交叉编译libupnp

1.从Makeconfig中拿到CFLAGS,LDFLAGS等编译参数&＃xff0c;执行./configure 然后再make&＃xff0c;make install。
2.拷贝编译出来的动态库和静态库到lib_release下对应的文件夹中&＃xff0c;编译出来的库的路径在./configure –prefix&＃61;”路径”下。
3.在system/project/TV010XX/Makefile中添加编译选项&＃xff0c;并指定头文件和库文件的路径&＃xff0c;由于目标机并没有对应的动态链接库所以添加选项-static。如下&＃xff1a;

1. INCLUDES &＃43;&＃61; -I../../open_source/libupnp/libupnp-1.6.20/install/include/upnp
2. LIBS &＃43;&＃61; -L../../lib_release/prebuilt_$(TOOLCHAIN_VER)
3. #LIBS &＃43;&＃61; -L../../open_source/libupnp/libupnp-1.6.20/install/lib
4. LDFLAGS &＃43;&＃61; -Wl,-rpath,../../lib_release/prebuilt_$(TOOLCHAIN_VER)
5. LIBS &＃43;&＃61; -lthreadutil
6. LIBS &＃43;&＃61; -lixml
7. LIBS &＃43;&＃61; -lupnp
8. LDFLAGS &＃43;&＃61; -static

4.调用upnp,只需要在文件头添加#include "upnp.h"即可&＃xff0c;经测试可正常运行。

5.具体Makefile,和preconf.sh。

1. include ../../include/MakeConfig
3. LIBUPNPDIR&＃61;libupnp-1.6.20
4. CURRENT_FOLDER&＃61;$(shell pwd)
6. MYNM&＃61;$(TOOLCHAIN_ROOT)/$(HOST)-nm
7. MYCFLAGS &＃61; $(TOOLCHAIN_DIR)/include
8. MYLDFLAGS &＃61; $(TOOLCHAIN_DIR)/lib
9. all:
10. cd $(LIBUPNPDIR); $(SH) CC_TOOLCHAIN&＃61;$(_CC) CXX_TOOLCHAIN&＃61;$(_CXX) RANLIB_TOOLCHAIN&＃61;$(MYRANLIB) LD_TOOLCHAIN&＃61;$(MYLD) STRIP_TOOLCHAIN&＃61;$(MYSTRIP) AR_TOOLCHAIN&＃61;$(MYAR) NM_TOOLCHAIN&＃61;$(MYNM) CFLAGS_TOOLCHAIN&＃61;$(MYCFLAGS) LDFLAGS_TOOLCHAIN&＃61;$(MYLDFLAGS) MYPREFIX&＃61;$(CURRENT_FOLDER)/$(LIBUPNPDIR)/install ../preconf.sh $(HOST) ;$(MAKE);$(MAKE) install
11. cp -fd $(LIBUPNPDIR)/install/lib/lib* ../../lib_release/prebuilt_$(TOOLCHAIN_VER)
12. #cp $(LIBUPNPDIR)/upnp/inc/*.h $(LIBUPNPDIR)/ixml/inc/*.h $(LIBUPNPDIR)/threadutil/inc/*.h ../../project/TV010_EuroDVB
13. clean:
14. cd $(LIBUPNPDIR);$(MAKE) clean
