Hi,

in previous releases it ha always been possible to install a SDK
configured for a i686 machine on both x86 and x86_64 systems.

Since commit c04f5435 "populate_sdk_base.bbclass: use SDK_ARCH instead
of SDKMACHINE" this does not work any more; instead, installation will
abort with "Error: Installation machine not supported!"

++ uname -m
++ sed -e 's/i[3-6]86/ix86/' -e 's/x86[-_]64/x86_64/'
+ INST_ARCH=x86_64
++ echo i686
++ sed -e 's/i[5-6]86/ix86/'
+ SDK_ARCH=ix86
+ '[' x86_64 '!=' ix86 ']'
+ echo 'Error: Installation machine not supported!'
Error: Installation machine not supported!
+ exit -1


Is this intended behaviour (and if so, why?) or rather a bug that
should be reported and fixed?

This is the intended behavior. Please check:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=3269

Also, this thread:
http://lists.linuxtogo.org/pipermail/openembedded-core/2012-November/031519.html

If people really need to install SDK tarballs intended for other hosts
than the SDK was built for (i686 on x86_64 or vice-versa), we could add
a -f flag to force installation and show an error message like this:

"Error: Installation machine not supported! Use -f to force installation."

Thanks,
Laurentiu

Thanks in advance.

Best regards,
