#49613: root6 upgrade fails -------------------------------+-------------------------------- Reporter: david.w.watson@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: root6 | -------------------------------+-------------------------------- Comment (by jonesc@…): Do you have one of the MacPorts gcc ports 'port selected' to make it your default 'gcc' ? If so this appears to be the problem, as it appears the internal build of GSL, which I switched to for this version due to the fact ROOT does not yet support GSL 2.0 which MacPorts now uses, and during configure the internal GSL is discovering your gcc version and this is causing problems. The work around is please un-select MacPorts gcc version, upgrade ROOT, then select it again. I was able to reproduce your failure by port selecting myself, and un-selecting it fixes things. This is a bug in ROOT's build system, as it should configure its internal GSL version to build using the same compiler settings as ROOT itself. Please file this as a bug against ROOT upstream, as it is not a bug in the MacPorts port. I am hoping the next release will contain support for GSL 2.0, in which case I can revert back to using MacPorts version.
