Thanks for the information, we will try with a SharedObject target -- though I'm not sure that will work on Windows. Of course, it is always possible to get SCons to recognize a nonstandard library name.

Regards,
Mike

I think it could have been enough to just build commands.c as a SharedObject,
and adding that to the sources of all three targets. Linking to tclcsound.so
does not work on Linux because it uses a non-standard name (i.e. no 'lib'
prefix), and it also requires installing the library to a directory where it
is found by the dynamic linker at run-time.

Hi everyone,

I installed Csound5.02.1 on a linux computer with Scons. The  
installation was succesful but when i tried to lauch the application  
i got this message:

"
csound: error while loading shared libraries: libsndfile.so.1: cannot  
open shared object file: No such file or directory
"

I set OPCODEDIR=/usr/local/lib/csound/plugins

That didn't change anything.

Any Ideas?

Thanks

Olivier

First and obvious question; do you have a copy of libsndfile.so?
Second obvious question; if you do, is it in your load path?

Hi Olivier,
Seems like you need to add the path for /usr/local/lib to the dynamic 
linker.
Add to /etc/ld.so.conf the following line (must be root):
/usr/local/lib/
Than run as root (configure dynamic linker run time bindings):
ldconfig
