# Erlang wrapper for SQLite3
|
|
|
|
This library allows you to work with SQLite3 databases from Erlang.
|
|
|
|
It is compatible with Windows and Linux, and should probably work on other OSes as well.
|
|
|
|
[](https://travis-ci.org/alexeyr/erlang-sqlite3)
|
|
|
|
## Requirements
|
|
|
|
Erlang/OTP R16B or 17.x is required, and SQLite 3 minimum version is 3.6.1. See R14B branch for older Erlang versions.
|
|
|
|
## Compiling
|
|
|
|
### Linux
|
|
|
|
1. Install SQLite3 by running `sudo apt-get install sqlite3` or the equivalent for your package manager, or by [compiling from the source](http://source.online.free.fr/Linux_HowToCompileSQLite.html).
|
|
|
|
2. `make`.
|
|
|
|
### Cross-compiling
|
|
|
|
If you want to use erlang-sqlite3 on an embedded device, it can be cross-compiled.
|
|
|
|
1. Cross-compile [SQLite3](http://www.sqlite.org/cvstrac/wiki?p=HowToCompile) and [Erlang](http://www.erlang.org/doc/installation_guide/INSTALL-CROSS.html).
|
|
|
|
2. Change variables and paths in `rebar.cross_compile.config.sample` to the desired values and rename it to `rebar.cross_compile.config`.
|
|
|
|
3. `make cross_compile`.
|
|
|
|
### Windows with MS Visual C++
|
|
|
|
1. Download both the source amalgamation and the precompiled binary from http://www.sqlite.org/download.html. Extract files `sqlite3.h` from the amalgamation and `sqlite3.def` from the binary. Run this command from Visual Studio command prompt:
|
|
|
|
lib /def:sqlite3.def
|
|
|
|
to create the import library `sqlite3.lib`. In `rebar.config`, set the correct paths in tuples `{"win32", "CFLAGS", "/Idirectory/containing/sqlite3.h/ /Ic_src /W4 /wd4100 /wd4204"}` and `{"win32", "LDFLAGS", "/path/to/sqlite3.lib"}`.
|
|
|
|
2. `nmake`.
|
|
|
|
### Potential compilation problems
|
|
|
|
* On Windows, `sqlite3.dll` usually won't be installed in the system-wide DLL search path. In this case, it should be placed in the working directory of your application.
|
|
|
|
* If SQLite was built with `SQLITE_OMIT_LOAD_EXTENSION` option, you'll need to undefine `ERLANG_SQLITE3_LOAD_EXTENSION` macro in <c_src/sqlite3_drv.h>.
|
|
|
|
## Running the test suite
|
|
|
|
### Linux
|
|
|
|
`make test`
|
|
|
|
### Windows
|
|
|
|
1. `nmake tests`
|
|
|
|
2. If you get the error `"Error loading sqlite3_drv: The specified module could not be found"`, this is because `sqlite3.dll` isn't in the search path. Copy it to the `.eunit` directory.
|
|
|
|
## Example usage
|
|
|
|
See tests `test/sqlite3_test.erl` for a starting point.
