0.5.0 tests do not compile

[GoogleCodeExporter]

What steps will reproduce the problem?
1. compile run-tests

What is the expected output? What do you see instead?
compiled test

What version of the product are you using? On what operating system?
yaml-cpp 0.5.0, VS 2008, Win7

Please provide any additional information below.
The tests do not compile due to missing overloads for some template functions 
for "const char[]" (which is for example called when accessing doc["somekey"] ).

The attached patch fixes this.

Windows 7x64, Visual Studio 2010 SP1-latest
Run CMAKE to generate solution for Visual Studio 2010 amd64.  Tell it where to 
define boost by adding BOOST_ROOT.  CMAKE is happy to configure and generate.   
Open solution, set to DEBUG mode and x64 architecture.  Right-click ALL_BUILD 
and select "Build".  Lots of pieces do build successfully but these are the 
errors (attached and slightly anonymized).

OK I have an idea, the compiler complains that
include\yaml-cpp/node/detail/impl.h(146): error C2734: 'lhs' : const object 
must be initialized if not extern
because it doesn't want you to do things like
const MyType awesomeVar;
Because then it's not defined and const!
When we do
YAML::Node node = blahblah;
node["key"]
type("key") == const char*
on line 146 of impl.h
T lhs == const char* lhs
and the compiler complains.

I checked it out today, and it appears there was no specialized handler for 
const char[N], only for char[N].  I've inserted the specialized handler code 
and it now compiles and passes most of the tests except a few edge specs.

In line impl.h at line 312, insert
template<std::size_t N>
        struct to_value_t<const char [N]> {
            explicit to_value_t(const char *t_): t(t_) {}
            const char *t;
            typedef std::string return_type;

            const std::string operator()() const { return t; }
        };

Issue 193 has been merged into this issue.

well I'll use 0.3 for now.

does it still compile on g++or clang++ ?

is the fix that much non trivial ?

It does compile on both gcc and clang. I believe the fix is trivial-ish (there 
are a few patches in this thread), but my Windows machine isn't set up, and 
I've been busy lately - sorry, everyone who's waiting for this :(

I encountered the same problem Visual Studio 2010 RTM. While the first patch 
(overloads.diff) seems a little messy to me, it does work.

Fixed (finally!), rf303ab9e8f7c in the default repo.

Please confirm if this compiles for you. Thanks, and sorry for the delay!

Builds and runs without issue.  Thanks for the fix.  When I run_test's though 
only one test runs (and passes) -- did I cmake wrong to miss all the original 
tests?

Thanks for confirming!

The tests are a little non-standard - it's just a single executable, with 
standard output. What's the output that you see?

Ah, I see. Yeah, that's my bad for making it so confusing. CMake makes a target 
called RUN_TESTS, but that actually doesn't do the right thing. What you should 
run is the test/run_tests target (lowercase!).
