Hi All,
Thanks much for supporting with quick responses that is getting us unblocked!

Here I am with yet another such road block, which needs your guidance:

If insist on not using any of these, bypass this error by defining XML_POOR_ENTROPY; you have been warned. If you have reasons to patch this detection code away or need changes to the build system, please open a bug. Thank you!

I assume you tried it ?

@frollic , Can you please suggest the location where we should be defining XML_POOR_ENTROPY, coz all we did was enable the package in make menuconfig, and not sure if we should be editing expat's configure file to enable /define XML_POOR_ENTROPY.

googled XML_POOR_ENTROPY ?

Wonder if this is my fault :slight_smile:

edit: oh wait this is 21.02. nvm.
