The cURL package contains an utility and a library used for transferring files with URL syntax to any of the following protocols: FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS and FILE. Its ability to both download and upload files can be incorporated into other programs to support functions like streaming media.

The curl pacakge built here has many more depenencies as listed in the optdepends array below, and is somewhat limited. You should consider reviewing the package's optional dependencies and adjusting as necessary.
Create the PKGBUILD for the cURL package with the following commands:
mkdir /sources/curl
cd /sources/curl
cat > PKGBUILD << "REALEOF"

Prepare the build directory for the pacman user and build the package:
chown -R root:pacman . chmod 2775 . chmod 664 PKGBUILD su pacman -c 'makepkg -L --nodeps'
Add the newly created package to the central package repository:
cp curl-8.12.1-1-$(uname -m).pkg.tar.xz \
/srv/pacman/repos/LFS/
repo-add /srv/pacman/repos/LFS/LFS.db.tar.xz \
/srv/pacman/repos/LFS/curl-8.12.1-1-$(uname -m).pkg.tar.xz
Update the local cache and install the cURL package:
pacman -Syu pacman -S curl --overwrite \* -dd --noconfirm
Finally, copy the source files into the source repository and clean up the build directory:
mkdir /srv/pacman/source/LFS/curl cp PKGBUILD /srv/pacman/source/LFS/curl cd /sources rm -rf curl
--enable-threaded-resolver:
This switch enables cURL's builtin
threaded DNS resolver.
--with-ca-path=/etc/ssl/certs: This
switch sets the location of the BLFS Certificate Authority store.
--with-gssapi: This parameter adds
Kerberos 5 support to libcurl.
--without-ssl --with-gnutls: Use to
build with GnuTLS support instead
of OpenSSL for SSL/TLS.
--with-ca-bundle=/etc/pki/tls/certs/ca-bundle.crt:
Use this switch instead of --with-ca-path if building with
GnuTLS support instead of
OpenSSL for SSL/TLS.
--with-libssh2: This paramater adds
SSH support to cURL. This is
disabled by default.
--enable-ares: This paramater adds
support for DNS resolution through the c-ares library. It is
disabled by default, but does speed up DNS resolution queries.
find docs ... -exec rm {}
\;: This command removes Makefiles and man files from the documentation
directory that would otherwise be installed by the commands that
follow.
