Thank you, Juergen, there is a switch in the pugixml.hpp for the dll export. When I switch this on, it does not complain about not-finding the *.lib.

Dear all,

I have troubles to compile because bjam does not find a *.lib file which I would expect to be there. I am on Windows 7 with Boost 1.50.0 and visual studio 10.

It complains:

LINK : fatal error LNK1181: cannot open input file '..\boost-build\additional\msvc-10.0\release\address-model-64\threading-mult i\pugixml.lib' Which is true, the compiler does not build a pugixml.lib. I don't understand why it is not build, since I am building a *.dll. I would appriciate any help, because I have no clue where I should look for the problem. That is most probably the classical bug that the msvc link.exe does not generate a .lib export library when no visible symbols are available. Do you export your symbols from "pugixml.cpp" via "dllexport/import"? Your Jamfile for "pugixml" seems to contain no controlling define for that.

Yours,

Jürgen
