Porting Eigen3 library for Chrome's Portable Native Client (PNaCl) build error

Vote count: 0

So I have an AWS instance (the free tier one) running with Ubuntu 16.04. There I have installed nacl_sdk (which is working and has allowed me to access their sample sites with success) and naclports which I used to port opencv with which I had trouble with at first due to errors with zlib but got it working after I added i386 architecture and did sudo apt-get update on the system and installed necessary i386 programs.

Note I have depot_tools installed as well.

Now I am trying to install the eigen3 library for pnacl as well but I am getting an error and I am not sure how to understand it nor how exactly it gets built to fix it.

The command that I ported opencv with was

$ NACL_ARCH=pnacl make opencv

And I tried these two commands for building eigen3 with the same results (shown below)

$ NACL_ARCH=pnacl make eigen3
$ bin/webports install eigen3

This is the very end of terminal output (the entire message is very long):

test/CMakeFiles/http://ift.tt/2kmYuqV: recipe for target 'test/CMakeFiles/http://ift.tt/2k3CWDs' failed
