You can install gcc by running setup-x86.exe or setup-x86_64.exe again. The gcc package is in the Devel category:

the instalation of GCC seemed to work fine, but when i run gcc -- version, i get greeted by "bash:gcc: command not found" response. i followed the instructions with every step. what could be the issue?
I found a fix thanks to chatgpt ( who would've thought). turns out the MSYS2 link from the vs code page was simply outdated, so i used this one from the MSYS2 page and ran the commands in the ucrt window. I will leave this here in hopes someone else finds and needs this

Not sure if this counts, since this is more about running code than writing it.
I have followed the instructions on these sites. I have also made sure to change "Path" in the environmental variables. https://code.visualstudio.com/docs/cpp/config-mingw https://www.mingw-w64.org/
The installation worked, but no matter what I try (running in command prompt, running in Visual Studio) I get something like: "'g++' is not recognized as an internal or external command, operable program or batch file." when I try to execute some code. Why is this?
EDIT 1: Visual Studio Code*, not Visual Studio.
EDIT 2: Seems to be working now! I'm the only user on my computer, but I had to change my system variables - not just the user variables - for it to work.
Hi,
I have installed gcc in Windows 11 environment, but I want to execute gtk, I searched the following link:
https://www.msys2.org/
I installed msys2-x86_64-2025221.exe
After that I tried the following command:
pacman -S mingw-w64-ucrt-x86_64-gcc
but finally gcc is not working please guide me.
The output is:
MSYS ~
$ pacman -S mingw-w64-ucrt-x86_64-gcc

$ gcc --version
-bash: gcc: command not foundHowever, gcc is already working on my computer on windows shell,
c:\msys64>gcc gcc: fatal error: no input files compilation terminated.
I want to install gtk.
Somebody please guide me.
Zulfi.
How do I go about compiling a simple c++ source file using my windows compiler?
I'm using ConEmu as a compiler.
I tried to compile a default key map and get the error message "sh: avr-gcc: comand not found".
When using make iris/rev2:default following error message appeared.
$ make iris/rev2:default QMK Firmware 0.6.246 Making iris/rev2 with keymap default /bin/sh: avr-gcc: command not found sh: avr-gcc: command not found sh: avr-gcc: command not found make[1]: *** [tmk_core/rules.mk:256: gccversion] Error 127 Make finished with errors make: *** [Makefile:544: iris/rev2:default] Error 1
I use windows10 and Msys2 64bit with "MSYS2 MinGW 64-bit".
I tried following to solve this error, but didn't solve the problem.
reinstall msys2 and qmk
rerun util/qmk_install.sh
run echo 'export PATH="/usr/local/opt/avr-gcc@7/bin:$PATH"' >> ~/.bash_profile and restart terminal
run pacman -S avr-gcc and "Error target not found: avr-gcc" appeared.
This is my first time of building key map, then I'm a beginner.
Any information would greatly help.
