Bugzilla Bug 36487

First off I use NFS for my home directories and locks cannot be created in
distcc's default location (~/.distcc).  I have no ideal why NFS locks are not
working because I am using the kernel nfs service on my Gentoo server.

I use ccache and distcc to compile my kernels as a normal user and set the
environment variable TMPDIR to /tmp to prevent distcc from using my home
directory, however, it appears distcc is completely ignoring TMPDIR.

Reproducible: Always
Steps to Reproduce:
1. Mount your home directory from an NFS server.
2. Change the permissions of a kernel source tree under /usr/src so a non-root
account can compile the kernel.
3. Configure the kernel.
4. export TMPDIR=/tmp
5. export DISTCC_HOSTS="localhost host2 host3"
6. make -j5 HOSTCC='ccache distcc' CC='$(HOSTCC)' bzImage

Actual Results:  
This is some of the output (edited to remove account name) from a 2.6.0
compile:

make[1]: `arch/i386/kernel/asm-offsets.s' is up to date.

<snip>

Expected Results:  
distcc should of created the locks under /tmp and then distributed the compile
to other distcc hosts.

set DISTCC_DIR in make.conf

/etc/make.conf has nothing to do with running make -- independent of the
portage system -- inside the kernel source tree.  make.conf is only used during
an emerge and obviously I'm not running emerge.

You want to use DISTCC_TMPDIR

Woops, DISTCC_DIR - sorry.

Ah, ha! DISTCC_DIR worked.  The distcc man page states:

TMPDIR - System temporary directory. distcc creates a subdirectory whose name  includes the hostname and userid inside this to store all its files. By default /tmp/ is used.

Should I let you guys file a bug report with distcc@lists.samba.org or should I do it?

Sure, feel free to report it.
