Greetings.
1. The version
$ guile --version
guile (GNU Guile) 3.0.9
2. The machine
$ uname -a
Linux bioscope 6.3.7-arch1-1 #1 SMP PREEMPT_DYNAMIC Sat, 10 Jun 2023 00:35:35 +0000 x86_64 GNU/Linux
3. The package
$ pacman -Qi guile
Version : 3.0.9-1
Architecture : x86_64
Depends On : gmp ncurses libunistring gc libffi libxcrypt
4. The problem
I'm
working on application for scientific computer vision. We use one of
the Andor camera. I've decided to code configuration and user interface
parts in Guile Scheme, as to my experience, it is a lot simpler. But
i've encountered strange error.
Attached
archive contains three source files. cam.c implements simple sequence of
interactions with camera driver. That sequence should result in image
acquisition and in the clicking of camera shutter. I've built shared
library from this code (see makefile, please) and have linked it with
simple main program (test.c). When i run resulting binary, i get
$ ./test
INITIALIZATION
CONFIGURATION
ACQUISITION
-- shutter clicks here
AWAITING
SHUTTING DOWN
When i try to run this code from Guile Scheme, as extension, it hangs.
$ guile test.scm
defining single-shot
INITIALIZATION
CONFIGURATION
ACQUISITION
AWAITING
-- no shutter clicking
^C
I
do not understand how to debug further, so i just include straces of
both runs in attached archive. If anyone will give me some directions
for investigation of the problem, i'll try to do my best. Thanks in
advance!
- Respectfully, Mike.
