How to Fix Configure: Error: Please Reinstall the libcurl Distribution

Issue

While compiling PHP with cURL support we get the error below:

checking for cURL support... yes
checking for cURL in default path... not found
configure: error: Please reinstall the libcurl distribution -
    easy.h should be in <curl-dir>/include/curl/

Even, the package libcurl is already installed on the server:

# yum list installed | grep curl
curl.x86_64                          7.29.0-59.el7_9.1              @updates
libcurl.x86_64                       7.29.0-59.el7_9.1              @updates

Solution

In this, we have to make sure that the libcurl-devel package is installed on the server, if it is not then install it first as follows:

sudo yum install libcurl-devel -y

# yum list installed | grep curl
curl.x86_64                          7.29.0-59.el7_9.1              @updates
libcurl.x86_64                       7.29.0-59.el7_9.1              @updates
libcurl-devel.x86_64                 7.29.0-59.el7_9.1              @updates
python-pycurl.x86_64                 7.19.0-19.el7                  @anaconda

And then try to re-compile PHP with cURL and it should be able to compile this time.
