I think my perl is too old. This is perl, v5.10.1 (*) built for x86_64-linux-thread-multi

Not 100% sure yet - not a perl wizard.

I have used instead:

Patch - it seems to work. but if any perl magician laughs at that - i welcome proposals.

i will create pr tomorrow.

Hey @fulara I didn't know the map function (or my usage) was relatively new and would break on older perl versions. I'm a bigger perl noob then you, I would say :smile:

Your code looks fine to me! Thanks for your (future) pr!

I am still testing further - however I have a question. I am slightly worried that the changes you have made are not enough. This does not work for me across a different directory structure.

the autom4te.cfg file has hardcoded paths - hence it does not want to work in different build setups.

in my recipes before I have discovered yours I was doing this nasty hackiness, I think this worked:

   def package_info...
        #uber hacky but maybe works.
        # unfortunatelly autom4te.cfg has hardcoded strings.. so we just rewrite them everytime!
        self.run("sed -i -r \"s@prepend-include .*@prepend-include '{}'@g\" {}".format(autoconf_dir, cfg))

What do you think - am I doing sth wrong?

Can you explain what you mean by different directory structure?

the autom4te.cfg file has hardcoded paths - hence it does not want to work in different build setups.

In 0001-autom4te-relocatable.patch, I replace all @XXXX@ variables in lib/autom4te.in (that gets converted to autom4te.cfg)

in my recipes before I have discovered yours I was doing this nasty hackiness, I think this worked:

The automom4te.cfg file is only consumed by bin/autom4te. That's why I choose to use a regex to replace AUTOCONF_M4DIR with the correct directory.

What do you think - am I doing sth wrong?

I don't know how to reproduce your problem, so I can't say anything. But looking at the history of your previous comment (ignore what was there - I think my packages got confused.), that may be the case.

When I need to compare 2 packages, I create them using a different user/channel. e.g. try to build and use two recipes as autoconf/2.69@cci/stable and autoconf/2.69@fulara/testing. Maybe that will avoid collisions and possible confusion?

Okay, I just failed at making diff, that was the rootcause. Everything works now - thanks for your help, i'll raise pr tmr(!) after i do some more checks.
