I have been investigating the opcodes that have been moved from
csound/csound to csound/plugins and have hit a number of problems.


1: make install on the MAC was total rubbish.  I have made some
adjustments but cannot verify the fixes.

2; The python opcodes fail totally in response to a make.  It does
nothing and the README.md file offers no clue.  Anyone who understands
the python subsystem and has got some time care to fix?

3: I cannot check the Ableton link opcodes nor the faust ones.  So far
I have not managed to install the dependencies.  As in 2 anyone know how
to fix?

4: image opcodes build OK on Linux and run, but seem to be broken on
MacOS.  Help most welcome.

5: chua build ad ran on Linux

6: widgets in FLTK seem OK on Linux but remain problematic in MacOS

7: No idea what happens with windows.

No doubt there are other issues.

Back home now. Let’s see, I’ve pulled the latest code and I can do

$ mkdir debug
$ cd debug
$ cmake .. && make


and build all targets for which I have dependencies installed and enabled:

-- BUILD_CHUA_OPCODES is enabled.
-- Found FAUST: /usr/local/lib/libfaust.a  
-- Found OpenSSL: /usr/local/lib/libcrypto.a (found version "1.1.0e")  
-- BUILD_FAUST_OPCODES is enabled.
-- Found ZLIB: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.3.sdk/usr/lib/libz.tbd (found version "1.2.11") 
-- Found PNG: /usr/local/lib/libpng.dylib (found version "1.6.6") 
-- BUILD_IMAGE_OPCODES is enabled.
-- Found PythonLibs: /Library/Frameworks/Python.framework/Versions/3.9/lib/libpython3.9.dylib (found suitable version "3.9.6", minimum required is "3") 
-- BUILD_PYTHON_OPCODES is enabled.

I’m actually not very well versed on CMake install targets, so I can’t offer much help right now.

This is building correctly from the toplevel cmake .. && make. You need to have Python 3 development libs 
installed. On a Mac, it suffices to install Python 3.x from python.org


> 3: I cannot check the Ableton link opcodes 

Never built these, so I can’t help there. They have never been distributed on the Mac installers

> the faust ones.  So far

Faust can be installed from sources (or from binaries) https://faust.grame.fr/downloads/

This one is an easy one to provide a release, it uses a static faust lib which I have here
and so the the dylib on its own is all it’s needed. I can build it here as I demonstrated above.

>

Again, builds here. I suspect this has to do with dependencies. I don’t know off the top of my
head what they are, but it should say in CMakeLists.txt

> 5: chua build ad ran on Linux

Builds and runs here.

> 6: widgets in FLTK seem OK on Linux but remain problematic in MacOS

These will never work on MacOS because of threading issues. We cannot use them on that system 
and there is no solution for it.

> 7: No idea what happens with windows.

CMake should work on Windows as well.

> 
> No doubt there are other issues

Agreed. It wasn’t for nothing that we put these libraries out of the main Csound repo. They are a never ending source
of problems because of dependencies and code that is not maintained by its original developers. I can build
all of the libs for which I have dependencies but I can’t easily produce an installer because of having to
provide the dependencies for these in the appropriate location, and with all the link names correctly set.

Clearly the docmentation needs to say smething about the dependancies. 
But still not building

possibly your cmake cache is all messed up. Try this, from the top level plugins repo
