Hi. I''ve installed fcgi 2.4.0 on a CentOS 4.2 box without problems using: ./configure --prefix=/usr/local/fcgi --exec-prefix=/usr/local/fcgi make && make install When I try to install ruby-fcgi bindings I get the following: [root@machine ruby-fcgi-0.8.6]# ruby install.rb config -- --with-fcgi-lib=/usr/local/fcgi/lib --with-fcgi-include=/usr/local/fcgi/include install.rb: entering config phase... ---> lib <--- lib ---> ext ---> ext/fcgi /usr/bin/ruby /root/install/ruby-fcgi-0.8.6/ext/fcgi/extconf.rb --with-fcgi-lib=/usr/local/fcgi/lib --with-fcgi-include=/usr/local/fcgi/include checking for fcgiapp.h... yes checking for FCGX_Accept() in -lfcgi... no <--- ext/fcgi <--- ext install.rb: config done. So for some reason, the function FCGX_Accept() cannot be found. I get the same error if I try installing via gem. Anyone know what possibly can be wrong? Thanks. Morten
