could not read symbols: Archive has no index?

Hi,

I've successfully build the OpenNL into libnl.a and put it to /usr/lib under Ubuntu 7.04

However, when I try to make a program that uses it, the linker output the following error:

/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../lib/libnl.a: could not read symbols: Archive has no index; run ranlib to add one
collect2: ld returned 1 exit status

So, what may be the problem? I've googling around but no help...

Thanks in advance!

Did you try to do "ranlin libnl.a" [save a copy of libnl.a first!]

s/ranlin/ranlib

I've tried ranlib libnl.a, but no output, no help... still the same error message when I try to compile the program using it.

What about doign "file libnl.a" - maybe you have the wrong version of the file for your architecture, or some such [I've downloaded the wrong version of a file once or twice, and also had bad links so that I got the wrong version even when I clicked the right links].

libnl.a: current ar archive

Is this correct?

I had hoped that it would give some more info.

Perhaps you cand download the source and build it yourself, see how that goes?

Actually this .a file is build by myself from the source :(

Perhaps "ranlib -a" or "ranlib -s" will do what you want - I just looked up ranlib, and those make sense for the problem you see...
