Hi, 芦翔 please check, if you are using the right include path fpr the right .h files. After calling this:
C:\From_Here\openssl.1.0.0\> perl Configure VC-WIN32 no-asm --prefix=c:/to_here/ssl C:\From_Here\openssl.1.0.0\> ms\do_ms you DON'T should use: -I C:\From_Here\openssl.1.0.0\include (or "Additional Include directories" in VS GUI). It's because the .h files there all consisting of incomplete files, just containing the line "Link: filename.h". Instead, look into \ (root directory), there is some new directory tree /usr/bin/to_here/ssl (or similiar, I don't remember the exact location). So better use -I /usr/bin/to_here/ssl (or whatever exact to_here location is). Same for *.LIB (Additional Linker Dependencies) If this helps, please report. Otherwise also.
