Hello! I try it. By manual from http://wiki.freeradius.org/building/Build#Building-Debian-packages I did these steps: I'm install firebird-dev package. Result of command "sudo dpkg -L firebird-dev" /. /usr /usr/lib /usr/lib/i386-linux-gnu /usr/share /usr/share/doc /usr/include /usr/include/perf.h /usr/include/ibase.h /usr/include/iberror.h /usr/include/ib_util.h /usr/lib/i386-linux-gnu/libfbembed.so /usr/lib/i386-linux-gnu/libfbclient.so /usr/share/doc/firebird-dev then I fix debian/rules file in this part (added strings with word "firebird"): ./configure $(confflags) \ --prefix=/usr \ --exec-prefix=/usr \ --mandir=$(mandir) \ --sysconfdir=/etc \ --libdir=$(libdir) \ --datadir=/usr/share \ --localstatedir=/var \ --with-raddbdir=$(raddbdir) \ --with-logdir=/var/log/$(package) \ --enable-ltdl-install=no --enable-strict-dependencies \ --with-large-files --with-udpfromto --with-edir \ --enable-developer \ --config-cache \ --without-rlm_eap_tnc \ --with-rlm_sql_postgresql_lib_dir=`pg_config --libdir` \ --with-rlm_sql_postgresql_include_dir=`pg_config --includedir` \ --with-rlm_sql_firebird \ --with-rlm_sql_firebird_lib_dir=`/usr/lib/i386-linux-gnu/` \ --with-rlm_sql_firebird_include_dir=`/usr/include/` \ --without-rlm_eap_ikev2 \ --without-rlm_sql_oracle \ --without-rlm_sql_unixodbc \ --with-system-libtool \ --with-system-libltdl But, firebird deb is absent, although other packages, such as mysql, postgresql is present. Why? Please tell me, where is my error? I would be very grateful for any help!
