curl.h no such file or directory

Question

I installed curl this command (i use Ubuntu):

sudo apt-get install curl

When I test simple program using g++ test.cpp

Answer 1

Instead of downloading curl, down libcurl.

curl is just the application, libcurl is what you need for your C++ program

http://packages.ubuntu.com/quantal/curl

Answer 2

yes please download curl-devel as instructed above. also don't forget to link to lib curl:

-L/path/of/curl/lib/libcurl.a (g++)

cheers

Answer 3

If after the installation curl-dev luarocks does not see the headers:

find /usr -name 'curl.h'
Example: /usr/include/x86_64-linux-gnu/curl/curl.h

luarocks install lua-cURL CURL_INCDIR=/usr/include/x86_64-linux-gnu/

Answer 4

To those who use centos and have stumbled upon this post :

 $ yum install curl-devel

and when compiling your program example.cpp, link to the curl library:

 $ g++ example.cpp -lcurl -o example

"-o example" creates the executable example instead of the default a.out.

The next line runs example:

 $ ./example

Answer 5

sudo apt-get install curl-devel

sudo apt-get install libcurl-dev

(will install the default alternative)

OR

sudo apt-get install libcurl4-openssl-dev

(the OpenSSL variant)

OR

sudo apt-get install libcurl4-gnutls-dev

(the gnutls variant)
