That project's home page is @file{http://www.mingw.org/index.shtml}. +@subsection Can I build a Cygwin program that does not require cygwin1.dll at runtime? + +No. If your program uses the Cygwin API, then your executable cannot +run without cygwin1.dll. In particular, it is not possible to +statically link with a Cygwin library to obtain an independent, +self-contained executable. + +If this is an issue because you intend to distribute your Cygwin +application, then you had better read and understand +@file{http://cygwin.com/licensing.html}, which explains the licensing +options. Unless you purchase a special commercial license from +Red Hat, then your Cygwin application must conform to the GPL. + @subsection Can I link with both MSVCRT*.DLL and cygwin1.dll? No, you must use one or the other, they are mutually exclusive. |
