Incompatible dependencies when linking

[ppires]

I tried to build this tool following the instructions on the README, and got some errors during the linking phase:

And finally my system:

Why are these dependencies incompatible?

Thanks for the help!

My advice is to forget about prepare_dependencies completely. If you want to produce software that you trust, you should understand the provenance of all your dependencies. That goes doubly true for any crypto code.

Get the newest versions of openssl and curl. Build and install them first. Then do the rest for the other libraries. Remove external-dependencies completely, delete all the cmake cached data and try to build and link again.

OR... since you are Linux based, just install the required packages with apt-get. Something like
sudo apt-get install libcurl4-openssl-dev libjsoncpp-dev libgoogle-glog-dev libgflags-dev

Thanks for filing the issue, but we deprecated this repository, so closing.
