Re: [PD] compiling hidio for Windows
Thanks a lot, Christof! This is indeed very helpful. I will let you know what I can find!

Re: [PD] compiling hidio for Windows
Hi, I usually run Pd in a debugger like this: gdb --args pd > run Wait for the segfault. The following will print a stack trace, showing you the function where the segfault occurs: > bt (you might need to hit enter to show additional lines of the stacktrace) From there you can either set breakpoints (https://ftp.gnu.org/old-gnu/Manuals/gdb/html_node/gdb_28.html) or use good ol' printf debugging :-) IDEs like Qt Creator have an integrated graphical frontend for GDB, which makes debugging a more pleasant experience. If you have time, please start investigating! I can have a look (and fix the build system) later this month.

As I said before, I could make a binary with Christof's steps, but I dont know how to debug an external on windows. If you can give me some basic guidelines I can continue with that.

Re: [PD] compiling hidio for Windows
You just have to replace it with #include . I also compiled it with Msys2.

sorry I did not see that. I was reading here the descriptions but I guess it is outdated https://puredata.info/downloads/gem/documentation/manual/manual/list-of-gem-objects . thanks!

[PD] get average luminance of the camera
hi Is it possible to get the average luminance of the camera input using GEM? I am exploring pix_data but as far as I can see it only works with individual pixels. If I could average or reduce the color information from the camera to a single color, then I think I could just take the pix_data grey value of any pixel. But I am not sure this can be done. I am checking different pix_ objects but I dont see how I could get this to work.
