Geomview on amd64

Hi,

short background: I want to use MPQC. Computed molecules can be rendered with molrender (included in MPQC). The output is an OOGL file that the Geomview program can read and display.

My problem: I want to install Geomview on amd64, but it is only available on "~x86 ~sparc ~ppc".

I just want to make sure, if I understand this correct: if I want to install Geomview on amd64, I have to install it in a 32-bit chroot environement as described here, right?

Since this is heavy stuff just for one application: is there another way to display the computed molecules of MPQC on amd64? I googled a little bit, but did not find any obvious solution.

Thanks for any help
Marc

If I were you, I'd try and compile it on amd64 as a first,
just ekeyword amd64 <package-name> and ebuild <package-name> digest && emerge.

Works for some packages, dunno about this one though...

You mean add "sci-mathematics/geomview ~amd64" to /etc/portage/package.keywords and then run

Code: Select all

ebuild <path-to-geomview-ebuild> digest && emerge geomview

, right?

Why the "ebuild ... digest" command? I read in the man page of ebuild, that this command checksums all download files. Why do I need this here?

Regards,
Marc

When you edit any part of the ebuild, including the ebuild itself, it's good practice to rebuild the digests. There is always the chance that it might think the ebuild was damaged in transit through the rsync. I've had some work without rebuilding them, and some that didn't, but i've learned to do it every time regardless.

Ok, you mean to change the ebuild (add amd64 keyword), digest it, and emerge it.

I did this and it compiled without errors. In the afternoon I will test, if I can work with the program. The amd64 computer is at another location then my PC...

Thanks
Marc

I get the following error, when I start geomview:

Code: Select all

zweiundvierzig mblume # geomview -opengl /usr/data/geom/tetra
Error: Can't open display:

tetra is an example file geomview. Looks like it does not work, so think just compiling it on amd64 does not work.

Does anyone know about another tool looking at OOGL files?
