Question

I am trying to generate the executable something like adbd in /sbin.

The executable I wish to have is iwlist with ARM format and the type is static.

I added the folder in the AndroidSourceCode/external and execute the “mm” command to compile

LOCAL_PATH := $(call my-dir)
ifneq ($(TARGET_SIMULATOR),true)
include $(CLEAR_VARS)

LOCAL_MODULE := libiw

LOCAL_MODULE_TAGS := eng

LOCAL_SRC_FILES := iwlib.c

LOCAL_C_INCLUDE += LOCAL_PATH

LOCAL_PRELINK_MODULE := false

include $(BUILD_SHARED_LIBRARY)

#================================================
include $(CLEAR_VARS)
LOCAL_FORCE_STATIC_EXECUTABLE := true
LOCAL_MODULE_TAGS := eng
LOCAL_SRC_FILES := iwlist.c

LOCAL_SHARED_LIBRARIES := libiw
LOCAL_MODULE := iwlist

include $(BUILD_EXECUTABLE)
#================================================

endif # !TARGET_SIMULATOR

The above make file actually works by generating the iwlist executable with

 iwlist: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses
 shared libs), stripped

However, I am looking for the “statically linked” and I was thinking “LOCAL_FORCE_STATIC_EXECUTABLE := true” this line should help me make this executable statically.

Unfortunately, it doesnt.

Kindly instruct me if you know how to do it.

Thanks in advance.

I have a similar problem but I was not able to compile statically linked any file using the Android toolchain.
You can use another toolchain for that. I have tryied with the toolchain from linaro and It works fine.
You can download here:
https://wiki.linaro.org/WorkingGroups/ToolChain

I downloaded the 4.7 version, untar the file place in my home directory.
To compile is as easy as:

~/gcc-linaro-arm-linux-gnueabihf-2012.06-20120625_linux/bin/arm-linux-gnueabihf-gcc  -static -s hello.c -o hello

Of course I recommend you to put that bin directory in your path.

That will create a statically linked file:

# file hello
hello: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, for GNU/Linux 2.6.31, stripped
