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

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
...
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
- check space avail.
- create data directory
- change image prefix
- cd to data directory
- compute appropriate number of images to take
- wait for sunset time according to date
- then start collecting N images
- end when sunup or N is exceeded
- run simple analysis, convert to fits files, compress data, update status web page
- end
cron entry time format is
<minute> <hour> <month-day> <month> <week-day> <command to execute>
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
