Need help installing ffmpeg gem on Snow Leopard
Closed this issue · 2 comments
When I try installing the gem I get:
$ sudo gem install ffmpeg-ruby
Building native extensions. This could take a while...
ERROR: Error installing ffmpeg-ruby:

You need to install or tell me where to find ffmpeg. Check the mkmf.log file to see what erred out.
Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/ffmpeg-ruby-0.1.3 for inspection.
Results logged to /Library/Ruby/Gems/1.8/gems/ffmpeg-ruby-0.1.3/ext/ffmpeg_ruby/gem_make.out
$ which ffmpeg
/opt/local/bin/ffmpeg
When I check my path
$ echo $PATH
/opt/local/bin:/opt/local/sbin::/usr/local/mysql/bin:/opt/subversion/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin::/opt/local/bin
So what am I missing?
Thx!
Hi,
Did you see the Mac notes on the README? Basically it boils down to:
- Make sure you have installed the ffmpeg from macports
- Figure out if your Mac is capable of 64-bit, and whether your ruby is 64 or 32 bit, and set the ARCHFLAGS to match your architecture.
If you still can't do it after following the directions in the readme, please submit the contents of the /Library/Ruby/Gems/1.8/gems/ffmpeg-ruby-0.1.3/ext/ffmpeg_ruby/mkmf.log which will have the flags and command lines that were attempted in order to find the libraries.
You may also want to check drbrain's ffmpeg-rb, which is further along than this library (unless of course you are feeling like helping out) - his can already do a transcode.
Thanks!
Yes, I read through the README and have installed ffmpeg through macport:

I am not familiar with ARCHFLAGS and extconf.rb so was hoping to get a little help in that direction. Here is my mkmf.log
