Hello Everybody,

I am trying to compile the netgen scources from
http://www.hpfem.jku.at/netgen/
on a Fedora Core 6- System without success. after setting the Environment variables and adding the
missing line in meshtype.hpp (class mesh;), as described in the OF-Message Board thread "Installation of Netgen in SuSE Linux 9.2" I still have problems compiling the togl- module receiving the following error messages:

Hi Jan,

you can find useful info on some forums. Just type something like "netgen togl fedora" on google and you can find what you need.

However, I managed to compile netgen. If you have an ftp site I can upload there my modified version.

Bye

Tommaso

Hello Jan,

A Good day to you!

I have been using Netgen since Fedora Core 5 (currently running on Fedora 7, and will be shifting to Fedora 8).

I am currently at work, but once I get back home this evening, I can give you the settings I use for compiling netgen from CVS.

I recompile netgen quite often, so we should be able to solve the problems you have.

Enjoy!

Philippose

Hello again,

I think Tommaso's idea would be the best in my case too... I have made the required modifications for compiling Netgen v4.5 on Fedora 7, and have also enabled the OpenCascade support which allows for the import of STEP/IGES data.

It might be easier to just zip it up and post it somewhere rather than trying to explain the process (unless you really want to know :-)!)... its not too complex at all...!
