Public bug reported:
Heya,
I just spend two hours reading through boost's documentation on result_of
and Spirit and a lot of cryptic error messages. So I thought I should probably
send
my results upstream so others don't have to do that again.
With boost 1.56.0 hugin produces a number of errors in src/tools/ParseExp.cpp.
The first one (with all the junk removed) is:
<<<
/usr/include/boost/utility/result_of.hpp:189:8: error: wrong number of template
arguments (1, should be 3)
struct result_of_nested_result : F::template result<FArgs>
^
/usr/src/hugin-2013.0.0/src/tools/ParseExp.cpp:80:12: error: provided for
'template<class X, class Y, class Z> struct Parser::lazy_if_::result'
struct result { typedef Y type; };
^
>>>
Actually I'm not sure why this part ever compiled successfully, but I
suppose boost just got a bit more strict now...
The second problem seems to be a change in Spirit that makes it
neccessary to rewrite the lazy_functions a bit.
I attached a patch for all problems I encountered when building hugin
(2013.0.0) with boost 1.56.0.
I also just checked and your recent release candidate does not include changes
in this part of the code,
so I'm pretty sure the bug exists also with the 2014rc
** Affects: hugin
Importance: Undecided
Status: New
** Patch added: "fix usage of boost's result_of interface / adapt lazy
functions to _var as a reference"
