make: *** [bin/unix-echo-client] Error 1

Changing unix-echo-client.c:

uint len = 0;
to:
size_t len = 0;

corrects the problem.

(BTW: thanks for turning on -Wall and -Werror: more projects should do that by default!)

PS: gcc 4.4.5 on Ubuntu 10.10 on x86/64.

Thanks for creating the examples. There is a unix-echo-client.c, wonder if there is a tcp socket based echo client?

Thanks

In this case, send() call does not always guarantee to send "n" bytes because cliend->fd is non-blocking mode.
So keeping the buffer (str[]) is needed until all buffer contents are flushed out.

Just cloned on ubuntu 14.04 with the default libev.

This is the #1 google result for "libev examples" - it would be nice if it worked with the most common developer distribution.

Some version of gcc will ignore the linked Libraries if the -l options before the object files:

$ cc -Wall -Werror -lev -ggdb3 -I./include -o bin/unix-echo-server src/unix-echo-server.c obj/array-heap.o
ccVwfl0g.o: In function `ev_loop':
/usr/include/ev.h:826: undefined reference to `ev_run'

It is OK after moving the -lev to the end of the command:

$ cc -Wall -Werror -ggdb3 -I./include -o bin/unix-echo-server src/unix-echo-server.c obj/array-heap.o -lev
