Failure to compile 64 bit gtk on mac os

Attempted to install gtk+-2.17.2 on my mac. Had to install:
glib-2.21.2
which would not let me compile with multiple architectures, and
pkgconfig-0.9.0,
which won't configure because:

configure: configuring in glib-1.2.8
configure: running /bin/sh './configure' --prefix=/usr/local CC= CFLAGS= LDFLAGS= --cache-file=/dev/null --srcdir=.
configure: warning: CC=: invalid host type
configure: warning: CFLAGS=: invalid host type
configure: error: can only configure for one host and one target at a time
configure: error: /bin/sh './configure' failed for glib-1.2.8


which is bs because I don't have any compiler flags set.

So, gtk+ seems hopeless.

UPDATE: 0.9.0 is not the latest version, 0.23.0 is. Dumb version numbering.


GTK is absurd to install. You need:
pkg-config
glib
cairo
pixman
pango (MUST be installed AFTER cairo)
atk
libtiff
libjpg
jpeg2000 - but I just passed a flag to not do this because it didn't install right. --without-libjasper
fontconfig I mean, really? at this point it's just ridiculous....

and finally, it died with this:
checking Pango flags... configure: error:
*** Pango not found. Pango built with Cairo support is required
*** to build GTK+. See http://www.pango.org for Pango information.

which meant that I had to reinstall Pango because I had installed it before Cairo.

I believe this is where the term dependency hell comes from.

Also, I don't think any of these are x86-64 compatible.


Then I'm STILL not done.

PyGTK dies with an import error on dsextras, which a painful google search traces to pygobject. pygobject makes and installs fine.... but then I find out it installed to /usr/local/lib/python2.6/site-packages/gtk-2.0/, which is obviously not on my python path since I installed a framework.

So:
./configure --prefix=/Library/Frameworks/Python.framework/Versions/2.6/
in both pygobject and pygtk.

Oh, guess what? Need pycairo too. What happens there? What you'd guess:
ld warning: in /Developer/SDKs/MacOSX10.5.sdk/usr/local/lib/libcairo.dylib, file is not of required architecture

so when I configure pygtk:

The following modules will be built:

atk
pango

The following modules will NOT be built:

pangocairo
gtk
gtk.glade
gtk.unixprint

Damn. That blows.

python-64 -c "import gtk"
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/gtk-2.0/glib/_glib.so, 2): no suitable image found. Did find:
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/gtk-2.0/glib/_glib.so: mach-o, but wrong architecture

FAIL.

Installing 64 bit tcl/tk on Mac OS X

Everything is described in this post:
http://www.nabble.com/Error-compiling-tk-8.5.7-on-Mac-OS-X-10.5-td23790967.html


But here's a script too:

curl -O 'http://osdn.dl.sourceforge.net/sourceforge/tcl/t{cl,k}8.5.7-src.tar.gz'
for f in t*8.5.7*.gz; do tar zxf $f; done
cd tcl8.5.7/unix/
./configure --enable-framework --enable-64-bit
cd tk8.5.7/unix/
./configure --enable-framework --enable-64-bit
make -j 4 -C tcl8.5.7/unix
make -j 4 -C tk8.5.7/unix
sudo make install -C tcl8.5.7/unix
sudo make install -C tk8.5.7/unix


Concerns:
-might be necessary to do this in the macosx directory for some reason, though Aqua doesn't support 64 bits
-have to recompile python to get _tkinter to work (see a later post)

Make PDFs open with the thumbnails window open

Neat trick I picked up from here:
http://www.ghostscript.com/~ghostgum/pdftips.htm

Add this code:

\special{! /pdfmark
[/View [/XYZ null null 1] % unspecified x and y offset, 100% zoom
/Page 1
/PageMode /UseThumbs % /UseNone /UserOutlines /UseThumbs /FullScreen
/DOCVIEW pdfmark
}

to a LaTeX document (probably near the top) and when you ps2pdf it, it will open the PDF with the thumbnail bar open. This is very useful for proofreading after you latex a file. Of course, xdvi also works well for this, but xdvi is VERY unstable on the Mac. At least adobe, being a native Mac program, doesn't crash as often.

Comps 2 reflections

Comps 2 included some successes and some failures.

The most successful part of my Comps preparation was the Monday talk. The previous talk on Tuesday was somewhat helpful in terms of realizing that I needed larger figure axes, but otherwise provided no useful feedback. The Monday talk allowed me to realize what needed to be done to make my talk accessible to a larger audience.

At the defense, I ended up going only ~40 minutes despite having gone far over time in the Monday version and spending ~5 minutes answering questions from Don and Mike. I think that was a good thing; I didn't need to say anything more even though there was an enormous amount of additional material I could have covered.

The main change I made from Monday to Friday was reorganizing such that I discussed the largest scales first and zoomed in, and I spent much more time discussing the larger context of my work. Unfortunately, I also spent most of the week before the presentation determining the larger context and reading papers. Ideally, I would have done that before handing in the paper.

The closed door Q&A section went OK but not great. There were a few important bits of information related to the IMF that I didn't know off the top of my head - e.g. the ratio of total # of stars to the # of B stars. I got the lowest mass star (.07) confused with the most common star mass (.3). I wasn't particularly able to integrated the IMF on the board either. I didn't remember the Jeans mass-temperature and mass-density relationships but was able to derive them quickly enough.

