So, someone on facebook said he couldn't load the externals. The usual
~load _object: Symbol "else_setup" not found~ is given. He also said he had
to run *sudo spctl --master-disable* to allow it to load, no idea what that
means, but doesn't look good as well.

The fat binaries run fine in my mac intel...

Let me tell you my process.

Hi, I now have a machine with Monterey and XCode 13 installed and I want to
build fat binaries for my externals. I still have a mac intell by the way.

Before, I was using the above command to build fat binaries with
pdlibbuilder for both 32/64 bits (taken from some other email to this
list). Today I installed Monterey and XCode 13 on a mac intel and tried
that command but got an error.

I understood it tried to compile for 32/64 bits  t even possible to create
a single fat binary for all the 3 architectures? It complained that *The
i386 architecture is deprecated for macOS*, so I guess I can't build it
anymore for it with XCode 13, right? I wondered if I could build a fat
binary for 32/64 bits and arm, but I can forget about it, right?

Well, I then tried compiling with pdlibbuilder like this:
"make install objectsdir=../ arch="arm64 x86_64 i386"  extension=d_fat"
didn't work...

It didn't work either... then I tried.


*make install objectsdir=../ arch="arm64 x86_64"  extension=d_fat*

and it worked, it did build, but I got stuff like

++++ info: linking objects in timed.gate~.d_fat for lib else
cc -undefined suppress -flat_namespace -bundle  -arch arm64 -arch x86_64
-mmacosx-version-min=10.6  -o timed.gate~.d_fat
Classes/Source/timed.gate~.o  -lc
*ld: warning: ignoring file Classes/Source/timed.gate~.o, building for
macOS-arm64 but attempting to link with file built for unknown-x86_64*
++++ info: linking objects in trig.delay2~.d_fat for lib else

I was worried from the warning *attempting to link with file built for
unknown-x86_64* would mean it would work for apple silicon but probably not
for mac intel, but it worked for mac intel, so I thought it'd work just
fine for apple silicon as well, but it didn't!

I couldn't upload to deken because the server is down, but I made deken
package the external, it did create a deken file named
*else[v1.0-0rc1-test_with_live_electronics_tutorial]*
*(Darwin-amd64-32)(Darwin-arm64-0)**.dek*, so that seems ok. Nonetheless, I
got some warnings in deken, probably for all objects, which said, for
example:

OUCH: couldn't detect float-size for 'else/asr~.d_fat'

      and no default set, assuming None

      use '--default-floatsize <N>' to override)



 I didn't bother trying to explicitly define a float size because I wasn't
uploading it to deken... and this wouldn't change my build anyway...


So, I'm really lost here and I don't know what I should do to build a
proper fat binary...


As for not being able to create a fat binary that also includes *i386*, I
guess we can forget about it, for deken at least. I can still build for it
and keep that on my release page on github if needed, but it doesn't seem
like something I should bother that much these days (I'm not even
mentioning ppc).


Anyway, any hints on what I can do to build it properly? And also maybe
avoid the needed *sudo spctl --master-disable *command (whatever that is)?


Thanks
