[Lemon-devel] Compilation error with gcc 4.7.1

[Robert Schwarz]

Dear developers

sorry for not opening a ticket, but the Trac registration seems to be
broken:
    "No handler matched request to /register"

I was happily using the Undirector from adapters.h until I updated my
GCC to version 4.7.1 and now get the following error message:

> include/lemon/adaptors.h: In instantiation of ‘lemon::Undirector<DGR>::Undirector(DGR&) [with DGR = DistanceGraph]’:
> DistanceGraph.cpp:194:31:   required from here
> include/lemon/adaptors.h:2280:7: error: ‘initialize’ was not declared in this scope, and no declarations were found by argument-dependent lookup at the point of instantiation [-fpermissive]
> include/lemon/adaptors.h:2280:7: note: declarations in dependent base ‘lemon::UndirectorBase<DistanceGraph>’ are not found by unqualified lookup
> include/lemon/adaptors.h:2280:7: note: use ‘this->initialize’ instead

Following the second note and add the "this->" does indeed solve the
problem.

Occured with Lemon 1.2, but the offensive code is still visisble in the
online code browser.

Best
