Revision 197a772c48652d94ddb340fc6bcd8ed4440ff233 authored by Johannes Schindelin on 20 May 2024, 20:22:01 UTC, committed by Junio C Hamano on 21 May 2024, 19:33:08 UTC
In df93e407f06 (init: refactor the template directory discovery into its own function, 2024-03-29), I refactored the way the templates directory is discovered. The refactoring was faithful, but missed a reference in the `Makefile` where the `DEFAULT_GIT_TEMPLATE_DIR` constant is defined. As a consequence, Git v2.45.1 and friends will always use the hard-coded path `/usr/share/git-core/templates`. Let's fix that by defining the `DEFAULT_GIT_TEMPLATE_DIR` when building `setup.o`, where that constant is actually used.
