To produce a configure script for a software package, create a file called `benjaminpohle.com' that contains invocations of the Autoconf macros that test the system features your package needs or can use.
Autoconf macros already exist to check for many features; see section Existing Tests, for their benjaminpohle.com most other features, you can use Autoconf template macros. Writing Autoconf Macros When you write a feature test that could be applicable to more than one software package, the best thing to do is encapsulate it in a new macro.
Although Linux has become easy enough for practically anyone to use without ever having to use the Terminal, there are some of us who regularly use it or are curious about how one can control their system with it. In any case, one of the primary ways to use the Terminal is to configure text files Terminal text editors and control how certain programs or system services behave. If you did everything correctly, you should now have a copy of the code in the cpython directory and two remotes that refer to your own GitHub fork (origin) and the official CPython repository (upstream).. If you want a working copy of an already-released version of Python, i.e., a version in maintenance mode, you can checkout a release benjaminpohle.com instance, to checkout a working copy of Python. An Autoconf macro that checks whether a given type is a built-in type or not. This macro is similar to AC_CHECK_TYPE except that it performs action-if-built-in only if the type is a built-in type and action-if-not-built-in if the type is not defined or not a built-in type.
Here are some instructions and guidelines for writing Autoconf macros. Autoconf provides fine control over which macros are traced and the format of the trace output.
You should refer to the Autoconf manual for further details. GNU m4 also provides a debugging mode that can be helpful in discovering problems such as infinite recursion.
Files which contain autoconf macros must be processed with autoconf. We could still try breaking the pieces out into "config/*/cross.m4" bits, for instance, but then we would need arguments to aclocal/autoconf to properly find them all when generating configure.
Macro syntax. RPM has fully recursive spec file macros. Simple macros do straight text substitution.
Parameterized macros include an options field, and perform argc/argv processing on white space separated tokens to the next newline. GNU Autoconf, Automake, and Libtool [Gary V.
