Connecting problems with UniDAC 6.1.3 MySQL provider using Lazarus 1.4.2

[neseir]

Hi

I have problems connecting the UniDAC 6.1.3 source edition with a MySQL 5.1 service. Using the component design time works perfect getting all tables and listing information in the dataaware components. The problem is that when I tries to execute the program it claims first that there are some problems in the threading and then ends up with a 10061 message.

Switching from direct mode to client mode solves this but I then get problems with text fields are recognized as floats and it all crashes.

I have disabled the keep designtime connection to reduce the connections initiated from the application but with no difference. Using the same application code on windows works perfect with no problem connection to the database.

Have tested this using UniDAC 6.0.2 and 6.1.3 in Lazarus 1.2.6, 1.4.0 and 1.4.2. All end up with the same problem. Currently I'm using Ubuntu 14.04 LTS 64 bit edition (using the standard SqlDB components in Lazarus works perfect accessing the same database). I'm out of ideas to test and I'm quite confident that there is nothing to change on the remote MySQL instance since both designtime and standard MySQL components in all Lazarus versions works ok.

To resolve the problem, in the project file ( with the *.lpr extension) add the following string: {$DEFINE UseCThreads}, before {$IFDEF UNIX}{$IFDEF UseCThreads}
