Have the plugins been recompiled? I had a similar problem two days ago when using the latest Csound against an earlier build of
plugins on OSX.

Yes. I always do a complete clean and rebuild. However I changed compiler options from -march=nocona to -mtune=pentium4 and have not rebuilt all third party libraries. But this configuration ran on the previous build a week or so ago so I think it is a change in the source code.

Regards,
Mike

These are library file names (*.dll on Windows, not opcode names). Can you try making sure there are absolutely no plugins (or DLLs) in the
OPCODE6DIR64 path and run Csound. This does look like Csound trying to initialise incompatible opcode.

I just built on Windows and set my OPCODE6DIR64 to the location of
where I built.  I had one opcode library that was out of date and it
caused csound to crash on startup.  I deleted that and was able to run
Trapped in realtime.  I'm guessing you have an out-of-date opcode lib
that is incompatible and causing the crash.

(As a sidenote, I'm having problems building the java wrapper on
Windows; I think Oeyvind had mentioned something similiar recently.
It's an error with CsoundMIDIInputBuffer.  I have to move to other
things at the moment, but perhaps others have had this too?)

Hi Steven,

you will need to rename one of the symbols in that class, because it clashes with a Windows
API function or something.

The symbol that need to be changed is ‘SendMessage’, if you rename all instances of it in that class to
say, SendMidiMessage, it should fix it.

I modified to SendMidiMessage in interfaces/cs_glue.hpp and the .cpp
file too (committed to GIT).  That all now compiles fine on Windows.
It's an API breakage, but I don't know if anyone uses that stuff
anyways. How that's been in the codebase without it being changed
before I have no ideas, but hopefully should be fixed for everyone
now.
