Опитвам се да инсталирам mysql2
gem за Ruby 2.0.0.
Опитах да следвам инструкциите на http://rorguide.blogspot.hk/2011/03/installing-mysql2-gem-on-ruby-192-and.html, но не беше успешно. Предвид съобщението за грешка по-долу, може ли някой да ми помогне да разреша тази грешка?

Разгледайте тази статия: blog.mmediasys.com/2011/07/07/ и това: stackoverflow.com/a/5368767/117298 - person Luis Lavena   schedule 30.04.2013Стъпка 1 Инсталирайте Eclipse
Ако Eclipse все още не е инсталиран на машината, вземете най-новата версия на Eclipse IDE за C/C++ разработчици от страницата за изтегляне на Eclipse (http://www.eclipse.org/downloads/).
Ако Eclipse вече е инсталиран, но само за Java, изтеглете приставката C++, като следвате тези инструкции.
а. Отворете Eclipse и щракнете върху Help-›Install New Software
b. В полето Работа с: въведете http://download.eclipse.org/tools/cdt/releases/kepler. След няколко минути полето Име ще се попълни. Изберете следните компоненти:
° С. Щракнете върху Напред, съгласете се с твърденията и след това Край.
Стъпка 2 Изтеглете Cygwin
Инсталирайте Cygwin, като щракнете върху връзката setup-x86_64.exe на страницата за инсталиране на Cygwin (http://www.cygwin.com/install.html). След стартиране щракнете върху Напред през настройките по подразбиране, докато стигнете до прозореца Избор на пакети.
Ще трябва да потърсите и инсталирате два пакета: gcc и make.
Първият термин за търсене е gcc. Потърсете gcc и след това отворете папката Devel. Маркирайте следните пакети за инсталиране, като щракнете върху думата Skip (след това ще се промени на номера на компилация, който може да е по-висок от този, изобразен тук): gcc-core, gcc-g++ и libgcc1.
Вторият термин за търсене е make. Тук ще ни трябва само марката на пакета Devel.
След като ги изберете, щракнете върху Напред, за да инсталирате.
Стъпка 3 Изтеглете и създайте Google Test project
Изтеглете последната версия на GoogleTest от https://code.google.com/p/googletest/downloads/list и извлечете съдържанието на zip файла в обща директория. Важно е всички потребители да имат достъп до тази директория.
(Забележка: следните команди използват
make
-- последната версия на GoogleTest, която използваmake
, е https://github.com/google/googletest/releases/tag/release-1.8.1. За бъдещи ревизии на GoogleTest използвайтеcmake
вместо това.)За да изградите проекта Google Test:
cd c:/<<yourpath>>/gtest-1.7.0/make/
make
ar -rv libgtest.a gtest-all.o
Стъпка 4 Добавете директорията Cygwin bin към променливата PATH на компютрите
Следвайте инструкциите на тази страница за вашата версия на Windows: http://www.java.com/en/download/help/path.xml, за да добавите директория bin на Cygwins към променливата на средата PATH на компютрите. (обикновено чрез добавяне на ;C:\cygwin64\bin в края на текущата стойност).
Стъпка 5 Създайте нов проект, който използва GoogleTest
Стартирайте Eclipse и изберете File-›New-›C++ Project. Въведете стойностите по-долу и щракнете върху Готово.
В Project Explore щракнете с десния бутон върху името на проекта и изберете Properties. Под C/C++ Build променете типа Builder на Internal Builder.
Под C/C++ Build изберете Settings, след което щракнете върху папката Includes под Cygwin C++ Compiler. Щракнете върху бутона Добавяне в горното поле и след това прегледайте папката за включване на GoogleTest.
И накрая, под папката Cygwin C++ Linker изберете Miscellaneous и след това щракнете върху иконата Add под Други обекти. Намерете файла libgtest.a, който създадохте обратно в стъпка 3 (трябва да е в директорията make на разархивираната папка gtest).
Това е! Сега сте готови да го изпробвате.
Стъпка 6 Напишете код, който използва GoogleTest
Копирайте и поставете кода по-долу в съответните файлове:
Counter.h
Counter.cpp
Counter_Tests.cpp
В менюто Project изберете Build All. Сега, за да свържете рамката за тестване на единица на GoogleTest, изберете Изпълнение на конфигурации от менюто Изпълнение. От този диалогов прозорец изберете C/C++ Unit и щракнете върху бутона New.
Трябва да попълни това име на проекта автоматично под C/C++ Application, ако не, щракнете върху Search Project, за да изберете този проект. След това щракнете върху раздела C/C++ Testing. В падащото меню Tests Runner изберете Google Tests Runner и след това щракнете върху Run, за да гледате магията!
По-долу е моментна снимка на резултата. След като напишете още код/тестове, можете да щракнете върху бутона, маркиран в червено, за бързо прекомпилиране и повторно изпълнение на всички тестове.
