OpenSSL ON WINDOWS!! - ld.exe cannot find -lcrypto/-leay32

Question

I am trying to build a C file using OpenSSL on (64-bit) Windows 7. I have downloaded the latest full binary from the official OpenSSL site, and am using MinGW, and have added the respective bin directories to PATH. However I am getting the following error :

c:\Workspace\OSAccess\c>gcc -I%JAVA_HOME%\include -I%JAVA_HOME%\include\win32 -Ic:\OpenSSL-Win64\include -std=c99 -lm -lcrypto -o libosaccess.dll osaccess.c
c:/mingw/bin/../lib/gcc/mingw32/4.8.1/../../../../mingw32/bin/ld.exe: cannot find -lcrypto
collect2.exe: error: ld returned 1 exit status

I cannot find any file called libcrypto.dll or cryptolib.dll, so I tried to build my own OpenSSL from source, using the install notes supplied, as I can see that the static libraries for crypto and ssl do not seem to be shipped with the Windows install. I have seen references in other posts to a couple of other libraries, libeay32 and ssleay32, but these return the same error.

If I remove the -lcrypto (or other) then I get Undefined reference errors:

Adding `-Lc:\OpenSSL-Win64 -leay32` was the solution for this. — MeanwhileInHell, Oct 16 '13 at 13:27
... and `-Lc:\Windows\System32 -lnetapi32` for the Netbios error — MeanwhileInHell, Oct 16 '13 at 15:46

If libcrypto.dll or cryptolib.dll are not there , i will recommend you to try and copy it from any other system . I had similar problem with , luckily found it on another system and copying worked well too.
