Re: Seeking feedback for nng egg

[Matt Welland]

Yes, that was it. I'm not familiar with cmake. To get shared libraries in nng I guess you need to do:

cd build

cmake -D BUILD_SHARED_LIBS:BOOL=on ..

The nng egg built fine after that. Now I'll give testing it a try.

Thanks.

Is nng compiled as a shared library? Because it looks like it’s linking against an archive file.

I'm wondering if my nng install is somehow broken? I compiled and ran the reqrep demo and it works fine.

Huh, weird. I have been trying to replicate whatever is going on, without luck
so far.

Would you mind editing the csc-options inside the egg definition on line 8?

Should look like this:

(csc-options "-C" "-fPIC" "-L" "-lnng")

Then try building again. If the error persist send me the logs and I'll look
into it.

Cheers!
