因?yàn)轫?xiàng)目需要在android的NDK開發(fā)中使用pcre正則表達(dá)式庫，而android系統(tǒng)中并沒有自帶該庫，所以就得另外移植了， 下面是移植的詳細(xì)步驟：

?

1. 下載pcre源碼，可以到http://sourceforge.net/projects/pcre/下載源碼。
我這里使用的是pcre-7.8.tar.gz 。

2. 將pcre-7.8 的源碼拷貝至android源碼樹下的external/pcre目錄下。

3. 將下面的Android.mk文件拷貝到external/pcre目錄下。

Android.mk:

# # Android makefile for libpcre # # This makefile generates libpcre.a, pcregrep and pcre.h ONLY. # It should be amended to build libpcreposix.a, libpcrecpp.a # and tests.LOCAL_PATH := $(call my-dir)### ### Build libpcre.a and pcre.h ###include $(CLEAR_VARS)#step 1: # to generate the files config.h pcre.h pcre_chartables.c # GEN := $(LOCAL_PATH)/config.h $(GEN): $(LOCAL_PATH)/config.h.generic$(hide) cp $(LOCAL_PATH)/config.h.generic $@ LOCAL_GENERATED_SOURCES += $(GEN)GEN := $(LOCAL_PATH)/pcre.h $(GEN): $(LOCAL_PATH)/pcre.h.generic$(hide) cp $(LOCAL_PATH)/pcre.h.generic $@ LOCAL_GENERATED_SOURCES += $(GEN)GEN := $(LOCAL_PATH)/pcre_chartables.c $(GEN): $(LOCAL_PATH)/pcre_chartables.c.dist$(hide) cp $(LOCAL_PATH)/pcre_chartables.c.dist $@ LOCAL_GENERATED_SOURCES += $(GEN)#step 2: #clear the vars generated by the step 1 # include $(CLEAR_VARS)LOCAL_SRC_FILES := \pcre_compile.c \pcre_config.c \pcre_dfa_exec.c \pcre_exec.c \pcre_fullinfo.c \pcre_get.c \pcre_globals.c \pcre_info.c \pcre_internal.h \pcre_maketables.c \pcre_newline.c \pcre_ord2utf8.c \pcre_refcount.c \pcre_study.c \pcre_tables.c \pcre_try_flipped.c \pcre_ucd.c \pcre_valid_utf8.c \pcre_version.c \pcre_xclass.c \pcre_chartables.c \ucp.h \pcre.h \config.h#copy the pcre.h to out/target/product/generic/obj/include/libpcre # LOCAL_COPY_HEADERS := pcre.h LOCAL_COPY_HEADERS_TO := libpcreLOCAL_CFLAGS += -O3 -I. -DHAVE_CONFIG_HLOCAL_MODULE := libpcre LOCAL_MODULE_CLASS := STATIC_LIBRARIES LOCAL_PRELINK_MODULE := falseinclude $(BUILD_STATIC_LIBRARY)### ### Build pcregrep ###include $(CLEAR_VARS)LOCAL_MODULE := pcregrep LOCAL_SRC_FILES := pcregrep.c LOCAL_CFLAGS += -O3 -I. -DHAVE_CONFIG_H LOCAL_STATIC_LIBRARIES := libpcreinclude $(BUILD_EXECUTABLE)

4. cd 到 android的源碼樹的根目錄下，輸入命令：

. build/envsetup.sh

chooseproduct
mmm external/pcre
從下面的log可以看到生成了libpcre.a庫：

make: Entering directory `/home/braincol/workspace/android/android_build/android_sdk_froyo'

target thumb C: pcregrep <= external/pcre/pcregrep.c

make: Leaving directory `/home/braincol/workspace/android/android_build/android_sdk_froyo'

?

然后只要把libpcre.a庫和頭文件pcre.h拷貝到你的android應(yīng)用工程中，然后就可以在ndk中使用這個(gè)pcre庫了。
