Hello, I am trying to build the source code on my system (Ubuntu 20.04). After cloning the repo, when I proceed with the command: make, I get the following error. I tried installing curl and searched the internet but couldn't get a fix. Please advise, how can I solve this problem.

divyansh:~/gsoc/git$ make
make: curl-config: Command not found

Welcome to the Git community. You need to install the development package of some packages, which come with header files (and not only the libs).

Being a lazy person, I collected all possible package names in a setupscript,
looking similar to this:
  APTGET="sudo apt-get install"
 type curl-config || $APTGET libcurl4-openssl-dev || $APTGET libcurl-devel
 test -r /usr/include/expat.h || $APTGET libexpat1-dev || $APTGET expat-devel || $APTGET libexpat-devel
 test -r /usr/include/ssl.h || test -r /usr/include/openssl/ssl.h || $APTGET openssl-devel || $APTGET  libssl-dev
 test -r /usr/include/zlib.h || $APTGET zlib1g-dev
 type msgfmt || $APTGET gettext

In other words, sudo apt-get install libcurl-devel could help. And you probably need to install more dev/devel packages, unfortunatly different Linux distros use different names for (from a user point of view) the same thing. So I can't tell you out of my head, what Ubuntu needs, but there is hopefully a start point.

As Torsten said you have to install not only a couple of libraries but also the related '-dev' package containing includes and static libraries.

In our CI jobs using Ubuntu we install the following packages by default (see 'ci/install-dependencies.sh'):

UBUNTU_COMMON_PKGS="make libssl-dev libcurl4-openssl-dev libexpat-dev
 tcl tk gettext zlib1g-dev perl-modules liberror-perl libauthen-sasl-perl
 libemail-valid-perl libio-socket-ssl-perl libnet-smtp-ssl-perl"
