Compiling with XCode 9.2 (9C40b) - float.h filenot found

I try to build Audacity with Mac Os 10.13.3 and Xcode Version 9.2 (9C40b).
I follow the instructions in order to use the old SDK but in the end I have now issue with finding float.h.
How can I fix it ?


  1. Download Xcode 8.1 and install it to /Applications.

Ok I’ll try with the old version of XCode . I will write here if I will succeed :wink:

Can anyone confirm that switching to Xcode 8.1 will fix this error?

I can confirm that Audacity build will fail if you use the wrong version of XCode.

I confirm that after switching to Xcode 8.1, the wxWidget_audacity_fixes project builds successfully.
