Clion doesnt compile on MacOS Sierra

Hi Alimaj.

Please re-install Xcode developer tools via 

xcode-select --install

in terminal.

Hello!

Thanks a lot Anna Filippova.

I have been struggling with that error for about 1 week. Now it is working.

Best regards,

Roger

Hello!

I've got the same problems with Alimaj's after upgrading MacOS X to Sierra.

But it didn't help to try the command that Anna provided. The error is still the same as below, anyone can help?

/Applications/CLion.app/Contents/bin/cmake/bin/cmake -DCMAKE_BUILD_TYPE=Debug -G "CodeBlocks - Unix Makefiles" /Users/zhiyuanwang/ClionProjects/test

 It fails with the following output:

I had the same problem. For me, the fix was to agree to the xcode license. To do that, open up a terminal and enter the following command:

sudo xcodebuild -license

Once you've entered your sudo password the license will then be presented on screen, hit the space bar to scroll through the text. When you get to the end of the text, you'll be prompted to enter 'agree', type this in, and then, back in CLion, click on File->Reload CMake Project and everything should work. 

Good luck.

Cheers

Barry

I had the same problem, and it worked only after I did both steps.
Thank you very much Anna and Barry.

This also solves the problem where you can make the project from the command line, but CLion cant with this error 

/Library/Developer/CommandLineTools/usr/bin/c++: Permission denied clion

Thank you Barry

Hi. My issue is after I remove Xcode. But I still do have Command Line Tools, which include all the necessary compilers such as clang, gcc. The error that I read is the following:

/Applications/CLion.app/Contents/bin/cmake/bin/cmake --build /Users/hsl/CLionProjects/Test_sololearn/cmake-build-debug --target untitled -- -j 2
Scanning dependencies of target untitled

make[2]: *** [CMakeFiles/untitled.dir/all] Error 2

I would appreciate some help.

Hi 

what solved the problem for me was to install & open XCODE, and afterwards to agree to software requirements. 

Apparently XCODE makes some difference on macOS for C & C++ programming... 

So many thank for Anna and Barry, I solved this problem by completing both steps, just one tip, when terminal ask you to enter the sudo password, that's the password you used to open your Macbook
