[yocto] Yocto and Qt embedded

[Zhang, Jessica]

Hi Giovanni,

You need to build a matching toolchain.  Either from command line do "bitbake meta-toolchain-qte or through hob, under Settings, please make sure check "Build Toolchain".

Thanks,
Jessica

These names are OK for the Qt Embedded libraries, and they should match what your cross development tools are using.  Which tool chain did you use for compiling and linking your application - the one from meta-toolchain-qte ?

When I build meta-toolchain-qte, this also includes, for example,

.../sysroots/armv6-vfp-linux-gnueabi/usr/lib/libQtGuiE.so.4.8.2

so cross tool chain and native systems work together without problems.


Best regards,
