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, DaveK -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
