Troubleshooting - Some common compilation problems

1. If you get errors about "Crypt", add this to your compilation line (or to your Makefile):
   -lcrypt
   Example: gcc -lcrypt file.c

2. If you get errors about "Previous declaration of sys_errlist", you'll need to edit the file that is complaining (usually a .h file) and comment out the sys_errlist declaration. For example, with nuts333, you'll need to edit the "nuts333.h" file and comment out the line that says:
   
   extern char *sys_errlist[];
   You can comment it out by adding /* to the beginning and */ to the end:
   
   /* extern char *sys_errlist[]; */

   By default, programs are compiled with glibc (libc6). Certain codes aren't completely compatible with these libraries, so a version of libc5 is also installed on this system. If you are having trouble getting code compiled, try using "gcc5" instead of "gcc" for your compiler - this will compile it with libc5. If you have a Makefile, you can usually change the compiler in it, generally contained in the "CC" variable. (Note - tips #1 and #2 are glibc specific - if you have already tried those, make sure to undo the changes before trying to compile with gcc5)
