From: Michael Pratt Date: Sat, 18 May 2024 01:23:33 +0000 (-0400) Subject: tools/elfutils: use conditional to block build of shared objects X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9670a38d08c1d842f16ef7811080808f2c147898;p=openwrt%2Fstaging%2Fthess.git tools/elfutils: use conditional to block build of shared objects Add a potentially upstream-friendly conditional using the libtool configure variable "enable_shared" in order to block building and installing of shared objects and adjust the build of static libraries instead of directly patching lines in or out.
