The problem is what Derek (warlord) told you on irc: The libxml headers are pulled in from a C header to be compiled with the C++ compiler, and g++ objects. The problem seems to be that you have an ICU-enabled libxml2 and the ICU headers are detecting C++ and  including the c++ standard library, which is 99% template code.

Try passing -DU_SHOW_CPLUSPLUS_API=0 in CXXFLAGS. I hope that that will force icu to stick to C.

If that doesn’t work I think you’ll have to build a libxml2 with --disable-icu off in a corner somewhere and tell GnuCash’s configure to use it instead of the system one.
