I don't normally use the Lazarus MS SQL components, but tried using them today on Ubuntu Linux and keep experiencing lots of random access violations. I wanted to know if this is a normal thing, or if perhaps the state of these components is fragile on Linux. Here is what is happening. I can place the TSQLConnection, TSQLTransaction, TSQLQuery, TDataSource and data aware controls on a form and connect to the database at design time. It works fine. I can run my program and I can view and edit records just fine. But if I change any part of TSQLQuery down to TSQLConnection setting Active to False, then I get access violations. This is particularly problematic because certain changes to component properties require Active to be set to False, such as editing SQL. And very often, though not always, changing the Active property results in access violations. And after an AV happens then things start misbehaving in the IDE. Is this a common problem for some people on Linux using the MS SQL components? Am I doing something wrong? Are there people her who have worked with MS SQL components on Linux much and is familiar with this problem?
This is not normal. I have not used the MS SQL Connector on linux, but I have used it on windows, and I have not experienced such things. Can you post a stack trace so we can analyze the problem ?
