Hello, I have a QT application that works with mysql. it runs perfectly in my system bu t now I runs in a new machine with the last gentoo 2006.1, so I do a new installation and when I run this application, it stops the mysql daemon. Now I decide to work with another mysql server in other machine and the mysql don't stop. So now I'm sorprised about what happens. I suspect about gcc version so I downgraded from gcc-4.4.1 to gcc-3.4.5. And now I re-emerge the mysql. Now the application goes ok and mysql daemon don't stops. I gives you emerge --info but is with gcc-3.4.5 because I don't have more time to put gcc-4.4.1. Now my clients can work. Another thing that I want to comment is that I don't works with QT from portage I install qt from trolltech, but this is not a problem. When I had this problem I tried to do a very little qt program, only a main.cpp with a very little Insert sql, and I do an Insert of value 100 for example, and then I go to a mysql console and I do a select and the sourprise is that no inserts value 100 it inserts value 198...

I don't understand what you mean by "stop mysql daemon". Does it segfault or what? Did you follow http://www.gentoo.org/doc/en/gcc-upgrading.xml ? You can't just be randomly compiling apps with 3.4 and then 4.1 and expect things to work... Plus we need some steps and code to reproduce the problem.

I works with qt-4.1.4 from trolltech(no portage) and mysql-4.1.21
Unless you provide us with the application to reproduce the problem, there's nothing we could here.
