Question

I want to link the zeromq libraries in my build so they do not have to be installed separately on the end users machine.

I configured zeromq using:

./configure --enable-static --disable-shared --prefix=/home/xx/out

but when I do:

g++ -o zclient zmqclient.o /home/xx/out/lib/libzmq.a

I get linking errors:

Can anyone tell me where I am going wrong, or provide me with an alternative method?

Thanks!

Turns out the libraries:

-lsocket -lnsl -luuid

are standard on linux but not on solaris and need to be included in the Makefile like so:

g++ -lsocket -lnsl -luuid  zmqclient.cpp /home/xx/out/lib/libzmq.a   -o zmqclient
