Description SpanKY gentoo-dev 2012-04-21 07:10:17 UTC 
when PORT_LOG_DIR is active, would it be possible to still deploy a symlink at $T/build.log that points to the real log and include that in the die error message ?  this way you have a static path that doesn't change in between runs of the same version.

create symlink to PORTAGE_LOG_FILE in ${T} and display in die message

Note that it's ${T}/build.log.gz if FEATURES=compress-build-logs is enabled.

The path to PORTAGE_LOG_FILE is also displayed by the emerge status display, so that it's easy to locate logs for failed builds while emerge is still running due to --jobs or --keepgoing:

>>> Emerging (1 of 1) portage-test/die-test-1
>>> Failed to emerge portage-test/die-test-1, Log file:
>>>  '/var/log/portage/die-test-1:20120421-183524.log'

Do you want to change the path that's displayed there too, or just in the die message?
Comment 2 SpanKY gentoo-dev 2012-04-22 15:10:39 UTC 
just the normal verbose `die` is OK.  this makes it easier on people who `emerge foo`, do stuff, `emerge foo`, do stuff, etc... to have the same path to the log in between runs.

if you wanted to include both paths in the `die`, that'd be fine too.
Comment 4 Zac Medico gentoo-dev 2012-04-23 00:01:35 UTC 
This is fixed in 2.1.10.57 and 2.2.0_alpha101.
