Hi,
I have a strange behaviour with the latest version of catalina/xcode/macport : SDK 10.15 is installed, but mac port doesn't find it... here are some logs: $ sudo port upgrade outdated Password: Warning: The macOS 10.15 SDK does not appear to be installed. Ports may not build correctly. Warning: You can install it as part of the Xcode Command Line Tools package by running `xcode-select --install'. ... $ xcode-select --install xcode-select: error: command line tools are already installed, use "Software Update" to install updates $ softwareupdate --list Software Update Tool Finding available software No new software available. $ xcrun --sdk macosx10.15 --show-sdk-path /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk here is my current configuration: macport version: 2.6.2 osx version: catalina 10.15.4 xcode version: 11.5 (11E608c) Any idea would be more than welcome.
