Did you install cygwin on the target system or you naively tried to copy only DLL's you think are needed? -- With best regards, Andrey Repin Saturday, June 3, 2023 20:32:30 Sorry for my terrible english... -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

Indeed not. Rajesh, You should only ever send mail to the mailing list 'owner' address if you have a problem with your subscription to the mailing list. Therefore, it is probably never appropriate to send mail to both the list, and the owner of the list. Further, cygwin-develop...@cygwin.com is explicitly described as for "contributing to the development of Cygwin [...] If you have an issue and hope that someone will look into it for you then please do not send email here". That seems a clear request to not send this kind of mail there. By spamming all these addresses, you signal that you are impatient, inconsiderate and not respectful of the boundaries of others. This won't help you engage members of our community who are willing to help you solve your problem. Please don't do it ever again. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

127 is a POSIX return code meaning the binary file is not executable and cannot
be started.
Check what "ldd ./sample" shows. Most likely you are missing the required
runtime (dlls).
Especially check that the DLL dependencies including cygwin1.dll are all
installed in some .../bin/ directory which is at or near the start of your PATH,
and that any other file dependencies are also installed under the same upper
level Cygwin "ROOT" directory (the directory above the cygwin1.dll)!
What those file dependencies are will depend on what your program calls e.g.
$ ls -gloU /etc/{mtab,hosts,networks,protocols,services}
lrwxrwxrwx 1 12 Sep 1 2015 /etc/mtab -> /proc/mounts
lrwxrwxrwx 1 53 Sep 1 2015 /etc/hosts ->
../proc/cygdrive/c/Windows/System32/drivers/etc/hosts
lrwxrwxrwx 1 56 Sep 1 2015 /etc/networks ->
../proc/cygdrive/c/Windows/System32/drivers/etc/networks
lrwxrwxrwx 1 56 Sep 1 2015 /etc/protocols ->
../proc/cygdrive/c/Windows/System32/drivers/etc/protocol
lrwxrwxrwx 1 56 Sep 1 2015 /etc/services ->
../proc/cygdrive/c/Windows/System32/drivers/etc/services
also /etc/{fstab,fastab.d/,nsswitch}, /dev/{mqueue,shm},
/var/run/{cygfork/,utmp} and others.
Some may be set up by the initialization code, others by the Cygwin Setup
program, or postinstall scripts, and may need to be set up externally if the
Cygwin Setup program is not used, e.g. /home/, /tmp/, /usr/, /var/ if the
program calls functions which use those.

Getting return code "127" after execution of program
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.
