# 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的源码树的根目录下输入命令 . build/envsetup.sh chooseproduct mmm external/pcre 从下面的log可以看到生成了libpcre.a库 make: Entering directory /home/braincol/workspace/android/android_build/android_sdk_froyo Header: out/target/product/generic/obj/include/libpcre/pcre.h target thumb C: pcregrep external/pcre/pcregrep.c target thumb C: libpcre external/pcre/pcre_compile.c target thumb C: libpcre external/pcre/pcre_config.c target thumb C: libpcre external/pcre/pcre_dfa_exec.c target thumb C: libpcre external/pcre/pcre_exec.c target thumb C: libpcre external/pcre/pcre_fullinfo.c target thumb C: libpcre external/pcre/pcre_get.c target thumb C: libpcre external/pcre/pcre_globals.c target thumb C: libpcre external/pcre/pcre_info.c target thumb C: libpcre external/pcre/pcre_maketables.c target thumb C: libpcre external/pcre/pcre_newline.c target thumb C: libpcre external/pcre/pcre_ord2utf8.c target thumb C: libpcre external/pcre/pcre_refcount.c target thumb C: libpcre external/pcre/pcre_study.c target thumb C: libpcre external/pcre/pcre_tables.c target thumb C: libpcre external/pcre/pcre_try_flipped.c target thumb C: libpcre external/pcre/pcre_ucd.c target thumb C: libpcre external/pcre/pcre_valid_utf8.c target thumb C: libpcre external/pcre/pcre_version.c target thumb C: libpcre external/pcre/pcre_xclass.c target thumb C: libpcre external/pcre/pcre_chartables.c target StaticLib: libpcre (out/target/product/generic/obj/STATIC_LIBRARIES/libpcre_intermediates/libpcre.a) target Executable: pcregrep (out/target/product/generic/obj/EXECUTABLES/pcregrep_intermediates/LINKED/pcregrep) target Non-prelinked: pcregrep (out/target/product/generic/symbols/system/bin/pcregrep) target Strip: pcregrep (out/target/product/generic/obj/EXECUTABLES/pcregrep_intermediates/pcregrep) Install: out/target/product/generic/system/bin/pcregrep make: Leaving directory /home/braincol/workspace/android/android_build/android_sdk_froyo 然后只要把libpcre.a库和头文件pcre.h拷贝到你的android应用工程中然后就可以在ndk中使用这个pcre库了。转载于:https://www.cnblogs.com/hibraincol/archive/2011/10/15/2213714.html
