ok6410 android driver(6)

　　This is a short essay about the mistakes in compiling ok6410 android-2.3 source codes.

　　If there is nothing happen when you compiling forlinx android-2.3, just go past.

 

　　My local host is 64bit system, but the forlinx android souce code was compiler on 32bit.

　　So we should change the follwing files : (You could also check this in the UserGuide.pdf of forlinx on charpter 8)　　

/external/clearsilver/cgi/Android.mk
/external/clearsilver/cs/Android.mk
/external/clearsilver/util/Android.mk
/external/clearsilver/java-jni/Android.mk

 

　　Change -m32 to -m64 :

# 32 bit
#LOCAL_CFLAGS += -m32
#LOCAL_LDFLAGS += -m32
# 64 bit
LOCAL_CFLAGS += -m64
LOCAL_LDFLAGS += -m64

　　Then change the /build/core/main.mk

ifneq (64,$(findstring 64,$(build_arch)))
#for 32-bit
#ifneq (i686,$(findstring i686,$(build_arch)))

　　Finally, check your gcc and g++ version.

　　My localhost gcc and g++ are version 4.7, so I install gcc-4.6 and g++-4.6-multilib to relink the gcc and g++.

 

$ sudo rm -rf /usr/bin/gcc /usr/bin/g++
$ sudo ln -s /usr/bin/gcc-4.6 /usr/bin/gcc
$ sudo ln -s /usr/bin/g++-4.6 /usr/bin/g++

 

　　We still need to change the following two files : 

 

　　(1) build/core/combo/HOST_linux-x86.mk 

 

#HOST_GLOBAL_CFLAGS += -D_FORTIFY_SOURCE=0
HOST_GLOBAL_CFLAGS += -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0

 

　　(2) farmework/base/libs/utils/Android.mk

#LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS)
#LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS) -fpermissive
