Purr Data 2.5.0 is now available:

https://github.com/jonwwilkes/purr-data/releases/tag/2.5.0

Please report bugs here:

https://git.purrdata.net/jwilkes/purr-data/issues

Changes:

• add pd-lua library
• fix up dialog styling for GUI presets
• expand help browser search index to include the external library docs
• add preferences for setting when and from which docs the search browser creates an index
• port disis_munger~ to Purr Data from pd-l2ork 1.0 (experimental)
• fix the build scripts by adding toplevel makefile with new targets
• fix uninstall icon on Windows
• add dashed box around comments when in edit mode to show the maximum space they will take up

Thanks @jancsika!
Given some advancement in pd for win64 can we hope for a not so distant future for a Purr Data win64?
best!

@alfonso.santimone Is it a fully-functioning, stable w64 Pd release or a work-in-progress?

@jancsika actually there is a test version of vanilla by Miller. It has some problem about Portaudio. But at the pd mail list Lucas Cordiviola compiled a workin' version with MSYS2. I'm using it recently and everything seems to work until now. Anyway 64 bit is the standard for Windows system. More and more developers are adbandoning 32bit.

@alfonso.santimone Does Portaudio still have problems under Lucas' version?

@jancsika Lucas' version is perfectly working i can use ASIO drivers so the Portaudio is working.

@alfonso.santimone If you can link to instructions on what he did to get this working version I'll look into getting Purr Data running as a 64-bit binary on Windows.

@jancsika where can i send you a pdf with my mail exchange with Lucas? In the last two messages Lucas gives some instruction. Let me know of any help you may need.

@alfonso.santimone Can you just paste the relevant info here? Or on the l2ork dev list?

http://disis.music.vt.edu/cgi-bin/mailman/listinfo/l2ork-dev

@jancsika here is a link with some instructions by Lucas
http://puredata.info/docs/developer/win/WindowsMinGW

And some extract from my mail exchange with Lucas

"For building a w64 Pd we open the MinGW64 shell and do:

./autogen.sh

./configure CPPFLAGS=-DPD_LONGINTTYPE=__int64

make

Note the preprocessor flag: CPPFLAGS=-DPD_LONGINTTYPE=__int64

This flag is also needed to compile externals.
Once built you should copy from the compiler the 64bit version of "libwinpthread-1.dll" and for the case of Purr-data I'm not sure if other dlls are needed to run.:

"libstdc++-6.dll" ?
"libgcc_s_dw2-1.dll" ?
"

Can I considered these lines as additional instructions for the "standard" compiling instructions?

I have updated http://puredata.info/docs/developer/win/WindowsMinGW

Note that is for Pd. I think this is the same for purr-pata. You should check with Jonathan.

So where I have to copy the dll? In windows/system32 folder?

They should be fine in the same dir as pd.exe.

I guess this is due to the fact that Pd can't statically include those libs?

Msys2 can statically include those libs but is better to check this with Jonathan. On my humble opinion on compiling I believe that purr-data don't need to be "statically linked".

@alfonso.santimone I need to install a new Windows VM for the Purr Data continuous integration builds, so I can certainly set one up to try to build a 64-bit binary. But I have no way to test it (nor any interest in testing it).

Are you willing to test it?

@jancsika sure! i can test it!

@alfonso.santimone Oh wow, a Windows 10 VM can't even run on my build machine! It's eating the entire system's memory-- I couldn't even ssh into it and had to reboot.

I could probably cross-compile on the Windows 7 VM. But I wouldn't be able to run tests so that isn't ideal.

Anyway, if you want to try compiling yourself, you can use the instructions from the 32-bit build as a guide:

https://git.purrdata.net/jwilkes/purr-data#windows-32-bit-using-msys2

You'll have to change some of the instructions and download the corresponding msys2 64-bit packages. You'll also certainly run into crashers because the Makefile for windows currently installs some 32-bit dependencies manually into the Purr Data installer package. But if you get that far I can guide you through the solutions to most of those problems.

The good news is that you don't need Lucas' preprocessor flag because we already have an ifdef for Windows 64 big in our build system.

If you can get through all that it would help the project: I could add instructions for a 64-bit Windows build and fix up the windows Makefile so it works for 64-bit. (The GUI we ship on Windows is already 64-bit so that's ready to go.)

@jancsika As soon (still some days to go) as i can free some space on my W10 audio workstation SSD i'll reinstall all the developing tools i use to have on my Win7 and i'll try to do some compiling. Given that the next milestone for Camomile by @Pierre-Guillot is to include external libraries i guess it can be helpful to compile even the 32bit only libraries for 64bit

@jancsika now i have a minGW 64bit working enviroment via MSYS2 (64 bit version)

i wonder how and where to find 64 bit versions of this packages

i guess they are living here
http://repo.msys2.org/mingw/x86_64/
i try to modify the names like this
mingw-w64-x86_64-fftw etc. etc.

@jancsika yeah i correctly installed all deps but when i build i have this error
