Hi all, I need some help to embed Csound in a Windows application -
that is in a way so that the computer on which the application is
installed does not need to have Csound already installed.

I have embedded Csound64.dll in my application, which seems to work
fine, but Csound64.dll then seems to reference PortAudio, which it
can't find (when PortAudio is not installed on the computer on which
the application is installed). Csound gives me the message: "unknown
rtaudio module: 'PortAudio', using dummy module".
I have tried adding PortAudio.dll to my application - installed in the
same directory as Csound64.dll - but that doesn't seem to work.

Is there some way to make Csound64.dll search for PortAudio.dll in
it's 'own' directory, or another way to fix this? Perhaps PortAudio
could be compiled into Csound64.dll to have everything 'self
contained'?

Best regard,
Søren

Thanks Mike! yes Csound does still work - there is just no actual
sound. I tried adding PortAudio to Windows\System64 and to set
OPCODE6DIR64 but it didn't help.
I am wondering if there might be other such dependencies from the dll,
and I wonder how I will know what they are (the dependencies may be
present on the machine where I make my test installation, but not on
other machines).
I don't think I will be able to refactor Csound to have the dll
include PortAudio (or other dependencies) - guess for will
(unfortunately) have to ask users of my app to also install Csound
separately.
Best regards,
Søren

I think something to check is if indeed your app is using OPCODE6DIR64
to load rtpa.dll, and that the portaudio dll (not sure the exact name
but it should match with whatever rtpa.dll is linked to) is located
besides rtpa.dll.  You can always use dependency walker
(https://www.dependencywalker.com/) to check linkage. Csound itself
(i.e., csound64.dll) does not have a link to portaudio, just rtpa.dll.
(At one point, all of our libraries were statically linked, but
portaudio might have been a dynamic link.)  I think you should be able
to work out the portaudio issue without having to require Csound be
installed separately.

Thanks for the tips - adding rtpa.dll seems to work:)
I am not sure how those dependency tools would have helped me figure
out about rtpa.dll (they don't work when dll's are loaded in some
specific ways?) - but I probably need to learn better how to use them.
