I am trying to build PortaLib 0.3.0 from source and (after adding "using namespace std;" to mmgr.cpp to get rid of some C++ errors related to new_handler), I get the following error: c++ -DHAVE_CONFIG_H -I. -I. -I.. -march=pentium -mcpu=pentiumpro -O6 -DNDEBUG -fexpensive-optimizations -DUSE_LIBPNG -Wall -Werror -Wno-deprecated -c EventGenerator.cpp `-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead. In file included from /usr/include/math.h:70, from pl3d.h:63, from EventGenerator.cpp:17: /usr/include/bits/mathcalls.h:310: error: expected unqualified-id before "int" /usr/include/bits/mathcalls.h:310: error: expected `)' before "int" I am building on Gentoo with the 2.6 kernel running, gcc version 3.4.6, and make version 3.8. Does anyone know what's up?
