Qt5.15 crosscompile error cannot find Crt1.o, crti.o, crtbegin,-lstdc++

Hi,

Am trying to cross-compile Qt 5.15 using below configure line and yocto sdk:

Hi,

I might be wrong but doesn't yocto already provide support to build Qt SDKs ?

[Ramakanth]

Yes with yocto recipe, it gives below errors:

There might be a misunderstanding between the two of us. Are you trying to cross-compile Qt 5 yourself or are you using a yocto recipe ?
