Thanks Pietro, sqweek,

I can't compile it :-/

Some info:

kix@sys:~/2008110109$ cat Makefile
all:
        g++ -Wall -fPIC -c a.C
        g++ -Wall -fPIC -c b.C
        g++ -Wall -fPIC -c c.C
        9c -Wall -o tryfs.o tryfs.c
        9l -Wall -shared -lthread -o libtry.so a.o b.o c.o tryfs.o
/usr/local/plan9/lib/libthread.a
        g++ -Wall -g -o simple-01 simple-01.C -L. -l try -lstdc++


kix@sys:~/2008110109$ make

./libtry.so: undefined reference to `threadmain(int, char**)'

        /lib/ld-linux.so.2 (0xb7eee000)

In the tryfs.c file:

void
threadmain(int argc, char *argv[])
{
}

Thanks.
