[MacRuby-devel] Request for feedback on new tutorial

[Emil Tin]

nice tutorials!

i tried following the tutorial but ran into a few problems:

1.
wget command was not found. wget is not installed by default in os x, it seems.

2.
linking agains foundation and libz: as an xcode beginner, i had to guess a bit to figure out how to do this. i suppose you mean adding items in the 'linked libraries' area of the taglibbundle target info pane. maybe describe in a sentence the simple steps involved.

3.
can't compile. when i try to build the project, i get a lot of errors. here's the first:

i'm using taglib 1.6.3, os x 10.6.4 and xcode 3.2.3

I'm not very experienced with xcode, and not sure what to do next. i followed the steps you described wtih setting up xcode build settings, etc. it seems the header files is somehow not included correctly?

thanks,
emil
