Do you have any > specific make.conf or src.conf settings for that? I got bitten by this recently. In my case, it was Poudriere (running on = 14-CURRENT) trying to build a 13-STABLE jail. The Poudriere jail's = "src.conf" was taken from the actual system for which Poudriere builds = packages. It had (amongst others) these two options: WITH_SYSTEM_COMPILER=3Dyes WITHOUT_CROSS_COMPILER=3Dyes When I commented these out in the jail-src.conf Poudriere file the jail = built correctly. I figure the system built fine because its system compiler is LLVM 14.x. = The Poudriere system compiler is LLVM 15.x, which has the breaking = change wrt. old-style prototypes. Cheers, Paul.=
