toolchain problem

[bhoj]

Whenever I try to compile any library by writing an android makefile I
am getting such errors. I have no idea how to go about this.

/tmp/ccOVNK9d.s: Assembler messages:
/tmp/ccOVNK9d.s:249: Error: unshifted register required -- `eor

Is there any flags that I should set in Android makefile ?

[David Turner]

Hello,

It looks like the assembler is complaining that the content of the .s file is not Thumb.

can you tell us more about how you configure your build, what is in your Android.mk file and how you invoke the toolchain ?. I suspect some misconfiguration, somewhere.

[vishal bhoj]

Yes it was the problem with the configurations of the toolchain now I have added the CFLAGS  -mno-thumb-interwork -mno-thumb -marm
and I hence I am not getting those errors now . Is this the right way . this is the format of my Android makefile  NOW.


LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_SRC_FILES:= \


LOCAL_CFLAGS +=-O4  -mno-thumb-interwork -mno-thumb -marm
LOCAL_C_INCLUDES += \
$(LOCAL_PATH)/ \
$(LOCAL_PATH)/../

LOCAL_SHARED_LIBRARIES:=

LOCAL_STATIC_LIBRARIES:=

LOCAL_MODULE:=


include $(BUILD_SHARED_LIBRARY)


I first do source= build/envsetup.sh

and then build my library.

Is my procedure right ?

You can probably add the following line for your library to be
compiled in arm mode:

LOCAL_ARM_MODE := arm

-Ravi

[David Turner]

This is not the right procedure, the toolchain should deal with these details automatically.

Do you have inline assembly in your source code ? If this is true, you should do either one

of these things to force ARM compilation:

- define "LOCAL_ARM-MODE := arm" to force ARM compilation of all your sources

- otherwise, add your source file as "mysource.c.arm" instead of "mysource.c" to LOCAL_SRC_FILES, this will make only mysource.c built in ARM mode, the rest will be in thumb.

[vishal bhoj]

Thanks David , I will follow your instruction

I am able to compile but it fails at prelinking. I manually copy the shared object into obj/lib. How can I avoid this prelinking stage in the build process

You can add below line in your make file:

LOCAL_PRELINK_MODULE := false
