[PD-dev] Compiling an external with stdc++ on Linux

[Pierre Guillot]

I found the solution! I was linking the external with stdc++ but in fact I
must link the FAUST library with stdc++. Now, there are 2 more "implicit"
dependencies libz.so and libtinfo.so (and libstdc++.so) that seem to fix
the problem and  it works!  I will publish the new version v0.0.2 (with the
Linux fix) on Deken today (there is already the version 0.0.1 that works on
Mac & Windows 64bits on Deken). I'll keep you informed when the version
will be available on the pd-announce list .
Cheers,

Pierre
