Compile error with direction on fix

[lightningjim]

I did run autogen and compile before running make and go this error

Added "-ldl" to the cudaminer_LDADD variable made it work just fine. It's appears to be a new requirement for Ubuntu 13.04 which isn't necssary for previous. However I have no idea if it's a bad idea for other variations to just "-ldl" in for them or if it'd cause issues as well.

Thanks for the tip, had the same issue on gentoo as well. Just to add one thing, the file that needs editing after doing autogen and configure is the Makefile.

Arch Linux user here, me too. Adding -ldl to the variable in Makefile worked. I'm assuming this is a general Linux problem atm? IIRC -ldl tells it to use LDFLAGS_LINUX so that does make sense...

Same problem for Fedora 20, -ldl fixed the problem.

Thanks, worked here too. Ubuntu 13.10.

I've updated my git and found -ldl is now there automatically, so this looks resolved.
