[squeak-dev] loading one mcz depending on another

Hi,

I need to load 2 mcz. The first need to be initialized before I load the second.
I did a Package-all but it doesn't work (syntax error). The load order
is ok, but I guess the initialization is done at the end... hence my
problem

Is it possible to use MCM for that ? I just can't use it....

Thanks

Cédrick

I don't see how a syntax error could be related to MC. Have you tried
to load Package-1 alone then Package-2?

If you want MCM, install MC1.5.

Yes that way it works.

It for Prolog. In some packages they are examples in Prolog syntax
which need to use a different compiler. If I load all the packages,
I've got a syntax error as it doesn't know how to compile the "prolog"
methods. If I load first the compiler then packages with prolog
syntax, then it's ok.

You might want to try with MC15, even without MCM. If you still have
the problem, send a mail to Keith and Matthew.

No, I think you have to use Universe.

IMHO that's a problem we haven't found a solution for in MC, yet.

Sometimes (as in cdrick's case) you must load two packages
independently, because the first needs to be initialized before the
second can load.

Sometimes, packages need to be loaded together, for example, when a
class or method is moved from one package to the other.

Maybe packages that need to be loaded separately need to be marked?

I thought that MCM was loading package one after the other. (in fact
this is for that reason we could not
use MCM for Squeak 3.9).

Now in scriptloader we can chose to load one after the other or
together.

Re: [squeak-dev] loading one mcz depending on another

Installer now supports loading packages together using the following idiom.

Installer squeaksource project: 'SomeProject';
addPackage: 'PackageA';
addPackage: 'PackageB';
install.

best regards

Keith

p.s. with atomic loading enabled both should be atomically switched in
together

IMHO loading one package after the other should be the default so that
you can rely on classes in packages you depend on to be initialized.

And IIRC at your request I added the option to load packages together.

Different versions of MCM default to different strategies though.

As far as I understand the problem is not the load-, but the
initialization-order.
