There seem to be a problem with copying of submodule headers when building boost from git on Windows. I get a _lot_ of "error C1083: Cannot open include file: 'boost/config/user.hpp': No such file or directory" when attempting to build Boost with VS2012. Manual copying of user.hpp (as well as other "missing" headers) does solve the problem, but this should not be necessary.

Right. This is handled by b2, though not automagically right now.

...

Steps to reproduce: 1: Create a clean Boost git working-copy with all submodules. 2: bootstrap.bat

You are missing

2a: b2 headers

...

3: b2 link=shared runtime-link=shared variant=debug toolset=msvc-11.0

Any ideas for how to avoid this problem?

See the documentation at

https://svn.boost.org/trac/boost/wiki/TryModBoost

for furhter details.

Thanks a lot Jürgen. It would be great if b2 could be improved to do this automatically. Fredrik

The reason boost/config/user.hpp is a problem is that the #include scanner isn't finding it, because it's #included through a macro.

Perhaps if we change the logic from: // if we don't have a user config, then use the default location: #if !defined(BOOST_USER_CONFIG) && !defined(BOOST_NO_USER_CONFIG) # define BOOST_USER_CONFIG #endif // include it first: #ifdef BOOST_USER_CONFIG # include BOOST_USER_CONFIG #endif to: // if we don't have a user config, then use the default location: #if !defined(BOOST_USER_CONFIG) && !defined(BOOST_NO_USER_CONFIG) # include #elif defined(BOOST_USER_CONFIG) # include BOOST_USER_CONFIG #endif that would help? What other cases are there of the scanner missing an include? The rest of config.hpp seems to be OK, at first glance.

Anything that uses BOOST_PP_ITERATE may be an issue.

Yes, and there are too many of these. Some headers use themselves for iteration, but others do not. Oh well, it seemed a good idea at first. :-)
