I installed the mingw stuff from yaourt on arch linux but when i type
x86_64-w64-mingw32-gcc tom.c ncurses_functions.c terminal_functions.c list_functions.c -o -lpdcurses tom_windows.exe
I get:
x86_64-w64-mingw32-gcc: error: tom_windows.exe: No such file or directory
It must be something simple but I don't know what!
Try:
x86_64-w64-mingw32-gcc tom.c ncurses_functions.c terminal_functions.c list_functions.c -o tom_windows.exe -lpdcurses
The argument after -o is the output filename. In your case, you've told it to output to a file called -lpdcurses. Then you've told it to compile tom_windows.exe (as if it was a source file).
Swap the order of -o and -lpdcurses.
