What are sqlite development headers and how to install them?
header, pysqlite, python
Solution
debian/ubuntu:
$ apt-get install libsqlite3-dev # or rpm -i sqlite-devel-something.rpm
I think a number of interpreters just recompile their small connection libraries on installation, but to do that they need the C .h files in addition to the library to link against. You may already have the library, because something else depended on it, but you don't necessarily have the `dev` package, which is kind of half-way between source and binary.
Part of it is straightforward, if you are going to develop with a library you need its interface headers.
But I think something more happened, at first, people tried all-source and all-binary distributions, but the all-binary ones were vulnerable to dependency hell, and the all-source ones were overkill. I think now that an interesting compromise is in use, a semi-source distribution where a program links to installed libraries by recompiling those parts of it that link to extension libraries. This makes a lot of sense with interpreters where most of the system can arrive in binary but the extension modules are dynamically loaded and compiled for the installed system. I think.
Problem
I am trying to install pysqlite and have troubles with that. I found out that the most probable reason of that is missing sqlite headers and I have to install them. However, I have no ideas what these headers are (where I can find them, what they are doing and how to install them). Can anybody, pleas, help me with that?
