https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104871 --- Comment #4 from CVS Commits --- The releases/gcc-11 branch has been updated by Iain D Sandoe : https://gcc.gnu.org/g:3417f095f149ba09ca9d4f62bfaf661819a04333 commit r11-10782-g3417f095f149ba09ca9d4f62bfaf661819a04333 Author: Simon Wright Date: Sun Jun 12 17:01:22 2022 +0100 Darwin: Truncate kernel-provided version to OS major for Darwin >= 20. In common with system tools, GCC uses a version obtained from the kernel as the prevailing macOS target, when that is not overridden by command line or environment versions (i.e. mmacosx-version-min=, MACOSX_DEPLOYMENT_TARGET). Presently, GCC assumes that if the OS version is >= 20, the value used should include both major and minium version identifiers. However the system tools (for those versions) truncate the value to the major version - this leads to link errors when combining objects built with clang and GCC for example: ld: warning: object file (null.o) was built for newer macOS version (12.2) than being linked (12.0) The change here truncates the values GCC uses to the major version. gcc/ChangeLog: PR target/104871 * config/darwin-driver.c (darwin_find_version_from_kernel): If the OS version is darwin20 (macOS 11) or greater, truncate the version to the major number. (cherry picked from commit add1adaa17a294ea25918ffb4fdd40f115362632)
