Hi again,
I've tried a the Sane interface from PIL and I get the following
error, when I run the demo_pil.py from the Sane directory.
------------------------------------------------------------
SANE version: (16777231, 1, 0, 15)
Available devices= [('v4l:/dev/video0', 'Noname', 'Logitech QuickCam
Pro 3000', 'virtual device')]
Traceback (most recent call last):
File "/PyWebcam/demo_pil.py", line 17, in ?
s.br_x=320. ; s.br_y=240.
File "/usr/lib/python2.4/site-packages/sane.py", line 150, in
__setattr__
raise AttributeError, 'Inactive option: '+key
AttributeError: Inactive option: br_x
------------------------------------------------------------
Next, I looked at v4l support for python with absolutely no
documentation. I tried to build the modules and I get the following
error:
------------------------------------------------------------
python setup.py build

v4l.c:1585: error: for each function it appears in.)
error: command 'gcc' failed with exit status 1
------------------------------------------------------------
I also looked at libfg http://antonym.org/libfg and I get the following
errors again:
-------------------------------
python setup.py build
running build
running build_ext
building 'fg' extension
gcc -pthread -shared build/temp.linux-i686-2.4/fgmodule.o -L. -lfg -o
build/lib.linux-i686-2.4/fg.so
/usr/bin/ld: cannot find -lfg
collect2: ld returned 1 exit status
error: command 'gcc' failed with exit status 1
I google-ed extensively have so far found only these three packages.
Any ideas why I get these error messages?
