std::va_list namespace problem

[talanchor@…]

On QNX Neutrino 6.3.2 boost.serialization fails to compile because va_list is not in std namespace. Problem occurs in the following files: boost/boost/serialization/extended_type_info_typeid.hpp boost/boost/serialization/factory.hpp boost/boost/serialization/extended_type_info_no_rtti.hpp

One way to fix this is to include stdarg.h instead of cstdarg and use va_list instead of std::va_list

a) what does "fails to compile" mean? Does the file cstdarg not exist? b) Hopefully I would prefer to find a "cleaner" way to do this that wouldn't require a a lot of changes - perhaps hoisting va_list to the std namespace - which is what I believe that the cstdarg file does. c) perhaps you might like to provide a suggested patch to the required files.

a) I mean compilation errors, cstdarg does exist, but va_list is not in std namespace b) c) If using stdarg.h instead of cstdarg is not 'clean' solution, then patch will be useless. It's QNX-specific bug.

Here is qnx specific workaround on va_list

An alternative fix could be to reuse the similar change for LIBCOMO in factory.hpp to add the std:: namespace to the existing va_list implementation.

I have successfully build boost 1.42 with gcc 4.3.3 (qcc toolset) on QNX 6.4.1.

I will attach the one line patch, too.

Alternative patch, single change only

All right, now you're talking !

I'm puting this in, it will show up next release.
