Hi François,

I updated my faust2 build from GIT and it did not have the Soundfile interface you are mentioning here,
so I could not build the file. I am not sure what is going on. For the moment, I’ve added a forward
declaration for struct Soundfile in order to compile. Do you know anything about this mismatch
of interfaces?

thanks

I understand this, but then if I build the opcodes with that, I get

/Users/victor/src/csound6/Opcodes/faustgen.cpp:93:48: error: unknown type name 'Soundfile'
  virtual void addSoundfile(const char* label, Soundfile** sf_zone) {};
                                               ^
1 error generated.

I pulled faust this morning and the UI.h file I have is different from this one.

Actually, I noticed the change in git address, so I got the new code now. However, this appears to have changed significantly and it will not compile
the faust opcodes now.

Ok, I was in the wrong branch. The interface changed again, the function signature is now:

virtual void addSoundfile(const char* label, const char* filename, Soundfile** sf_zone) {};

it is compiling OK. You might want to update your faust build.

thanks, I was in the master git branch rather than faust2.

I installed LLVM 5 by untarring in usr/local and pulled faust2 and
built it. I had to adjust the CMake parameters as follows to build
Csound develop head with gcc and the Faust opcodes:

cmake ../csound -DSCORE_PARSER:BOOL=Yes
-DABLETON_LINK_HOME:PATH=/home/mkg/link
-DBUILD_ABLETON_LINK_OPCODES:BOOL=Yes -DBUILD_STATIC_LIBRARY:Bool=Yes
-DBUILD_TESTS:BOOL=Yes -DCMAKE_BUILD_TYPE=RelWithDebInfo
-DBUILD_HDF5_OPCODES:BOOL=Yes
-DVSTSDK2X_HOME:PATH=/home/mkg/VST_SDK/VST2_SDK
-DBUILD_CSOUND_VST:BOOL=Yes -DBUILD_VST4CS_OPCODES:BOOL=Yes
-DLLVM_DIR=/usr/local/lib/cmake/llvm -DCMAKE_MODULE_LINKER_FLAGS="-L
/usr/local/lib" -DFAUST_LIBRARY=/usr/local/lib/libfaust.a
-DBUILD_FAUST_OPCODES:BOOL=Yes

Everything built without error. Unfortunately the manual example for
faustgen failed with this error:

I installed LLVM 5 by untarring in usr/local and pulled faust2 and
built it. I had to adjust the CMake parameters as follows to build
Csound develop head with gcc and the Faust opcodes:

cmake ../csound -DSCORE_PARSER:BOOL=Yes
-DABLETON_LINK_HOME:PATH=/home/mkg/link
-DBUILD_ABLETON_LINK_OPCODES:BOOL=Yes -DBUILD_STATIC_LIBRARY:Bool=Yes
-DBUILD_TESTS:BOOL=Yes -DCMAKE_BUILD_TYPE=RelWithDebInfo
-DBUILD_HDF5_OPCODES:BOOL=Yes
-DVSTSDK2X_HOME:PATH=/home/mkg/VST_SDK/VST2_SDK
-DBUILD_CSOUND_VST:BOOL=Yes -DBUILD_VST4CS_OPCODES:BOOL=Yes

/usr/local/lib" -DFAUST_LIBRARY=/usr/local/lib/libfaust.a
-DBUILD_FAUST_OPCODES:BOOL=Yes

Everything built without error. Unfortunately the manual example for
faustgen failed with this error:

1) Download a zip file of faust2 from https://github.com/grame-cncm/faust/tree/faust2

2) Unzip and build faust (make & sudo make install)

3) Pull csound sources from github

3) Build csound

My cmake command for csound is;

Actually, I noticed the change in git address, so I got the new code now. However, this appears to have changed significantly and it will not compile

the faust opcodes now.

I pulled faust this morning and the UI.h file I have is different from this one.

Hi François,

I updated my faust2 build from GIT and it did not have the Soundfile interface you are mentioning here,

so I could not build the file. I am not sure what is going on. For the moment, I’ve added a forward

declaration for struct Soundfile in order to compile. Do you know anything about this mismatch

of interfaces?

thanks

I solved the problem by adding the following line to faustgen.cpp (89):

virtual void addSoundfile(const char* label, Soundfile** sf_zone) {};
