@ng0177 that's a characteristic of Arch Linux (the entire distribution), and of the AUR. Good to know it worked for you.

@dbermond appreciate the fast response. AUR has the advantage of not needing the split between dev and standard packaging. I simply forgot to install fann, it works flawless.

@ng0177 first of all, there is no such "libfann-dev" or "development package" here, but just the 'fann' package. This package provides the header you mentioned, 'doublefann.h', installed under '/usr/include/doublefann.h'. I have just installed the package perl-cpanplus, and your example command ('cpanp i AI::FANN') works fine for me after installing 'fann' (this package). I get the messages "Module 'AI::FANN' installed successfully" and "No errors installing all modules". I cannot reproduce your issue.

cpanp i AI::FANN fails because it cannot find the header doublefann.h which is in the development package.

@ng0177 I could not understand what you mean. Can you please clarify what exactly is missing in the package?

ng0177 commented on 2026-06-05 06:34 (UTC)

libfann-dev which includes the headers for the cpan perl wrapper seems missing.

@micwoj92 I have added a fix for cmake 4 and now the package is building fine. Thanks for reporting.

Build fails:

CMake Error at CMakeLists.txt:3 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.


-- Configuring incomplete, errors occurred!
==> ERROR: A failure occurred in build().
    Aborting...

Huh? Why not?

@chowbok Sorry, but I cannot support arm architectures.
