Hi, i'm relatively new to Pd but I have been slowly making my way trough tutorials and information given trough the forums. I'm interested in pitch detection functions and i found the helmholtz~ object by Katjav.
i've been trying to compile the file using Msys2 , with no success , I don´t have no experience working with C + but after installing Msys2 and following the instructions I still canot have it working mainly because i'm not sure what does each line really means, I imagine it's really basic stuff but i'm lost .
Does anyone have a built up version for windows 64bit or can help me with a more precise step by step instructions?

thanks a lot

here are the instructions

Open the Makefile in helmholtz~/src and edit the target suffix to match your system: (in which program am i suppose to pen the file?)

pd_darwin for OSX
pd_win for Windows with MinGW
pd_linux for Linux

For 64 bit systems, flag -fPIC may be added to compiler flags. /how to I apply the flag?)

In terminal, cd to directory helmholtz~/src and type 'make'. The binary is copied to directory helmholtz~/ and you can use it from there or copy it to a directory in Pd's path.

Don't have Windows, so can't help with compiling [helmholtz~], but Pd has its native [sigmund~] which does pitch detection. Check its help patch, it's likely it will do for what you want.

thanks for the reply
i have been using sigmund~ i was just curious about helmholtz~ because it said that it is more precise in the pitch detection,

It is definitely a lot more stable for certain scenarios. For using strings, for instance.

Use Pd-Lib-Builder; it's very easy to use:

We ported helmholtz~ to Max a while back on Windows and macOS:

Did you get this working? I have a very quick and dirty solution for you. pd-lib-builder takes care of just about everything when you run make but you'll still need to link Helmholtz and helmholtz~ together manually. It'll probably look something like this:

g++ -static-libgcc -static-libstdc++ -shared -Wl,--enable-auto-import "C:\Program Files/Pd/bin/pd.dll"    -o helmholtz~.dll helmholtz~.o Helmholtz.o

That's pretty much all pd-lib-builder, with the one manual part being the Helmholtz.o at the end of the statement.

Anyways, here's a zip of that project folder, where you'll also find a 64-bit build. I haven't really played around with it much but it seems to be working just fine.

helmholtz~.zip

Just as an addendum, you can probably get pd-lib-builder to link the files on its own by removing helmholtz~.cpp from class.sources and adding:

make-lib-executable = yes
lib.setup.sources = helmholtz~.cpp

Thanks a lot for the replies and for sharing the project.
I had given up from using the pd-lib-builder because i feel i don´t have yet the basic notions to follow the instructions , even though they were very simple. i guess i need to go back to the basics. i think i don´t even have Pd-Lib-Builder well installed.

but well, i truly appreciate your answers and helmholtz~ is working fine.
