Compiling php with curl, where is curl installed?

Question

I need to specify a directory when compiling php with --with-curl=

The curl binary is located at /usr/bin/curl

curl -V gives me

curl 7.15.5 (x86_64-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5 

locate curl gives me

/usr/bin/curl /usr/lib/libcurl.so.3 /usr/lib/libcurl.so.3.0.0 /usr/lib64/libcurl.so.3 /usr/lib64/libcurl.so.3.0.0 

removed /usr/share/... and other irrelevant files

UPDATE

Tried --with-curl=/usr/lib64 and --with-curl=/usr/lib although I'm pretty sure it's 64 bit.

checking for cURL support... yes checking if we should use cURL for url streams... no checking for cURL in default path... not found configure: error: Please reinstall the libcurl distribution -     easy.h should be in <curl-dir>/include/curl/ 

SOLUTION

PHP requires curl-devel

Answer 1

None of these will allow you to compile PHP with cURL enabled.

In order to compile with cURL, you need libcurl header files (.h files). They are usually found in /usr/include/curl. They generally are bundled in a separate development package.

Per example, to install libcurl in Ubuntu:

sudo apt-get install libcurl4-gnutls-dev 

Or CentOS:

sudo yum install curl-devel 

Then you can just do:

./configure --with-curl # other options... 

If you compile cURL manually, you can specify the path to the files without the lib or include suffix. (e.g.: /usr/local if cURL headers are in /usr/local/include/curl).
