>>>>> "unixmania" == unixmania <unixmania@gmail.com> writes: > From: Carlos Santos <unixmania@gmail.com> > Some installations mount /tmp with the 'noexec' option, which prevents > running the program generated there to check the kernel headers. > Avoid the problem by generating the program under $(BUILD_DIR), passed > as the first argument to check-kernel-headers.sh. > We could globally export a TMPDIR environment variable with some path > under $(BUILD_DIR) but such solution would be too intrusive, depriving > the user from the freedom to set TMPDIR at his will (or needs). > Fixes: https://bugs.busybox.net/show_bug.cgi?id=12241 > Signed-off-by: Carlos Santos <unixmania@gmail.com> > --- > CC: Cerem Cem ASLAN <ceremcem@ceremcem.net> > CC: Thomas Petazzoni <thomas.petazzoni@bootlin.com> > --- > Changes v1->v2: > - Move the change that introduces a trap to remove the temporary file to > a separate patch. > - Improve the commit message. > Changes v2->v3: > - Move the SOB line above the cut line. Committed to 2019.02.x, 2019.05.x and 2019.08.x, thanks.
