      @SGaist That was my problem. I compiled the libraries with MinGW 32 while my Qt's is MinGW 64. I changed the compiler and the problem is solved. Thanks for the help.

      Hi, welcome to the forum. This package does not contain static Qt libraries. The .a files are used to ease the dynamic linking. On Windows there are two ways to use dynamic libraries. The first one is by calling LoadLibrary (or using QLibrary that wraps it) at runtime. It's not convenient because you need to resolve all the symbols manually this way - lots of pointless work with a huge library like Qt. The other way (preferable and used here) is to link to a library that will load and resolve the shared library (dll) at runtime for you. The .a files you listed are just that. You link to them and you still need the dlls at runtime. As for how you use them: When you create a project in Qt Creator , in your .pro file you add the modules you need in the QT variable, for example: QT += core gui widgets network. After that you just run qmake (Build->Run qmake). This handles all the linking to the right .a files for you. To have a static build (without the dlls) of Qt you need to build it manually from source package. Be aware that there are licensing restrictions for the open-sourced version of Qt when linking statically.

      It is not a qserialport issue, it is a kernel/driver issue. A driver of your serial port has bugs, you should try to update driver or to use another HW device.

      @SGaist Thx I will give it a try. I am closing it as solved since the issue has been reported for bug-fixing and there are other options to make it work.

      It's more of a limitation than a bug I think. To OS, by default a window is a rectangle, no matter how you paint it, and stylesheets are just a way to paint it. To cut out the corners you would need a mask. Something like: auto frame = new QWidget(parent, Qt::Popup); frame->setStyleSheet("background-color: red; border: 1px solid green; border-radius: 6px;"); QPainterPath path; path.addRoundedRect(frame->rect(), 6, 6); frame->setMask(path.toFillPolygon().toPolygon()); frame->show(); The problem is that the mask is a bitmap (0-1), not an image with alpha, so you get a jagged edges, but for some radii it works pretty well.

      I also tried this on my Win7 machine but never succeeded. In the end I did a local compile on my RPi2 of Qt5.5. It compiled for 1041 minutes but is working nice now. I followed this guide for the local build. Instead of 5.4.1 I just got the latest source. Could also be an option for you.

      Hi and welcome to devnet, Not necessarily the answer you are looking but the guys here are providing 64 bit MinGW builds of Qt. Hope it helps

      I'm glad you got it working. For the future, I wouldn't recommend copying the dlls to the windows system directory. Check out this page for deploying on windows. In particular check out The Windows Deployment Tool section. Paul
