[SOLVED] Lazarus refuses to load libmysql.dll

[balazsszekely]

All fixed - had to install all of the VC++ redistributables and the VC Runtime libraries.  After those were installed it started working! Thanks GetMem for your help - that drove me to look for the runtimes - downloaded dependency walker and found out why they weren't loading.

Ok. I'm glad it's working.

Perhaps the libmysql.dll depends on one of the runtimes... the specific file that dependency walker was choking on was msvcr120.dll

it looks if the dll have depencies, not fullfilled on a fresh system.

Yes and I am sure the runtimes were installed on the other system because I also have Visual Studio Community installed so the runtimes probably got installed with that.  The msvcr120.dll appears to be part of the Visual C runtime for Visual Studio 2013.

You could try libmysql.dll from HeidiSQL installation, it probably doesn't have dependency.

I did try this but it's version 5.6 so I didn't get the error about the specified module but got expected version 5.7 and got version 5.6 so it looks like it maybe is statically linked with all the dependencies - and it did appear to work with the 5.6 connection object.
