| Description | It seems that with macOS 10.14 and beyond, Apple is deprecating the use of /usr/include and instead puts the corresponding files in the os-version-specific SDK directories: https://developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes#3035623
(note that xcode-select --install does not fix this)
This breaks OpenSSL and Python with the errors shown in Additional Information below. Probably other things break too.
A workaround is setting the SDKROOT, like this, which allows the build to succeed:
SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk make -j20
We should find a way to send the correct SDKROOT to the SuperBuild dependencies, e.g. via cmake as a byproduct of setting the CMAKE_OSX_DEPLOYMENT_TARGET. |
