Deploy jpostal/libpostal into EC2 instances

Question

I am trying to deploy jpostal artifacts into an EC2 instances so that our web application can use the library. As I understand, jni files in "scr/main/jniLibs" are linking to c libraries in "/usr/local/include/libpostal" and "/usr/local/lib/". However, I do not have permission to write "libpostal.h" into "/usr/local/include/libpostal" and "pkgconfig,libpostal.a,libpostal.la,libpostal.so,libpostal.so.1,libpostal.so.1.0.0" into "/usr/local/lib/" in the EC2 instances. Is there any solution for this?

Thanks.

I managed to build and save all artefacts into a local folder, e.g. "/app/libpostal/" and then the deployment process is simply copying them to the same folder in a EC2 machine. The key thing is to use ./configure command to specify all the folders to store the artefacts and there is a tricky step where I use my own jpostal_build.sh instead of the default one:

1. Custom "jpostal_build.sh" has 2 lines:

./bootstrap.sh

./configure --libdir=/app/libpostal/jniLibs make install

2. The main script "generate_jpostal_artifacts.sh":

#!/bin/bash
