Question

I have one shared library ,Which written in c build using arm-linux-androideabi-gcc compiler now i want to test my shared library so i written one sample c which call that shared library(.so) and i want to make .exe , so when i compile i got the error like this
this is my make file

      TARG_OS       = WIN32
BUILDTYPE     = Debug
OS_BITS = 32    

SRC     := TestLSBioCore.c 



OBJS = $(SRC:.c=.o)

OUT         = ./Test.exe

OUTLIB      = 

INCLUDE     = -I../../../../../../../android-ndk-r8b/platforms/android-8/arch-arm/usr/include -I../../include

LIBS        = libLSBioCore.so

CCFLAGS     = -O2 -w -D_POSIX_SOURCE

DEFS        =  "-D __MSYS__" "-D__NBISLE__"

i got the following error

i hope i gave the proper link in my make ,i can;t get what the error behind this,do anyone have idea about how to make exe using arm-linux-androideabi-gcc.

Answer 1

You have chosen a complicated way; note that with ndk-build you can build an executable much easier. For example, look at the test-libstdc++ NDK sample.

But using the bare make is also possible. You need more libraries though, when you set -nostdlib on your command line.

Add -lgcc. You may need more libs from toolchains/arm-linux-androideabi-4.6/prebuilt/windows/lib/gcc/arm-linux-androideabi/4.6.x-google to satisfy more references.
