Well, with -E, it is not supposed to compile anything. Find out what the command line is for the particular source file. Suppose it is like: gcc -Dmydefine -Wall -c mysource.c -o mysource.o Now do: gcc -Dmydefine -Wall -E mysource.c > out.txt ... and inspect the generated out.txt to figure things out. -- Ozkan ------------------------------------------------------------------------------ Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.
