[Lemon-user] using lemon and BGL: ignore_unused_variable_warning

[Balazs Dezso]

Hi,

I checked both the LEMON and BOOST codes, but the two functions are in 
distinct namespaces. Did you use 'using namespace *;' for both libraries? If 
yes, please try to omit one of them (the namespaces in C++ are aimed to solve 
such problems) with explicit using of the necessary classes. Otherwise, please 
send a bug report to our issue tracker with a short example code.

Best, Balazs
