I have a problem with freeRADIUS version 2.1.3. I have openssl installed in /usr/local/ssl. Tｏ build the freeRADIUS server, I used this command: ./configure --with-openssl-include=/usr/ｌｏｃａｌ／ｓｓｌ／ｉｎｃｌｕｄｅ−−ｗｉｔｈ−ｏｐｅｎｓｓｌ−ｌｉｂｒａｒｉｅｓ=/usr/local/ssl/lib However, the freeRADIUS just does not see the openssl and reports ｔｈｉｓ： 1. configure: skipping test for openssl/ssl.h  -- why skip? Because it was told? 2. ｃｈｅｃｋｉｎｇ　ｆｏｒ　ＯｐｅｎＳＳＬ　ｓｕｐｐｏｒｔ　．．．　ｎｏ What configuration did I miss such that the server did does not see the openssl? Thanks.
