I discovered, by installing the Sage_macOS app on a pristine macOS system, that somehow, somewhere, in Sage's startup sequence there is a call to gcc. This is true whether Sage is being started from a command line or a notebook.
On such a macOS system /usr/bin/gcc exists, but calling it causes a dialog to be posted which asks whether to download and install the Xcode "command line tools". There is no need for a user to install, or be prompted to install, a C compiler in order to run Sage. If we want to verify whether a C compiler is installed on the host system then we should check the return value of xcode-select -p rather than calling /usr/bin/gcc. I am unable to find where this call occurs. Do any of the Sage developers know which component of Sage could be calling /usr/bin/gcc on start up? - Marc -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
