I just built and set up 3.1.0 and htmlgend keeps crashing on startup with a sig 11. What does that mean? Here are the logs:

| Have you defined extra user images in a conf file but forgot to add the source for them back into the new 3.1.0 source tree? This is the common reason for such behavior - you are references user image function indexes for functions that don't exist... |

| Nope, I didn't touch the images config, nor did I change either 3.x source code when I built it. What else could it be? |

| images-user.conf and images-user.c are the files I'm referring to. If the conf file references functions you didn't add back to images-user.c, then it will segfault. No idea beyond that... |

Have you tried moving all your config files in /etc/wview and all your data in /var/wview to a safe place and doing a "make install-env", then trying to run wview? And using a standard prefix during configure?
If it runs when your custom config is out of the way, then it is something in your configuration causing it - like indicated above. |

OK, I've put everything back as the default and it works now.
Specifically, I rebuilt radlib and wview with no --prefix setting and use /var/wview instead of a custom data directory. (I never put any configs outside of /etc/wview.) No more being fancy from me. 
So to everyone else, fight the urge to install things somewhere other than /usr/local. You will have trouble if you don't. |

No, you can install it other places. Many folks do. I just don't recommend using something like "/software". I can almost guarantee you you had customized something that was causing this crash. If it starts and stops via your (obviously modified since you are installing in a non-standard location) wview script, then it isn't going to crash because of where it is installed. There was something custom in your setup, images-user, etc.
Having said that, /usr/local *is* for locally built/installed software.
I just saw the bit about not using /var/wview - that could have been a problem and you didn't divulge that earlier. Why does program data need to go somewhere other than /var, where it is supposed to go? That certainly qualifies as customizing something.
/etc/wview and /var/wview locations should not be dorked with. Install in non-standard locations with caution, understanding what all it effects. |

You are going to have to explain this one. How is /software not "other places". It's other than /usr/local or /usr. If I put it in /opt, how is that any different?

The only thing I changed were variables included in the config file. I did not hack any code or move anything that wasn't defined somewhere.

Agreed, that's a good place to put things.

Yes, good information and I should have included that. But my initial question was to find out what a sig 11 was since I don't know enough about C to go and find out. If it meant "can't find config dir" or something, I would have known I screwed it up.

In my opinion, data not associated with the operating system should not be stored in an OS system directory. (I'm not saying you are wrong for putting it there, it is just one way of thinking.) For example, Windows 98 should never have stored the user's My Documents folder inside the Windows directory. (XP puts it outside where it belongs.) So I wanted to store my img and archive directory elsewhere. The rest of /var/wview was untouched. Again, I would have never moved it if there wasn't a variable in a config file defining where such stuff goes.
Nor am I asking you to change things. Having to set up a data directory and all that just leads to more posts in the troubleshooting forum. But the program shouldn't break if the variables are properly defined as they were for a working 3.0.0 installation. This leads me to believe that it is possible that something is not using the variable defined in the config file.

I don't plan on dorking with it anymore. Consider me a standard installation. |

I'm sorry, but almost every application known to unix stores its run time data in /var. /var is in no way synonomous with the "windows" directory. Find database files, ntp files, and a host of other application data files in /var.

Sig 11 is a unix signal - specifically SIGSEGV (segmentation fault). This means the program crashed and may have produced a core dump. This is general unix stuff, not associated with C or wview in particular. If any unix process segfaults, it is a big problem. |

I agree. I'm not exactly saying /var is like the Windows directory, but that's a topic for another time.
I was coming at wview like an application taking data and processing it. Where I work, people analyze data in their own separate data partitions and the apps never write anything in a system directory.
But looking at it differently, I now see wview is part of the OS that has a specific purpose, to take weather data, process it and post it to the web, etc. Sort of embedded. That's all my wview PC is doing. Nothing else. So I don't have to think like I do at work, so I'll stop being a nuisance.  |
