Having issues running on WSL2 on Windows 11

I installed astrometry version 0.95 from the tarball, did the make files, and downloaded the fits files. Every so often, it appears to run correctly, but does not generate a png file so I can see what it found.

So for example, I uploaded the image and solved it on the web, which did solve:
Submission 9936706
Image 10084434
File name: djs_2024_05_27_0000.jpg

Command was:  solve-field djs_2024_05_27_0000.jpg

Here is the sdtout (not verbose):

On some some other images I get what I need  for pngs.  What am I doing wrong?

Thanks

Hi,

The error message " Netpbm is not available; can't read PPM images" means that it will not be able to make plots (internally, it converts everything to PNM for plotting).

So I would not expect this to be an intermittent problem, that's a compiled-in decision.

The solution would be to install the netpbm library and recompile the astrometry.net code (with a 'make clean' first).

cheers,

dustin

It seems to be input file dependent. The ones that work will work again, and the ones that do not won't work at all.

I am trying to install the netpbm now.

That's weird, in this one I don't see it printing

"Making source extraction overlay plot -- pnmfn = /tmp/tmp.ppm.dexQLg"

like in the first one... so it looks like it's not even trying to make plots.

When it fails to make plots, is that repeatable, or is it intermittent?

Kindly reply to the list.

cheers,

dustin

Oh, weird!  Would you be able to post an example file for each case (working / not working)?  Maybe I mis-remember when it uses netpbm.

thanks,

OK here are two jpgs

djs_2024_05_27_0000.jpg is a fail on my system (but not nova.astrometry.net

IMG_0468.JPG did solve on my w11 ubuntu system

Meanwhile I am still trying to get netpbm to install. No joy at this point.

Okay, two silly ideas to try:

- run "solve-field --verbose" the way normally do on those two images.  Let's compare the resulting logs.

- rename the IMG_0468.JPG one to IMG_0468.jpg (lower case "jpg").  There's one bit of code that tries to guess the format from the filename -- I didn't think it was used, but it has been a long long time since I wrote all this.

more complicated.  I did the verbose on both jpgs and then a diff on the logs and noticed that stuff was being called from two different paths, so I closed all of my xterm windows and brought up new ones and tried again, and both now failed, so I am not sure what is going on. I finally have netpbm installed without tiff and latex, so I wonder if I have to deinstall all of astrometry and reinstall again?

I must be getting senile and I think I need a little help. It turns out I had a previous version of astrometry installed on this laptop (I thought it was the previous laptop).

So in /usr/local/bin, I have version 0.89.  This version works on both jpegs.

In /usr/local/astrometry/bin/  I have vesrion 0.95.  This version fails on both jpegs, so I must have conflicts on the installation (that seems to be the most logical explanation).  What is the best way to fix this besides buying a new laptop because gear acquisition syndrome is always correct?

Hi,

The changes between 0.89 and 0.95 are mostly pretty minor, if I'm reading the notes correctly.  If the old one works, there's probably no pressing reason to upgrade.

cheers,
