Hi, We are Trying to execute a program like ./sample.exe on 64 bit Cygwin. This executable is built with CMake on Cygwin 64 bit. The Program is not throwing any error or success details. it simply comes out from the running screen without any error and success states. and we checked output status using "*$?*" It returns "*127*" output. We checked the missing libraries by using "cygcheck sample.exe" and added the required libraries as per the *cygcheck* report. *Details:* $ gcc --version *gcc (GCC) 11.3.0* Copyright (C) 2021 Free Software Foundation, Inc.
