  Make had returned bad status, install seems impossible

Tried using cpan install but always receive that error I need help on what should I do, I don't have background in perl, I just need to run the regression and that module is required.

This is my first time to install a perl module because it is required in my regression file.

https://stackoverflow.com/q/42031921 indicates Perl is not at fault. Please edit the question to add the installation command and full output. — daxim, Jul 10 '19 at 14:11

So it is not a very easy. But you can build it with some modification. I would also recommend installing a brewed perl instead of using the system perl

$ brew install perl

# Update the CPAN to latest
$ perl -MCPAN -e 'install Bundle::CPAN'

# Install Installer paackage
$ perl -MCPAN -e 'install Module::Install'

Now download the source code from below url

https://cpan.metacpan.org/authors/id/S/SZ/SZBALINT/WWW-Curl-4.17.tar.gz

Extract and it make two changes

Curl.c

#include "curlopt-constants.c"

to

#undef CURL_DID_MEMORY_FUNC_TYPEDEFS
#define CURL_DID_MEMORY_FUNC_TYPEDEFS 0
#include "curlopt-constants.c"

And then in Makefile.PL change

if($e =~ /(OBSOLETE|^CURL_EXTERN|_LAST\z|_LASTENTRY\z)/) {

to

if($e =~ /(OBSOLETE|^CURL_EXTERN|^CURL_STRICTER\z|_LAST\z|_LASTENTRY\z)/) {

And then run the make command in the downloaded folder

The following worked for me (perl 5, version 28, subversion 0 (v5.28.0) built for darwin-thread-multi-2level, XCode 9.4.1):

wget https://www.cpan.org/modules/by-module/WWW/WWW-Curl-4.17.tar.gz
tar zxvf WWW-Curl-4.17.tar.gz
cd WWW-Curl-4.17
cpan Module::Install
