(solved) GetInterface() fails for (68k) ID3tag.library, any ideas?

I've converted ID3tag.library's 68k headers to OS4 (following same steps that have worked for many other 68k libraries), but find that after OpenLibrary() succeeds, GetInterface() fails.

It could be that I've mucked-up the C headers in their conversion from OS3 to OS4 (although I don't know how), OR maybe I'm doing something else wrong...

Anyone have any suggestions? OR even better, have C includes & test program for ID3tag that compiles & works on OS4?

(Is it possible a recent OS4 SDK broke conversion of 68k headers?)

@ChrisH
You mention updating the headers but did you create an external OS4 interface file for the 68k ID3tag.library (e.g. ID3tag.l.main) and place the interface file in LIBS: with ID3tag.library?

@ChrisH

If you don't want to create it yourself, you can use the id3tag.l.main from this archive: http://aminet.net/package/mus/play/DAPlayer_os4

However, here are instructions how to do it yourself: http://thomas-rapp.homepage.t-online.de/ppclib.html

@thomas
Thanks! Your id3tag.l.main fixed my problem, so I am puzzled why mine does not work. I effectively followed these instructions:

(And my .l.main file is 1.3MB vs your 8KB !)

@ChrisH

Here is the source code of my version: http://thomas-rapp.homepage.t-online.de/download/id3tag_os4.lha

Maybe you find something by comparing with yours.

@thomas
Thanks. I've now successfully got a working .l.main file using the files I generated. Turns out the script I had written was compiling the wrong file! Not sure how long (or even if) I'd have spotted that, without your example for comparison. The id3tag.c file also had some errors, so having your file for comparison speeded-up fixing them.
