Nov 29 2013.

Setting up Mac mini for gphoto2 using Dave Monet's notes:

libtool-2.4.2:

./configure --prefix=/home/dgm/linux

make

make install

libusb-1.0.9:

./configure --prefix=/home/dgm/linux

make

make install

libgphoto2-2.5.2:

setenv CPPFLAGS "-I/home/dgm/linux/include"

setenv LDFLAGS "-L/home/dgm/linux/lib"

setenv PKG_CONFIG_PATH /home/dgm/linux/lib/pkgconfig

./configure --prefix=/home/dgm/linux

make

make install

gphoto2-2.5.2:

./configure --prefix=/home/dgm/linux

make

make install

(does not need the CPPFLAGS and LDFLAGS of libgphoto)

------------

downloaded

libgphoto2-2.5.2

gphoto2-2.5.2

libusb-1.0.9

libtool-2.4.2

I am going to set this up like Dave Monet's configuration, in a directory

called linux off the user's home directory.

did sudo xterm

put the directories into /usr/local as root.

trying libtool: rats, no c compiler on the path!

so for that I need Xcode developer's toolkit

downloading that from Apple web site, 1.7 GB!

after some pain downloading and installing Xcode for this version of OSX,

trying again....

nope. It turns out I also need to install "Command Line Tools" for Xcode

ok, now we have gcc.

did same installation as Dave Monet has, except replace

/home/monet/linux

with

/Users/christopherstubbs/linux

seemed to work for libtool and libusb. Had to switch to tcsh for setenv to work.

got a make error for libgphoto2. Try putting pkgconfig on path with

set path = ( $path /Users/christopherstubbs/linux/lib/pkgconfig)

nope- try downloading and installing it

did

./configure --prefix=/Users/christopherstubbs/linux --with-internal-glib

now try libgphoto again

set path = ( $path /Users/christopherstubbs/linux/bin)

did setenv to this

set path = ( $path /Users/christopherstubbs/linux/bin)

got compiler errors for libgphoto2, fixed some undelcared variables in

linux.c but then encountered

libtool: link: gcc -o .libs/ptp2.so -bundle ptp2/.libs/ptp.o ptp2/.libs/library.o ptp2/.libs/usb.o ptp2/.libs/ptpip.o ptp2/.libs/config.o ptp2/.libs/olympus-wrap.o -L/Users/christopherstubbs/linux/lib ../libgphoto2/.libs/libgphoto2.dylib /usr/local/libgphoto2-2.5.2/libgphoto2_port/libgphoto2_port/.libs/libgphoto2_port.dylib -lm ../libgphoto2_port/libgphoto2_port/.libs/libgphoto2_port.dylib /Users/christopherstubbs/linux/lib/libltdl.dylib -lpthread -liconv -O2 -Wl,-dylib_file -Wl,/Users/christopherstubbs/linux/lib/libgphoto2_port.10.dylib:/usr/local/libgphoto2-2.5.2/libgphoto2_port/libgphoto2_port/.libs/libgphoto2_port.dylib -Wl,-exported_symbols_list,.libs/ptp2-symbols.expsym

Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64

make[3]: *** [ptp2.la] Error 1

make[2]: *** [all-recursive] Error 1

make[1]: *** [all-recursive] Error 1

make: *** [all] Error 2

[server:/usr/local/libgphoto2-2.5.2] root#

and gave up.

---------------

OK so let's try a totally different way- macports.

installed macports for Lion, 10.7

it puts the executable into /opt/local/bin so execute that explicitly,

did port -v selfupdate and that worked.

also did install of gphoto2 using ports and that worked as well,

although it stuffed things into /opt/local/bin, so need to add that to path.

This is a good resource:

http://photolifetoys.blogspot.com/2012/08/control-your-camera-with-gphoto2-via.html

Before running gphoto2 you need to terminate this "hijack" by running the following command:

killall PTPCamera

This will need to be done every time the camera is plugged in or turned on while connected to your mac.

/opt/local/bin/gphoto2 --summary

/opt/local/bin/gphoto2 --capture-image-and-download

works!!

to do next:

add /opt/local/bin to path

get JT's analysis stuff installed here.

Twilight times

Pachon is at West long of 70.7333, lat -30.2333

used USNO site http://aa.usno.navy.mil/data/docs/RS_OneYear.php to determine civil twilight times in UT.

Data file is here pachon_twilight.dat

broke that into one file per month, called mxx.dat with xx ranging from 01 to 12. Did

grep -v "%" pachon_twilight.dat | awk '{print $1,$3,$2}' > m01.dat

grep -v "%" pachon_twilight.dat | awk '{print $1,$5,$4}' > m02.dat

note that this intentionally reverses the times so that sundown in column 1 and sunrise in col 2, in UT

can use this to determine when to start taking data.

OSX cron jobs

set up time as GMT
sudo touch /etc/crontab
crontab -e edits the crontab file.
This is a good tutorial: http://rossb.biz/blog/2011/os-x-cron-jobs-a-simple-tutorial/
syntax we want is to start the task at a sensible time before sunset, say 2200 UT, i.e. 6 pm local. The script should then
1. check space avail.
2. create data directory
3. change image prefix
4. cd to data directory
5. compute appropriate number of images to take
6. wait for sunset time according to date
  1. then start collecting N images
  2. end when sunup or N is exceeded
  3. run simple analysis, convert to fits files, compress data, update status web page
  4. end

cron entry time format is

so we want

1 22 * * * /usr/local/bin/startnight.sh

I suppose we could just go ahead and use crontab to initiate each night's data collection at the desired time, within a range of dates. Say we break things up into two week intervals. For example we could do

1 22 1-15 01 * <tasks for first half of Jan>

30 22 16-31 01 * <tasks for second half of Jan>

etc.

So let's make the table of startup times, in the format crontab wants. Make a list of

minute hour dayrange month

15 00 01-15 01

10 00 16-31 01

05 00 01-15 02

45 23 16-28 02

to set shutter speed to one second: gphoto2 --set-config=/main/capturesettings/shutterspeed=1

(argument is simple shutter speed in seconds, it seems)

to take and store an image with existing settings gphoto2 --capture-image-and-download --filename ut113013.0001.cr2

Dec 1 2013

have fixed up cron task so that it works properly. It turns out need to set paths within the cron script, so sourcing bash_profile within script works.

did power cycle on mac mini and camera, and things run fine after power up.
