问题描述
由于奇怪的构建错误，我无法安装'iconv'gem。
我从源代码构建'libiconv'并将.h和.dylib链接到rvm的include和lib目录。
当我运行时
gem install iconv
Gem输出奇怪的构建错误：
构建本机扩展。这可能需要一段时间...
$ p $ 错误：安装iconv时出错：
错误：无法构建gem原生扩展。

Gem文件将保持安装状态/Users/myusername/.rvm/gems/ruby-1.9.2-rc2/gems/iconv-0.1进行检查。
结果记录到/Users/myusername/.rvm/gems/ruby-1.9.2-rc2/gems/iconv-0.1/ext/iconv/gem_make.out
如何安装并正确构建。
谢谢
我想我找到了原因！
看起来像Iconv gem还不符合1.9.x标准，所以它不会生成。
I fail to install the 'iconv' gem, because of weird build errors.
I have build the 'libiconv' from source and linked the .h and .dylib into the rvm's include and lib directory.When I run
gem install iconv
Gem outputs strange build errors:
Building native extensions. This could take a while...

How do I make it install and build properly.
Thanks
I think I have found out why !Looks like the Iconv gem is not yet 1.9.x compliant, so it will not build.
