Thread: Geomview and CGAL

    Exclamation Geomview and CGAL

    I'm trying to run a demo of triangulations with CGAL, for this demo I need an application called Geomview which I downloaded and 'installed', however, when I try to run it I get the following error :

    Code:
    /usr/local/lib/geomview/gvx: error while loading shared libraries: libgeomview-1.9.5.so: cannot open shared object file: No such file or directory
    I tried looking for the library libgeomview-1.9.5.so but no look.

    Anyone know how to get around this? Thanks

    The geomview project does not provide exact instructions to install on a rpm distro.
    It'll be important for you to provide the references or guides you used to install, particularly if you built from source.

    Keep in mind that the source was last updated in 2014, current gcc <may> build successfully but might not so you must pay close attention to your build output.

    Took a few minutes looking at CGAL,
    Is there some reason why you want to install geomview since that is so old could pose problems of its own?
    Without being more familiar with the CGAL project,
    It gives every indication you can install that on its own, and you can build all the examples, demos in that as well as the core libraries with less chances of problems... and the CGAL project looks very currently maintained(plenty of submits merged 2 months ago).

    There's plenty of ways described to compile CGAL in the various site and source documentation I skimmed, although all should work my personal preference would be to clone the github repo and run the commands described in the INSTALL.md... Because to me, there's nothing like working off the latest, official copy of source and it's simple to update your build later (run "git pull" and then do the build steps exactly like before).

    I can't find anything that describes using any viewer application like geomview,
    So I suspect might not be necessary.

    Hello, thanks for your time!

    I can run CGAL Just fine on Linux, both Ubuntu and TW, I needed geomview to SHOW some results, ended up using GNUPlot tho, I'll give it a try later when I have more time. Thanks again!

    Hi
    Here you go;
    https://build.opensuse.org/package/s...STING/geomview

    Should be in the repo soon, just download and install with zypper;
    https://download.opensuse.org/reposi...leweed/x86_64/

    Just remember to uninstall your local build first....

    Hope Geomview works for you.
    A quick Google search for a CGAL mesh viewer returns Geomview as the top hits...

    But if it doesn't work out...
    I was curious if something more recent exists, particularly the very popular Blender.
    I only found a couple hits of Blender and CGAL, so either people are using it without a problem and keeping to themselves or it hasn't been tried by many (but there are a few!).
    I found the following which is currently maintained and built on Qt (a fairly modern GUI tools technology), and his most recent release as of this writing is May 2018... And he expressly supports CGAL and other similar libraries. IMO this looks promising, if you try to build this on your own and run into problems, recommend you post in the Development forums.
