statically linking c file with android bionic c library

Question

I just wrote a small c file and its header file. dev_access.c and dev_access.h

I want to link it to the bionic library in android and create a statically/dynamically linked archive file.

My files are in /home/preetam/mydev/ The android sources are in /home/preetam/android_source

The following is my current makefile

CROSS           := /home/preetam/bin/CodeSourcery/arm2010/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi
CC              := $(CROSS)-gcc
INC_DIR         := /home/preetam/android_source/bionic/libc
CFLAGS          := -Wall -c -I$(INC_DIR)/include

android_hal: dev_access.o
        ${CC} ${CFLAGS} dev_access.c -o dev_access.a

clean:
        rm -f *.o dev_access.a

I am not sure whats going wrong but header files are not linking and some missing and redefinition errors are coming up. The following is the Console output:

/home/preetam/bin/CodeSourcery/arm2010/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc -c -Wall -I/home/preetam/android_source/bionic/libc/include -static   -c -o dev_access.o dev_access.c
In file included from /home/preetam/android_source/bionic/libc/include/stdio.h:42,
                 from dev_access.c:1:
/home/preetam/android_source/bionic/libc/include/sys/_types.h:40: fatal error: machine/_types.h: No such file or directory
compilation terminated.
make: *** [dev_access.o] Error 1

First of all, Is my Makefile correct? Whats the proper way to link your programs with bionic libc ? How to make the final object an archive?

Answer 1

You should be using these include paths for bionic:

libc/arch-$ARCH/include 
libc/include 
libc/kernel/common 
libc/kernel/arch-$ARCH

ar might have some switches for it...

EDIT: The switch is cr

ar -crv <libname> <source_object>
