[PD] Linking externals on windows with mingw32

[Christof Ressi]

Hi, could be a problem with your linker flags. Try these:

gcc -static-libgcc -shared -Wl,--enable-auto-import "/c/pdbinpath/pd.dll" -o foo.dll foo.o

I basically took the linker flags from pdlibbuilder. I generally recommend this tool for building externals because it's cross platform and really convenient.

Betreff: [PD] Linking externals on windows with mingw32

 
Hi list,
 
I'm trying to compile externals on Windows 10 using mingw32 toolchain. Pd version 0.47.1
 
I always get link errors related to Pd's global symbols being undefined, e.g.
 
    undefined reference to `_imp__s_bang'
    undefined reference to `_imp__s_list'
 
etc
 
My linker flags are:  
 
   gcc  -shared -Wl,--enable-auto-import -o test.dll -L.../pd/bin -lpd
 
I get a similar issue linking externals built with Flext. Linkage seems to work fine except for these symbols.
 
Any ideas?
