haskell'openid'包取决于需要openssl的HsOpenSSL和nano-hmac包。我已经在C:\ OpenSSL \目录中为MinGW编译了openssl,并使用以下命令安装了openid包:
cabal install openid --extra-include-dirs=C:\OpenSSL\outinc --extra-lib-dirs=C:\OpenSSL\out
当我尝试使用这个软件包编译haskell程序时,我收到很多链接错误。
test.hs:
import Network.OpenID
main = print "ok"
ghc --make test.hs
:

我做错了什么?
答案 0 :(得分:1)
我怀疑某处可能存在版本不匹配。尝试在这里使用OpenSSL的预编译二进制文件:http://www.openssl.org/related/binaries.html
我能够在这里获得使用最新版HsOpenSSL的说明:http://hackage.haskell.org/trac/ghc/wiki/Builder(实际上我与维护者合作,使这些说明无需修补包。)
