Re: [Vala] why valac says "error: Failed to execute child process (Exec format error)"

[oyster <lepto python gmail com>]

Msys2 (msys2-x86_64-20160205.exe) has been installed, and I have used
$  pacman -Sy pacman
$  pacman -Syu
$  pacman -Su
which all say " there is nothing to do" now


I use this line to install Vala in msys2.exe
$  pacman -S mingw-w64-x86_64-vala

then
$ export LANG=en
$ export PATH=$PATH:/mingw64/bin

$ vala ./hello.vala
Compilation failed: 3 error(s), 0 warning(s)
error: Failed to execute child process (No such file or directory)
error: Failed to execute child process (No such file or directory)
error: Failed to execute child process (No such file or directory)

however, "hello.vala.c" has been created
