error linking libpcre

error linking libpcre

[Stuart Gray]

Hi,

I am building an overo release using kernel 2.6.29. This build was working,
but due to some issues I decided to delete my tmp directory and start the
build again.

It failed at libpcre. I have made no changes in this area.

Here is the tail end of the log file do_compile:

FATAL: oe_runmake failed



When I look into the ....arm-angstrom-linux-gnueabi/lib directory I can see
two symbolic links., The libstdc++.so which links to libstdc++.so.6.

libstdc++.so.6 links to itself.    Not correct !!!!!

I believe it should link to the file libstdc++.so.6.0.10. Indeed if I copy
this file and rename it to libstdc++.so it will compile and link, but  this
does not fix my original problem it only masks it.


Why are the symbolic link targets not set up correctly?????



Any help would be great
