Compiling openssl with ruby on windows

Question

Hello, i am trying to compile openssl with my ruby config on a windows computer with MingW. I am running ruby 1.9.2rc2 with these commands:

$ ruby extconf.rb --with-openssl-dir=/c/openssl
...
...
...
=== Checking done. ===
creating extconf.h
creating Makefile
Done.

Okay, so that works without any errors. Let's try to make:

$ make
gcc -I. -Ic:/Ruby192/include/ruby-1.9.1/i386-mingw32 -I/c/Ruby192/include/ruby-1
.9.1/ruby/backward -I/c/Ruby192/include/ruby-1.9.1 -I. -DRUBY_EXTCONF_H=\"extcon
f.h\" -Ic:/openssl/include    -O3 -g -Wall -Wno-unused-parameter -Wno-parenthese
s -Wpointer-arith -Wwrite-strings -Wno-long-long  -o openssl_missing.o -c openss
l_missing.c
In file included from openssl_missing.c:22:
openssl_missing.h:71: error: conflicting types for 'HMAC_CTX_copy'
c:/openssl/include/openssl/hmac.h:102: error: previous declaration of 'HMAC_CTX_

c:/openssl/include/openssl/evp.h:459: error: previous declaration of 'EVP_CIPHER

make: *** [openssl_missing.o] Error 1

And here i get some errors. I do see what the error is saying but i cant understand it or solve it.

Thanks for all the help i can get.

Hello,

Can I ask you why are you trying to compile the openssl extension?

It is part of Ruby itself, and using the right OpenSSL version it should compile properly.

Hint from the directories you're working, seems you're using RubyInstaller based installers, or maybe trying to work from scratch?

If is from scratch, I would suggest you look into RubyInstaller project which provides a repository of compilation recipes located on GitHub:

Hope that helps.
