[linux-audio-dev] DSSI .so C++ problem 2.nd try

Hi, there's a serious typo in my previous mail, please ignore it and read this one. Sorry for the duplicate. i'm currently investigating making LDrum a DSSI instrument. Therefore i made a simple and nearly empty DSSI header to test it with the dssi_example_host. I encountered some C++ problems but after putting the extern "C" stuff in place, dssi_example_host recognizes and starts my empty instrument :) So i went on and started including some LDrum headers... and that broke the instrument :( dssi_example_host no longer recognizes nor starts it. After hours of digging i'm finally stuck, because of another C++ problem. Here's what happens: When I use my instrument code which is nearly empty and which does not include any LDrum headers (that is: headers which include C++ code) everything works fine. By simply adding the following include: #include <iostreamthe instrument is broken. It is no longer recognized. This only happens with iostream. Other headers like string or vector work fine (since these are all templates no library should be required, right?). I used 'nm' to grep for unresolved symbols in my instrument .so and when including iostream there are some strange ones popping up (ios_base). Instrument plugin without '#include <iostream>' U __gxx_personality_v0 U calloc U free U malloc Instrument plugin with '#include <iostream>' U _ZNSt8ios_base4InitC1Ev U _ZNSt8ios_base4InitD1Ev U __cxa_atexit U __dso_handle U __gxx_personality_v0 U calloc U free U malloc Can anybody tell me what I'm missing?
