cygwin1.dll丢失-无法运行程序

Question

I wrote a program in C/C++ and compiled it using Cygwin. When I ran the compiled file, I receive an error about a missing library.

Answer 1

Cygwin is like a simple framework: With every program you build you have to include the library cygwin1.dll .

Important note : Downloading the library online might be risky as it can be a virus.

To fix the issue:
1. Go to your cygwin directory. Usually that is C:\\cygwin or C:\\cygwin64 . If you don't know where cygwin is, download the setup file and run it. The installation path the installer suggests is the Cygwin installation location.

Tip: Don't use a directory to put cygwin in that includes spaces (" ") as it will be easier to run programs with command-line parameters.

2. Copy the file. It should be in <Drive>:\\cygwin\\bin\\cygwin1.dll .

3. Copy the file to your program folder , the same directory as your exe file.

Your program should run without throwing an exception.
