我们正在尝试为Android构建PALISADE(https://git.njit.edu/palisade/PALISADE)。通过成功为Android构建“gmp”和“ntl”，我们取得了一些进展。
GMP可以立即进行交叉编译。 NTL有点棘手。我们使用了https://github.com/nemirst/ntl-android，但将 header 和src更改为PALISADE(10.5.0)中提供的版本
我们还对PALISADE makefile进行了一些更改，因此它们支持使用android独立工具链进行交叉编译。现在的问题是，当尝试使用交叉编译的NTL和GMP lib编译PALISADE时，出现以下错误:

我们非常感谢您为该库构建Android版。

最佳答案
这有点迟了，但如果您仍然感兴趣，则较新版本的Palisade不需要GMP或NTL(仅当用户在CMake构建过程中明确启用它们时才启用它们)，因此构建起来可能会更容易现在。您应该使用https://gitlab.com/palisade/palisade-release上的最新稳定版本，或者如果愿意尝试，可以使用https://gitlab.com/palisade/palisade-development上的开发版本。
交叉编译有些棘手，但是可以做到。我们正在开发一些嵌入式目标，但它们尚未发布。
我们正在考虑在将来的版本中支持Android端口，因此，您能与我们共享的任何进展都将受到赞赏。
