Thank you for the information regarding this. I went ahead and used the framework that you recommended and it is working very nicely.

We recommend this framework to our Sound Studio customers, and it's performed very well. Totally recommended to anyone who wants UB MP3 encoding in an app they're building.

I found a universal build of LAME on the net that works great. It's a framework bundle, so when locating the library you have to delve into the bundle and choose the executable data file. At least that's the way it is in Audacity.

If you don't actually want to modify it, you might try searching the net first. I don't remember where I found it or I would post a link to the site.

I did check the archives and this has been asked before, but I'd like to ask for a clarification as I didn't completely understand the issue after reading the archives.

I'm trying to compile LAME as a universal library.

Apparently it is set to use several -M switches: MT MD MP MF which gcc tells me are incompatible with using -arch.

What do these switches do exactly that makes them not work with -arch?

Automake/autoconf add these flags unless you pass --disable- dependency-tracking to configure. You will need to be very careful! http://lame.cvs.sourceforge.net/lame/lame/configure.in? view=markup shows that lame's configure checks for sizeof() all the standard types and endianness. It also enables bits and pieces based on host_cpu. This is not a simple add some -arch flags and go type build to get it universal.
