[strongSwan] Strongswan on android

[antoine.david at fr.thalesgroup.com]

Hi,
 
As part of my internship I am trying to build strongswan on Android 2.2.
I have followed these steps using the special HOWTO for android provided on the strongswan website:
 
-I have downloaded the android 2.2.1 sources using repo
 
-I have built the sources (without strongswan) using the arm-eabi-gcc cross-compiler provided by the toolchain:
        cd /home/antoine/android-2.2.1
        . build/envsetup.sh
        lunch 1
        make
 
-Then I used droid-gcc to build the vstr library adjusting DROID_ROOT to my concerned directory (/home/antoine/android-2.2.1)
PS:The custom kernel is not yet built because I have planned to it after compiling the entire android sources including strongswan. It should normally won't be disturbing?
 
-I have donwloaded the last strongswan tarball (strongswan-4.5.1.tar.bz2) on the website and extracted it in my DROID_ROOT/external 
 
-Then when I try to re-build the android source tree 
        cd /home/antoine/android-2.2.1
        make
 
I get this error:

external/strongswan-4.5.1/src/libstrongswan/settings.c:23:18: error: glob.h: No such file or directory

The compiler doesn't find the glob.h file. Indeed this file is part of the glibc library of my linux host system but is not present in the libc for android, provided in DROID_ROOT/bionic. Android seems to have a partial support of the glibc. 
 
How could I fix this error?
Is there something I did wrong?
 
Regards,
 
Antoine
