hey folks! i've recently run into a situation in which i have to recompile an external currently only available for mac ("pd_darwin") to a Windows platform. the code was ported from the original C/C++ code of the Mutable Instrument module called Plaits. basically it's just a release of the DSP code as a PD object. it's hosted here:

https://github.com/jnonis/pd-plaits

he's including the xcode project but i believe the code itself is just straight .cpp files wrapped into the PD external template code. i think he's using the pdlibbuilder library that's been recently released, but i have had absolutely zero experience with compiling the source for different platforms. the meager amount i know is you use a command line and probably the Makefile but i know some of you have done this, and so i'm wondering what one should do to compile this for a Windows build. shoutout to @porres for some help (since you did the ELSE libraries) do i need to use/install MinGW? i have a macOS and Windows 10 machine, but if i recall it's not necessary to have a Windows box to compile a DLL for that platform. anyway, any help appreciated!

I use MinGW to compile on a windows machine, but my project is not based on XCode at all

MSYS2 is the new standard last time I checked. You can follow along with the purr data build guide to guarantee the right dependencies get installed. You only need to go as far as step 4, and you can also skip the inno setup if you're just building externals.

I went ahead and built plaits for 32-bit pure data. Hopefully that works for you.

When building it, I needed to change one thing in the Makefile. See that line where it says:

cflags = -DTEST -Wno-unused-local-typedefs -I./

That doesn't work. -I./ needs to be changed to the absolute path that your plaits project happens to be in. For example, mine looked like this:

cflags = -DTEST -Wno-unused-local-typedefs -I/c/Users/myQwil/Desktop/pd-plaits-master
