Answer 1

I also had a problem with libcurl.so.4: no version information available 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)`

I solved this by doing the following:

First, I locate the path of libcurl.so.4:

locate libcurl.so.4

the result is:

/home/chenjian/software/curl-7.20.0/lib/.libs/libcurl.so.4
/home/chenjian/software/curl-7.20.0/lib/.libs/libcurl.so.4.2.0
/usr/lib/x86_64-linux-gnu/libcurl.so.4
/usr/lib/x86_64-linux-gnu/libcurl.so.4.3.0
/usr/local/lib/libcurl.so.4
/usr/local/lib/libcurl.so.4.2.0

Second, find the link of libcurl.so.4,type:

ls -l /usr/local/lib/libcurl.so.4

the result:

lrwxrwxrwx 1 root root 16 Aug 16 21:15 /usr/local/lib/libcurl.so.4 -> libcurl.so.4.2.0

Third, remove it and rebuild the link to libcurl.so.4.3.0:

sudo rm /usr/local/lib/libcurl.so.4
sudo ln -s /usr/lib/x86_64-linux-gnu/libcurl.so.4.3.0 /usr/local/lib/libcurl.so.4

Next, check it:

 ls -l /usr/local/lib/libcurl.so.4

well, the output is:

lrwxrwxrwx 1 root root 42 Aug 24 09:23 /usr/local/lib/libcurl.so.4 -> /usr/lib/x86_64-linux-gnu/libcurl.so.4.3.0

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

cmake version 3.2.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

After fixing the bug, I think it may be caused by multi-version of curl, like me, the origin ubuntu environment had one, but I install another one.
