./cofigure --help ... --with-openssl[=DIR] build with OpenSSL support [/usr/local/ssl] so the right library is already detected. the function is called des_crypt and is completely compatible with std. i think that a AC_SEARCH_LIBS(crypto, des_crypt) in configure.in will suffice. then: #ifdef HAVE_DES_CRYPT #define crypt des_crypt #endif in the right file will do the trick.
