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.
This package is known to build and work properly using an LFS-11.2 platform.

User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/curl
Install cURL by running the following commands:
./configure --prefix=/usr \
--disable-static \
--with-openssl \
--enable-threaded-resolver \
--with-ca-path=/etc/ssl/certs &&
make
To run the test suite, issue: make
test. Four tests, 1139, 1140, 1173, and 1177, are
known to fail due to missing executables from the optional
dependencies. If Samba is installed, the related tests will output
a message duplicated many times complaining the Python module
impacket (not a part of BLFS) is missing and be skipped. If libssh2
is installed and the optional --enable-ssh2 is used, a lot of SCP and SFTP tests
will fail.
Now, as the root user:
make install &&
rm -rf docs/examples/.deps &&
find docs \( -name Makefile\* -o -name \*.1 -o -name \*.3 \) -exec rm {} \; &&
install -v -d -m755 /usr/share/doc/curl-7.84.0 &&
cp -v -R docs/* /usr/share/doc/curl-7.84.0
Simple tests to the new installed curl: curl --trace-ascii debugdump.txt
http://www.example.com/ and curl --trace-ascii d.txt --trace-time
http://example.com/. Inspect the locally created
trace files debugdump.txt and
d.txt, which contain version
downloaded files information, etc. One file has the time for each
action logged.
--disable-static: This
switch prevents installation of static versions of the libraries.
--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-openssl: This
parameter chooses OpenSSL as
SSL/TLS implementation. This seems mandatory now.
--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 parameter adds
SSH support to cURL. This is
disabled by default.
--enable-ares: This parameter adds
support for DNS resolution through the c-ares library. It overrides
--enable-threaded-resolver
and is not widely tested by the editors.
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.
