|Hi,
|removing -lrt I get the following error:

By "removing -lrt", I also meant removing HAVE_CLOCK_GETTIME from
<config.h>.

|I'll tell you as soon as I get it to work.

I hope you can solve the version inconsistency.

Hi,
I should have read time.c. Indeed removing HAVE_CLOCK_GETTIME I'm able
to get to the end of the compilation process.
I still get the "Segmentation error" trying the resulting ruby on the
target, doe.
I guess I must recompile the glibc libraries to match those of the
building system...

Me too, trying to cross-compile the glibc libraries right now.

Thank you again,
Emanuele.
