rubygems - "bundle install" for Ruby 1.8.7 on Ubuntu Raring Ringtail 13.04 -

-

i'm not rubyist , there might obvious i'm missing.

i've wrote application in ruby 1.8.7, i'm trying package in vagrant (running raring 13.04), i've run "bundle install" install requirements , though gem1.8 exist, running bundle install still install gems ruby 1.9.3. , program fails @ runtime...

any idea how solve this?

update 1

the related gemfile (thanks first answerers):

ruby '1.8.7'  # ... gem 'trollop'

but ruby1.8 myfile.rb error raised 

no such file load -- trollop (loaderror)

after investigation, problem looks in bundle install:

your ruby version 1.9.3, gemfile specified 1.8.7

i don't how solve problem.

update 2

after following advices @klaffenboeck things have changed. i'm using rvm , have ruby 1.8.7 when entering in project folder. bundler seems install things correctly, require seems fail... path problem?

see here detail vagrant / rvm setup: https://rvm.io/integration/vagrant

update 3

problem solved, missing a:

require 'rubygems'

before gems (it worked locally not in vagrant).

bundler install gems (by default) whichever ruby in path.

try /usr/bin/env ruby -v or which ruby figure out 1 is; guess you're running bundler ruby 1.8.

adding

ruby '1.8.7'

on top of gemfile diagnose.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
