[Buildroot] [Bug 12241] Permission denied while running "make"

--- Comment #1 from Thomas Petazzoni <[email protected]> --- I'm afraid this does not look like a Buildroot issue, but a system configuration issue on your machine: /tmp is not writable by the user with which you're doing the Buildroot build. Could you try to just run "touch /tmp/foobar" ? I guess you'll get the same Permission denied issue. If it's the case, then you have to fix your system /tmp permissions.

--- Comment #2 from Cerem Cem ASLAN <[email protected]> --- "touch /tmp/foobar" works correctly:

ceremcem at cca-erik:~$ touch /tmp/foobar ceremcem at cca-erik:~$ ls -l /tmp/foobar -rw-r--r-- 1 ceremcem ceremcem 0 Sep 20 03:04 /tmp/foobar

FYI: I've been using this installation for more than 2 years without any issue.

Is your /tmp mounted with "noexec" option? What's the output of the command

mount | grep -F /tmp

--- Comment #4 from Cerem Cem ASLAN <[email protected]> --- Exactly:

ceremcem at cca-erik:~$ mount | grep -F /tmp
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noexec,noatime,size=524288k)

I remounted with "exec":

sudo mount -o remount,exec /tmp

Then compilation continued. Would you consider adding that checking into makefile? (I may provide a patch for that)

--- Comment #5 from Thomas Petazzoni <[email protected]> --- (In reply to Carlos Santos from comment #3)
Good finding Carlos! Is mounting /tmp with noexec a common thing? From a quick Google search seems like a number of people are recommending to do this. Not sure if this is good advice.

But, for this specific case, Buildroot generally puts all its generated contents in $(O), even temporary things. Perhaps we should do the same for this check-headers script?

--- Comment #6 from Carlos Santos <[email protected]> --- (In reply to Thomas Petazzoni from comment #5)

Some people recommend mounting /tmp with nodev, noexec and nosuid options for security reasons. It is pretty common on FreeBSD but it's not default on Linux distros.

I will send a patch for check-kernel-headers.sh to fix this.
