Protocol SSL is not working with Curl

Question

I am trying to clone Wayland repository from git (for a project) but git clone command is throwing me an error.

I installed curl (from here). After cloning make && make install. Earlier I had a different version which was working fine with git.

Then I again tried cloning Wayland repository and this error popped.

fatal: unable to access 'https://github.com/nobled/wayland.git/': Protocol "https" not supported or disabled in libcurl

so tried building curl as ./configure --with-ssl=/usr/local/ssl but I am not able to make any visible changes in curl's behaviour

/usr/local/ssl is a bad --with-ssl prefix!

I also tried this with /etc/ssl/ but failed

/etc/ssl is a bad --with-ssl prefix!

Any suggestion what may have caused this?

Answer 1

The switch

--with-ssl={gnutls,openssl}

needs the location of the the header files (*.h) usually in /usr/include/openssl it's a good idea to run configure with --includedir=/usr/include/ telling configure where to look for includes.

If /usr/include/openssl exists on your system and is having *.h files - it should be the right place.

You need to install the

openssl-devel (cent / redhat with yum) or libssl-dev (debian, ubuntu with apt) package otherwise. (Or clone the files from github.com 1.1.1 stable branch).

--with-ssl=/usr/include/openssl

EDIT2:

Make sure it's openssl v1.0.2. Compiling curl doesn't seem to work with openssl v1.1.1a
