I would also suggest putting important platform-specific stuff with the sources in msw/README.txt. > On May 19, 2023, at 12:00 PM, pd-dev-request(a)lists.iem.at wrote: > > Message: 3 > Date: Fri, 19 May 2023 09:17:57 +0200 > From: Pierre Mallard <mallard.pierre(a)gmail.com <mailto:mallard.pierre@gmail.com>> > To: Christof Ressi <info(a)christofressi.com <mailto:info@christofressi.com>> > Cc: pd-dev(a)lists.iem.at <mailto:pd-dev@lists.iem.at> > Subject: Re: [PD-dev] Compiling debug mode for GDB on MSYS2 MINGW64 > Message-ID: > <CAKODt8xPxkv=mC9t9fU6LfY=bfOi651E55u5RoTx73tAXuEMyQ(a)mail.gmail.com <mailto:CAKODt8xPxkv=mC9t9fU6LfY=bfOi651E55u5RoTx73tAXuEMyQ@mail.gmail.com>> > Content-Type: text/plain; charset="utf-8" > > Hello Chris and everyone, > > Thanks for the trick, it could be nice to complete the wiki on > http://puredata.info/docs/developer/BuildingPd with at least your approach > (mine would require to patch msw/Makefile.am) > Let me know if it is worth it, I don't have an account there. > > Bye -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

compiling externals for FreeRTOS
by Alexandre Torres Porres 22 May '23

Hi, for a project with friends I'm gonna try and dig pd for freertos and esp32... so I wonder, how crazy would it be to compile externals for it, like quite simple ones coded in plain c, no great dependencies? thanks

Compiling debug mode for GDB on MSYS2 MINGW64

Hello everyone, I have been struggling a few days to achieve using gdb on msys2 mingw64. In case anyone is interested, here is how I finally succeed in using gdb. Note that I am a newbee on both autotools and pd so maybe there is a much more straightforward way to do so. Edit msw/Makefile.am to add -n for non stripping binaries : ... $(SH) $(top_srcdir)/msw/msw-app.sh -n --sources --builddir $(top_builddir) $(VERSION) ... Type following commands $ ./autogen.sh $ cd build $ ../configure --enable-debug CFLAGS="-g" $ make $ make app The generated pd.exe in pd-0.53.1 directory correctly execute but with no symbol in it. To retrieve symbol use libtool --mode=execute as follows : $ libtool --mode=execute gdb --args pd-0.53.1/bin/pd.exe ... Reading symbols from pd-0.53.1/bin/pd.exe... (gdb) b main Breakpoint 1 at 0x140001464: file ../../src/s_entry.c, line 30. (gdb) And this is it ! I'm using following pure-data sources : branch master, last commit : commit 3fde7100fcfb8fd0debb4e5f1b4c264e053a6254 Thu Apr 20 16:36:54 2023 +0200

Re: [PD-dev] problem loading tcl tk plugin with binary
by Dan Wilcox 15 May '23

I agree. If you just need access to the popup menu, you can support both old versions and the new global popup by first checking the pd version or available of .popup (ie. check if it exists) and use the one available to the version. There are various examples of this in the Pd tcl sources, ie. checking Tcl/Tk versions or checking if a name or variabel exists before creating or trying to use it, etc. I also agree about the issue: it's likely the plugin may be trying to grab stuff that just isn; y there yet. I would move part of this setup stuff to something later in the process, ie. perhaps a lazy-creation proc which gets the plugin popup reference and sets the value from the global instance if it doesn't exist yet. > On May 15, 2023, at 10:08 AM, pd-dev-request(a)lists.iem.at wrote: > >> So, I'm not sure I get it but I'm assuming this won't be an issue in the >> next version, right?

problem loading tcl tk plugin with binary
by Alexandre Torres Porres 15 May '23

Hi, I have a test release for ELSE up in deken and I'm trying a new thing where it loads a tcl tk plugin when you load the library via the startup path. The plugin is an object browser that creates a drop menu when right clicking on a canvas, like the one I did for vanilla and you can get it. The release is marked as "else rc8 test" and you can get it. The binary code is in https://github.com/porres/pd-else/blob/master/Classes/Source/else.c and you get with the download a couple of tcl files, which are https://github.com/porres/pd-else/blob/master/extra/else-browser.tcl and https://github.com/porres/pd-else/blob/master/extra/else_tree.tcl It seemed to work fine for me and others, I tested on old macbook aur from 2013 with mojave. It doesn't work on a 2018 intel macbook pro with mojave as well, and gives this error. The file is found and loaded, *ELSE's object browser-plugin loaded via the 'else' binary* but I get this tcl tk error right after *(Tcl) INVALID COMMAND NAME: invalid command name ".popup" while executing"$mymenu add separator" (procedure "category_menu::create" line 3) invoked from within"category_menu::create .popup" ("eval" body line 55) invoked from within"eval [read [open [file join /Users/ale/Documents/Pd/externals/else else-browser.tcl]]]" ("uplevel" body line 51) invoked from within"uplevel #0 $docmds"* The thing is that if I load it as a proper tcl tk plugin it works when laoding Pd, and it also works ok if I load the else binary not on the startup but with decalre, for instance... To make things even crazier, the same macbook pro on another partition with monterey loads it just fine! tested with Pd 0.52-2 realy lost here so I hope the wizards could help me thanks
