[GSOC] fatal error: curl/curl.h: No such file or directory

[Divyansh Garg]

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
    * new prefix flags
    CC attr.o
    CC config.o
    CC exec-cmd.o
    CC gettext.o

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"
