how to compile external to be visible on all machines?

Feb 18 2006 | 1:32 pm


few people reported problems with my externals which i compiled under
they are not visible as max externals but as folders or something else
(and they obviously don`t work in max)

while i have no problem on my machine (os x.3.9 with latest max/jit).

as far as i can say there is no general situation (system or max


where the problem occurs,

are they any tips for compilation and compatibility.

(or is it a problem on the local computer?)

i saw the other posts about it, although related, i couldn`t solve it,

Hi Wojciech,
this has also been a problem bugging me for some time.
Do you have a Pkginfo file inside the Contents folder of your .mxo
Please find one attached that should make your externals appear on any
Within your xcode project you can easily create it by checking "Force
package info generation" in your target’s build option and in the
"Properties" register card enter Type:iLaX and Creator:????

hope that helps,

I’m also wondering if this is related to the "/7" problem discussed on
the main Max/MSP list. As in: type /7 into an object box (as if you
were creating a divide-by-seven object but leave out the blank). Hit
enter. On some OS X configurations, an arbitrary external is
instantiated under the /7 name. I think in all cases it has been XCode
bundles that are bitten.

Presumably these problems will be resolved when 4.5.7 is released, but
who knows?

This is because of the lack of the MaxAPI and MaxAudioAPI frameworks
on the target system. The Max runtime uses them as a springboard to
load mach-o bundles from a CFM application. I have no insight into
the Cycling process, but I would imagine this requirement will go
away when Max becomes a mach-o to achieve universal binary status.

Try tossing those two frameworks onto the other system and see if the
problem still occurs. I have had to ask people to install the demo
of Max/MSP to get my mach-o extern’s to work (YUCK!).
