Access to MySQL databases with Lazarus.<\/p>\n

<\/p>\n

Today I played around a bit with Lazarus and wanted to access a MySQL database. A bit like before, just drag the components onto the form, configure and done? Unfortunately not quite. At runtime there was an error message:<\/p>\n

\"\"<\/p>\n

\r\nCan not load default MySQL library (\"libmsysql.dll\" or \"libmysql.dll\"). Check your installation.\r\n<\/pre>\n
So here you still need a special DLL to access the database. But where do you get the DLL? The download is available here<\/a>.<\/p>\n
The file can be found in the ZIP archive.<\/p>\n
\"\"<\/p>\n
It is important to download the appropriate version. Then add the DLL to the programme directory. In my case, the 5.7 version was the right one for now. Unfortunately, I still had problems with the new 8 version. I’ll have to test it when I get the chance.<\/p>\n
\"\"<\/p>\n
Linux<\/h2>\n
As one would expect, there were also problems in Linux. The error message is similar here.<\/p>\n
\"\"<\/p>\n
\r\nCan not load default MySQL library (\"libmysqlclient.so.20\" or \"libmysqlclient.so\").\r\n<\/pre>\n
So the same problem. So just copy the appropriate files? Unfortunately, that didn’t really work. First of all, we download the appropriate Linux version.<\/p>\n
Unlike Windows, Linux does not search for the library in the programme directory. This only brings us the same error message again.<\/p>\n
\"\"<\/p>\n
Instead, we copy the files (symlinks and library) into the \/usr\/lib directory. Afterwards, the application started without any problems.<\/p>\n
