Re: Compile libmp3lame for x86 on arm?

I *think* that can be fixed by just removing lame_init_old line from includ=
e/libmp3lame.sym :

after ./configure; make, I got this:

Undefined symbols for architecture arm64:
  "_lame_init_old", referenced from:

Hi Dave,

I think the generated DYLIB was in lame-3.100/libmp3lame/.libs/libmp3lame.0=
.dylib (note the hidden ".libs" folder), if that helps. Hopefully someone e=
lse on the list can chime in about specifying intel or fat, etc.

Thanks,
Kris

thanks, I did do that normal thing (./configure; make) but it didn=92t crea=
te a dylib (AFAIK)

And specifically I don=92t know how to specify it should be intel or fat?

Hi Dave,

I am not a LAME developer, so probably not super helpful... But there are s=
ome building instructions in this INSTALL file (https://sourceforge.net/p/l=
ame/svn/HEAD/tree/trunk/lame/INSTALL<https://sourceforge.net/p/lame/svn/HEA=
D/tree/trunk/lame/INSTALL> ), which is also distributed with the source cod=
e. I think I was able to generate a DYLIB for an Intel Mac at some point by=
 running:

% ./configure
% make

as suggested. Not idea about ARM, etc. though.

Hope this helps somewhat!

Kris

I=92ve downloaded the sources but do not know how to configure it to build =
for x86 (or fat) when compiling on an arm machine.

Also, and more fundamentally, I can=92t figure out (no instructions) how to=
 compile libmp3lame.dylib

Any =93how to=94 articles anywhere?
