MinGW-w64 offline installer

1. Install MSYS2

  • Download the installer for MSYS2 from its official website.
  • Run the installer and follow the on-screen instructions to install MSYS2 (usually in C:/msys64).

2.1 Download Individual Packages

If you’re preparing an offline repository: 1. On a system with internet access, use the pacman command to generate download links for all required packages: bash pacman -Sp --needed base base-devel mingw-w64-x86_64-toolchain > package_list.txt - This creates a file package_list.txt with URLs for all the required packages. 2. Download all the packages from the generated list and copy them to your offline_packages folder.

2.2 Copy Offline Packages

  • Insert the flash drive containing the offline_packages folder.
  • Copy the folder to a path accessible by MSYS2. For example: C:/msys64/home/BinhNN2/offline_packages
  • Ensure the path structure is correct and matches the instructions.

4. Recreate the Database Archive

Use the repo-add command to generate a valid offline.db: bash repo-add offline.db.tar.gz *.pkg.tar.* - Explanation: - repo-add: This command generates or updates a repository database file. - offline.db.tar.gz: This ensures the correct extension is used for the database archive. - *.pkg.tar.*: Matches all package files in the directory.

After running this command, you should see output indicating that the database file has been created and updated.

5. Edit pacman.conf

  • Open the MSYS2 configuration file for pacman using a text editor: C:/msys64/etc/pacman.conf

  • Locate and comment out the following repositories by adding a # at the beginning of their lines:

    # [mingw32]
# Include = /etc/pacman.d/mirrorlist.mingw32

# [mingw64]
# Include = /etc/pacman.d/mirrorlist.mingw64

# [msys]
# Include = /etc/pacman.d/mirrorlist.msys

  • Add a new repository definition for the offline packages at the bottom: [offline] SigLevel = Optional Server = file:///home/BinhNN2/offline_packages

  • Save and close the file.

6. Synchronize Pacman Database

  • Open an MSYS2 terminal (msys2.exe) and run: bash pacman -Syu
  • This synchronizes the package manager with your offline repository.

7. Install Required Packages

  • Install the required development tools and toolchain packages: bash pacman -S --needed base base-devel mingw-w64-x86_64-toolchain
  • Ensure the installation completes successfully.

8. Validation

  • Test the installation by running a simple command, such as checking the GCC version: bash gcc --version
  • If the version is displayed, the setup is complete.
