[Starpu-devel] StarPU with C++ (possibly extern) problem

[Usman Dastgeer <usman.dastgeer@liu.se>]

Hello,

I am using recent version of StarPU from svn (checkout 18,04,2011) and having 
some problem when using it with C++. For example, when I try to to compile 
"hello_world.c" given in starpu/examples using "g++", it gives following 
compiler errors:

g++ -I/home/usmda/programs/include -I/usr//include  hello_world.c -c -o 
hello.o -Wno-write-strings
