From d8a892bd560513b50f625f42b8e886ea84c1ccd2 Mon Sep 17 00:00:00 2001 From: midipix Date: Nov 25 2018 14:18:58 +0000 Subject: build system: PE, ELF: defined DSO_REF_VER, DSO_REF_SONAME, DSO_REF_SOLINK. These definitions come in handy when a project generates alongside its ``primary shared library'' one or more ``extension libraries'' that depend on it. When the rules for generating extension libraries use the $^ directive, the above dependency must be declared in a target-aware manner. In most cases, one would want to express this dependency by way of $(DSO_REF_SONAME), thereby pulling in lib/libfoo.so.$(MAJOR) on ELF targets, lib/libfoo.$(MAJOR).lib.a on midipix targets, and lib/libfoo.$(MAJOR).dll.a on win32 targets. --- diff --git a/sysinfo/os/elf.mk b/sysinfo/os/elf.mk index 5a3940f..6878c6a 100644 --- a/sysinfo/os/elf.mk +++ b/sysinfo/os/elf.mk @@ -1,2 +1,6 @@ +DSO_REF_VER = $(SHARED_LIB) +DSO_REF_SONAME = $(SHARED_SONAME) +DSO_REF_SOLINK = $(SHARED_SOLINK) + LDFLAGS_SHARED += -Wl,-soname LDFLAGS_SHARED += -Wl,$(DSO_SONAME) diff --git a/sysinfo/os/pe.mk b/sysinfo/os/pe.mk index e8e1759..c3c5ba0 100644 --- a/sysinfo/os/pe.mk +++ b/sysinfo/os/pe.mk @@ -1,3 +1,7 @@ +DSO_REF_VER = $(IMPLIB_VER) +DSO_REF_SONAME = $(IMPLIB_SONAME) +DSO_REF_SOLINK = $(IMPLIB_SOLINK) + LDFLAGS_IMPLIB += -Wl,--output-def LDFLAGS_IMPLIB += -Wl,$(IMPLIB_DEF) LDFLAGS_SHARED += $(LDFLAGS_IMPLIB)
