Module: kamailio Branch: master Commit: bca9768b6f2667bad8472fa99a113b8249ca0f9a URL: https://github.com/kamailio/kamailio/commit/bca9768b6f2667bad8472fa99a113b8… Author: Greg Troxel <gdt(a)lexort.com> Committer: Greg Troxel <gdt(a)lexort.com> Date: 2020-03-18T19:06:36-04:00 Makefile.defs: Only add -ldl on systems that use it kamailio uses dlopen, and on some systems, one must link with -ldl. On others, this is not needed and there is no libdl. For now, simply omit -ldl on NetBSD (which doesn't have or require it), and don't try to change behavior on other systems. --- Modified: src/Makefile.defs --- Diff: https://github.com/kamailio/kamailio/commit/bca9768b6f2667bad8472fa99a113b8… Patch: https://github.com/kamailio/kamailio/commit/bca9768b6f2667bad8472fa99a113b8… --- diff --git a/src/Makefile.defs b/src/Makefile.defs index 3d28f3ef38..f6f39e3a01 100644 --- a/src/Makefile.defs +++ b/src/Makefile.defs @@ -210,9 +210,18 @@ endif endif +# dlopen requires -ldl on some systems, but not others.
