csdr Makefile for openwrt（纯粹笔记，暂未成功）

1、自已学着写的Makefile给csdr在openwrt平台上使用

参照：https://blog.csdn.net/lvshaorong/article/details/54668220

include $(TOPDIR)/rules.mk

PKG_NAME:=csdr
PKG_VERSION:=0.1
PKG_RELEASE:=1
PKG_SOURCE_PROTO:=git
PKG_SOURCE_URL:=https://github.com/simonyiszk/csdr.git
PKG_SOURCE_SUBDIR:=$(PKG_NAME)-$(PKG_VERSION)
PKG_SOURCE_VERSION:=6ef2a74206887155290a54c7117636f66742f858
PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION)-$(PKG_SOURCE_VERSION).tar.gz
PKG_MAINTAINER:=Andras Retzler, HA7ILM <randras@sdr.hu>
PKG_BUILD_DIR:=$(BUILD_DIR)/$(PKG_NAME)/$(BUILD_VARIANT)/$(PKG_NAME)-$(PKG_VERSION)

include $(INCLUDE_DIR)/package.mk

define Package/csdr
	SECTION:=net
	CATEGORY:=Network
	TITLE:=csdr is a command line tool to carry out DSP tasks for Software Defined Radio.
	URL:=https://github.com/simonyiszk/csdr
	DEPENDS:=+libfftw3

define Package/csdr/description
It can be used to build simple signal processing flow graphs, right from the command line. 
The included libcsdr library contains the DSP functions that csdr makes use of. 
It was designed to use auto-vectorization available in gcc, 
 and also has some functions optimized with inline assembly for ARM NEON 
 to achieve some speedup by taking advantage of SIMD command sets available in today's CPUs.
endef

define Package/csdr/conffiles
	/etc/config/csdr
endef

define Package/redsocks2/install
	$(INSTALL_DIR) $(1)/usr/bin $(INSTALL_BIN)
	$(PKG_BUILD_DIR)/csdr $(1)/usr/bin
	$(INSTALL_DIR) $(1)/etc/csdr
	$(INSTALL_DATA) ./files/csdr.template $(1)/etc/csdr/config.template
endef

$(eval $(call BuildPackage,csdr))

2、遇到个坑：

make编译时报了个错：has both : and :: entries

参考这里：http://www.voidcn.com/article/p-opfdcfpi-cc.html

解决：把每行的结尾空格都好好检查一次，去掉空格....
