pyexiv2

mac osx 10.6 build problem

Asked by reco

we are trying to build pyexiv2 for mac osx 10.6.4

installed packages via mac ports

scons @2.0.1_0
python26 @2.6.6_0+no_tkinter
exiv2 @0.19_0
boost @1.44.0_0+python26
pyexiv2 form source pyexiv2 0.2.2

following robin mills tips @ http://clanmills.com/articles/gpsexiftags/macos.shtml we made the following changes to the SConscript

I'll build the combo:

scons @2.0.1_0
python26 @2.6.6_0+no_tkinter
exiv2 @0.19_0
boost @1.44.0_0+python26
pyexiv2 form source pyexiv2 0.2.2

I do have a suggestion. On each library you have built and installed run (libpyexiv2, libexiv2.dylib, libboost-python and python himself)

"otool -L"
"lipo -info"
"install_name_tool"

Another thought is to set the environment variable DYLD_PRINT_LIBRARIES (see man dyld) and start up again to be sure your python is loading your libraries.

I don't think this is going to reveal anything extraordinary. I think this is about the same as the doctor using his stethoscope - it keeps you busy while he's thinking!

Thanks Robin for looking into this!
I'm away from home at the moment and haven't had time to test the mac build yet, but I'll keep a close eye on the resolution of this question.
Note: Robin, you may want to add comments to the question, instead of modifying the original description.

hi olivier,

this would be amazing. we are now using the command line tool of exif2 inside python.
we are pretty new to to this stuff. but would love to help to get this running.

Yes. I assigned the issue to me, the web-ui immediately offered to
change the description - with no option to "Add new information". So I
tacked it on the bottom (with a very clear indication of what I had done).

However after I submitted the update, it offered to "Add Note", which
was what I expected in the first place. Software .... grrrrrrrrr ......

Anyway, I'll spend Saturday morning on this.

Good News. I have a fix.

This issue is being caused by build/libexiv2python.dylib being built to link again /System/Library/Frameworks/Python.framework instead of /opt/local/Library/Frameworks/Python.framework/Versions/2.6/Python built by macports.

The fix is to use install_name_tool to change the linking:

A much better fix is to change src/SConscript to link to the Python framework built by macports in /opt/local/Library/Frameworks. I've been unable to achieve that (however I'm sure I'll figure this out and update this page). My unsuccessful attempt was to add a -F/opt/local/Library/Frameworks link option, however that isn't sufficient to fix this.

if sys.platform[:6] == 'darwin':
    print 'sys.platform' + sys.platform[:6]

For the moment, the magic is to build as follows:

$ cd pyexiv2-0.2.2
$ scons
$ install_name_tool -change /System/Library/Frameworks/Python.framework/Versions/2.6/Python /opt/local/Library/Frameworks/Python.framework/Versions/2.6/Python build/libexiv2python.dylib
$ sudo scons install
$ python2.6
>>> import pyexiv2
>>> help(pyexiv2)
---------- Happiness ----------

Here is the src/SConcript file which I used (courtesy of reco). I have included the unsuccessful 'fix' to LINKFLAGS (on line 44). You will have to run install_name_tool between scons and sudo scons install to reach your goal.
