How to Fix Autoconf-style Config Probing
- Posted on 8 Oct 2026 by Boris Kolpackov Configuration probing as implemented in autoconf/CMake/etc involves compiling and linking a test program to determine whether a particular feature, such as a function, is available on the platform being targeted.
- For example, we may prefer to use the strl*() family of functions in our codebase.
- However, these functions are not (yet) standard and are not provided by all libc implementations.
