libcurl.so.4 no version information available

The issue turned out to be I had 2 installs of curl on the system. An apt-get install curl and a curl build from source. I ended up removing the curl built from source and everything works fine now. I also tried later removing the apt-get one and rebuilding curl from source again and all was good. But when I reinstalled the curl from apt-get with the source one still installed, the same issue started again. So I removed the apt-get one again.

In short do not have curl on the system twice, issues happen then.

Sorry if this is not well written, I just got up.

I also had such problem in installing CMAKE, I type cmake, the output is:

cmake: /usr/local/lib/libcurl.so.4: no version information available     (required by cmake)
Segmentation fault (core dumped)`

Something like yours.I fixed it like this:

sudo ln -fs /usr/lib/libcurl.so.4 /usr/local/lib/

Then, I type cmake -version, and the result is

cmake version 3.2.2
