If your are compiling a yocto rootfs and at the very end of compilation, you might face an QA error while creating the final rootfs, which could look like below,
ERROR: QA Issue: File '/usr/lib/libqwt.so.6.0.1' from qwt was already stripped, this will prevent future debugging! [already-stripped]
To fix this error, Add INSANE_SKIP_${PN}_append = “already-stripped” to your local.conf file,
where ${PN} is the associated package name.
Hence a fix to above error will look like addition of following line to local.conf
INSANE_SKIP_qwt_append = "already-stripped"
or type below command to append conf/local.conf
$ echo "INSANE_SKIP_qwt_append = \"already-stripped\"" >> conf/local.conf
