[9fans] dyncall on Plan9

[9fans] dyncall on Plan9

[Tassilo Philipp]

Hi,

I finished my dyncall/Plan9/x86 port - thanks again Cinap and Steve for
pointing me into the right directions about the Plan9 calling convention,
a few weeks ago.

Anyways, dyncall has Plan9 support for x86, starting with Version 0.6,
maybe someone likes it or finds it useful (www.dyncall.org).

Cheers,
Tassilo

Hi,

thanks for the feedback. You are right about the error... However, at the
moment, I don't have callback support on Plan9, so this is an ugly detail
that I try to build it unsuccessfully, but it doesn't block you from using
dyncall which seems to build fine on your machine.

I'm sorry for this inconvenience, please change a line in dyncall/mkfile
from:

DIRS  = dyncall dyncallback dynload

to:

DIRS  = dyncall

to get rid of this error (and yes, there is no dynload support, either, at
the time of writing). I hope to get dyncallback support in for 0.7...
well, I shouldn't have forgotten to change the line mentioned above... oh
well ;)

You can svn checkout the latest version, which includes the fix.

Thanks,
Tassilo

Well, there is numerous reasons ranging from very simple (ever tried to
wrap a vararg func?), to complex (dynamic message systems, virtual
machines, script language implementations/bindings, interpreters, etc.).

The library can be useful without having support for dynamically linked
libraries on the target platform - I guess we don't even have to argue
about the fact, that "dynamic libraries" aren't the best thing the world
has seen...
The point of dyncall is not "load a dll/so and call a function", but to
allow you to do something you simply can't in C.

For me, the Plan9 port was mainly instructional, and who knows, maybe
someone finds it useful...
