[GAP Forum] GAP 3.4.4 on modern linux

[Max Neunhoeffer]

Dear R Borgo,

You might try what I propose under
  http://www.math.rwth-aachen.de/~Max.Neunhoeffer/Computer/compgap.html

However, your output suggests that you encounter another problem,
probably due to a newer C compiler. If this does not work, please send
be the output of
  gcc -v
since I guess that you are using GCC >= 4.1, maybe it is also a
problem with a newer C library. I myself do not have access to such a
modern system as of now and therefore might not be able to help very
much. But if the problem persists, please ask again.

Best regards,
  Max
