Hi Andrew,

Thanks for finding that thread. The problem we are having is that paths

specified in RELEASE are no longer fully respected with the change to

Path.pm in base from that thread.

By that I mean that we specify the exact path that we want to be used

for finding each module, but the addition of the abs_path() step forces

that into an undesirable (for us) canonical form. The paths we

explicitly specify are designed to work across all our servers

throughout our environment. The canonicalized forms include mount

points, volume names, and so forth that break when we move from a build

server to a production server.

Besides the unpalatable option of hacking our Path.pm to get the old

behavior, Scott has found a workaround whose side effects we haven't

fully characterized yet. It involves removing the fullPathName.pl step

from the definitions of some variables (e.g., SHRLIB_DEPLIB_DIRS,

PROD_DEPLIB_DIRS).

We'd like to work out a solution that solves our problem (respecting

paths specified in RELEASE) and doesn't break the fix for the original

problem, but I'm not quite clear on what the original problem was.

How does convertRelease.pl break when handed relative paths? I can't

seem to make it do that in 3.14.12.3. Perhaps that issue was fixed by

another change? Angus?

Thanks,

Hi Scott,

Please read this tech-talk thread to see why the line you want removed was added:

Could you use the INSTALL_LOCATION Makefile variable to set the canonical installation path in your CONFIG_SITE file? If the build machine can write via either path then that might solve the problem. If not there may be other ways to get around this if you can explain a little more about your setup and process.
