you need to be aware of the version at compilation time, and have to use this version at runtime. So I don't think you can build an external that would be compatible for both versions.
why?
Because interfaces changed :
-void iemgui_save(t_iemgui *iemgui, t_symbol **srl, int *bflcol) +void iemgui_save(t_iemgui *iemgui, t_symbol **srl, t_symbol**bflcol)
[...]
so how could I build a binary that would switch the interface of iemgui_save at runtime, following the version of the running Pd ?
in pseudo code: if(pd<0.47) iemgui_save(x, srl, i_color); else iemgui_save(x, srl, s_color);
this will give you some compiler warnings, but you can do:
typedef void(t_iemgui_save_old*)(t_iemgui *iemgui, t_symbol **srl, int *bflcol); typedef void(t_iemgui_save_new*)(t_iemgui *iemgui, t_symbol **srl, t_symbol **bflcol);
if(pd<0.47) { t_iemgui_save_old isave=(t_iemgui_save_old)iemgui_save; isave(x, srl, i_color); } else { t_iemgui_save_old isave=(t_iemgui_save_new)iemgui_save; isave(x, srl, s_color); }
