Re: Building Qt5 toolchain for windows

Hi,

Our changes for supporting mingw builds for Qt5 nativesdk tools are still part of the meta-boot2qt layer (https://code.qt.io/cgit/yocto/meta-boot2qt.git/), which is used in the Qt for Device Creation product. Some of these changes could be moved over to meta-qt5. CMake support is still partial and will only work with the Qt Creator integration.

Hello Joshua,

 

Thank you for your reply,

 

Just for information, I put the following parameters in local.conf

 

MACHINE ?= “qemuarm”

 

SDKMACHINE = “i686-mingw32”

 

IMAGE_INSTALL_append = “ gcc g++ binutils libgcc-dev libstdc++ libstdc++-dev libstdc++-staticdev qtbase qtcharts qtconnectivity qtdeclarative qtenginio qtgraphicaleffects qtlocation qtmultimedia qtscript qtsensors qtserialport qtsystems qttools qttranslations qtvirtualkeyboard qtwebsockets qtxmlpatterns openssh-sftp-server gdb gdbserver”

 

And here is the error I get when I run the command: bitbake meta-toolchain-qt5

Hello,

 

I’m working on a project and I need to build a Qt5 toolchain for Windows,

I’m using meta-qt5 and meta-mingw and my build machine is an ubuntu 18.04

However I keep having errors when i execute « bitbake meta-toolchain-qt5 », very much like the one in below forum thread 

https://www.yoctoproject.org/pipermail/yocto/2019-March/044512.html

 

Am I doing something wrong ? Could you help sending me some ideas on how I could accomplish what I want ?

 

I don't actually know a whole lot about cmake/qt5, so I'm not sure what would need to be done (other than what I've already stated in the message above). Samuli Piippo (cc'd) recently did some work to get cmake to build for MinGW, so he might have some insight.

 

Thanks,

 

Best regards,

David Fourdrigniez.
