missing ';' before namespace when using boost 1.4.2

Question

Working on moving some C++ code from Linux over to Windows. The code uses boost 1.4.2, however it keeps failing out on building the boost modules. Basically, every boost hpp file that happens to contain "namespace boost" errors with:

error C2143: syntax error : missing ';' before 'namespace' 

Any idea what could be causing this?

Answer 1

Loss of ; before including Boost header could be cause of that. The following code produce such error:

struct X {}  // << ; lost here

#include <boost/shared_ptr.hpp>

This small code gives me the following error:

boost/config/suffix.hpp(460) : error C2143: syntax error : missing ';' before 'namespace'

Answer 2

Have you tried including these boost headers on the first line? If they compile fine that way, it's likely a missing ; in one of the headers included before them.
