Hello, I had been able to successfully compile Freeradius 3.0 Master branch from github up until 2012-07-04 with the following options, on Mac OS X 10.7. The last commit in the source code at that time was from 2012-06-29. ./configure \ --prefix=/usr/local/freeradius \ --mandir=/usr/local/share/man \ --libdir=/usr/local/lib/freeradius \ --includedir=/usr/local/include \ --without-rlm_perl \ --without-rlm_sql_mysql \ --with-rlm_pam \ --with-rlm_ldap \ --with-openldap-include-dir=/usr/include \ --without-rlm_counter \ --without-rlm_dbm \ --without-rlm_ippool \ --without-rlm_krb5 \ --without-rlm_otp \ --without-rlm_python \ --without-rlm_sql \ --without-rlm_unixodbc \ --without-rlm_sql_iodbc \ --without-rlm_sql_postgresql \ --without-rlm_sql_oracle \ --without-rlm_sqlcounter \ --without-rlm_sqlippool \ --without-rlm_eap_tnc \ --without-rlm_eap_ikev2 \ --with-udpfromto \ --disable-static \ --enable-shared \ --enable-strict-dependencies \ --enable-developer \ --enable-ltdl-install=yes \ The next time I attempted a build, on 2012-07-13, I ran into two issues: 1) ./configure keeps complaining of: configure: WARNING: unrecognized options: --without-rlm_perl, --without-rlm_sql_mysql, --with-rlm_pam, --with-rlm_ldap, --with-openldap-include-dir, --without-rlm_counter, --without-rlm_dbm, --without-rlm_ippool, --without-rlm_krb5, --without-rlm_otp, --without-rlm_python, --without-rlm_sql, --without-rlm_unixodbc, --without-rlm_sql_iodbc, --without-rlm_sql_postgresql, --without-rlm_sql_oracle, --without-rlm_sqlcounter, --without-rlm_sqlippool, --without-rlm_eap_tnc, --without-rlm_eap_ikev2, --enable-shared, --disable-static, --enable-ltdl-install 2) "make" eventually errors out: ...

Suspecting it might be related to the OS X 10.7 system-bundled openssl in /usr/ being decrepated by Apple (see http://ludovicrousseau.blogspot.com/2011/08/mac-os-x-lion-and-openssl.html), I tried specifying the following ./configure options to no avail (same outcome): --with-openssl-includes=/usr/local/include/openssl \ --with-openssl-libraries=/usr/local/ssl/lib \ I've also tried using various combinations of the following ./configure options instead, which caused "make" to fail with other errors (I could start separate threads about those later). --disable-ltdl-install \ --enable-ltdl-install=no \ --with-system-libtool \ --with-system-libltdl \ Looking at the commits between 6/29 and 7/13, I don't really see anything obvious (to me) that'd point to any change in how libltdl behaves. Between those two dates, I've updated GNU automake to 1.11.6 and my openssl (in /usr/local) from 0.9.8r to 1.0.1c. Any pointer on how to get the latest FR 3.0 Master branch to compile on my box would be much appreciated. Best Regards, Y.J. Zhang
