[MSM] Parse error in Visual Studio 2012, not in Visual Studio 2013.
Hello, In the code below, VS 2012 (target v110) underlines the macro name BOOST_MSM_EUML_EVENT_WITH_ATTRIBUTES in the last line with a wavy red line. Hovering a mouse over it shows a tooltip with error report: "Error: not a class or struct name" And if I recall correctly, the code does not compile. The error disappears in VS 2013 (v120). Though in VS 2013 (target v120), if I remove line "namespace msm = boost::msm;", the last line triggers an error again. This time with a different tooltip error report: "Error: name followed by '::' must be a class or namespace name." Am I using MSM incorrectly? Thanks, Vince // BEGIN euml.h #include <boost/msm/back/state_machine.hpp> #include <boost/msm/front/state_machine_def.hpp> #include <boost/msm/front/euml/euml.hpp> using namespace boost::msm::front::euml; namespace msm = boost::msm; BOOST_MSM_EUML_DECLARE_ATTRIBUTE(char*, charp_attr) BOOST_MSM_EUML_ATTRIBUTES((attributes_ << charp_attr), found_attrS) // next line gives error in VS 2012 (target v110), "Error: not a class or struct name". Not in VS 2013 (targ. v12). BOOST_MSM_EUML_EVENT_WITH_ATTRIBUTES(found, found_attrS) // END euml.h
Pardon me: I am using Boost 1.54. Also, there was an unanticipated text wrap in my email client. The line beginning with 'name".' is from the comment on the line before it. Vince On Mon, Oct 28, 2013 at 9:30 AM, Vincent N. Virgilio <virgilio@ieee.org>wrote:

However there was a bug (some missing boost:: in names) which I just fixed in trunk (rev. 86539) so that it should now work (it does with VS 2010). Could you give it a try? Thanks for the report, Christophe
Christophe, Thanks for the response. In fact, I did not recall correctly. The code DOES compile. But the 'parse' error remains. I'll try the trunk when I can. Thanks for the fix. Vince
