Dear Csounders,

I try to compile a single cpp file but I get an error ("CppSound.hpp not
found"; but the file exists). Could you help me please? I have probably
forgotten something...

COMMAND LINE (from Rory Walsh, Developing Audio Software with the Csound
Host API):

Try -I "/home/olivier/paquetages/Csound5.18.02/interfaces"

CppSound lives there if you are working from your own build of Csound.
If you are using one of the Linux installer then it should live in
/usr/local/include/Csound I think?

Thank you Rory. I tried:

-I"/home/olivier/paquetages/Csound5.18.02/interfaces"

Now, I get another error:

OK. That is better with the command line below. But I get a library error
that I do not succeed to do.

My usual linker options on Linux are

-lcsound64 -lm -lsndfile

The -lsndfile should sort the most recent problem you are having.

-lsndfile is needed.

Compilation is OK with:

g++ cstestapi.cpp -o testapi -I"/home/olivier/paquetages/Csound5.18.02/H"
-I"/home/olivier/paquetages/Csound5.18.02/interfaces"
-L"/home/olivier/paquetages/Csound5.18.02/" -lcsound64 -lcsnd -lsndfile
-lpthread -lgomp -ldl

I don't know why I have to add "-lsndfile -lpthread -lgomp -ldl"... but it
works!

NOW: ERROR AT EXECUTION, libcsnd not found...

./testapi: error while loading shared libraries: libcsnd.so.5.2: cannot open

When you built Csound did you add the buildInterfaces=1 option?

The library is there, since you've built your program. It's just no in the search path for .so. Try installing it in /usr/local/lib and running ldconfig afterwards.

That works when I put a symbolic link to libcsnd.so.5.2 into the /usr/lib64
folder.

Merci beaucoup !
