global variables and class statics in a static library

[rsforster]

Does anyone know where I can get info on the rules for creating static
libraries in C++ (I am using Visual Studio 6.0)? Or can anyone answer
the following questions:

1. I have globals that are coming up as unresolved in the library test
application:

aule_timer * system_timer;
aule_keyboard * keyboard;

(I seem to have fixed this by specifying them in my main module in the
test app (instead of in the library module where I originally put them
- but an explanation of the rules for this kind of thing would be
useful)

2. I have two static class variables that are also coming up as
unresolved:

class aule_window_manager {
protected:

static aule_window_manager * application_window_manager;
static std::map<char *, aule_window_manager *> identifier_map; <-
this one
static std::map<HWND, aule_window_manager *> handle_map; <- and
this one

.... etc

Yes: in a group dedicated to your compiler/platform. See this FAQ for
what is on-topic here and for a list of other groups you might consider
(http://www.parashift.com/c++-faq-lite/how-to-post.html#faq-5.9).

Looks like spaghetti on the screen. I was refering to the two maps.
Both are static class variables.

Library implementations are outside the domain of the language and
this newsgroup. Try a newsgroup that discusses your compiler (see
my signature below).

Or can anyone answer the following questions:

Symbols are usually resolved in the latter phases of translation.
Commonly, this is in the linking phase. Perhaps you need to specify
a library or are specifying it incorrectly (e.g. in the wrong order).
Some tools will only parse a library once so the library must be
either later in the list or repeated in the list.

2. I have two static class variables that are also coming up as
unresolved:

class aule_window_manager {
protected:

static aule_window_manager * application_window_manager;
static std::map<char *, aule_window_manager *> identifier_map; <-
this one
static std::map<HWND, aule_window_manager *> handle_map; <- and
this one

Looks like the symbol "aule_window_manager" or "HWND" are not linked
in. Is there _code_ linked in for the symbols and not just the
{class} definitions?

Robin.
