Apparently lib/rst/qtree does not compile in parallel make mode (make -j4) - see error above. How can this be serialized in the Makefile?

comment:2 by neteler, 9 years ago

Resolution: → fixed
Status: new → closed

Problem is gone, closing.

comment:3 by neteler, 7 years ago

In 71343:

librst: to prevent parallel (really rare) compilation failures, data dir must be processed before qtree (trunk, r71236). Probably fixes #2265

in reply to:  2 comment:4 by neteler, 7 years ago

Replying to neteler:

Problem is gone, closing.

Likely fixed in r71236. Backported to 7.2 in r71343.
