shell commands described as I haven't even got to those tutorials yet...
