无法安装/编译asciidoctor-数学gem

Question

在OSX上，根据说明，我已经安装了brew install glib gdk-pixbuf cairo pango cmake，安装了字体，甚至尝试了brew link gettext --force (但编译错误似乎与此无关…)

下面是发生的情况：

$ sudo gem install asciidoctor-mathematical
... output omitted
In file included from /usr/local/Cellar/glib/2.48.1/include/glib-2.0/glib/galloca.h:32:
/usr/local/Cellar/glib/2.48.1/include/glib-2.0/glib/gtypes.h:422:3: error: '_GStaticAssertCompileTimeAssertion_0' declared as an array with a negative size

我也在Ubuntu上尝试过：

$ sudo gem install asciidoctor-mathematical
... output omitted

             from /var/lib/gems/2.3.0/gems/mathematical-1.6.7/ext/mathematical/mtex2MML/src/../deps/uthash/uthash.h:29,
             from /var/lib/gems/2.3.0/gems/mathematical-1.6.7/ext/mathematical/mtex2MML/src/environment.h:4,

             from lasem_overrides.c:5:

超出了我的能力范围。我很乐意让它在这两个平台上工作。如有任何故障排除建议，欢迎光临。

我在Ubuntu 16.04上遇到了同样的问题，它通过以下命令进行了故障排除。

sudo MATHEMATICAL_SKIP_STRDUP=1 gem install mathematical
