这是我第一次将程序构建到SNAP包中。我想让我的程序更容易访问。 构建没有问题。 但是libqtnetwor5看不到一些需要的库。在下面，您可以看到所有日志和配置的描述。

也许有人可以理解错误在哪里？或者也许有人可以告诉我如何更好地处理库（我的项目没有使用系统库） 最后一个问题，但并非最不重要的是，有人知道如何构建像这样的Qt项目吗？
答案 0 :(得分：0)
问题是你要从自己的版本和你的发行版（可能是Ubuntu）中混合Qt库。你正在构建的二进制文件取决于一个Qt库（你可以从你自己的Qt构建中获得），而这一个依赖于你从Ubuntu获得的另一个Qt库。所以这个问题的解决方案是只为Qt库使用一个源。
我可能会去分发库，除非有一些非常具体的原因使用你自己的。要这样做，您需要修复二进制编译（目前没有足够的详细信息），以便不与您的库（-I和-L标记，-rpath和类似的事情），其他一切都应该自动完成。
要打包自己的库，您需要使用-rpath标志构建它们，以便在库目录中也可以解析一个库的依赖关系。从我看来，snapcraft应该能够在这种情况下选择它们。
