Multiple missing dependencies/files despite following build instructions

[EmeraldTiger]

Hello!

I'm trying to build the netradiant-custom source and I'm running into a wall... I have followed the instructions for building on Windows using MSYS2:

Win32 (using MSYS2)(recommended)
==================

environment:
- MSYS2 (http://www.msys2.org/)
- from msys2_shell:
  pacman -S --needed base-devel
    32 bit:
  pacman -S --needed mingw-w64-i686-{toolchain,gtk2,gtkglext}
    64 bit:
  pacman -S mingw-w64-x86_64-{toolchain,gtk2,gtkglext}
    these are only strictly required for gamepacks:
  pacman -S --needed unzip svn git

build:
- Start respective mingw shell
- Switch to the directory with NetRadiant-custom source
- Typical release build:
  make MAKEFILE_CONF=msys2-Makefile.conf BUILD=release -j$(nproc)
- Typical developer's build:
  make MAKEFILE_CONF=msys2-Makefile.conf DEPENDENCIES_CHECK=off DOWNLOAD_GAMEPACKS=no INSTALL_DLLS=no BUILD=debug RADIANT_ABOUTMSG="NetRadiant custom dev build" -j$(nproc)
run:
- in the "install" directory, double click netradiant.exe

I installed MSYS2, ran all four pacman commands (I tried both 32 bit and 64 bit) and everything seems to work fine up until I try to build the makefile, then I get this:

$ make MAKEFILE_CONF=msys2-Makefile.conf BUILD=release -j$(nproc)

So it's saying I'm lacking certain files/dependencies, even though that was the whole point of the setting up the environment and running the pacman commands (or at least I thought), so it should have everything it needs after that. Has anyone else ran into this issue trying to build from source? I am very new to building other's codebases and I've pretty much always had problems trying to set up other people's code no matter how closely I follow the instructions. I'm using 64-bit Windows 10.

I think you are trying this from MSYS2 shell, which is intended for package management, gotta do from Mingw shell.
Can test utils presence on your own, for example by g++ -v
