confused over ffmpeg-ffserver-dev.tcz

[3rail]

I'm trying to compile motion the web cam application on tc 3.6.0 (http://www.lavrsen.dk/foswiki/bin/view/Motion/WebHome). I'm getting an error during configure:

Code: [Select]

avformat.h not found
I've loaded (both on boot and on demand) ffmpeg-ffserver-dev.tcz which is supposed to satisfy this dependency but configure can't find it. I'm trying to figure out where ffmpeg-ffserver-dev.tcz gets mounted? Or how to unpack ffmpeg-ffserver-dev.tcz to look inside it?

Code: [Select]

sudo mount
does not show a loopback device where ffmpeg-ffserver-dev.tcz is mounted

Code: [Select]

sudo su
find / -name avformat.h
finds no files named avformat.h

I'll admit I'm pretty confused at this point. TIA.

look in /tmp/tcloop/ffmpeg-ffserver-dev to see what's inside the extension

You can also loop mount the extension, eg:

Code: [Select]

$ sudo mount -o loop ffmpeg-ffserver-dev.tcz /tmp/image
..or use a squashfs command to list the contents, the exact command escapes me at the moment - "unsquashfs -l" maybe?

I never got ffmpeg-ffserver-dev.tcz to load properly but using your loop mount command I was able to copy the dev files to the right place and continue with the build so thanks for that.

For future reference, motion requires bash to compile properly, ash won't do for configure
