So, from that: the typeinfo is clearly in the original .o file, and it's a
public symbol in .rdata that really ought to be exported - if auto-export is
in operation.
The next step is to manually re-run the final link command that you posted
earlier:
g++ -shared -nostdlib /usr/lib/gcc/i686-pc-cygwin/4.3.2/crtbegin.o
.libs/libxerces-c.la.lnkscript -L/usr/lib /usr/lib/libcurl.dll.a
/usr/lib/libssh2.dll.a -lssl -lcrypto -lz -licuuc -licudata
-L/usr/lib/gcc/i686-pc-cygwin/4.3.2
-L/usr/lib/gcc/i686-pc-cygwin/4.3.2/../../..
/usr/lib/gcc/i686-pc-cygwin/4.3.2/libstdc++.dll.a -lgcc_s -lgcc_s
-lcygwin -luser32 -lkernel32 -ladvapi32 -lshell32 -lgcc_s -lgcc_s
/usr/lib/gcc/i686-pc-cygwin/4.3.2/crtend.o -o
.libs/cygxerces-c-3-0.dll -Wl,--enable-auto-image-base -Xlinker
--out-implib -Xlinker .libs/libxerces-c.dll.a
adding "-Wl,--enable-extra-pe-debug", which should show us a bit more about
what ld thinks it is doing when it decides whether or not to export all the
symbols.
cheers,
