From fb58545f8d1c5fa32122244caeaf3625c12ddc01 Mon Sep 17 00:00:00 2001 From: Shiz Date: Sun, 28 Jun 2015 23:08:21 +0200 Subject: add musl-clang, a wrapper for system clang installs musl-clang allows the user to compile musl-powered programs using their already existent clang install, without the need of a special cross compiler. it achieves this by wrapping around both the system clang install and the linker and passing them special flags to re-target musl at runtime. it does only affect invocations done through the special musl-clang wrapper script, so that the user setup remains fully intact otherwise. the clang wrapper consists of the compiler frontend wrapper script, musl-clang, and the linker wrapper script, ld.musl-clang. musl-clang makes sure clang invokes ld.musl-clang to link objects; neither script needs to be in PATH for the wrapper to work. --- Makefile | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'Makefile') diff --git a/Makefile b/Makefile index a1c19284..5f740057 100644 --- a/Makefile +++ b/Makefile @@ -52,6 +52,7 @@ ALL_LIBS = $(CRT_LIBS) $(STATIC_LIBS) $(SHARED_LIBS) $(EMPTY_LIBS) $(TOOL_LIBS) ALL_TOOLS = tools/musl-gcc WRAPCC_GCC = gcc +WRAPCC_CLANG = clang LDSO_PATHNAME = $(syslibdir)/ld-musl-$(ARCH)$(SUBARCH).so.1 @@ -160,6 +161,10 @@ tools/musl-gcc: config.mak printf '#!/bin/sh\nexec "$${REALGCC:-$(WRAPCC_GCC)}" "$$@" -specs "%s/musl-gcc.specs"\n' "$(libdir)" > $@ chmod +x $@ +tools/%-clang: tools/%-clang.in config.mak + sed -e 's!@CC@!$(WRAPCC_CLANG)!g' -e 's!@PREFIX@!$(prefix)!g' -e 's!@INCDIR@!$(includedir)!g' -e 's!@LIBDIR@!$(libdir)!g' -e 's!@LDSO@!$(LDSO_PATHNAME)!g' $< > $@ + chmod +x $@ + $(DESTDIR)$(bindir)/%: tools/% $(INSTALL) -D $< $@ -- cgit 1.4.1
