Exiv2

Hi Bob,

What about something like this:

$ cd exiv2-0.18.2
$ ./configure --disable-shared
$ make

to build a standalone static binary src/exiv2.

(Add $ strip src/exiv2 to discard symbols from the file and make it slightly smaller.)

That looks like it may be the perfect solution, will just figure out how to stop windows clearing the executable bit when I wrap it into my extension xpi and it may just work.

Thanks soooo much :) Beats the proverbial c**p out of my previous solution of shipping with a Macport-ed .pkg and hoping I could manage the install :)

Cheers Andreas, another of your always-fantastic responses gratefully recieved :)

As always, Andreas is 100% correct in his solution and this will build a static version of exiv2.

If you want to distribute this to all Mac users, you may wish to build a "Universal" binary which includes the code for both Intel and PPC macs. I have been able to do this by building the i386 version on my iMac and the PPC version on my (elderly) PowerBook Pro - and then combining them together with lipo. If you want this (and can't build it for yourself), I'd be happy to build it and send you the binary. Let me know.

Finally got it all up and running :) Thanks for the help :)
Cheating a little to stop windows wiping my permission-bits by zipping it, then unzipping within the extension the first time a user requires it :)

Robin I saw your excellent article about compiling a Universal Binary, but I must confess ~90% of it went way over my head. (I was until recently a C# developer lol :)
I'd give it a go but without a ppc system to build on I think I'd be totally stumped.
If you have a universal binary available I'd love to run it, but if not no worries :)

Thanks
Bob

Here's the build:
http://clanmills.com/files/exiv2-0.18.2-MacUniversalStatic.zip

I created the archive with the 'zip' command which I believe preserves the x-bit.

The difficulty in building a universal exiv2 on a Mac is cross compiling. The build seems to be determined to produce a native build. So on the PPC it builds for PPC and on Intel for i386. So you really need a PPC to build the PPC version. I don't think this is an exiv2 issue - I think it's in the dependent libraries. Apple provide a Tech Note about creating universal builds: http://developer.apple.com/technotes/tn2005/tn2137.html

Once things are built, combining them together is easy with lipo:
lipo -arch ppc path/to/ppc/exiv2 -arch i386 path/to/i386/exiv2 -create -output path/to/universal/exiv2

I built the ppc version on Tiger (10.4) using the following commands:
./configure --disable-shared MACOSX_DEPLOYMENT_TARGET=10.4
make MACOSX_DEPLOYMENT_TARGET=10.4

I have much longer and more detailed build notes for building exiv2 and pyexiv2 at:

The latest Mac/Universal (and Windows) build of pyexiv2 for Python 2.6 can be download from:

Tester's welcome!

Heya Robin.

That's phenomenal :) Thanks so much for taking the time to build it :) Hugely appreciated :)

Bob
