Of course realtime audio is just a matter of writing

Subject: [Csnd] Re: Plugins not loading on Solaris


I was looking through the plugin loading code in Csound today and remembered
this problem that Sergio was having.  The answer to why none of the plugins
are loading is that there is no plugin support for Solaris!

Csound only has code for loading plugins on Windows, Linux, MacOS X, and
MacOS 9.  When compiled on any other platform, it uses a dummy function for
csoundOpenLibrary() that always returns -1 -- thus the error message.  (See
line 1176 in Top/csmodule.c).

The solution is to do one of the following:

a) If Solaris uses the same methods for loading modules that Linux does,
then change the #elif defined(LINUX) on line 899 of csmodule.c to include a
test for Solaris too.  (Might be prudent for us to add tests for BSD Unices
as well if appropriate).  Also, the #if defined(LINUX) tests on line 81 and
in csoundLoadExternal() should probably be changed (?).

b)  Otherwise, a new #elif case needs to be added with Solaris-specific
versions of the functions csoundOpenLibrary(), csoundCloseLibrary(), and
csoundGetLibrarySymbol().

Other factors should also be checked, such as the assumptions in
csoundLoadModules() about filename extensions for plugin libraries (line
673).

There may be many other parts of Csound 5 that test for LINUX when what is
really meant is "any non-MacOSX Unix".  It may be expedient to simply define
LINUX during the build process on Solaris or BSD but I do not know for sure
that this will work.  It would be nice if Csound 5 would gracefully build on
these platforms, supporting the features that it can and ignoring those it
cannot (like real-time audio?).

Sure.  I just meant that there was probably no support for real-time in
Csound 5 on Solaris or BSD at the moment.  AFAIK, PortAudio v19 does not
support them.  There was real-time code in Csound 4 for Sun, HP, and Next
that could be turned into plugin modules I suppose (if it is up-to-date).

Hi all,

Thank's for all your replies.

First i intend to try the way which seems easyst : declaring my get.platform
as linux in the main Sconstruct file and adapting several pathes etc.

After that i'll report the results in this forum and, if has not worked,
look in the code files as explained Anthony.

Cheers,

Sergio

Hi all,

First i tried to declare my platform as "linux" : il builded all, but the
plugins are allways unloadable.

After that, assuming that in csmodule.c the choice is "if defined ..." and
not "if get.platform...", i removed the Win32 part and the OSX part : in
this case it's possible to remove also the "if defined LINUX", so any system
must be concerned by the plugins load procedure in csmodule.c. I made that,
but same result : the build passed OK, but plugins again unloadable.

Best regards,

Sergio
