Compiling pjsip on windows "C compiler cannot create executables"

I'm having trouble compiling pjsip on windows trough cygwin. I tried to use android branc of pjsip form http://svn.pjsip.org/repos/pjproject/branches/projects/android/ and Android NDK r8c for windows.

This is output when i try to configure pjsip.

$ ./configure-android
configure-android: APP_PLATFORM not specified, using android-14
configure-android: TARGET_ABI not specified, using armeabi
configure-android: calling ./configure with env vars:

CFLAGS =  -I/ndk/platforms/android-14/arch-arm/usr/include
CXXFLAGS =  -shared --sysroot=/ndk/platforms/android-14/arch-arm

Can anyone please tell how can I fix this....

If you look at config.log you'll see something like this:

aconfigure:2841: /cygdrive/c/android-ndk-r9/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/arm-linux-androideabi-gcc -I/cygdrive/c/android-ndk-r9/platforms/android-18/arch-arm/usr/include -I/cygdrive/c/android-ndk-r9/platforms/android-18/arch-arm/usr/include -nostdlib -L/cygdrive/c/android-ndk-r9/platforms/android-18/arch-arm/usr/lib/ conftest.c -lc -lgcc >&5

C:/android-ndk-r9/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/../lib/gcc/arm-linux-androideabi/4.4.3/../../../../arm-linux-androideabi/bin/ld.exe: cannot find -lc

The NDK's ld.exe is looking for libc (which is in arch-arm/usr/lib/) but it doesn't like cygwin paths. Change in configure-android the line

export LDFLAGS="${LDFLAGS} -nostdlib -L${ANDROID_SYSROOT}/usr/lib/"

to something like this:

export LDFLAGS="${LDFLAGS} -nostdlib -Lc:/android-ndk-r9/platforms/android-18/arch-arm/usr/lib/"

I managed to get past that error,but still didn't manage to compile pjsip. I switched to linux, where all works as it should....

Make sure you launch Cygwin As an Administrator on Windows, it made me struggle quite a bit when not doing so ^^
