GPAC port

[bsleveritt@…]

Am I correct in thinking the GPAC library isn't available as a port yet? Fink has a version apparently, so I'm surprised it's not in ports yet, or is there an underlying reason we can't add it to MacPorts?

I'm particularly interested in MP4Box, which I'd like to rope in but haven't ever created a portfile, and I'm kinda confused as to why there isn't one already?

I suppose we don't have a port for it because nobody has ever suggested it to us before. ​Googling "GPAC MacPorts" yields some results, including ​a thread in 2008 where someone said they were making a Portfile. But it doesn't look like it was ever submitted to us.

I myself just became aware of GPAC and MP4Box a few days ago, and considered making a port for it, but have not yet begun. It looked like it has a bazillion dependencies, which overwhelmed me, and my specific need for the software soon expired.

I've installed it a few times lately, and it's fairly straight forward. The dependancies are listed in a ​recent news article from the source:

" To install all required packages, type: sudo port install zlib openssl libpng jpeg spidermonkey libsdl-devel ffmpeg faad2 libmad xvid libogg libvorbis libtheora a52dec openjpeg "

Since I'm not mad (and it's not actually present yet), I might give a portfile a shot. Course, I'll have to figure out how to do that. Time to study the guide.

gpac portfile

[ryandesign (Ryan Carsten Schmidt)]

tonytung, thank you for the Portfile, but it raises several issues.

• The Portfile claims this is version 0.4.6, but based on the fact that you're fetching from svn, and the revision you're fetching from doesn't mention anything about it being a final version of 0.4.6, and appears merely to be the latest revision at the time you wrote the Portfile, I believe it's only a development version leading up to 0.4.6. So the version field should be something else. Perhaps a datestamp.
• "nobody" is not a valid value for the maintainers line. You probably meant "nomaintainer".
• "master_sites" is not used when fetching from svn and is thus unnecessary.
• "use_configure yes" is the default and is thus unnecessary.
• You list a dependency on libsdl-devel. Would libsdl not suffice? You list a dependency on ffmpeg. Would ffmpeg-devel not suffice? Dependencies on ports that have -devel and non-devel versions should be written in path:-style not port:-style if either version will work. See #14540.

I got the list of dependencies from ​http://gpac.wp.institut-telecom.fr/2011/05/02/compiling-gpac-for-macos-x/

The rest should probably be fixed.

I have made the changes that Ryan suggested and switched to downloading from sourceforge. But I'm getting a weird permissions error. I assume I'm doing something wrong.
