No joy, I’m afraid. Moreover the support guys at Xamarin say that my code builds for them…
I’m wondering if it’s something to with earlier problems I had - I tried to install an older version of Xcode some time back which cause the machine to Kernel Panic, and while I managed to get things up and running, I was never confident that this old version had been fully removed: there was an instance where the Xamarin studio build was trying to execute a file and because it was still finding the old Xcode version, it was falling over. Deleing this file fixed the problem - I’m wondering if the same might be true for whatever does this “strip” process…
Is there anyone on here more Mac-savvy than me who knows about these sort of things who can advise?
Turns out that my suspicion was correct - the old version of Xcode had left a copy of the strip executable in /usr/bin, and this was getting picked up in preference to the correct version. A few permission changes and a rename later, and we’re building correctly in AppStore configuration.
