Hey Guys, I'm having problems with installing Mongrel on Ubuntu 7.1 (Gutsy Gibbons). I installed the ruby dev library as per an earlier thread and that got me further along the way. The install completes with the following (long) message: ========================================================== Building native extensions. This could take a while... tst_search.c:3:19: error: stdio.h: No such file or directory tst_search.c:4:20: error: stdlib.h: No such file or directory tst_search.c:5:20: error: assert.h: No such file or directory tst_search.c: In function ¡Ætst_search¡Ç: tst_search.c:12: error: ¡ÆNULL¡Ç undeclared (first use in this function) tst_search.c:12: error: (Each undeclared identifier is reported only once tst_search.c:12: error: for each function it appears in.) make: *** [tst_search.o] Error 1 tst_search.c:3:19: error: stdio.h: No such file or directory tst_search.c:4:20: error: stdlib.h: No such file or directory tst_search.c:5:20: error: assert.h: No such file or directory tst_search.c: In function ¡Ætst_search¡Ç: tst_search.c:12: error: ¡ÆNULL¡Ç undeclared (first use in this function) tst_search.c:12: error: (Each undeclared identifier is reported only once tst_search.c:12: error: for each function it appears in.) make: *** [tst_search.o] Error 1 ruby extconf.rb install mongrel checking for main() in -lc... no creating Makefile make cc -I. -I. -I/usr/lib/ruby/1.8/i486-linux -I. -fPIC -fno-strict-aliasing -g -O2 -fPIC -c tst_search.c make install cc -I. -I. -I/usr/lib/ruby/1.8/i486-linux -I. -fPIC -fno-strict-aliasing -g -O2 -fPIC -c tst_search.c make clean Successfully installed mongrel-1.0.3 Installing ri documentation for mongrel-1.0.3... Installing RDoc documentation for mongrel-1.0.3... ======================================================================= So, the install appears to be successful despite the earlier error messages.... However, when I attempt to start up mongrel I get the following error: user@ubuntu710desktop:~/projects/tester$ mongrel_rails start -d /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- http11 (LoadError) from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.4/bin/../lib/mongrel.rb:8 from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:33:in `gem_original_require' from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:33:in `require' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.4/bin/mongrel_rails:11 from /usr/bin/mongrel_rails:18:in `load' from /usr/bin/mongrel_rails:18 Do I need to install other ruby packages as prerequisites? *Any* help would be really appreciated.
