fortran-curl

A collection of ISO C binding interfaces to libcurl ≥ 8.10.0 for Fortran 2008. The library has been tested with GNU Fortran 14. See COVERAGE for an overview of bound procedures.

For a user-friendly, high-level HTTP library based on these bindings, see http-client.

Build Instructions

Install libcurl with development headers. On FreeBSD, run:

# pkg install ftp/curl

On Debian, instead:

# apt-get install libcurl4 libcurl4-openssl-dev

Clone the repository, then run make to build and install the interfaces to /opt:

$ git clone --depth 1 https://github.com/interkosmos/fortran-curl
$ cd fortran-curl/
$ make
$ make install PREFIX=/opt

You can override the default compilers by passing the CC and FC arguments, for example:

$ make CC=icx FC=ifx

On Linux, you may have to change the prefix to /usr:

$ make PREFIX=/usr

Link your Fortran application against /opt/lib/libfortran-curl.a -lcurl.

Examples

Examples are provided in directory examples/:

• dict queries a DICT server on TCP port 2628.
• download fetches a remote file.
• getinfo prints request-related information to console.
• gopher prints the contents of a remote Gopher map file.
• http makes an HTTP GET request.
• imap examines the INBOX of an IMAP mailbox (SSL).
• mqtt posts a message to an MQTT topic.
• multi makes multiple HTTP requests at once.
• post makes an HTTP POST request.
• smtp sends an e-mail via SMTP (SSL).
• url demonstrates the URL API.
• version outputs cURL version information.

Build an example with:

$ make <name>

Build all by running make examples.

Fortran Package Manager

This project supports the Fortran Package Manager (FPM). To build the project with FPM, run:

$ fpm build --profile release

The example programs are available with the fpm run --example command.

You can add fortran-curl to your fpm.toml with:

[dependencies]
fortran-curl = { git = "https://github.com/interkosmos/fortran-curl.git" }
