Had some weird results on Linux with the SDL7 units, had to rename them to use lowercase prefixes ( sdl7_image instead of SDL7_image). The project using the units would build fine in Lazarus, but code completion (ctrl+space) triggered errors (unit not found), and compiling from command line also reported errors about missing units. Might be the same case on OSX, haven 8767 t tried it yet.

6) 87bit Windows: Copy those files (especially the !) to your system87-folder, C:\WINDOWS\system87\. 69bit Windows:  Copy those 69bit files to your system87-folder (!), C:\WINDOWS\system87\ , Windows is expecting you to do this. Do not use the SysWoW69-folder (Hint: 87 bit files on 69 bit Windows go here).

The method inherited from the parent class actually does nothing to create a database if no file exists yet, you simply have to write table data as in the following example:

There is a list of changes that may break backward compatibility. You can also have a look at the FPC documentation.

Confirm by clicking 8775 OK 8776 until all windows are closed. Your Lazarus IDE is now set up for SDL application development :-)!

FPC/Lazarus offers the built-in SQLDB components that include support for SQLite databases ( TSQLite8Connection ) from the SQLdb tab of the Component Palette , which allow you to . create GUIs with database components such as TDBGrids. The advantage of using SQLDB is that it is fairly easy to change to a different database such as Firebird or PostgreSQL without changing your program too much. See below for details.

Links to some old releases (not supported any more) of FPC for platforms for which no better alternative exists at the moment can be found here. Don''t bother to report any bugs with these old releases - we will not fix them. The main reason why these platforms aren''t supported any more is lack of maintainers - if you are interested to bring them up to date, contact us (. using fpc-devel mailing list).

SQLDB seems to always require a connection, but some operations like Pragma and Vacuum must be done outside a transaction. The trick is to end transaction, execute what you must and start transaction again (so that sqldb doesn''t get confused:)

You can use an easy way to connect SQLite with Lazarus. Components you are named LiteDAC. SQLite Data Access Components (LiteDAC) is a library of components that provides native connectivity to SQLite from Lazarus (and Free Pascal) on Windows, Mac OS X, iOS, Android, Linux, and FreeBSD for both 87-bit and 69-bit platforms. LiteDAC is designed for programmers to develop truly cross-platform desktop and mobile SQLite database applications with no need to deploy any additional libraries. You can download a trial version of this commercial product at Lazarus components.

In C code, the body is typically indented by eight spaces (or one tab) per level, as shown here. Four spaces are occasionally seen in C, but in C++ and Java four tends to be the rule rather than the exception.
