Ubuntu 16.04 上的 RedHawk 构建失败

Question

我正在尝试在 Ubuntu 16.04 上构建 RedHawkSdr CF。看起来这应该是一个相对简单的操作，但我不知道从哪里开始看这个问题。我相信我遵循了所有针对依赖项和环境变量的 Ubuntu 特定说明。

我收到此错误：

我按照说明下载了依赖项，但在更新存储库时发现了一个错误：

E: 获取失败 http://ppa.launchpad.net/redhawksdr/redhawk/ubuntu/dists/xenial/main/binary-amd64/Packages 404 未找到

E: 某些索引文件下载失败。他们被忽视了，或者老了 代替使用的。

我不确定这是否会导致任何问题。

看起来这是 expat 中的一个错误，这是一个 link，它为类似的错误提供了一些差异。

您需要应用相同类型的修复，在 elements.txx 第 282 行将 parser == 0 更改为 parser.get() == 0

这就是 expat 的 git repo 的当前 HEAD 的样子，他们有相同的修复

完成该修复后，框架应该可以编译。

关于 404 错误，该 ppa 中只有 Trusty (14.04) 的软件包。你可以看到here。在大多数情况下，16.04 的默认存储库中提供的 omniEvents 包应该可以正常工作。
