However, with 10.15 there is a fundamental shift compared to all previous OS-X versions: the root filesystem (/) is read-only and will NOT allow /sw to be created. My testing thus far has used ~/sw, which is less than ideal (e.g., no bindist). My question is: is it possible to get Apple to create a ‘firmlink’ so that /sw is read-write? Has anyone come up with a more clever solution? Hoping I can help further the cause with 10.15…

Sorry to hear that Hanspeter,

You may be able to work with /sw, or /sw2, by disabling SIP and then executing ’sudo mount -uw /‘. However, the mount command would have to be repeated after each reboot, and ultimately may not work at all. Hence the recommendation to migrate to /opt/sw, which I’m glad to hear is working…

After fixing my mistake regarding ‘xcodebuild -license’ I still find that gmp5, as well as gcc8, will not compile with Xcode 11b6. I succeeded building those packages by reinstalling Xcode 10.3 into /Applications, and executing ‘sudo xcode-select -s /Applications/Xcode.app’. However, in order to compile python27 I had to switch back to Xcode 11b6 via ‘xcode-select -s /Applications/Xcode-beta.app’. At least reverting to Xcode 10.3 allows progress to be made, until the offending packages can be patched to work under Xcode 11. I hope that will also work for you!

Cheers,
John
