C:\Program Files\boost\boost_1_42_0\boost/iostreams/detail/path.hpp(53) : error C2825: 'Path': must be a class or namespace when followed by '::'

Reported by: pele@… Owned by: Daniel James
Milestone: Boost 1.43.0 Component: iostreams
Version: Boost 1.42.0 Severity: Regression
Keywords: Cc:


When trying to compile a project in VisualStudio2005 and using boost1.42 I get errors (when including boost/iostreams for example) that is attached in the "log" that I've created.

I don't get this error on Linux with boost 1.38

I've built my own boost 1.42 as per instructions in "Boost Getting Started on Windows".

I also get those same errors when using 1.42 binaries from boostpro. I don't get them using 1.38 boostpro bins. All on vstudio2005.

Sorry, it's probably too late to fix this for 1.43. I think that the problem is that you're constructing with a char* which is a closer match for the templated constructor (which is intended to be used with a Boost.Filesystem path) than for the const char* constructor. So as a temporary workaround you could try casting to const char* when constructing the path. I'll try to come up with a proper fix in trunk soon.

(In [61497]) Only support the templated constructor for types with an 'external_string_type' member. Refs #4135.

Using SFINAE, I might add a workaround for compilers that don't support it, although I'm not sure if there are any that Iostreams supports.
