compiling C++ in the toolchain.

[Peter Nijs]

Hi,

How can I lake the toolchain compile my code as C++ instead of C? Just 
compiling it like told in the wiki results in:

Which makes me think it's trying to compile it as C instead of C++. I tried to 
rename the source file to main.cpp (and of cource change all references to 
it). Now:

peter at leela:/usr/local/openmoko/source/labyrinth> make
make  all-recursive
make[1]: Entering directory `/usr/local/openmoko/source/labyrinth'
Making all in src
make[2]: Entering directory `/usr/local/openmoko/source/labyrinth/src'
make[2]: *** No rule to make target `main.c', needed by `main.o'.  Stop.

make[1]: *** [all-recursive] Error 1
