* [PATCH] gdb: Fix GDB_AC_CHECK_BFD macro regression @ 2023-03-07 14:21 Richard Purdie 2023-03-07 14:25 ` Simon Marchi 0 siblings, 1 reply; 4+ messages in thread From: Richard Purdie @ 2023-03-07 14:21 UTC (permalink / raw) To: gdb-patches; +Cc: Jose E . Marchesi, Simon Marchi Commit 5218fa9e8937b007d554f1e01c2e4ecdb9b7e271, "gdb: use libtool in GDB_AC_CHECK_BFD" dropped passing in existing LDFLAGS. In our environment, this caused the configure check "checking for ELF support in BFD" to stop working causing build failures as we need our LDFLAGS to be used for correct linking. That change also meant the code failed to match the comments. Add back the missing LDFLAGS preservation, fix our builds and match the comment.

Running autoreconf, I see one more hunk in configure.
