[gentoo-science] opendx & opendx-sample

[François Bissey]

Hi all,

For anyone interested in using opendx I just pushed a new revision
of it in the overlay along with a new revision of opendx-samples.
In this revision I changed the installation location layout to be a
bit more reasonable.
I initially tried the scheme used in fedora but it required a link 
between /usr/share/dx and /usr/lib(64)/dx, plus it was still potentially
broken even with the link, so I scraped that.
Most of the stuff now goes under /usr/lib(64)/dx except the 
doc, man page and headers which goes which where you expect.
opendx-samples had to be updated to match the new location and
I replaced the installation hack by a patch.
There is still a minor issue to solve properly with szip but I would like
some feedback from the current change by interested users before 
going further, I also spent a week perusing opendx code and need a small
break from it.

Cheers,
Francois aka kiwi_fb

Hi,

thanks for your hard work!

I think there is a problem with parallel make processes. If I try to emerge 
opendx-4.4.4-r2 with MAKEOPTS="-j3" it fails with

With MAKEOPTS="-j1" it compiles and installs fine.

Hi Frank,
we already have a patch for that but for some reason it doesn't always work.
And I think I know why and I thought I had it solved but obviously it wasn't
enough. I will see if the solution I think for it works in the next 12 hours.
For info the patch is concurrent-make-fix and it use to apply to local.mk
unfortunately this file is meant to be generated from local.mk.in so it can
be overwritten I changed the patch to local.mk.in but that's obviousvly not
enough to ensure it is always generated correctly. I will remove the extra
local.mk that shouldn't be in the tarball in the first place and see if it 
really works without problem.

Cheers,
Francois

Turns out I had forgotten to update the concurrent-make-fix patch
with my change from local.mk to local.mk.in . To make sure there is
never any problem with it ever I now patch both.

That problem should be sorted for good now.

Cheers,
Francois

Thanks, will try it out later!

And also thanks again for your work and fast reaction!
