Build GingerBread on 32 bit machine.-CSDN博客

I tried and it works http://forum.xda-developers.com/showpost.php?p=9998281&postcount=12

A quick and brutal fix is to:
1) go to gingerbread/prebuilt/linux-x86/toolchain
2) rename arm-eabi-4.4.3 to arm-eabi-4.4.3.old
3) link arm-eabi-4.4.0 to arm-eabi-4.4.3

Code:

cd gingerbread/prebuilt/linux-x86/toolchain
mv arm-eabi-4.4.3 to arm-eabi-4.4.3.old
ln -s arm-eabi-4.4.0  arm-eabi-4.4.3

One more fix needed to build on x86 is to change

Code:

# This forces a 64-bit build for Java6
LOCAL_CFLAGS += -m64
LOCAL_LDFLAGS += -m64

in the Android.mk files of the gingerbread/external/clearsilver/ directory
and subdirectories to:

Code:

# This forces a 64-bit build for Java6
LOCAL_CFLAGS += -m32
LOCAL_LDFLAGS += -m32

This should be fixed in a more elegant way based on the host arch.

Started to compile now....................................Done.
Works so far.

Patch attached to fix build on 32 bit hosts.

另外还需要修改 rename
