I have installed EURANE patch to ns-2.29.3 release on Fedore 5 core
(kernel version 2.6.15, gcc version 4.1.0).
Without the EURANE patch only some validation tests on test-suite-red.tcl
fails that is the known problem with the Fedora core
However, after EURANE patching more validations tests fail:
Test output differs from reference output
Diagnose with: diff test-output-wpan/wpan.test test-output-wpan/wpan
Or see URL "http://www.isi.edu/nsnam/ns/ns-problems.html".
Some test failed.

These messages are NOT errors and can be ignored:

validate overall report: some tests failed:

to re-run a specific test, cd tcl/test; ./test-all-TEST-NAME
Notice that some tests in webcache will fail on freebsd when -O is turned on.
This is due to some event reordering, which will disappear when -g is turned on.
Has someone else noticed the same behaviour with the EURANE patch and/or analysed
what may be the reason and how meaningfull/serious the variations in
the results are? Any idea how to correct the patch?
BTW. To make EURANE patch work in 2.29.3 you don't need gcc patch for
ns-2.28. However, you have to check manually EURANE patch code
because due to differences between
2.28 and 2.29.3 all files cannot be patched correctly.
Thanks in advance
