Generation Error

[SilkSong]

Hi there,
I encountered a generation error when following the steps.
CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: IOMP5LIB linked by target "TestOMP" in directory /Users/Song/Developer/cmake-xcode-openmp
Configuration can be done correct. I think I have followed the steps correctly.
Really appreciate if you can solve the error.

Thanks in advance

Hello Zixin! From the error message, it seems CMake is asking for the IOMP5LIB, which is the core of OpenMP that you may find here: https://mac.r-project.org/openmp/ Link that library and it should work.

This is one of the step you mentioned in the readme. I think I have followed it before. And I just did it once again but the error is still there. I got the same verification result as the webpage. Is there anything I did wrong?

[nepluno]

So you have set the variable IOMP5LIB in CMake to this path (/usr/local/lib/libomp.dylib) and there's still the error?

[SilkSong]

Sorry that I am not sure which step is related with "set the variable IOMP5LIB in CMake to the path". Basically, I just followed all the steps in the readme including this webpage https://mac.r-project.org/openmp/. It can configure without error but generate with error just like above.

[nepluno]

You can type the path of libomp.dylib into the "value" column of the line with name IOMP5LIB.

Thank you for the timely reply. It built without error! I can see the C++ project on Xcode. I need to write in C. I tried to add a C file to the project. Both the C++ and C file can be built without error but I can't run them. Both the Run button on menu bar and Cmd + R did not work.
Tbh, I am really a beginner on C/C++ programming. Can I just do sth to make it run ? or I need to learn more first then figure out how to run it by myself.

many thanks

You can choose which executable to run in the Product -> Scheme menu. There might be multiple projects but one of them should be a runnable executable.
