c++ - Berkelium 编译错误

Question

这是我在 github ( https://github.com/sirikata/berkelium/issues/19) 上发布的 berkelium 项目问题的转贴。

我的问题:

在 Linux 上进行 Chromium 编译(Debian 测试，64 位，gcc 4.7.1，cmake 2.8.9)时，python 脚本 action_makenames.py 失败并出现以下错误:

...

Failed to install: chromium

看起来 python 脚本正在调用 perl 脚本，而 perl 脚本在第 209 行快要死了:

die "Unknown parameter $parameter for tags/attrs\n" if !defined($parameters{$parameter});

“未知参数”是:

• 数学
• 一个
• 接口(interface)名称
• 启动
• xmlns

我不确定这些参数是从哪里来的。

有人知道如何纠正这个问题吗？

原来是 gcc 4.6 的预处理器错误。作为修复，您必须删除 make_names.pl 中 gcc 预处理器命令的 -P 参数。
