Question

我在Debian 7下通过rbenv使用ruby 1.9.3p392，我试图安装qtbindings gem，这样我就可以运行一个使用qt libs的旧ruby应用程序。

以下是我在输入＆＃39; gem install qtbindings＆＃39;

时遇到的错误

我已安装以下要求

sudo aptitude install cmake build-essential bison openssl libreadline5 libreadline-dev curl git-core zlib1g zlib1g-dev libssl-dev vim libsqlite3-0 libsqlite3-dev sqlite3 libreadline5-dev libreadline6-dev libxml2-dev git-core subversion autoconf xorg-dev libgl1-mesa-dev libglu1-mesa-dev qtcreator

如何用fPIC编译ruby？我也试过了宝石安装qtbindings - -fPIC＆＃39;但得到了同样的错误。

Answer 1

尝试

#gem install qtbindings -- --with-cflags=\"-fPIC\"

来源： Is there any way to change gcc compilation options for a gem?

<强>编辑：

是的，再看看你的代码，我的错。问题在于安装的红宝石，而不是宝石。

查看this（上一篇文章）

尝试使用共享库重新安装ruby：

CONFIGURE_OPTS="--enable-shared" rbenv install 1.9.3-p392

ruby用fPIC编译
