Hey hey,
I noticed that I have a small issue with csound and opcode libraries. 
Something like this appears when typing:
$ csound -z
WARNING: could not open library '/usr/lib/csound/plugins64-6.0/libelse.so' 
(/usr/lib/csound/plugins64-6.0/libelse.so: undefined symbol: __pow_finite)

This message is repeated for:
libhdf5ops.so
libwebsocketIO.so

Apparently the required libraries libhdf5.so and lib websockets.so aren't 
found, although they are installed on the system. All involved packages were 
installed through my system package manager (ArchLinux pacman).

Can anyone suggest a solution?

If that might be indicative: having installed risset, I had issues, because it 
only looked at /usr/local/lib instead of /usr/lib .  In the shell environment 
the OPCODE6DIR points to /usr/local/lib/csound/plugin64-6.0 .

Best wishes,

Jeanette

Well, the libelse.so I just installed and wanted to try. The hdf5 and

Your installation is somewhat confusing: csound on linux is hardcoded to default to /usr/local/lib, so you've changed that. Besides that OPCODE6DIR should have no influence since you are using a doubles build.

You can build the plugins yourself.

git clone https://github.com/csound-plugins/csound-plugins
cd csound-plugins
mkdir build
cd build
pacman install nasm
cmake ..
make -j8
sudo make install

You can set the installation path of Csound to be /usr instead of
/usr/local, which is usually done by package managers.

It is not **my** assumption, look at Top/csmodule.c

Btw, I strongly advice against such assumption "csound on linux is hardcoded to default to /usr/local/lib," about any linux software. An installation directory defaults to prefix path used during installation, wherever that may be. Relying on absolute installation paths makes installations impure and non-posix compliant.

Just for clarity (though you probably know already) these errors happen
when a plugin needs another (usually system) library that supplies that
symbol.

However, some quick investigation shows that libelse.so only wants
libc.so.6, which I'd guss is already in your system -- it certainly is
on mine!  And indeed, libc does not supply '__pow_finite'! I wonder
what system libelse was built for?

looks like you'll need to build it yourself as suggested.

Cheers,

Thanks Steven and all of you. Should OPCODE6DIR64 be set somewhere in
the cmake configuration process? I'll be happy to pass it on.

Best wishes,

Now risset looks first at OPCODE6DIR64 and uses that if defined. On linux it then looks at /usr/local/lib/csound... and if not found looks at /usr/lib/csound/...

But all this would be much easier if csound had a default search path for user plugins. Then we wouldn't be having this conversation.

There's also this in CMake

if(BUILD_RELEASE)
    add_definitions("-D_CSOUND_RELEASE_")
    if(LINUX)
        set(DEFAULT_OPCODEDIR "${CMAKE_INSTALL_PREFIX}/${PLUGIN_INSTALL_DIR}")
        add_definitions("-DCS_DEFAULT_PLUGINDIR=\"${DEFAULT_OPCODEDIR}\"")
    endif()
else()
    add_definitions("-DBETA")
endif()

And it's unknown whether packagers may or may not override CS_DEFAULT_PLUGINDIR. 

Probably makes sense to check the environment variables for OPCODE6DIR64 too for where to install opcode libraries.

Arch's package does look like it needs to be fixed to set OPCODE6DIR64.

thanks for telling me, there's a lot of dirty work that needs to be done, so my nagging is justified, just need to direct it correctly, and I should mention, that debugging problems from installation directory makes total sense.
