gdb doesn't print the output on the terminal

gdb doesn't print the output on the terminal

[Gaetano Buldo]

Hello,
I installed Cygwin for 64bit window, and the following tools in order to
build and debug c programs using eclipse.
gcc 9.3.0-2
make 4.3-1
gdb 9.2-1
It seems like the gdb program doesn't print on the terminal.
When i run gdb --version a get an empty string on the terminal
When i run gdb, i can see the programm running on the task manager, and i
can quit it writing 'q' (even if the string doesn't appear on the terminal).
gcc and make works fine. When i check the version i normally get the
expected output, and i'm also capable to build a C project.
Any suggestion?
Thanks,
Gaetano

this usually means you are missing some libraries or you have an 
incorrect version of oune of them

These commands can help to identify the issue

$ cygcheck /usr/bin/gdb

$ strace -o /tmp/gdb.strace /usr/bin/gdb --version

the strace shows a normal exit.

What terminal are you using ?

I used cygwin64 terminal (C:\cygwin64\bin\mintty.exe) to generate these
files.
I tried gdb on both  cygwin64 terminal and window command prompt.
I don't get any output on both of them
