Need help installing BRL-CAD

[Guest]

I've been struggling for a few days to get BRL-CAD installed on Kubuntu 9.10. I've tried downloading the binary and source tarballs. The install instructions are not very clear. I understand that the directory should end up being /usr/brlcad but they don't specify whether the make / make install process will put it there. There seem to be some errors during the make process but it doesn't explicitly fail. Does anyone have any experience with this?

Re: Need help installing BRL-CAD

First, which version did you download from SourceForge.net > Find Software > BRL-CAD > Browse Files

The installation will create the /usr/brlcad directory. That the make process throws errors is important. What are the errors (or warnings). Scroll back through the output and note them and let us know.

This implies that you didn't download a binary, but instead, downloaded the source for compiling. Why? There is a linux (cross-platform) binary that can be downloaded from the link above.

What can BRL-CAD do that Blender's feagtures don't include? And Blender is in the repository!

been a long time since I looked at brl-cad so I don't know what is and isn't there, but there are differences between solid modeling and mesh modeling. And there are disciplines that are better suited for solid modeling.

in short: blender is to artists as brl-cad is to engineers.

The only thing different is that I am on the 64b Kubuntu and I use "binary-amd64" instead of "binary-i386".

Bug on the 64b platform? Seven out of 12 Google responses to "sh "getcwd failed" No such file or directory" show bug listings.

Re: Need help installing BRL-CAD



The dpkg-scanpackages is a perl script and the getcwd() is a perl function (get current working directory). Are there other perl problems ?


Installation & fix

Alternative (without adding the PPA as a repository) is to use the dpkg to install the packages and then fix the installation with the "apt-get install -f".

Re: Need help installing BRL-CAD

sudo dpkg -i * did it! The "fix" apparently wasn't necessary because it didn't do anything.

Now I'll spend some time playing with it.

Thanks, Rog131 ! 8)
