Hello List,
Problem:
I recently updated the CVS trunk and successfully built (userlevel)
Click. When attempting to `make clean install` on the Clicky
application, I receive errors.
Quick synopsis:
The errors are a result of an overloaded swap() function defined in
include/click/algorithim.hh. Buried in the gcc compiler, there is an
ambiguous call to swap() causing the compiler confusion. I was unable
to track down the culprit and ask for mailinglist help.
Pedigree:
Fedora 9
Intel quad Zeon
Kernel 2.6.27.24
gcc 4.3.0
I have attached a copy of the errors for reference.
Thank you,
Derek
