Hi Richard, I meet 2 problems about nativesdk-perl. First one is that nativesdk-perl-modules doesn't depends on the single nativesdk-perl-module-xxx which I asked you yesterday, but I still don't know how to fix it. I tried to add one line to perl_5.14.2.bb: RRECOMMENDS_perl-modules_virtclass-nativesdk += "nativesdk-perl-module-config" and it will cover the original value and make nativesdk-perl-modules only depends on nativesdk-perl-module-config. Doesn't "+=" work for nativesdk ? The second issue is the latest commit for perl(Yocto commit 876ec81c039132d07a5f3d99bae40d6154351d41) . I build meta-toolchain-gmae with it, and the perl @INC path remove the "/opt/poky/1.2+snapshot/sysroots/x86_64-pokysdk-linux" prefix. Is that the right operation? Regards, Kai
