Re: haddock failure during validate on os x

1 May 2013

      Thanks Geoffrey.

It looks like the links that are created by lndir (i.e.
in utils/haddock/resources/html/Ocean.std-theme) are fine, even when
invoked with a relative fromdir.

It seems that things go wrong when those files are copied over to
inplace/lib/html/Ocean.std-theme. The links are still relative, but the
depth of the files has changed, so now the original relative paths aren't
correct. This may explain why it works alright when you use an absolute
fromdir with lndir.

I had this same problem. If you use a build tree, invoking lndir with an
absolute rather than relative path fixes things (for me).

This seems to be caused by running "sh validate" in a build tree setup
per the instructions
here http://hackage.haskell.org/trac/ghc/wiki/Building/Using  .  I
re-ran "sh validate" in my source tree, and it went through OK.
Is this expected, or should validating in a build tree be supported?

Hi all,
I'm trying to validate a bug fix for the IO manager on mac os x,
    but when I run validate I am running into a problem due to
    haddock.  I see what the problem is, but I'm not sure where I
    should go to fix it. Here is what happens:
Validate fails when it gets to the following command:

It seems to be trying to link
    to utils/haddock/resources/html/Ocean.std-theme/hslogo-16.png in
    my source tree.  But the problem is that there is one too many
    ".." in the links.  If there were one fewer ".." in the path, then
    it would work fine. Do you have any idea how to fix this or where
    the bug might be?
Cheers,
-Andi
