Bug 651023

yum remove ccache is a workaround.

The failure is not occurring in Eclipse or the CDT.  I would expect this to fail just the same from the command line without Eclipse up and running.  I am forwarding the bug to ccache as I am not familiar enough to suggest what you should be checking for your local set-up.  If it turns out that that the CDT is mucking with your set-up, then it can be redirected back here again when more details are available.

Could you let me know what the following console commands output for your user:

env | grep CCACHE

ls -lad /var/cache/ccache /var/cache/ccache/tmp

groups

rpm -qV ccache

(These commands should be run while ccache is installed and a new console opened after installing it.)

[pierre@pcpblavy workspace]$ su -c'yum -y install ccache'

As I suspected, this is the problem.  Your ccache dir is set to /var/cache/ccache, but you don't have permissions to that dir (you're not a member of the ccache group).  What I don't know yet why is your CCACHE_DIR set there; /etc/profile.d/ccache.sh should set it only if you have write access to it.

Could you try finding out what sets your CCACHE_DIR to that value?  Do you have any CCACHE_* settings in your shell profile files (apart from /etc/profile.d/ccache.*sh)?  For example if you use bash,

grep -F CCACHE /etc/bashrc /etc/profile ~/.bash_profile ~/.bashrc \
    /etc/profile.d/*sh

This same issue is happening with me on F14. It's not limited to eclipse. Any time ccache is used this occurs.

grep -F CCACHE /etc/bashrc /etc/profile ~/.bash_profile ~/.bashrc

shows nothing. This is a brand new bare metal install of F14.

I messed with permissions of /var/cache[/ccache], but no luck. Have now removed ccache.

Hi, thank for your information


I do not have a ccache.sh file
root@pcpblavy ~]# locate ccache.sh
[root@pcpblavy ~]#

I don't think I've got a CCACHE redirection
[pierre@pcpblavy ~]$ grep -F CCACHE /etc/bashrc /etc/profile ~/.bash_profile ~/.bashrc \
     /etc/profile.d/*sh
[pierre@pcpblavy ~]$ 

(idem for root)



My Fedora install is a yum upgrade from Fedora 13 to Fedora 14
I've tryed to reinstall ccache with: yum -y remove ccache; yum -y install ccache;

sean, you missed one argument to grep: /etc/profile.d/*sh (see comment 6).


(In reply to comment #8)

Maybe your locate databases aren't up to date.  Try ls -la /etc/profile.d/ccache.*sh

> [pierre@pcpblavy ~]$ grep -F CCACHE /etc/bashrc /etc/profile ~/.bash_profile
> ~/.bashrc \
>      /etc/profile.d/*sh

I don't know how this would be possible, the ccache package includes /etc/profile.d/ccache.sh and /etc/profile.d/ccache.sh, and both of them most certainly contain the string CCACHE.  And they had been removed while ccache was installed, rpm -V ccache should have told us about it.  Did you run this grep command while you had ccache installed?

(Requested info still needed.)

That's because you're missing the /etc/profile.d/*sh argument to grep, please pay close attention to end of comment 6.  But nevermind, you posted the whole contents of the profile.d ccache scripts so I've now seen them.

Unfortunately I still have no clue why this would happen, /etc/profile.d/ccache.sh clearly does its CCACHE_DIR, CCACHE_UMASK and CCACHE_HARDLINK modifications if: 1) CCACHE_DIR is non-empty, and 2) /var/cache/ccache is writable, and 3) /var/cache/ccache is a directory:

> if [ -z "${CCACHE_DIR:-}" ] && [ -w /var/cache/ccache ] && [ -d
> /var/cache/ccache ] ; then
>     export CCACHE_DIR=/var/cache/ccache
>     export CCACHE_UMASK=002
>     unset CCACHE_HARDLINK
> fi

I'm out of ideas.  Just one more try: please post the complete output of running the following three commands in a shell as non-root:

bash --norc
[ -w /var/cache/ccache ] && echo "writable" || echo "NON-writable"
[ -d /var/cache/ccache ] && echo "dir" || "NON-dir"


Oh, one more thing, I wonder what's the "su pierre" is for: do you log in as root and then su to a normal user, or do you log in directly as a non-root user?

(In reply to comment #12)
> CCACHE_HARDLINK modifications if: 1) CCACHE_DIR is non-empty

Oops, replace "non-empty" with "empty" in the above.

I got this problem when trying to run configure to build clisp.
  configure:3954: gcc -m64 --version >&5 
  ccache: failed to create /var/cache/ccache/tmp (Permission denied) 

I also am running fc14.
ccache.x86_64 3.1.3-1.fc14
I believe that I was running configure successfully before, then I ran it as root, and then could no longer run it as non-root.

The clisp people sent me to the ccache people who reply:

ccache doesn't write to /var/ccache/ccache without specific configuration, 
which implies you are not running ccache with default values. And this means 
that if you haven't configured ccache, then the distribution or operating 
system you use probably have installed and enabled ccache for you. 
 
So, my guess is that you should send the bug report to your operating system 
vendor.

Ok, running stuff as root will most certainly at least pass the /var/cache/ccache writability check in /etc/profile.d/ccache.sh.  But without specific (non-default) configuration, I still don't know how /var/cache/ccache would afterwards end up writable by the *non-root* user.  And if it's not writable, the configuration in the ccache package really shouldn't end up configuring ccache to do anything with /var/cache/ccache and ccache shouldn't be doing that by itself.  Perhaps the previous ./configure run leaves something behind (config.status?) that points there.  But then again if the error comes from a plain "gcc -m64 --version" command even that doesn't make sense to me (unless something sets $TMPDIR to /var/cache/ccache/tmp).

I'm afraid I will still need exact and complete instructions how to reproduce this (commands, environment, group membership of affected users) on my system before I can do something about it.

We're also experiencing this on F14.  Since it's happening while during an automated compiled of a fairly large program, I'll see if a small test case can be written.  In the meantime, here's some of the environment info along with grep output.  Let me know if you need anything else.

What's the output of "ls -la /var/cache/ccache" (as root, and non-root for a user that is not in the ccache group)?  Is SELINUX enabled and enforcing?  If yes, does it make a difference if you put it in permissive mode?

Here ya go.  User cheiny is not in ccache group.

Created attachment 488911 [details]
Fix candidate /etc/profile.d/ccache.sh

Okay, I've found one reliable reproducer.

1) Log in as root or some other user who has write access to /var/cache/ccache
2) su $nonrootuser # user that does not have write access to /var/cache/ccache
3) Try to build something as $nonrootuser

The problem is that at step 1), /var/cache/ccache is writable so the profile.d script sets up CCACHE_DIR and CCACHE_UMASK, and nothing touches them in step 2), so the settings persist but the user still doesn't have permissions to /var/cache/ccache and thus things fail at step 3).

Please test the attached ccache.sh script (drop it to /etc/profile.d overwriting the existing one) and let me know if it fixes this for you.

I'm trying that now.

By the way, I forgot to answer the SELinux question in my last comment: it's disabled.

That seems to have fixed it for us.  Both the simple command line compile example from Comment #19 and compiles through CruiseControl work now.  We had to kill and restart the CruiseControl service, but that makes sense given your explanation.

Thanks!
