Re: [yocto] QEMU Size Increase from Yocto Thud to Zeus
Hello Ross, Thanks ! I was able to reduce the size of the image by modifying the QEMU_TARGETS variable.. but on enabling buildhistory and checking under installed-image-sizes.txt , the individual package size of the qemu remains the same. Is this correct? If not is there any other optimization that can be done?

[yocto] Python2 in Gatesgarth
Hello Developers, We are migrating our platforms from Zeus to Gatesgarth, We could see that the native Python2 bb file and core modules have been removed. As much of our platform code is in Python2, I was wondering if there is some way we can re-enable python2 support in our yocto environment to compile/run python2 scripts ?

Re: [yocto] QEMU Size Increase from Yocto Thud to Zeus
Thanks for the clarification, yes I am installing QEMU in my image. Is there some way that we can disable the additional architectures and streamline the size ?

[yocto] QEMU Size Increase from Yocto Thud to Zeus
Hi Experts, I am upgrading my Linux from Yocto Thud to Zeus (5.4 Kernel) . After building I could see a significant increase in the size of the image. On checking with buildhistory enabled, I could see that qemu has nearly doubled in size. Thud (4.19) - 223084 KiB qemu Zeus (5.4) - 474757 KiB qemu Is this size increase expected or are there some additional configs that might have been added as a part of the upgrade ? Appreciate your help. TIA, Aashik -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[yocto] Disable/Enable DHCLIENT in Yocto
Hi Developers, I am trying to add DHCLIENT package to my Yocto Zeus Build. However If we include "dhcp-client" package in yocto, the dhclient takes the priority over existing Busy box udhcpc and starts during the init. My box basically uses UDHCPC for getting the IPs and my intention is to install dhclient only on a need-to-use basis. is there a way where we can prevent DHCLIENT to run on init unless invoked manually ?

[yocto] Perl-Native compilation for THUD in Red Hat 8
Hi Developers, I recently migrated my machine to Red Hat 8 , I am using Yocto Thud to build my customized yocto image. However, I am seeing the following Build Issue while compiling Perl-native /usr/include/errno.h:48:10: fatal error: bits/types/error_t.h: No such file or directory | #include | ^~ | compilation terminated. Is there a way that this dependency can be moved to Yocto itself, or is there some alternate way we can try out.

Hi Leon, Zoran
I am using Ctrl+C to kill the Ping command.
Thanks.

[yocto] SIGINT Issues with Zeus Migration
Hello Developers, I recently migrated all my platform Recipes from Thud (Linux 4.19) to Zeus (5.4). I understand there might be compatibility issues and was able to fix most of them. However one issue I am facing is that in the newly migrated Zeus Image is that I am not able to send SIGINT to commands such as Ping, tail etc. I am only able to run them in non-interactive mode. I have to reboot the box if I executed those above commands in interactive mode. Can anyone suggest which recipe/config can be a good starting point? Please let me know your suggestions.

[yocto] RootFS Size increase during Migration
Hi Developers, I am migrating my code from Yocto Thud (4.19) Kernel to Yocto Zeus (5.4) Kernel. The recipes and conf files are essentially the same, but I am seeing a substantial increase in the RootFS Size and Subsequent final image size (Close to 40 MB). Any idea on how we can debug this or where we can start for inspecting why the image size increase. Thanks, Aashik -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
