Hi.
I'm trying to create a shared library (under linux) and I not sure
what the
difference between the modifier *export* and the section *exports*
is? Or perhaps
when to use one and the other...
export means that you can control the name of a symbol in how it will
be in the elf file itself of the so.
So you call your original procedure Foo, but you export it as 'baz',
so using objdump in Linux, you'll find "baz" and not "Foo".
Exports, is the way to tell the compiler what are the symbols you wish
to make available for reuse in the so file itself, so I could bind to
them.
So in the following example "foo" would not be visible (neither as "foo"
nor "bar") to other program (eg. a C-program) unless I added an
*exports* section?
library test;
function foo(a: integer): integer; [export, alias: 'bar'];
begin
result := a * a;
end;
end.
Basically what i'm trying to do, is use a lot of units and I want avoid
creating a HUGE *exports* section but rather name the
methods in the units instead.
