Hi,

I built Csound 6.08 and am making some tests.  When I try to "import ctcsound" from the first ctcsound cookbook, I get the following error:

OSError                                   Traceback (most recent call last)

Any help would be appreciated.

Looks like you don't have glibcxx 3.4.21 in your system.

Victor,

Thank you for this.  It was actually a mismatch of versions.  It wasn't a clean solution but the version of libstdc++.so.6 that was running in anaconda/ipython was not the version that was needed to run csound.  I corrected this by deleting the link and creating a another one to the libstdc++.so that was in /usr/lib.

$ ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6  /home/mitch/anaconda3/lib/libstdc++.so.6

Mitch
