./configure failed for OpenSC on Ubuntu 20.04

[nshah2588]

Problem Description

./configure command doesn't work without errors

Proposed Resolution

I don't know how to do this:

Perhaps you should add the directory containing `libeac.pc'
to the PKG_CONFIG_PATH environment variable

Steps to reproduce

Follow the steps to first download opensc and then run sudo ./configure after extraction of the file

install all the packages you need to build opensc:

sudo apt-get  build-dep opensc

The OpenSC dependencies are described in the Wiki: https://github.com/OpenSC/OpenSC/wiki/Compiling-and-Installing-on-Unix-flavors. The libeac is not mandatory and opensc works just fine without that. The error you got is

configure: error: winscard.h is required for pcsc

which is the missing pcsc-lite. You can install it on ubuntu as already suggested by @popovec.

There is nothing more we could do for you.
