Hi,
I try use precompiled byte-code. I successfully compile my script then successfully loaded it but I has encountered with serious trouble - i got erorr id trying obtain fucntion id by calling GetGlobalVarIndexByName or GetFunctionIdByDecl. Also functions GetFunctionCount() and GetGlobalVarCount return 0.
Why i done wrong? Maybe there are special condition need when generated byte code?
Best reards,
Eugene.
Using precompiled byte-code

Did LoadBytecode() return an error?
Did you receive any messages on the message callback?
Can you show how you did it? There is nothing special that needs to be done. Just follow the instructions in the manual.

Thanks for reply 
so I just call mod->SaveByteCode(&stream); after i compile script.
Before load byte-code I call machine->SetEngineProperty(asEP_INIT_GLOBAL_VARS_AFTER_BUILD, 0) and then call mod->LoadByteCode(&straem);
LoadByteCode do not return error.

The message callback can give useful hints on errors that occur. However, as you say the LoadByteCode() doesn't return any error, then the message stream would have any information either.
From what you're saying you're not doing anything wrong. The bytecode should be loaded properly and the functions and global variables should be available after the load.
Can you debug into the LoadByteCode() too see what is happening? It looks like you're loading an empty script.

i add log function to BinaryStream to see if anything happens and yes scriptmodule loading bytecode by small chunks
there is code snapshot:
void ScriptModule::BytecodeStreamLoader::Read(void *ptr, asUINT size)
{
memcpy(ptr, buffer, size);
buffer += size;
//core.Trace("Read bc %i", size);
}
ok, i will try debug [color=#282828][font=helvetica, arial, verdana, tahoma, sans-serif]

Hi!
After debuging angelscript i found my stupid mistake i call build after loading bytecode thats leads to reset script module.
Also i found another my mistake i call [color=#282828][font=helvetica, arial, verdana, tahoma, sans-serif]

Great. That would definitely explain the empty module.
The call to SetEngineProperty(asEP_INIT_GLOBAL_VARS_AFTER_BUILD, 0) turns off the automatic initialization of the global variables. To manually initialize the variables after the build the method ResetGlobalVars() on the module must be called.
Normally this is not necessary, but there may be valid situations when the global variables shouldn't be initialized automatically. One is if you're building an offline compiler, i.e. an app that just compiles the scripts but don't execute them, another is if you want to add additional verifications on the build before initializing the variables.

Andreas
