Re: [Starpu-devel] Issues met during installing and configuration of StarPU

[Samuel Thibault <samuel.thibault@labri.fr>]

Hello,

When reporting an issue, please

- always keep the mailing list in Cc, so that I am not the only
recipient of the mail. Writing to me only means risking falling in the
middle of my vacations and thus not getting an answer for weeks, or that
I just don't have the time to answer and thus you would at best get a
terse answer, or worse, no answer at all... Conversely, keeping the list
in Cc means avoiding all these issues completely, you'll involve all the
community to help you, make the answers you get available to everyone,
and even archived for web crawlers to find them whenever somebody has
the same issue.

- always give a full log of what you ran and all messages, as well as
the content of config.log, so we have an idea of what happened, and not
only the last piece of the puzzle, because

with only that information, I just have no clue.

No, it's supposed to be shipped by the .c file next to it. But without
the make log, I can't know what happened.

What do you mean by "needs multiple cores"? Which examples are they
exactly?

What did you do?

What did you get?
