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



Ok Wei, got it ...

So, I added "/usr/lib/x86_64-linux-gnu/libc.a" also in "APPCOREMARK_OBJS-y", but the linking errors still persist.
I now assume that pre-compiled static libc.a CANNOT be added into unikraft, right?

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

Hi Wei.

Thanks for the help.

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

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.
