Arch Linux User Repository

I just fixed all these problems. Not sure how it was compiling before.

I created the following ticket upstream: https://sourceforge.net/p/ninvaders/bugs/2/

I am also hosting a fork here so that you can play it immediately! https://sourceforge.net/p/ninvaders0/code/ref/main/

Hello. Not compiling

Just tried to install; got lots of "multiple definition" errors:

"ufo.o:(.bss+0x6d0): multiple definition of aliens; aliens.o:(.bss+0x6d0): first defined here" etc.

Had to install ncurses-full to resolve issue with tinfo: /usr/lib/libtinfo.so.6: error adding symbols: DSO missing from command line So maybe add that as a dependency, unless there's a better way to fix it. Another issue while playing is that Shields aren't being drawn correctly (weirdly misaligned), not sure if related to previous issue.

ninvaders: error while loading shared libraries: libncursesw.so.5: cannot open shared object file: No such file or directory I think Arch switched to ncurses version 6.
