--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Iain D Sandoe <ia...@gcc.gnu.org>: https://gcc.gnu.org/g:bec7100445f07259d5df69c9f442ea72a90fc37e commit r14-8733-gbec7100445f07259d5df69c9f442ea72a90fc37e Author: Iain Sandoe <i...@sandoe.co.uk> Date: Wed Jan 24 08:05:41 2024 +0000 testsuite, Objective-C++: Update link flags [PR112863]. These regressions are caused by missing or duplicate runpaths which now fire linker warnings. We need to add options to locate libobjc (and on Darwin libobjc-gnu) along with libstdc++. Usually '-L' options are added to point to the relevant directories for the uninstalled libraries. In cases where libraries are available as both shared and convenience some additional checks are made. For some targets -static-xxxx options are handled by specs substitution and need a '-B' option rather than '-L'. For Darwin, when embedded runpaths are in use (the default for all versions after macOS 10.11), '-B' is also needed to provide the runpath. When '-B' is used, this results in a '-L' for each path that exists (so that appending a '-L' as well is a needless duplicate). There are also cases where tools warn for duplicates, leading to spurious fails. PR target/112863 gcc/testsuite/ChangeLog: * lib/obj-c++.exp: Decide on whether to present -B or -L to reference the paths to uninstalled libobjc/libobjc-gnu and libstdc++ and use that to generate the link flags.
