From d47e3aed12414be59bf77177c93853ec4b24d705 Mon Sep 17 00:00:00 2001 From: Fabrice Fontaine Date: Sat, 2 Jun 2018 16:53:36 +0200 Subject: [PATCH] disable shared library target in build Disable shared library target if BUILD_SHARED_LIBS if OFF. Patch retrieved from https://git.buildroot.net/buildroot/tree/package/librtlsdr/0001-disable_shared_library_target_in_build.patch?h=2018.05 Patch has been updated to work with 0.5.4 and to be able to keep current behavior of building shared and static version of library if BUILD_SHARED_LIBS and BUILD_STATIC_LIBS are both set. Moreover, if BUILD_STATIC_LIBS is OFF, only shared version of library will be install.
