how to develop library ( .a and .so files) ! URGENT!!!

[zoltan]

Hi all,
This is REALLY urgent. I need some pointers/ links/suggestions on
how to develop a library using C. The library needs to be made generic
afterwards by using C++. Any ideas? The target is to develop a library
to implement a DNS Query, so I guess it should be a file in .a or .so
format. Any help will be greatly appreciated. Really urgent. Googling
didn't help at all. Thanks a lot...

Regards,

Timmy Jose.

Write functions in a C file then compile the file using -shared
if you use gcc. The result is a dll (.so).
The question is OT on c.l.c.

Hi Nelu,
Sorry if the topic was out of place.... But thanks a lot anyway.
That helped a lot... I guess I'll "man" gcc and get the whole
documentation... Thankx a bunch

You are welcome.
Please quote context when replying. I see you are using
Google groups. This (comp.lang.c) is not a google group
but an NNTP group that google can access.
Please remember:
- don't top post
- quote enough context so other people can understand
what you are replying to, even if you are replying to one
of your posts
- don't snip the authors of posts when you remove irrelevant
pieces of text
I know the default reply link in Google Groups doesn't
automatically quote the post you're replying to so
don't use that. Instead use the Reply link available when you
click on show options.

Thank you.

Then perhaps posting to Usenet wasn't the best way to get information.

Why do you need to do this, and why is it so urgent? Is this
homework?

I can't believe this...

file mylibrary.c

void libfoo(void)
{
printf("This function does something useful\n");
}

file mylibrary2.c
void libbar(void)
{
printf("So does this one\n");
}

file test.c

#include "mylibrary.h"

int main(void)
{
libfoo();
libbar();
return 0;
}
Now play with your compiler until things work as you want.

Then write the real library.

Hi,
This is not homework but something related to my project. One of my
modules is to develop a generic library for the DNS NAPTR Query and I
don't have any previous experience in this.

Code does not have to be in a generic library, or even in a library,
to function. You can simply write some functions and include
these functions (in the form of source code file(s)) in the set
of files compiled for each program. If you need working programs,
figuring out how to make libraries should not be a source of
urgency.

Hi,
The concept would work great with me but my Manager wants me to
develop such a library. It is for the sake of the specs given to me
that I have to develop this library.

Hi Sunil,
Thanks so much for the link. Yes, that's exactly what I wanted. Thanks
again!

Timmy.

Gordon, *please* don't snip attributions. Thanks.

Argue about it. The time to put things in a library is after they
have been thoroughly tested and their interface shown viable.
Especially the interface. In general the standard library
interfaces have been shown to be useful and viable, apart from
gets.
