By not explicitly telling ld what to export, you are implicitly telling it to export-all symbols from all your objects and archives, excluding a few system libs. Tell ld to exclude tclstub84.lib from exports, as well
$ gcc -v -shared -mno-cygwin \ -o libTclMagick.dll \ -L'/cygdrive/c/Program Files/ImageMagick' \ TclMagick.o \ -ltclstub84 \ -lCORE_RL_wand_ -lCORE_RL_magick_ \ -Wl,--exclude-libs,tclstub84.lib
That did it. Thanks much.
Where can I learn about this "export" stuff? I've never, ever had to "export" anything (via ld) when making a .so on unix -- it's all done
(for C) by *not* declaring a symbol as "static". Any suggestion on
a tutorial that explains the how and why when linking dll's on
windows?
