JNA加载.a/.lib库
我正在尝试为 libfaad2 编写 jna 映射。 该库使用 mp4ff 来解析 mp4 文件。 mp4ff 在 Windows 上编译为 libmp4ff.lib，在 Linux 上编译为 libmp4ff.a。 JNA 仅查找 .dll/.so 文件。 那么如何将这个mp4ff加载到jna中呢？

我认为这个问题有答案。 我讨厌 AAC，我花了 4 天时间用 ffmpeg 调试无效的内存访问，现在 libfaad 使用了一些奇怪的库。 :(
i'm trying to write jna mapping for libfaad2. The library uses mp4ff for parsing mp4 files. mp4ff is compiled into libmp4ff.lib on windows and libmp4ff.a on linux. JNA only looks for .dll/.so files. So how can I load this mp4ff into jna?
EDIT
I think this question has the answer. I hate AAC, I've spent 4 days debugging invalid memory access with ffmpeg, now libfaad uses some weird libraries. :(

我认为您是对的，this 中的答案与此处相关。 在 UNIX 类型的系统上，
.a文件是一种特殊类型的存档，包含只能静态链接到应用程序的库（听起来像.lib文件）在 Windows 上也是一样的）。 这意味着无法在运行时加载该库，因为您将需要动态库。 但请注意，这不是 JNA 的限制，而是大多数操作系统工作方式的一般限制。静态库成为生成的可执行文件（或库）的“一部分”，而动态库可以在运行时加载。 每种方法都有优点和缺点（例如，静态库通过不依赖现有的正确版本的其他库使应用程序更加自给自足，但动态库可以节省磁盘和内存空间以及单个库）文件以更新（如果有安全补丁或其他错误修复补丁）。 我见过的大多数软件都可以编译为静态或动态（共享）库，因此如果您无法在某处找到所需的内容（或自己编译），我会感到惊讶。
I think that you are right that the answer in this is relevant here. On UNIX-type systems,
.afiles are a special type of archive, holding a library that can only be statically linked into an application (it sounds like a.libfile is the same thing on Windows). That means that there is no way to load that library at runtime, as you will need a dynamic library. But know that this isn't a limitation of JNA, it is a general limitation of how most operating systems work.Static libraries become "part" of a resulting executable (or library) whereas dynamic libraries can be loaded at runtime. There are advantages and disadvantages of each (for example, static libraries make an application more self-sufficient by not relying on other libraries being present and in the correct versions, but dynamic libraries can save both space on disk and memory as well as a single file to update if there are security or other bugfix patches). Most software that I have seen can be compiled to both a static or dynamic (shared) library, so I would be surprised if you couldn't find what you are looking for somewhere (or compile it yourself).
