What can be wrong?

Fix is to use

LPTHREAD=-pthread -lrt

for linux.

[dvv]

doh!

[dvv@pagocmb shine]$ shine sample/httpd.shn
server listening on http://127.0.0.1:8000/

and

[dvv@pagocmb sample]$ ln -s ../lib
[dvv@pagocmb sample]$ shine httpd.shn
server listening on http://127.0.0.1:8000/

Seems like ./lib/sys/ffi must exists on $PWD. I must have missed something...

[dvv]

ok. this fixes:

LDFLAGS=-lm -ldl -pthread -lanl -lrt

-pthread -lrt needed for sys.so et al., -lanl for net.so.

Folks, please, do confirm/void the bug and the fix.

I've tweaked the linux build. Tested on ubuntu 12.10 32 bit. Can you confirm that it works for you?

[dvv]

Fine now. Thanks!
