Calling steve method from C++ code
Hi, is there any (easy) way to call a steve object method inside a C++ code?
I mean, something like:
int execute_method(brEval args[], brEval *target, void *i) {
brInstance *i = BRINSTANCE(&args[0]);
i->call_method("my_steve_method");
return EC_OK;
}(I think you get the idea =)
TIA.
brMethodCallByName and brMethodCallByNameWithArgs
Check out the functions brMethodCallByName and brMethodCallByNameWithArgs. I'm not certain they're properly exported for Windows plugins under 2.4, but they should be for the 2.5 betas (http://www.spiderland.org/breve_2.5b).

Example?
In the svn slBrevePluginAPI.h it's not exported AFAICS. There is only brMethodCallByNameWithArgs and it's commented. In the 2.5b it's exported in slBrevePluginAPI.h? Should I include any other header?
Do you have any simple (working) example of what I want to do?
Thanks for the help.
import site failed on breve 2.5b
I' ve installed breve 2.5b and get a python error saying it can't import the site package when executing breve :S
I need some clarification
I need some clarification here. What platform are you on, and did you install from source or from the latest builds? Was the error when you were trying to launch breve, or when you tried to run a simulation?

Clarification
I'm using breve CLI precompiled for windows. I'm running a simulation. I've done:
1) Uncompress breve in a directory
2) cd plugins\samples
3) make (using MinGW 5)
4) cd ..\..
5) bin\breve.exe plugins\samples\c++SampleDemo.tz
6) I get this error:
C:\Documents and Settings\luca\My Documents\Celdas\breve_2.5b1>bin\breve.exe "pl ugins\samples\c++SampleDemo.tz" 'import site' failed; use -v for traceback Traceback (most recent call last): File "", line 1, in ?

I can strongly recommend using Bloodshed IDE for Breve plugin development. It automatically uses Cygwin's gcc compiler and does not need any further configuration (linking etc) for creating dlls (which can be really a pain).
temporary problems in the source
Ah, sorry, it looks like this was the result of some temporary problems in the source, which has since been fixed. I will make a new build of CLI for Windows soon to get this fixed. In the meantime, the fixed source is in SVN.
