Free pascal datetime6/10/2023 ![]() SQLiteLibraryName : = '/usr/lib/libsqlite3.dylib' Īs mentioned before: SQLite uses a single file for an entire database. SQLiteDefaultLibrary : = 'libsqlite3.so' Also note that the path under Raspbian is different. Copying it will copy the actual binary, not the link. Note : libsqlite3.so.0 is actually just a symbolic link to a particular library version, for example libsqlite3.so.0.8.6. Note : I noticed that in some forums that people mention ‘/usr/lib64’ for 64-bit systems, but I cannot confirm this to be true or not. In the example below we have our project files saved in ~ /Desktop /MyProject and in this step we will also rename the file to libsqlite3.so .įinally, we’d like Lazarus to find the library during design time and for that we make a soft link in the /usr /lib / directory which we will call ‘libsqlite3.so’ as well (it’s what Lazarus will be looking for). The next step, and I’m sure there might be better ways to do this, is to copy the library in your project folder which I always like to do, just to make sure I’m testing with the right library file, and to help me make a distribution zip file later on. Tip : If you could not find the file there, use the “locate” statement to determine the location of “libsqlite3.so.0”. You’ll now find the SQLite library in the following location: /usr /lib /i386-linux-gnu /libsqlite3.so.0 (Note: for Raspberry Pi 2 model B /usr /lib /arm-linux-gnueabihf /libsqlite3.so.0): ![]() Sudo apt-get install sqlite3 libsqlite3-dev You also have to keep in mind that, unlike more advanced SQL servers, you manually have to commit changes. Single User implies that the database file can be opened by one application at a time only. I did a lot of testing with different database engines, but SQLite is clearly the winner when you’re looking for a tiny single user SQL based database engine available that is available on multiple platforms.įirst of all, SQLite stores all it’s data in a single file and is intended for single user only – as with most embedded SQL engines. SQLite can be found on numerous platforms, anything from Android, Apple MacOS X, Apple iOS, Microsoft Windows, Linux, etc. Both of these actually have an embedded version as well, but are much more complex to install and use, much more resource hungry and not as widely supported as one would hope. Typical use of SQLite is when you’d like to use an SQL database to store application data without the need to run a large SQL database like for example MySQL (my favorite) or FireBird. Airbus even uses it planes (for more famous users see Well-Known SQLite users). Well known companies like Apple, Adobe, Microsoft, Skype, Mozilla, and Google use SQLite for some of their products. SQLite is a small SQL database engine used in more applications than you’d think – you’re probably using SQLite already without even knowing it.

It is assumed (but not required) that the user has the most recent stable release of the FPC compiler. There are no requirements to view the HTML documentation other than a relatively modern web browser that supports CSS Level 3 and Javascript. As a convenience (and to avoid 404 errors), it mirrors the FPC documentation available on SourceForge. Lazarus documentation includes links to topics in Free Pascal documentation files. Version, revision, and date information are displayed at the bottom of each page. ![]() The files on this site are updated "periodically" as new help content dictates. LazDocsNext is comparable to the daily documentation generated for the FPC compiler at. Official documentation releases are provided when a new version of the IDE is available. It provides a way to preview changes to the documentation for the next Lazarus IDE release. LazDocsNext is a perpetual work-in-progress. Other packages may be included in this project when they become available. It contains the HTML output generated for the packages. This project contains the documentation for packages found in the development branch of the Lazarus IDE (). ![]()
