[strongSwan-dev] Strongswan on ICS vstr library build failure

[Mrunal Upadhyay]

Dear Experts,

Based on the steps mentioned at the below link, I started with Vstr library building on the ICS workspace.

http://wiki.strongswan.org/projects/strongswan/wiki/Android

1. Downloaded and extracted droid-gcc tmurakam-droid-wrapper-v1.0.4-5-g04eb4dc package
2. Ran make install. ( It installed the necessary droid-gcc and droid-ld in /usr/local/bin directory)
3. Downloaded and extracted the vstr-1.0.15.tar.bz2 package from download.strongswan.org site.
4. Changed the DROID_ROOT and optionally DROID_TARGET and INSTALLDIR path locations appropriately in vstr.build
5. Ran the below steps:
	cd vstr-1.0.15
	patch -p1 < ../vstr.patch
	. ../vstr.build
6. I could see the libvstr.a, include files and Android.mk files getting created in the android/external/strongswan-support directory.
7. However, I am not able to make the libvstr module. I get the following error  when I try to make libvstr module as a shared library:

collect2: ld returned 1 exit status
make: *** [out/target/product/ics/obj/SHARED_LIBRARIES/libvstr_intermediates/LINKED/libvstr.so] Error 1

It would be great if anyone has come across this error and can help in tackling this build error problem where as mentioned in the Makefile, we are trying to create a Shared Library from the Static Library libvstr.a

Once the above build error is resolved, I will check on building the strongswan source in android/external/strongswan-4.6.2 directory.

Thank You very much,
