The Above build environment is WSL2 ubuntu 20.04
WSL2 could be the decisive information, similar/same failure was already reported, see [1], the fix/workaround is accepted/committed upstream, see [2], and should be in buildroot after latest genimage version bump (see [3]), not yet in 2021.02, only on git master... [1] https://bugs.busybox.net/show_bug.cgi?id=13146 [2] https://git.pengutronix.de/cgit/genimage/commit/?id=4c2b02df0861e06ca9320d80ad60994d4a239ad6 [3] https://git.buildroot.net/buildroot/commit/?id=50cfedc86d205f2ac7145deadb1c94474374acff
(In reply to Peter Seiderer from comment #2) > similar/same failure was already reported, see #13146 But 13146 was about WSL1, no? That error is not supposed to hapen under WSL2, as I understand it... NirajTummala, are you sure you are using WSL2? Care to double-check, please? > latest genimage version bump (see [3]), not yet in 2021.02, only on git master... Could you please send a patch for 2021.02 with just a backport of that fix, please? (yes, I know I was not in favour of it back then, but since upstream did apply it, then we can backport it now). Thanks! Regards, Yann E. MORIN.
yes i am using WSL2 on latest Windows OS build Thanks, niraj
