Here's a Makefile that converts 3 GIFs to JPGs in a given directory:
1.jpg: 1.gif
/usr/local/bin/convert 1.gif 1.jpg
2.jpg: 2.gif
/usr/local/bin/convert 2.gif 2.jpg
3.jpg: 3.gif
/usr/local/bin/convert 3.gif 3.jpg
How do I generalize this to apply to ALL the GIFs in a given
directory? I tried:
*.jpg: *.gif
/usr/bin/local/bin/convert $1.gif $1.jpg
but this obviously doesn't work (I didn't really expect it to). Neither does
for $i (*.jpg) {
$i.jpg: $i.gif
/usr/bin/local/bin/convert $i.gif $i.jpg
}
(again, didn't really expect it to, since you can't put shell looping
into a Makefile).
