RDEPENDS is for runtime dependencies specific packages and thus has _<package name> as suffix ($PN = bar in this case). libfoo gets compiled because of this entry, but because it is a runtime dependency, compilation of bar doesn't wait for libfoo's completion. -- Best Regards, Patrick Ohly The content of this message is my personal opinion only and although I am an employee of Intel, the statements I make here in no way represent Intel's position on the issue, nor am I authorized to speak on behalf of Intel on this matter. -- _______________________________________________ yocto mailing list [email protected] https://lists.yoctoproject.org/listinfo/yocto
