Does anyone have any clear instructions on how to build a library using DevKitPro and Programmers notepad?

I've been looking around the web but all the answers that I can find to this question are one liners and are written as command lines. I'd like to read some sort of explanation of what needs to be done.

Thanks

Are you meaning to write your own "library" or cross-compile an existing one?

@Tantric - I have some fucnctions that I wrote and I want to put them in a library so that I can re-use them.

@lordzid - Does that go in the makefile somewhere? and will it give me a file with the 'a' extension that I can put in the libogc folder and reference from future projects?

-static is a linker flag. If you can't figure it out from there, perhaps you should pursue a career in the arts instead.

That is about the most unhelpful, rude comment I've seen on this forum; how about you help the guy instead of acting like a know-it-all jackass?

Anyway CurlyPaul, this post might be help to you:

Not having the intelligence to do your own research is counterproductive to programming, he needs to learn that now. Holding his hand will only get him hit by a car.

If I were CurlyPaul i'd be quite offended at your, frankly rude, evangelicalism.

Strange, I didn't need that flag, i just needed to add a makefile goal for the libX.a file that had the object files as it's dependency.

Are you invoking 'ar' or making shared lib instead?

Well thanks to all of you who tried to help (I'll check out the link later) and big fuck you to lordzid.

I did google it but like I said in op, all I found was a bunch of unhelpful elitist pricks talking in arguments rather than actually explaining anything.

Well, given the fact that it's kinda hard to use shared libraries on this particular platform, I can't have been using them.

You didn't say you weren't using ar.

adding the following line in your Makefile should (in theory, untested)work:

all:
powerpc-gekko-ar -rc "output.a" file1.o file2.o ...

@lordzid: it's a coding help forum, what is obvious for you may be not for others... oh btw, speaking about shared libraries and -static flag on the Wii could make you appears as quite ignorant yourself ;-)

according to gcc doc:

Quote

`-static'
Do not link against shared libraries. This is only meaningful on
platforms for which shared libraries are supported. The different
variants of this option are for compatibility with various
systems. You may use this option multiple times on the command
line: it affects library searching for `-l' options which follow
it. This option also implies `--unresolved-symbols=report-all'.
This option can be used with `-shared'. Doing so means that a
shared library is being created but that all of the library's
external references must be resolved by pulling in entries from
static libraries.

I would recommend against that make file, it will unconditionally rebuild the library file. Add the .a file as a dependency of "all" instead, that way make can do it's minimum update magic.
