Build boost on msvc7.1 without native wchar_t
Hi!
I try to compile boost using bjam and toolset=msvc-7.1. To comply with the
rest of our libraries I need boost to build without the native wchar_t type.
So far none of the solutions I have found seem to work

So far none of the solutions I have found seem to work ("snative-wchar_t=off", "-sBUILD=
off") In boost\tools\v2\tools\msvc.jam I found a line that adds /Zc:wchar_t to the CFLAGS. Removing that entry didn't help either.
I imagine because native wchar_t is now the default -- you would have to replace that option with the one that explicitly calls for non-native wchar_t. - Volodya

In VC 7.1 there is no explicit option to switch of native wchar_t (as opposed to VC8 and newer, where a /Zc:wchar_t- exists). So as long as some default mechanism in boost build adds the native wchar option, there is no way to unset it, or is there?

You said above you are hacking that mechanism. Specifically, this line in msvc.jam: toolset.flags $(toolset).compile CFLAGS $(conditions) : /Zc:forScope /Zc:wchar_t ; This is the only place where this option is added. If you removed it there, did you cleaned & rebuilt everything? (Use bjam --clean). You can use "bjam -n" to see the commands that are executed, and check if that option is still passed or not. - Volodya
