Hello, I have some "legacy code" to compile, using Boost version 1_34_1. The compiler is gcc 4.1.2 (new versions of Boost don't work anymore, and neither newer versions of gcc). It used to go through, but now on 64-bit platforms I get the following build error: In file included from ./boost/spirit/attribute/closure.hpp:24, from ./boost/wave/grammars/cpp_expression_grammar.hpp:16, from libs/wave/src/instantiate_cpp_exprgrammar.cpp:21: ./boost/spirit/phoenix/operators.hpp:355: error: ‘INT_MAX’ was not declared in this scope Now looking into the code that' correct (INT_MAX seems not be declared somewhere). (BTW, there are many other errors like that; that's just the first one.) So, apparently, somehow INT_MAX used to "slip in" by some uncontrolled inclusion, and now this is no longer the case. But what I don't understand: I always compiled it with the same local installation of gcc (4.1.2)? So I guess it is due to a newer version of glibc now installed? So I need to install first an old version of glibc (which?), then make gcc aware of it (?), and then build boost? I would be glad for some help (hints)! Oliver
