Description Tom Henderson 2008-10-10 17:34:22 UTC 
./waf --lcov-report works for the unit tests, but not for examples or regression.

How to reproduce:
./waf configure --enable-gcov
./waf
./waf check
./waf --lcov-report 

(works so far, but then)
./waf --regression
./waf --lcov-report
exits with this error:

./waf --lcov-report

Comment 1 Tom Henderson 2008-10-10 17:37:09 UTC 
A note on this configuration:

for ns-3, there is a specialized version of lcov-1.4 that resides in utils/lcov directory.  The current stable version is lcov-1.6.  Note that any attempt to migrate lcov-1.4 to lcov-1.6 in utils/lcov should preserve the existing patch (plus whatever is needed to make it work on regression).
Comment 2 Tom Henderson 2008-10-23 00:33:33 UTC 
agreed on 10/22 to try to fix this for 3.3 release (non-blocker)

The same error happens with lcov 1.6

a simple fix is to ignore the error from the wscript and proceed with html generation anyway.
