When pacman ask for default selection=All, hit Enter and next step you should say 'Y' to start download. This can take a while, fast internet connection preferred ! After download pacman will install all packages automatically.
| Note |
|---|
| Every time you need a 'make' command you need to run the mingw version of make, which is `mingw32-make` To make this easier, you can execute this once: | Code Block |
|---|
| echo "alias make=mingw32-make" >> ~/.bashrc && . ~/.bashrc |
and just use 'make'. |
