Install

On Linux :

It's quite easy to compile the C source with GCC :

$ make
cc  -W -Wall -pedantic -g   -c -o trurl.o trurl.c
cc   trurl.o  -lcurl -o trurl

On Windows:

  1. Download and run Cygwin installer.
  2. Follow the instructions provided by the installer. When prompted to select packages, make sure to choose the following: curl, libcurl-devel, libcurl4, make and gcc-core.
  3. (optional) Add the Cygwin bin directory to your system PATH variable.
  4. Use make, just like on Linux.

Prerequisites

Development files of libcurl (e.g. libcurl4-openssl-dev or libcurl4-gnutls-dev) are needed for compilation. Requires libcurl version 7.62.0 or newer (the first libcurl to ship the URL parsing API).

trurl also uses CURLUPART_ZONEID added in libcurl 7.81.0 and curl_url_strerror() added in libcurl 7.80.0

It would certainly be possible to make trurl work with older libcurl versions if someone wanted to.

Older libcurls

trurl builds with libcurl older than 7.81.0 but will then not work as good. For all the documented goodness, use a more modern libcurl.
