I’m installing GDAL on a Amazon Elastic Beanstalk EC2 and try to run a GeoDjango web application, but it returns an error about missing C library’s. Which is very odd. I’m installing the GDAL, Geos, Proj4 libraries from source via this guide and they are being stored in /usr/local/geos, /usr/local/gdal, /usr/local/proj4 on the EC2. The $LD_Library Path on the EC2 is:
The Errors mention the following missing Libraries: - Libcrypto.so.1.1 (solved by updating OpenSSL on EC2) - Libjson-c.so.3 (not solved, still missing see error)
Apache is returning the following error when it tries to run Django GeoDjango.
