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?
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.

sorry, "/c/pdbinpath/pd.dll" is unix style (I use a msys2 shell). What I meant is: absolute path to pd.dll.

Hi Jamie, if you like to contribute a pull request to the flext build system, it would be appreciated! best, Thomas

according to one of the recent announcements of miller, the
"s_bang"-class of symbols (which is what your undefined references are
about), will go away in the near future.
you probably should update your code to use gensym("bang") rather than
s_bang (and probably do local caching of the variable).

Good :)
you probably should update your code to use
gensym("bang")rather thans_bang(and probably do local caching of the variable).
Thanks for the heads up.
but why? and wouldn't this break LOTS of existing code?

I'll keep s_bang, etc, alive in Pd vanilla, but if you want your extern to run in threadable versions of libpd in the future you should not use it. So nobody's patch will break as far as I know - this just limits ones ability to use old externs in, say, VST plug-ins powered by libpd.
