Why do I get "Header file missing" (make error)?

Question

I'm trying to install a geocoder for a website I'm building. I'm using Geocoder because the query limit for the Google Maps API falls short of my needs. I installed all the gems required and have SQLite3. When I'm actually trying to install the geocoder gem (Geocoder::US) I get an error while running the make file.

I'm getting an error I cannot figure out. It mentions the error (in the title) then talks of an non-existent file (sqlite3ext.h). Here is the error:

I know this is vague but I've been working for 10+ hours trying to install this and have found little help online. Any advice on which direction to go would be appreciated.

Answer 1

This is from the project's Readme:

To build Geocoder::US, you will need gcc/g++, make, bash or equivalent, the standard *NIX ‘unzip’ utility, and the SQLite 3 executable and development files installed on your system.

It seems that you lack the SQLite3 development headers.

This is relevant:

NOTE: If you do not have /usr/include/sqlite3ext.h installed, then your sqlite3 binaries are probably not configured to support dynamic extension loading. If not, you must compile and install SQLite from source, or rebuild your system packages. This is not believed to be a problem on Debian/Ubuntu, but is known to be a problem with Red Hat/CentOS.

Also they do not mention Windows. You should:

1. Ask them if someone uses it on Windows and if there are instructions for that.
2. Evaluate the thing on Linux, Debian/Ubuntu especially.

Answer 2

-fPiC is not your problem. As the log states, the compiled code is already position independent. The problem is, that the sqllite3ext.h is not in the compiler include path.
