Hi,

I'm just working on the Xenomai 2.5.1 Debian package and encountered 
non-PIC code (evil! ;-) in the shared libraries (skins libraries).

You can see it with e.g.

$ readelf -d src/skins/native/.libs/libnative.so.3.0.0

The "TEXTREL" tag indicates non-PIC code.

$ scanelf -qT src/skins/native/.libs/libnative.so.3.0.0

Shows the function and code offset of the relocation.

With

$ objdump -d src/skins/native/.libs/libnative.so.3.0.0

I found the actual location of the relocation.

I prepared a patch (attached) that fixes it: First, the relocation 
itself by letting GCC create the address in PIC style. Second, "extern 
inline" looks a bit counterintuitive at first, but according to the GCC 
manual, it seems to be what we want (macro behaviour).

Thanks Jan for reminding me!

bye,
   Roland
