Hi all, I'm using arm-elf-gcc, compiled with gcc-4.2, and newlib-1.16 to build an application for a LPC2136 board. You're declaring all these variable as extern, but they don't seem to actually exist anywhere.When you say extern std::string nomEnnemi;, for example, you're not actually declaring a variable, but simply promising the compiler that it exists in another file.. You actually do declare these variables, but you only do it in a scope that's local to the InitVariable::InitialiserVariable() function. f1.cpp:(.text+0xc): undefined reference to `foo()' and if you compile f2.cpp on its own, you get this even more frightening one: crt0_c.c:(.text.startup+0x39): undefined reference to `WinMain@16.
