Could we see the last few lines of the logfile just before a crash?

I can't see much of a clue here........

Thomas....
Thanks for the logs.

Could it be that it doesn't like the blank spaces in the filenames? Or path?

I'll test this some....

I renamed it in the last log excerpt (no spaces) and later I moved the renamed directory to the "normal" place where the other Swedish charts are. No change, still a crash.
In most runs (except one) OpenCPN seems to load quite a few charts before the crash comes. I would hazard a guess that it is the spaces in the file names, and exactly how Linux handles them. Maybe some obscure buffer overflow ??? Personally I try to avoid spaces when naming files and directories, out of habit, as this used to(!) create problems......

It looks like I have opened a real can of worms, ....Fixing Unix/Linux/POSIX Filenames: Control Characters (such as Newline), Leading Dashes, and Other Problems
I've only skimmed this page, but I would not be surprised if the answer is there somewhere.

Maybe this has to be handled with a rewrite of filenames on the fly in Linux..?

Wheeler mentioned "detox" as a utility that already existed, to clean up filenames for linux and other *nix. Detox is written in C and Yacc and has a BSD license. I downloaded and tested. First a dry run using

detox -n File_with_swedish_charts > outfile

See attached files. This shows what detox suggested to do. Space becomes "_", "(" and ")" becomes "-", "å","ä" and "ö" becomes "a","a" and "o", etc. So I went ahead, let detox change the filenames, and as expected OpenCPN had no more problems.
Sugestion: Instead of reinventing the wheel, use detox, one way or another, for posix-like systems. Link here detox software at SourceForge

Another unusual calibration today. A privately scanned tmerc chart that was far from perfectly scanned and needed a skew correction of about 3 deg to be correctly aligned. Whatever I did, the georeferencing was way out. I read values on the chart that was outside the "PLY-square" !!! Calling the chart a "Mercator" instead, made the georeferencing reasonable. So I draw the conclusion that OpenCPN presently can't handle a skewed tmercs. I only saw the "skew" icon on the button, never the "tmerc" icon.
As a matter of fact the PLY outline was correct but the lat&long values read inside this outline were way off, and as soon as I tried to move around I was sent to the indicated position off the chart.

Downloaded the 2.1 but have one problem, cannot switch between ENC charts and CM93, no longer a choice on the page bottom and so all I have is CM93 in the window. Can anyone help?

[cagney]

marknewman

Have you loaded the Enc:s?
Are you trying in an area where there are ENC:s?
If the answer is yes to these two, please let us have a look your log-file.
