请问Java的开发套件JDK8U341是否不支持Windows10了？

Posted 2023-05-07

右键jdk8安装文件的属性看到兼容性不包含Windows10，是不是就不支持了？

。。。。你这个问题，怎么回答呢。
Windows兼容模式是指在Windows中为程序提供了的兼容模式，是为了旧版的软件能在新框架内运行而设置的
这个和JDK无关。这个是windows的兼容模式。windows没有出window10的兼容，目前来说也不需要出，因为两个没区别。
建议学java之前先把计算机操作基础学明白追问

为什么双击jdk安装文件以后，不能安装jdk呢？

参考技术A 为什么win10不能安装Java？win10java的最新版本已下载多次，但无法安装。什么也做不了。请教我！ 参考技术B 为什么win10不能安装Java？win10java的最新版本已下载多次，但无法安装。什么也做不了。请教我！ 参考技术C 看上去是版本不对 你去http://www.***.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html 下一个windows 64位的jdk8安装 参考技术D 看上去是版本不对 你去http://www.***.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html 下一个windows 64位的jdk8安装

mingw64 的 gcc 不使用 mingw 套件的汇编程序

【中文标题】mingw64 的 gcc 不使用 mingw 套件的汇编程序

【英文标题】：gcc from mingw64 doesn't use assembler from mingw suite

【发布时间】：2018-10-14 04:27:36

【问题描述】：

我尝试使用 cygwin 下的 MinGW v6.4.0 进行编译。失败是因为i686-w64-mingw32-gcc 使用as 作为汇编编译器而不是i686-w64-mingw32-as。

根据详细输出：

汇编消息并不重要。失败是因为 x86_64 汇编器用于编译 x86 代码。

在日志消息中，我可以看到 gcc 是使用 --with-gnu-as 标志编译的。并且在构建过程中使用标准的as 命令。

那么，问题是：如何在构建过程中指定正确的汇编器 (i686-w64-mingw32-gcc)？

还有一个问题：这个来自 cygwin 或 mingw 的 bug 应该报告吗？

我尝试通过环境变量AS 指定汇编程序命令，但它不起作用。

我发现了类似的问题/讨论：

How to make gcc show the internal commands called? https://sourceforge.net/p/mingw-w64/discussion/723798/thread/ec84cb84

但他们没有给出任何可接受的答案。我不想重建 mingw 套件。

目前，我看到以下解决方法：创建一些临时目录并在那里添加符号链接 as，它指向 i686-w64-mingw32-gcc。然后我可以将选项 -Bprefix 传递给 gcc 以指定它查找二进制文件的位置。

是的。将-B/usr/i686-w64-mingw32/bin 选项添加到i686-w64-mingw32-gcc 有效。
