this is odd. I made a simple Pd external which uses s_list and s_signal with MSVC in two versions: one links against Miller's pd.lib, the other links against the pd.lib I get when building from source with MinGW and autotools. Both versions compile, link and load just fine with either Pd version.
I'm using the Developer command prompt, these are my commands: > cl /W3 /DNT /DPD /nologo /I. /IPDSOURCEPATH /c testobj.c > link /dll /export:testobj_setup testobj.obj oldnames.lib kernel32.lib > PDBINPATH\pd.lib Christof Gesendet: Mittwoch, 23.

Why? I used these variable because I assumed that they are more efficient than using `gensym()` (and as they are defined EXTERN I also assumed that they can be used). But yes perhaps a better solution would be to generate and store the symbols in the new method of the object using `gensym()` (and it will be the same but for the sustainability of old codes, these symbols must be included).

I can help if needed. _______________________________________________ Pd-dev mailing list Pd-dev@lists.iem.at[mailto:Pd-dev@lists.iem.at] https://lists.puredata.info/listinfo/pd-dev _______________________________________________ Pd-dev mailing list Pd-dev@lists.iem.at https://lists.puredata.info/listinfo/pd-dev[https://lists.puredata.info/listinfo/pd-dev] _______________________________________________ Pd-dev mailing list Pd-dev@lists.iem.at https://lists.puredata.info/listinfo/pd-dev
