From: Jon Turney <jturney@sourceware.org> To: cygwin-cvs@sourceware.org, newlib-cvs@sourceware.org Subject: [newlib-cygwin/cygwin-3_4-branch] Cygwin: dumper: also link with libzstd, as libbfd may require it Date: Tue, 14 Feb 2023 22:05:26 +0000 (GMT) [thread overview] Message-ID: <20230214220526.F2DE53858C30@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=2fd459c3b180def80b0db4b6c91e4f088e779cc1 commit 2fd459c3b180def80b0db4b6c91e4f088e779cc1 Author: Jon Turney <jon.turney@dronecode.org.uk> Date: Tue Feb 14 13:52:39 2023 +0000 Cygwin: dumper: also link with libzstd, as libbfd may require it Also allow that linkage to be dynamic, as libzstd-devel doesn't currently provide a static library.
