PHP IDE

Posted on by

A tak sobie z ciekawości sprawdziłem ile zasobów zajmą poszczególne edytory PHP. Wybrałem sobie 4: Eclipse, Netbeans, Textmate, Aptana, VIM.
Bardziej szczegółowo:

  • Eclipse Helios (Helios Service Release 2, build 20110218-0911)
  • Netbeans 7 (Build 201104080000)
  • Textmate (versja 1.5.10 (1631))
  • Aptana (versja 3, build: 3.0.5.201110061808)
  • VIM (versja 7.2.108)

w każdym edytorze został otwarty ten sam projekt ten sam plik do edycji, no może poza VIM gdzie otworzony został plik a nie projekt. I tak oto wyglądają zasoby mojego komputera.

VIM (2,9 MB) RAM
Textmate (46,5 MB) RAM
Eclipse (377,7 MB) RAM
Aptana 3 (389,3 MB) RAM
Netbeans (595 MB) RAM

To ja jednak zostanę przy Textmate :)

Rails 3.0.3 – mysql2 na OSX 10.6.8

Posted on by

Znowu ten sam problem, nowe Rails wymaga nowszego MySQL… odpalam Rails new project -d mysql no to super, potem baza rake db:create i …

rake aborted!
dlopen(/Users/wadziu/Sites/project/vendor/bundle/ruby/1.8/gems/mysql2-0.2.13/lib/mysql2/mysql2.bundle, 9): Library not loaded: /opt/local/lib/mysql5/mysql/libmysqlclient_r.16.dylib
  Referenced from: /Users/wadziu/Sites/project/vendor/bundle/ruby/1.8/gems/mysql2-0.2.13/lib/mysql2/mysql2.bundle
  Reason: Incompatible library version: mysql2.bundle requires version 17.0.0 or later, but libmysqlclient_r.16.dylib provides version 16.0.0 - /Users/wadziu/Sites/project/vendor/bundle/ruby/1.8/gems/mysql2-0.2.13/lib/mysql2/mysql2.bundle
/Users/wadziu/Sites/project/Rakefile:4
(See full trace by running task with --trace)

Rails 3.0.3 z wtyczką mysql2 wymagają min. libmysqlclient_r.17.dylib tak więc wypadałoby zainstalować nowszą wersję MySQL’a np.: versję 5.5.16 która ma libmysqlclient_r.18.dylib czyli wersję o +1 :)

no to ze strony http://dev.mysql.com/downloads pobieramy .dmg (oczywiście można pobrać źródła, skompilować etc. ale skoro jest paczka no korzystajmy z udogodnień). Instalacja click, click

MySQL

aliasy do .profile

alias mysql=/usr/local/mysql/bin/mysql
alias mysqladmin=/usr/local/mysql/bin/mysqladmin

no i przeładować 

. ~/.profile

odpalamy MySQL’a

sudo /Library/StartupItems/MySQLCOM/MySQLCOM start

i właściwie to wszystko, już można zrobić rake db:create, rake db:migrate

warto jeszcze przejrzeć README.txt dostarczony z paczką mysql-5.5.16-osx10.6-x86_64.dmg