Probably the biggest problem was dealing with a question about the partition function - specifically how did the partition function come into play in the column density equation. I didn't come up with the right answer at all, and in particular quoted the wrong distribution. However, I think a big part of what they expected to hear was a dependence on temperature AND degeneracy, and I never explicitly mentioned degeneracy. It turned out that the equation I had quoted in both the paper and the talk was correct, but I couldn't come anywhere close to proving that on the spot.

My expected result is therefore a low pass, though it was not made explicit. That's rather unfortunate as it's possible that another month of preparation could have gotten me the high pass, but at the same time, it's well worth having the project done.

Most important astronomical publications

I'm interested to hear input on this. Some I know of:
Cardelli, Clayton, Mathis 1989 - determined interstellar extinction law
Kurucz 1993 - possibly a book? Stellar atmosphere calculations

public perception of astronomers

Public Perception of Astronomers

While the article has some.... almost-interesting points, I don't agree with the thesis or the suggested methods. I don't really have a problem with the stereotype of astronomers being the old, white, socially inept guy - because for the most part that's a fair assessment. We're scientists, and at least for me and my peers, that's directly correlated with not fitting in to some social circles.

I agree that we should become better communicators in general, but it's silly to think that embracing new technologies (i.e. social networking tools) is going to change the public image of astronomers at all. Personally I hope to see a backlash against social networking and blogs sometime in the next 5 years, but who knows.... after all, I'm writing a blog post.

Comedic timing has been fixed using quicksilver's command line execution abilities.

Also been playing with dashboard... Safari's new dashboard feature is pretty cool, but also incompetent.  It refreshes every time you reload the dashboard, which is inefficient and makes saving settings impossible.  Also, the gmail compose feature fails miserably.  So, dashboard must die again.

Quicksilver and Awesome

Set up f17-19 today to play amusing sounds. Also, recalled that I use ScreenSaverEngine to lock my screen with a shortcut key.

Quicksilver triggers are the way to do it. Mac is stupid w/o quicksilver.

Python 64 bit!

I got python 64 bit to compile, but it required a number of tricky steps.

First, this guy has the instructions I followed:
captnswing

However, it didn't work entirely as advertised. I ran the configure as advertised:

./configure --enable-framework=/Library/Frameworks \
--enable-universalsdk=/ \
MACOSX_DEPLOYMENT_TARGET=10.5 \
--with-universal-archs=all \
--with-readline-dir=/usr/local


then the make install, but /usr/local/bin/python pointed to the wrong place, so I replaced the symbolic link in my python path with the correct one:

sudo rm /Library/Frameworks/Python.framework/Versions/2.6/bin/python
sudo ln -s /Library/Frameworks/Python.framework/Versions/2.6/bin/python-64 /Library/Frameworks/Python.framework/Versions/2.6/bin/python


Now python is 64 bit:

eta ~$ python -c "import sys; print sys.maxint"
9223372036854775807


I haven't checked whether it works yet though...

Update: Had to reinstall with gnu readline installed. Also have to install PyQt4 and might have to recompile numpy...

numpy won't compile with python 2.6.2:

That sucks.

Hosting on my mac

I'm hosting my website off my mac; it should be accessible to the outside world now: eta.colorado.edu.

A few things went into this....

  1. Don't install the fink version. The two versions clash and depending on how you access your computer you could end up looking at entirely different directories (e.g. localhost and eta.colorado.edu referred to different sites for a while)
  2. The configuration file is /private/etc/apache2/httpd.conf
  3. I needed to change DirectoryIndex to index.htm (from index.html)
  4. uncommmented "LoadModule php5_module libexec/apache2/libphp5.so"
  5. had to allow override so that .htaccess files would work.

Mac stuff cont'd

Trying to get Apache server to run, and it's just a pain.

I frequently forget how to update the locate database because it's different on macs. Marcos' Mac Singularity has the instructions .

In short:
sudo /usr/libexec/locate.updatedb

Google has failed me

So, either no one on the internet has successfully installed 64-bit python on a mac (which I find nothing short of impossible) or google has totally failed. None of the hits for any combination of 64 bit, python, mac, etc. has shown a useful result. Wow.

Caffeine

Caffeine consumption stopped around mid-October. I think it was when I got back from observing so October 20 give or take. Re-started consumption mid-March. Date is hard to say... I think it was Sunday before Spring Break, but hard to say because I still took it easy until ~last week.

Conclusions? I'm probably more tired in the mornings with caffeine than without. Also, probably perform better @ ulty when I'm not addicted. However.... not really conclusive. Just addictive.

weekend

What did I do this weekend?
-upgraded PyRAF from 1.6.1 to 1.7
-switched matplotlib backends from TkAgg to Qt4
-put up a new article on molecularclouds


So... totally unproductive, but only in an awesome way?

I tried to switch PyRAF from X11 to Aqua a la Ticket 86 on the PyRAF trac site, but it failed with a can't-load error.

Also, updated readcol documentation so that it makes sense. Sam has used it, Robbie might.
