Hi. I've installed fcgi 2.4.0 on a CentOS 4.2 box without problems using: [root@machine fcgi-2.4.0]# ./configure --prefix=/usr --exec-prefix=/usr && 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/lib/ --with-fcgi-include=/usr/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/lib/ --with-fcgi-include=/usr/include/ checking for fcgiapp.h... yes checking for FCGX_Accept() in -lfcgi... no <--- ext/fcgi <--- ext install.rb: config done. For some reason, the ruby-fcgi picks up the header file alright, but not the lib dir. Any hints on why are greatly appreciated as I'm quite stuck here. Br, Morten
