在编译外置包时可能需要使用autoconf-archive，以下是添加autoconf-archive步骤。

修改tools/Makefile

修改tools/Makfile添加autoconf-archive编译路径

1. tools-$(BUILD_TOOLCHAIN) += gmp mpfr mpc libelf expat
2. – tools-y += m4 libtool autoconf automake flex bison pkg-config mklibs zlib
3. + tools-y += m4 libtool autoconf autoconf-archive automake flex bison pkg-config mklibs zlib
4. tools-y += sstrip make-ext4fs e2fsprogs mtd-utils mkimage
5. tools-y += firmware-utils patch-image quilt padjffs2
6. tools-y += mm-macros missing-macros cmake scons bc findutils gengetopt patchelf
7. tools-y += mtools dosfstools libressl
8. tools-$(CONFIG_TARGET_orion_generic) += wrt350nv2-builder upslug2
9. tools-$(CONFIG_TARGET_x86) += qemu
10. tools-$(CONFIG_TARGET_mxs) += elftosb sdimage
11. tools-$(CONFIG_TARGET_ar71xx) += lzma-old squashfs
12. tools-$(CONFIG_USES_MINOR) += kernel2minor
13. tools-y += lzma squashfs4
14. tools-$(BUILD_B43_TOOLS) += b43-tools
15. tools-$(BUILD_ISL) += isl
16. tools-$(CONFIG_USE_SPARSE) += sparse
17. tools-$(CONFIG_TARGET_apm821xx) += genext2fs

26. $(curdir)/autoconf/compile := $(curdir)/m4/compile

28. $(curdir)/automake/compile := $(curdir)/m4/compile $(curdir)/autoconf/compile $(curdir)/pkg-config/compile $(curdir)/xz/compile

添加autoconf-archive软件包

进入tools目录创建autoconf-archive文件夹，进入autoconf-archive创建Makefile

1. cd tools
2. mkdir autoconf-archive
3. cd autoconf-archive
4. touch Makefile

Makefile内容如下

1. #
2. # Copyright (C) 2006-2015 OpenWrt.org
3. #
4. # This is free software, licensed under the GNU General Public License v2.
5. # See /LICENSE for more information.
6. #
7. include $(TOPDIR)/rules.mk
9. PKG_NAME:=autoconf-archive
10. PKG_VERSION:=2013.11.01
12. PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.xz
13. PKG_SOURCE_URL:=@GNU/autoconf-archive
14. PKG_MD5SUM:=f01381c7d3570cf3fcf65093989e0d29
16. include $(INCLUDE_DIR)/host-build.mk
18. HOST_CONFIGURE_ARGS += \
19. –datarootdir=$(STAGING_DIR_HOST)/share
21. define Host/Compile
22. export SHELL=“$(BASH)”; $(MAKE) -C $(HOST_BUILD_DIR)
23. endef
25. define Host/Install
26. export SHELL=“$(BASH)”; $(MAKE) -C $(HOST_BUILD_DIR) install
27. endef
29. define Host/Clean
30. -export SHELL=“$(BASH)”; $(MAKE) -C $(HOST_BUILD_DIR) uninstall
31. $(call Host/Clean/Default)
32. endef
34. $(eval $(call HostBuild))

编译

make tools/autoconf-archive/{clean,compile} V=s
