【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 我正在运行一个程序，想查看它的返回代码是什么（因为它会根据不同的错误返回不同的代码）。 我知道在Bash中，我可以通过运行 回声$？ 在Windows上使用cmd.exe怎么办？ #1楼 测试 ErrorLevel 适用于 控制台 应用程序，但是 dmihailescu 暗示，如果您试图从命令提示符下运行 窗口化 应用程序（例如基于Win32的 窗口） ，则此方法将无效。 一个窗口化的应用程序将在后台运行，并且控件将立即返回到命令提示符（最有可能的 ErrorLevel 为零，以指示该进程已成功 创建 ）。 当窗口应用程序最终退出时，其退出状态将丢失。 但是，与其使用其他地方提到的基于控制台的C ++启动器，一种更简单的选择是使用命令提示符下的 START /WAIT 命令来启动窗口应用程序。 这将启动带窗口的应用程序，等待其退出，然后将控制权返回到命令提示符，并在 ErrorLevel 中设置进程的退出状态。 start /wait something.exe echo %errorlevel% #2楼 如果要完全匹配错误代码（例如等于0），请使用以下代码： @echo off my_nify_exe.exe if %ERRORLEVEL% EQU 0 ( echo Success ) else ( echo

How to compile existing posix code for 64-bit Windows?

由 耗尽温柔 提交于 2019-12-20 15:46:28
问题 I'm ok with using Cygwin or MinGW, but I need to end up with 64-bit code, not 32-bit. This is because I will be calling the DLL from 64-bit managed C#. I can't seem to find and good references for setting up those tools to create 64-bit binaries. Also, it would be nice if the GCC was version 4, not version 3 as came with my Cygwin install. An alternative would be some form of interprocess communication. I will research that, but what I laid out above is what I really want. 回答1: The 64-bit

问题 How can I execute a.exe using the Cygwin shell? I created a C file in Eclipse on Windows and then used Cygwin to navigate to the directory.

问题 Cygwin - How would I find the Cygwin's version which has been installed on my machine? (Win Vista) 回答1: With the uname utility, as on other POSIX systems. uname -r 回答2: If you want to detect if you're running the 32 bit or 64 bit version, the -m switch will tell you: uname -m "i686" for the 32-bit version, "x86_64" if it's 64-bit. uname -a ..gives you all the information at once. Check man uname for details. (This is also answered in How do I tell whether my cygwin installation is 32 or 64
