Bug 36487 – distcc Completely Ignores TMPDIR When Set in the Environment

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Steven Elling 2003-12-25 10:53:39 UTC]

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.
  CHK     include/linux/compile.h
  CC      arch/i386/kernel/ptrace.o
  CC      arch/i386/kernel/ldt.o

<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

[Comment 2 Steven Elling 2003-12-25 11:13:40 UTC]

/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

[Comment 4 Lisa Seelye (RETIRED) 2003-12-25 11:59:55 UTC]

Woops, DISTCC_DIR - sorry.

[Comment 5 Steven Elling 2003-12-26 19:14:17 UTC]

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 [e-mail] or should I do it?

Sure, feel free to report it.
