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.

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? lisa@gentoo.org 2003-12-26 19:33:47 0000 Sure, feel free to report it.
