It may be worth running the following command first if you already have an existing homebrew installation: brew info llvm Simply run this command: brew install -with-toolchain llvm Using Homebrew, we can install llvm/clang very easily. I use Homebrew to manage extra packages, and I highly recommend it. The manual compile+install instructions are also applicable for those not using OS X. If you would like to go the manual compile+install route, please check this guide from the LLVM group. Using mainline clang on my system proved to take a little more work than I expected, so I hope my notes make setup easier for you. However, I have encountered many cases where using the Apple clang compiler has resulted in odd behavior or unexpected errors after updating Xcode.Īs a result, I recommend using the mainline clang for your embedded development. You can even get the iPhone SDK to work well enough for embedded development using ARM. These tools work well when compiling for your host machine. I can easily imagine that the problem with my machine more generally and not a problem with psutil specifically, but I have not previously come across this error before and have been unable to find anything about similar issues online.If you are a developer using clang or gcc on OS X, the odds are good that you are using the Xcode build tools. Developer/SDKs/MacOSX10.6.sdk/usr/include/float.h:8:15: fatal error: 'float.h' file not foundĮrror: command '/usr/bin/clang' failed with exit status 1Īs best I can tell, both float.h files that are found have #include_next statements, and after this it cannot find the file in the search path.

I am getting the following installation error when attempting to install psutil with pip on macOS 10.12.6.
