Chapter 14. Networking Libraries

cURL-7.16.3

Introduction to cURL

The cURL package contains curl and its support library. This is useful for transferring files with URL syntax. This ability to both download and redirect files can be incorporated into other programs to support functions like streaming media.

Package Information

cURL Dependencies

Optional

pkg-config-0.22, OpenSSL-0.9.8g or GnuTLS-1.6.3, OpenLDAP-2.3.39, libidn-0.6.14, MIT Kerberos V5-1.6 or Heimdal-1.1, krb4, SPNEGO, and c-ares

Optional for Running the Test Suite

Stunnel-4.21 (for the HTTPS and FTPS tests)

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/curl

Installation of cURL

Install cURL by running the following commands: 

./configure --prefix=/usr &&
make

To test the results, issue: make check. Note that if you have Stunnel and TCP Wrapper installed and you wish to perform the HTTPS tests, you'll need to have an unrestrictive /etc/hosts.deny file.

Now, as the root user: 

make install &&
find docs -name "Makefile*" -o -name "*.1" -o -name "*.3" | xargs rm &&
install -v -d -m755 /usr/share/doc/curl-7.16.3 &&
cp -v -R docs/* /usr/share/doc/curl-7.16.3

Command Explanations

--with-gssapi: This parameter adds Kerberos 5 support to libcurl.

find docs -name "Makefile*" -o -name "*.1" -o -name "*.3" | xargs rm: This command removes man files from the source tree that have already been installed by the make install command.

curl-config

prints information about the last compile, like libraries linked to and prefix setting.
