### Building with older iOS SDK versions
The script should work out of the box for the iOS 8.x SDKs and probably newer releases as well.
If you are using SDK version 7.x or older, you need to specify the exact SDK version inside **build.sh**, for example:
```
IOS_SDK_VERSION=7.1
```
### Optimization
By default, no compiler optimizations are specified inside the build script. For an optimized build, add the corresponding flags to the CFLAGS definition inside **build.sh**.

------------
I) native library
I) native library, for example by issuing this command in jassimp-native/src:
$ gcc jassimp.cpp -I/usr/lib/jvm/default/include/ \
-I/usr/lib/jvm/default/include/linux -lassimp -shared -fPIC -o libjassimp.so
libjassimp.so is required at runtime and must be located in java.library.path.
II) Java binding
The java library is built using ant. Executing "ant" in the port/jassimp
