The answer is:
>put value.o in lib*.so.*
What I found out was that you really dont need lib*.sa.*, just only lib*.so.*.
Solaris 2.0 does not require lib*.sa.*. And since we will be going to
Solaries 2.0 soon, this works out fine.

A while ago, I asked the question:
--------------
>Hello Sunmanager,

>test_app was built as: acc -o test_app test_app.o -lfoo_lib...
>ld.so: call to undefined procedure _foo from 0xf776306c.

But since the question was vague and most of the answers I've got
was different from everybody else. So I resubmited a more detailed
question to those that replied:
--------------
| Thank you for all your responses. I guess that I owe you guys
| an apology for not elaborating the problems I was asking.
|
| So please let me elaborate it a little bit. I have three simple files:
|
| main.c - Set a value defined in static library(libvalue.sa.1.1)
| set_it.c - Shared function, defined in libvalue.so.1.1
| value.c - Just a file which defines a global variable(int value)
|
| The built was successfull, but when I try to run, "main", I got:
|
| ld.so: Undefined symbol: _value
| ---------------------------------------------------------
|
| file: main.c Built as:
| acc -Xc -c main.c
| acc -o main main.o -L. -lvalue
|
| -------------------
| main()
| {
| set_it(2);
| get_set_value();
| }
| --------------------
|
| file: set_it.c Built as:
| acc -Xc -c -pic set_it.c
| ld -o libvalue.so.1.1 -assert pure-text set_it.o
| --------------------
| #include <stdio.h>
| extern int value;
|
| set_it (int i)
| {
| print ("set_it %d\n", i);
| value = i;
| }
|
| get_set_value(void)
| {
| printf ("get_set_value %d\n", value);
| }
| ---------------------
|
| file: value.c Built as:
| acc -Xc -c -pic value.c
| ar cq libvalue.sa.1.1 value.o
| ranlib libvalue.sa.1.1
| ---------------------
| int value;
| ---------------------
|
|
| Thank you very much for your help.

And here is the answer:

> The lib*.sa.* part should contain all functions/data that you
> want to be statically linked. (In fact, it should contain all
> exported initialised data of a library). Those functions and data
