Common error when you run configure before make && make install:

checking whether the C compiler works… configure: error: in /root/downloads/libzmq-master': configure: error: cannot run C compiled programs. If you meant to cross compile, use –host'.

Add the following into your /root/.bashrc or /home/{username}/.bashrc

[sourcecode language=“jscript”]

export CPATH=/usr/local/include export LIBRARY_PATH=/usr/local/lib export LD_LIBRARY_PATH=/usr/local/lib export LD_RUN_PATH=/usr/local/lib

[/sourcecode]

Logout and login to reinitialize .bashrc or do the following:

[sourcecode language=“jscript”]

source /root/.bashrc

or

source /home/{username}/.bashrc

[/sourcecode]

Return back to running “configure” and that should get you past the error.

Cheers
