Updating the configure script

Trick uses autoconf to find and version check dependencies. The autoconf scripts live in the autoconf/ directory, and the generated script that the user runs is configure in the Trick home directory.

How to update the configure script

The configure script run by the user is generated by autoconf. To update it -

1. Make changes in the autoconf/ directory, likely to configure.ac and macros in the m4/ directory
2. From the autoconf/ directory, run:

aclocal
autoconf -o ../configure

Notes

If you get an error message that looks like

possibly undefined macro: AC_MSG_ERROR

Install the package autoconf-archive.
