[LTP] [RFC PATCH 1/1] configure.ac: Print lib & docparse summary

[LTP] [RFC PATCH 1/1] configure.ac: Print lib & docparse summary

[Petr Vorel]

Due many checks of structs, members etc are library presence and
docparser config results quite hidden. Print them in the end.

Disadvantage of this is need to keep sync m4 macros with configure.ac
also quite easily results can be misinterpreted.

Hi,

If we want some summary I don't see much better way how to achieve it
with autoconf. Maybe we could introduce extra variables in m4 macros
which would be used in configure.ac.

Kind regards,
Petr

Another option would be adding 'make info' target to the top level
Makefile that would print these based on config.mk, not sure if that
would be much better than this though.

While using config.mk would make things easier, I slightly prefer to have info
printed after running ./configure.  Maybe we could even have both. Unfortunately
each would have to have its own implementation, as configure.ac setup IMHO does
not allow to use config.mk output.

Whatever option we use, what'd be worth to print? Just libraries and docparse
(as done in this RFC) or more info from config.mk?

Kind regards,
Petr
