[yocto] Installation of i686 SDK on a x86_64 machine?
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? Thanks in advance.

Use -f to force installation. Thanks, Laurentiu Thanks in advance. Best regards, Wolfgang Denk ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto

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 Sorry, but this bug is about a different problem - the fix overshoots the mark. The following combinations of SDK_ARCH and INST_ARCH are possible and relevant here: Id SDK_ARCHINST_ARCH Status == 1 ix86ix86works 2 ix86x86_64 works 3 x86_64 ix86cannot work 4 x86_64 x86_64 works The bug report is about case 3 - attempting to install a 64 bit SDK on a 32 bit machine. This indeed cannot work and shuld be prevented byy the installer. But the current code also prevents case 2, installing 32 bit images on a 64 bit machine, which works perfectly fine (assuming you have the needed 32 bit libraries installed). For any distribution it is very convenient to provide only one set of images (configured for ix86), as these images will work both on 32 and 64 bit systems. I consider it a major drawback if you intentionally prevent such use.
