Segmentation fault
prahjister commented 6 years ago

Hey John....i was wondering if you had an idea what this issues is?

jhdewitt commented 6 years ago

Hello; apologies for extended afk.

Early on in the project, I was using jpg from canon cameras for input and needed to read exif data to facilitate proper parameters for reconstruction. I used an external program called exiftool and parsed the output. However, the exif related code is deprecated and only known to work on osx. I'll clean that up in next commit.

Will investigate segfault on arm box and provide update. Thank you for log!

prahjister commented 6 years ago

Hey

I just went through and tested on a raspberry pi with the same results.

sventiede commented 5 years ago

Commenting out all references to Exif also solved the seg fault. See attached for a copy of slcrunch.ccp that appears to work (I still dont know how to make all of this work but it does the thing!) Don't forget to recompile the slcrunch program after replacing slcrunch.cpp (make slcrunch) slcrunch.zip

I got the same problem on a Ubuntu PC, I confirmed it is now working...with the sventiede file... thank you
