Problem with LOCAL_LDLIBS -l on Windows/Cygwin

[tomgibara]

Great to see the NDK available.

I've got a small C++ library (which I've been developing thus far
using the platform build) that I'm trying to build under the NDK on
Windows XP. I've read through through the docs (which are great btw)
but have encountered a problem linking to liblog.so. My C is very
rusty, so apologies in advance if this is a dumb mistake on my part.

Here's my Android.mk

>>>>>
LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := mosey
LOCAL_SRC_FILES := mosey.cpp
LOCAL_LDLIBS := -llog

include $(BUILD_SHARED_LIBRARY)
>>>>>


The source compiles fine, but the linker complains:

/cygdrive/c/development/android/ndk-1.5_r1/build/prebuilt/windows/arm-
eabi-4.2.1/bin/../lib/gcc/arm-eabi/4.2.1/../../../../arm-eabi/bin/ld:
cannot find -llog
collect2: ld returned 1 exit status
make: *** [out/apps/mosey/android-1.5-arm/libmosey.so] Error 1


I was able to fix the problem by changing my Android.mk file to
include this:

LOCAL_LDLIBS := -Lbuild/platforms/android-1.5/arch-arm/usr/lib -
llog


I don't understand why this should be necessary when I can see using
the V=1 flag that -rpath-link includes build/platforms/android-1.5/
arch-arm/usr/lib

I faced the same problem here and I am also developing android
programs on cygwin.
Thanks for your solution, I'll try to check whether this resolves my
problem or not.

Faced same problem on MAC OS/X and the -L pointing to pre-built libs
fixed it too

LOCAL_MODULE := libnav
LOCAL_LDLIBS := -L${SYSROOT}/usr/lib -llog -lz

I had this same problem on XP/Cygwin. Setting the path fixed it for
me too.

Thanks
