ruby - Cannot start a new rails server - sqlite.3h is missing -


i trying run rails server on ruby on windows 7 operating system. made new rails application when try run server following error:

d:\projects\rubyonrails>rails server => booting webrick => rails 3.2.13 application starting in development on http://0.0.0.0:3000 => call -d detach => ctrl-c shutdown server exiting d:/ruby200-x64/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/rubygems_integration.rb:214:in `block in replace_gem': please install sqlite3 adapter: `gem install activerecord-sqlite3-adapter` (sqlite3 not part of  bundle. add gemfile.)

trying install activerecord-sqlite3-adapter:

d:\projects\rubyonrails>gem install activerecord-sqlite3-adapter error:  not find valid gem 'activerecord-sqlite3-adapter' (>= 0) in repository error:  possible alternatives: activerecord-jdbcsqlite3-adapter, activerecord-sqlserver-adapter, activerecord-bq-adapter, activerecord-simpledb-adapter, activerecord-mysql2-adapter

after try install sqlite3 gem following error (i had install devkit able proceed step):

d:\projects\rubyonrails>gem install sqlite3 temporarily enhancing path include devkit... building native extensions.  take while... error:  error installing sqlite3: error: failed build gem native extension.  d:/ruby200-x64/bin/ruby.exe extconf.rb checking sqlite3.h... no sqlite3.h missing. install sqlite3 http://www.sqlite.org/ first. *** extconf.rb failed *** not create makefile due reason, lack of necessary libraries and/or headers.  check mkmf.log file more details.  may need configuration options.

in system32 folder have sqlite3.dll, sqlite3.exe , sqlite export definition file.

also, sqlite3 seems working fine:

d:\projects\rubyonrails>sqlite3 sqlite version 3.7.16.2 2013-04-12 11:52:43 enter ".help" instructions enter sql statements terminated ";" sqlite>

also, bundle date:

d:\projects\rubyonrails>bundle check gemfile's dependencies satisfied

however in gemfile there no information version of sqlite3 gem , when put 1 server fails start:

source 'https://rubygems.org'  gem 'rails', '3.2.13'  # bundle edge rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git'  gem 'sqlite3'

please help!

you need install sqlite3-ruby gem instead of sqlite3 only

go http://www.sqlite.org, , download sqlitedll under "precompiled binaries windows". extract file , put 2 files sqlite3.dll , sqlite3.def in ruby bin's directory, i.e., c:\ruby\bin. run "gem install sqlite3-ruby" install sqlite3-ruby gem. (try "gem install --version 1.2.3 sqlite3-ruby" if latest version not working)

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'
