MSYS2_Configuration

My MSYS2 configuration. Installation, Proxy configuration. Useful commands.

MSYS2 is a minimalist linux/unix shell environment for Windows.

Install

Do all the steps listed here: http://msys2.github.io/
(troubleshooting guide here: https://github.com/msys2/msys2/wiki/MSYS2-installation )

Set-up Proxy

Most corporate networks require [proxy authentication] before connecting to the Net. You can probably skip this section on your home PC.

Edit .bash_profile

Go to your MSYS $HOME directory; in my case it's C:\msys32\home\alexander. Using a text editor, modify .bash_profile file as described below. Save it and then restart MSYS2 to apply the new settings.

#
# .bash_profile example
#
# Example proxy:
# export http_proxy=http://$USERNAME:$PASSWORD@proxy-server-name:1234
# Simpler example without username/password:
export http_proxy=http://PROXY_NETWORK:PORT

export https_proxy=$http_proxy
export HTTP_PROXY=$http_proxy
export HTTPS_PROXY=$http_proxy
export ftp_proxy=$http_proxy
export rsync_proxy=$http_proxy
export no_proxy="localhost,127.0.0.1,localaddress,.*.cnea.gob.ar,*redmine.ctrad.control*,*cnea.gov.ar,.local"

# export PATH

# git status on PS1 prompt
git_branch() {
     git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
export PS1="\[\e]0;\w\a\]\[\e[32m\]${HOSTNAME,,}:\[\e[33m\]\w\[\e[0m\]\[\033[35m\]\$(git_branch)\[\033[96m\]$\[\033[0m\] "

Add packages updates

pacman -Syu

Install gcc and g++ Compilers and dgb Debugger

As I am using a 64-bit operating system, I have opened the terminal for 64-bit.

pacman -Syu mingw-w64-x86_64-gcc
pacman -Syu mingw-w64-x86_64-gdb

If you are using a 32-bit operating system, you need to run the pacman -Syu mingw-w64-i686-gcc and pacman -S mingw-w64-i686-gdb commands in your MSY2 MinGW 32-bit terminal.

test if it is installed

g++ --version
gdb --version

Add the Directory to the Path of the Environment Variables

If you use a 64 -bit operating system like me, access the Mingw64 folder. In my case C:\msys64\mingw64\bin and copy the direction.

Open in windows Edit the system environment variables

• click Environment Variables from the Advanced tab.
• Click on the PATH and select it.
• Then click Edit.
• Click New. An empty field is displayed. Paste the directory here.

Using g++ and gdb with VScode

Select g++ compiler.

• Check or modify miDebuggerPath line in lauch.json file: "miDebuggerPath": "C:\\msys64\\mingw64\\bin\\gdb.exe".
• Check or modify command line in task.json file: "command": "C:\\msys64\\mingw64\\bin\\g++.exe"
