为什么赛尔没有建立在我的Debian的基础上？

Question

我想更新到rails 3.2，但是therubyracer (0.9.9)的构建过程失败了。我不知道该怎么做。

我的环境: Debian挤压(2.6.32-5-AMD 64)

更新

我试过以下几种方法：

1. 下载了源git clone https://github.com/cowboyd/therubyracer.git的副本
2. 将$CPPFLAGS += " -fPIC"添加到ext/v8/extconf.rb
3. 用gem build therubyracer.gemspec构建gem
4. 用gem install therubyracer-0.9.9.gem安装gem

我也看到了同样的错误！发行：https://github.com/cowboyd/therubyracer/issues/135

Answer 1

一种解决方案是将0.9.8版作为0.9.9版运行。(解决不了真正的问题)：

1. 克隆热赛车源git clone https://github.com/cowboyd/therubyracer.git
2. 签出标签v0.9.8 git checkout v0.9.8
3. 将./lib/v8/version.rb中的版本号更改为0.9.9
4. 构建gem gem build therubyracer.gemspec
5. 安装gem gem install therubyracer-0.9.9.gem

Answer 2

在debian (带有amd64内核的686)上，我不得不卸载livb8，下载gem并为我的体系结构重新编译

gem uninstall libv8
wget http://rubygems.org/downloads/libv8-3.3.10.4.gem
ARCHFLAG='-arch i386' gem install ./libv8-3.3.10.4.gem
ARCHFLAG='-arch i386' gem install therubyracer

然后，热赛车(0.10.1)安装良好。

Answer 3

recompile with -fPIC

您是否尝试过添加-fPIC作为附加的生成标志？您可以在一个创业板安装中测试它：

$ gem install therubyracer -- -fPIC

或者，用邦德勒：

$ bundle config build.therubyracer -fPIC

看起来好像是别人在问题中指出了这一点。如果上面的内容不起作用，您可能会想要检查一下。
