This will cause problems with qemu so please fix the value (as root) This is a show-stopper; bitbake refuses to run until it's fixed. However, I don't believe it is useful or required any longer. From my understanding, it was there in the past because QEMU for ARM didn't work correctly unless this system parameter was set as indicated. That was when QEMU was being used during the build to create localization data. This is no longer being done and QEMU is not used during the build process. Perhaps we could eliminate this warning or make it conditional somehow? As is, asking the user to make a system-wide setting as root for something that's not necessary seems wrong. -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------
