Here's a full dependency-walker analysis of all w32 v00-extended Deken: http://lucarda.com.ar/x/dep-walk-00extended-deken-w32-report.zip
It's one text file per .dll. We can Grep/Findstring to get results that mainly boils down to: msvcr90.dll -> no match. msvcr71.dll -> Gem and friends. pthread -> splits to: PTHREADGC2.DLL --> some objects. PTHREADVC.DLL --> Gem and friends. We must consider Oliver's discoveries on this: https://lists.puredata.info/pipermail/pd-list/2018-12/124086.html as there's something strange with this file. As of "msvcrt.dll" I think Christof had explained everything. My tests deleting this file showed no trouble. As of "msvcr90.dll" I will randomly search tomorrow on non Pd-extended-era but it could be the case that is not needed, ... Here are the Pd patches I used to generate batch files for dependency-walker and also to serialize opening and closing *-help.pd files: http://lucarda.com.ar/x/w32DekenPKGdepWalkCHECK1.zip @Christof since 2015 there are new runtime libraries, e.g. UCRTBASE.DLL and VCRUNTIME140.DLL (https://en.wikipedia.org/wiki/Microsoft_Windows_library_files#MSVCRT.DLL,_MSVCP*.DLL_and_CRTDLL.DLL) I helped Zack Lee's [ofelia] in the early stage a year ago. Basically there's the normal vc_redist.x86.exe but it does not work on machines that don't receive updates (a minority anyway) but theres is work around shipping a lot of dlls. :) Mensaje telepatico asistido por maquinas.

You should certainly *not* redistribute msvcrt.dll.

I've deleted them from the Pd bin folder and everything works fine on several machines. apart from that, Pd and pure C externals (no matter if compiled with MinGW or VS) only use C functions from the MSVC runtime and this doesn't cause troubles because memory or handles don't cross module boundaries and data structures are well defined. e.g. you must never malloc in one module and free in another because there might be different runtimes involved. C++ externals compiled with MinGW usually link statically against libstdc++ (or ship the DLL) so there are no missing symbols. C++ externals compiled with VS would ideally link statically (see below), but they should *not* rely on a runtime DLL shipped with Pd. if they do, I would reach out to the maintainer or recompile and upload to Deken. so I would say let's get rid of the runtime DLLs in pd/bin. @IOhannes: On 1/22/19 11:36 PM, Miller Puckette wrote: Would this mean that anyone shipping a binary external for Windows would have to put it in a separate directory with its own msvcrt.dll/msvcr90.dll? Sounds like a nightmare to me. but i think that's really the only sane way. unless you can guarantee that Pd and all externals are built with the same compiler. or they can link statically. This is what most VST plugins seem to do. Dependency Walker doesn't show any open dependencies on MSVC runtime libraries on the plugins I've checked. They obviously coexist peacefully in DAWs although they might be from different decades and are mostly written in C++. afaict, Gem really requires to link against msvcrt. using Dependency Walker on the recent Gem 0.94 I see that it only uses C symbols from the MSVC, like any other plugin compiled with MinGW, so I don't see a problem here. the C++ symbols come from the libstdc++ which you ship (although you could also link statically). OTOH, the old Gem from Pd extended depended on C++ symbols from msvcr71.dll (I guess because it was compiled with VS) and if that DLL was missing Gem wouldn't load. Christof Gesendet: Mittwoch, 23.
