How to check Linux version with Autoconf?
- by Goofy
My program requires at least Linux 2.6.26 (I use timerfd and some other Linux-specific features).
I have an general idea how to write this macro but I don't have enough knowledge about writing test macros for Autoconf. Algorithm:
Run "uname --release" and store output
Parse output and subtract Linux version number (MAJOR.MINOR.MICRO)
Compare version
I don't know how to run command, store output and parse it.
Maybe such macro already exists and it's available (I haven't found any)?
