I’m trying to compile my Python helloworld.c again. The former errors are
gone for reasons that are not clear - there’s been a few iterations of
rumprun since then, maybe something in there changed, maybe some other
thing changed I’m not sure. Ugh. I admit I’m somewhat mashing keys and
hoping something works like a monkey writing shakespeare. I don’t like
working that way but I don’t fully understand alot of things so trial and
error helps me learn.
Anyway. Can I trouble you to have a quick look at this command line please
and see if there’s anything obviously wrong? It says "error adding symbols:
Bad value"
As I understand it this command line is telling rumprun-xen-cc to compile
my hw.c and also telling it where the Python headers and shared library is.
(venv3.4)ubuntu@contiki:~/pycy$ rumprun-xen-cc $CFLAGS
-I/usr/include/python3.4m -o hw.xen hw.c -L/usr/lib/x86_64-linux-gnu
-lpython3.4m -lutil -fPIC
/usr/bin/ld: errno: TLS reference in hw.xen mismatches non-TLS reference
in /home/ubuntu/rumprun/platform/xen/rump/lib/libc.a(errno.o)
/home/ubuntu/rumprun/platform/xen/rump/lib/libc.a: error adding symbols:
Bad value
collect2: error: ld returned 1 exit status
and the exact same command works if I use your simple.c application.
(venv3.4)ubuntu@contiki:~/pycy$ rumprun-xen-cc $CFLAGS
