c - libtiff error: Old-style JPEG compression support is not configured -


while converting tiff bmp using libtiff on mac os x, got these errors:

scannerdata.tif: old-style jpeg compression support not configured.  scannerdata.tif: sorry, requested compression method not configured.

i using libtiff in mac os x.

my implementation of tiff bmp:

take @ source code of libtiff in "nmake.opt"

# # uncomment , edit following lines enable jpeg support. # #jpeg_support   = 1

...

!ifdef jpeg_support libs        = $(libs) $(jpeg_lib) extraflags  = -djpeg_support -dojpeg_support $(extraflags) !endif

so, default jpeg support not enabled.

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me

python - How to get a widget position inside it's layout in Kivy? -

i have gridlayout , added image widgets on after adding of images want draw rectangle in each image using canvas couldn't because don't know exact image widgets positions on gridlayout. code: http://paste.ofcode.org/3bdp9yhjrcrzmsztbu9hqp4 http://paste.ofcode.org/3az3gx4fxzr9dlhe2ami97c in last line of python code : rectangle(pos = (child.x - 2.4, child.y + 467), size = (70, 70)) how draw rectangle in child(my method not good^), also why gridlayout not coming in center after setting it's pos_hint = {"center_x" : .5}? if understand question right, try use such methods to_local() , to_parent() , to_widget() , to_window() . try substract position of gridlayout widgets' positions.
