Hi everybody,

I've been trying to use sockets now that they are included in phobos, but I must have forgotten to do something somewhere. When I try to compile a file containing just "import std.socket;" in it, dmd spits out a bunch of errors I don't really understand :

gcc sockets.o -o sockets -lphobos -lpthread -lm

/usr/lib/libphobos.a is the last libphobos.a from the 0.88 zip archive.

Anyone knows where the problem could come from ? (I probably overlooked something evident somewhere :)

Thanks.

You need a main method. You'll find that you get that error upon importing any module. Try adding:

int main(char[][] args) { return 0; }

to your file.

OMG, I'm so ashamed :-/

Actually I accidentaly launched a compilation before writing anything else, and after seeing the errors I didn't even try to go further...

Well, next time I'll ponder a bit before getting in panic :)

Thanks

We all do something like this every now and again :)

If the compiler error was clearer...

You mean somthing like the following, which is written in the third line of the error?

" In function `main':
: undefined reference to `_Dmain' "

Yes, without the others.. so it's clear.
