Re: [Minios-devel] [Unikraft] Static Libraries not being linked properly

[Wei Chen <Wei.Chen@xxxxxxx>]

Hi Ajay,

 

I think we have to classify the static-pre-compiled libraries.

For instance, if the static-pre-compiled library is a math library.

It just does some Mathematical Computing and doesn’t depend on

Other libraries. I think this math library can be link to

Unikraft. Another instance, if the static-pre-compiled library

depends on other libraries. You have to guarantee the dependent

libraries are in the Unikraft library pool.

 

In your case, the /usr/lib/x86_64-linux-gnu/librt.a and /usr/lib/x86_64-linux-gnu/libpthread.a

would link to libc.a to solve their link dependencies. But the nolibc

In Unikraft is just a subset of libc.a

 

Regards,

Wei Chen

Hi Wei.

Thanks for the help.

Actually, my original query is how to link pre-compiled (static) libraries in unikraft?

I tried as per the documentation at
http://xenbits.xen.org/gitweb/?p=unikraft/unikraft.git;a=blob;f=doc/guides/developers-app.rst;h=45d9bd5b2bb10b3d04135d66b5162a59d54dc2b6;hb=HEAD#l163

but the libraries do not resolve linking problems.

Or am I understanding it incorrectly? Can pre-compiled static libraries be integrated/linked at all in unikraft?

But the clock_gettime hasn’t been implemented in nolibc or libtime.

If your application just uses this function to print timestampe, you

can implement a dummy function in your code in this time to pass the

linking.
