When I run

当我跑

rvm install 1.9.3 --with-gcc=clang

on Mac OSX Lion, ruby does not compile, and I get the following error in (.rvm/log/ruby-1.9.3-p374/make.log)

How can I get ruby 1.9.3 to install on Lion?

如何在Lion上安装ruby 1.9.3？

you are using clang, according to this ticket http://bugs.ruby-lang.org/issues/5883 - it's not "fully" supported - you need to try using gcc-4.2, you get instructions for homebrew with running rvm requirements.

你正在使用clang，根据这张票http://bugs.ruby-lang.org/issues/5883 - 它没有“完全”支持 - 你需要尝试使用gcc-4.2，你得到了自制的运行rvm要求的说明。

here is RVM ticket for this problem https://github.com/wayneeseguin/rvm/issues/1480

这是此问题的RVM票据https://github.com/wayneeseguin/rvm/issues/1480

UPDATE: Ruby-2.0.0 actually compiles better with clang then with gcc-4.2, more details here: https://*.com/a/15655034/497756

更新：Ruby-2.0.0实际上用clang然后用gcc-4.2编译得更好，更多细节在这里：https：//*.com/a/15655034/497756

With Xcode 4.6 I was also getting this problem. I installed the command line tools which made gcc available in /usr/bin/gcc.

使用Xcode 4.6我也遇到了这个问题。我安装了命令行工具，它们在/ usr / bin / gcc中提供了gcc。

I managed to get it to work using:

我设法让它使用：

rvm install 1.9.3 --with-gcc=gcc

NB. I dont have homebrew installed.

NB。我没有安装自制软件。

#3

If you don't have rvm already installed, rvm requirements won't work. Install gcc 4.2 with homebrew and restart the rvm installation. Worked for me.

如果您还没有安装rvm，则rvm要求将不起作用。使用自制软件安装gcc 4.2并重新启动rvm安装。为我工作。

brew update
brew tap homebrew/dupes
brew install apple-gcc42

#4

If you are using rbenv and ruby-build instead of rvm, you have to do this:

如果你使用rbenv和ruby-build而不是rvm，你必须这样做：

# this export must be done before every new ruby build
export CC=gcc
# use the version you wish to install
rbenv install 1.9.3-p385

If it doesn't work, you need to install gcc first:

如果它不起作用，您需要先安装gcc：

brew update
brew tap homebrew/dupes
# install apple-gcc, only once needed
brew install apple-gcc42
# Maybe you have to tell, which gcc version must be used,
# to get it working on newer systems
export CC=gcc-4.2

Until the ruby folks build a clang compatible ruby version, you have to export the CC variable before every build of a new ruby version

在ruby人员构建clang兼容的ruby版本之前，你必须在每次构建新的ruby版本之前导出CC变量

#5

I solved this using Macports.

我用Macports解决了这个问题。

I had problems compiling and were getting the error "Ruby 'ruby-1.9.3-p374' was built using clang - but it's not (fully) supported, expect errors."

我有编译问题，并且得到错误“Ruby'ruby-1.9.3-p374'是使用clang构建的 - 但它没有（完全）支持，期待错误。”

Github was also down for maintenance so I couldnt try compiling using brew as suggested in the previous answer... This is what I did, and it compiled fine on Mountain Lion 10.8.2:

Github也因为维护而失败，所以我不能尝试使用brew进行编译，如前面的答案所示......这就是我所做的，它在Mountain Lion 10.8.2上编译得很好：

First install Macports

首先安装Macports

http://www.macports.org/install.php

Then run:

然后运行：

sudo port selfupdate

sudo port install apple-gcc42

sudo port安装apple-gcc42

sudo rvm install ruby-1.9.3-p374 --with-gcc=gcc-apple-4.2

sudo rvm install ruby-1.9.3-p374 --with-gcc = gcc-apple-4.2
