Hi Christof,
I should add that I followed the steps given here:
https://lists.puredata.info/pipermail/pd-list/2007-06/051560.html
2007 is quite a long time ago. I have success with this description:
http://puredata.info/docs/developer/WindowsMinGW, but this is 32-bits.
Is there a special reason for compiling for 64-bits? I noticed 32-bits
excutables works ok on a 64-bits Windows. And all externals at deken are
32-bits...
However, "-export_dynamic" gave me:
C:\msys64\mingw32\bin\ld.exe: warning: cannot find entry symbol xport_dynamic;
defaulting to 10001000
trying "-E" and "--export-dynamic":
Some time ago the gmu compiler switched to '--export-dynamic' for this
option.
C:\msys64\mingw32\bin\ld.exe: warning: --export-dynamic is not supported for PE
targets, did you mean --export-all-symbols?
so I tried with "--export-all-symbols" and this worked for obj1.c and obj2.c. I
can't, however, see why it doesn't work for obj3.c as the difference to obj2.c is rather
marginal (adds an outlet and a state variable).
Any hints are greatly appreciated!
About the previous errors; make really dislikes spaces in paths. Try it
with paths without spaces.
Greetings & success,
Fred Jan

Betreff: [PD] Externals built with MSYS2/MinGW won't load
Dear list,
I tried to compile the test externals in doc/6.externs on Windows 7 from the
command line using MSYS2/MinGW.
I put everything (source files, m_pd.h and pd.dll) in one folder for the sake
of convenience.
I compile with
$ gcc -c obj1.c -o obj1.o
and link with
$ ld --export-all-symbols -shared -o test-obj3.dll obj3.o pd.dll
compiling and linking works without any errors or warnings.
test-obj1 and test-obj2 seem to load and work fine in Pd, but for test-obj3 Pd
console tells me:
"C:\\Program Files (x86)\\pd vanilla\\extra\\stuff\\test-obj3.dll: couldn't
load"
The same thing happens when I try to build test-obj4, test-obj5 and
test-dspobj~.
What could be the problem? I took the source files as they were and built all
objects the exact same way...
Many thanks in advance!
