I tried following the steps posted but I get the following error when I run gem install sqlite3-ruby-1.2.1.gem charlesr@BRC_IT_OFFICER /cygdrive/t/~Charles/sqlite-3.3.16/bld $ gem install sqlite3-ruby-1.2.1.gem Building native extensions. This could take a while... ERROR: While executing gem ... (RuntimeError) Error instaling sqlite3-ruby-1.2.1.gem: ERROR: Failed to build gem native extension. ruby extconf.rb install sqlite3-ruby-1.2.1.gem checking for sqlite3.h... no make make: *** No rule to make target `ruby.h', needed by `sqlite3_api_wrap.o'. Stop . Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2. 1 for inspection. Results logged to /usr/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.1/ext/sqlite3_api /gem_make.out Does anyone know what the problem might be here? The only thing I did differently from the instructions was to use the Ruby package for Cygwin (ruby 1.8.5 (2006-12-25 patchlevel 12) [i386-cygwin]) Many thanks, Charles -- Posted via http://www.ruby-forum.com/.
