    Hi All !
    An older version (2003) of the compiler works ok.
    I do try compile of "nether earth remake" at new sdk-20160122 and sdk-20150619
    and i see :

    g++ -O3 -noixemul -c nether.cpp -o nether.o
    In file included from nether.cpp:15:
    list.h:68: `List' is not a template type
    list.h:68: redefinition of `struct List'
    /gg/os-include/exec/lists.h:24: previous definition here
    list.h:70: non-template type `List' used as a template
    list.h:70: ANSI C++ forbids declaration `' with no type
    list.h:70: abstract declarator `int ()()' used as declaration
    list.h:71: non-template type `List' used as a template
    list.h:71: confused by earlier errors, bailing out
    make: *** [nether.o] Error 1

    list.h :

    68 template <class T> class List {
    69 public:
    70 List<T>() {list=0;act=0;top=0;original=true;};
    71 ~List<T>() {
    72 if (original) {
    73 delete list;
    74 } /* if */
    75 };
    76 List<T>(List<T> &l) {list=l.list;act=list;top=l.top;original=false;};

    This is an include issue, and probably not a compiler issue, so I suppose you mean older version of the SDK...

    I'm guessing the problem is that some include (GL/SDL/?) is now including exec/lists.h containing struct List which directly conflicts with the List class in list.h.

    The easiest fix is probably to redefine List in list.h.

    Hi CISC !

    I tried different versions that I had and here's the result:
    SDK2.7 (20110916) - compile OK
    SDK3.2 (20130129) - compile OK
    SDK3.5 (20140508) & newer - compile error
    i did replace the list.h of any version - the result is the same (the same files).
    I had a break in programming at age 6, please tell me how "to redefine List in list.h."

    You have two choices: either rename your list class to something else (e.g. MyList) or let the preprocessor do it for you, by adding this line to the beginnig of your list.h:
    Code:
    #define List MyList

    If you choose the latter, make sure to include your list.h after the system headers, or you'll end up redefining List in the system headers too.
    This is just like television, only you can see much further.
