Hi Igor,
I just attempted to build a package for Arch Linux (AUR) but with the current build system it seems to be a non-trivial task.
I guess it's no easier for other distributions.


main.cpp: In function ‘int main(int, char**)’:
main.cpp:133: warning: ‘jack_client_t* jack_client_new(const char*)’ is deprecated (declared at /usr/include/jack/jack.h:99)
vproc_dsp_process.cpp: In member function ‘void mydsp::setPitchFactor(float)’:
vproc_dsp_process.cpp:200: warning: ‘curr’ may be used uninitialized in this function

Regards,
Philipp
