Building Tartini on Debian

Tartini is a cool real-time "music analysis" program (http://miracle.otago.ac.nz/tartini/index.html).  The issue is that the sources don't immediately compile on my Debian system.

UPDATE: I've actually gone through and fixed all the issues and created a Debian package for it.  You can download the source at https://github.com/jeremysalwen/tartini-debian  Hopefully it will be in debian too soon.

Obviously, as the instructions say, qt 4, fftw 3, and qwt 5 must be installed for it to compile.  Installing the packages fftw3-dev and libqt4-dev is straightforward.  Make sure that if qt3 is installed, all of the build tools point to the qt4 versions. However, be careful with qwt, as the debian repositories contain a package "qwt-dev" which is not version five.  Instead, install libqwt5-qt4-dev.


As the build instructions state, you then have to modify pitch.pro to tell it where the includes and libraries are.  On a typical debian system, the important part of the file should look like:

unix{
  macx{ #MacOSX
    MY_LIB_PATH += -L/Users/student/usr/local/lib
    MY_INCLUDE_PATH += /Users/student/usr/local/include
  }else{ #Linux
    MY_LIB_PATH += -L/usr/lib
    MY_INCLUDE_PATH += /usr/include/qt4 /usr/include/qwt-qt4 /usr/include
  }
}

Then, qmake will still give you the error

RCC: Error in 'pitch.qrc': Cannot find file 'pics/tartinilogo.png'

For some reason it's looking for a png when the file is really a jpg.  Just modify pitch.qrc to replace tartinilogo.png with tartinilogo.jpg

qmake will then work, but make will still complain about

error: invalid conversion from ‘const char*’ to ‘char*’

a bunch of times.   mystring.cpp and mystring.h are the offending files.  Basically there is a bunch of code that seems to be just *wrong* in how it handles constness.  If you make the local variable "char * ext;" into "const char * ext;" in two functions, and make getFileExtension return type "const char*" instead of "char*", it will work.  (don't forget to change the function in both the cpp and the header file.

Meanwhile, prony.cpp gives a cryptic warning about the included file "cstdio", which seems to be caused by the line:
#define _GLIBCXX_USE_C99

I am not really sure if this affects the functionality of the code, but when I comment it out, it compiles and runs fine.  Apparently there is strange functionality surrounding this symbol anyway: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=443234

You will also get a linking error because it tries to link with -lqwt, when the qwt5 package only provides qwt-qt4.  Again, under the linux section of pitch.pro, replace the line

LIBS += $$MY_LIB_PATH -lfftw3f -lqwt -lasound

with

LIBS += $$MY_LIB_PATH -lfftw3f -lqwt-qt4 -lasound

Still, when you build it, it segfaults when you try to run fixing up calculateAnalysisData in mytransforms.cpp, we replace

if(chunk > 0 ) {
with

if(chunk > 0 && prevAnalysisData->highestCorrelationIndex!=-1) {

To stop the segmentation fault if the previous highest correlation index is -1 (not found).

And that should be enough to get a working Tartini build on Debian.  I would post a diff or a zip of all the corrections, but I can't attach it here.
