libidn not found with Homebrew on Mac

[ondohotola]

I am unable get Zonemaster:LDNS to compile on iMac/MacPro x86_64 MOnterey 12.1 with CPAN updated to latest.

It does not find libidn, which is installed from Homebrew.

From what I see it's just something similar like --prefix-openssl which needs to be added to the Makefile.PL, even though I see this in /usr/local

Could you test the proposal in #152 to see if this solves your issue? (I don't have access to Mac).

[marc-vanderwal]

@ondohotola Do you have any news on this issue? Have you had the chance to test the proposed fix?

[ondohotola]

Thank you.

On my M2 MacMini the following worked (your milage will vary, and if it squeals about missing Perl Modules, just install them with cpan):

cpan Zonemaster::LDNS (which fails but that's fine)

cd $HOME/.cpan/build/Zonemaster-LDNS-4.0.2-0
HB=$(brew --prefix)
OSV=$(openssl --version|awk '{print $2}')
perl Makefile.PL \
   --prefix-openssl=$HB/Cellar/openssl@3/$OSV \
   --libidn-inc=$HB/include \
   --libidn-lib=$HB//lib
make
make test
make install
cpan Zonemaster::Engine
cpan Zonemaster::CLI

zonemaster-cli --version then shows

Zonemaster-CLI version v7.0.0
Zonemaster-Engine version v6.0.0
Zonemaster-LDNS version 4.0.2
NL NetLabs LDNS version 1.8.3

and zonemaster-cli --level ERROR na

shows

Seconds Level    Message
======= ======== =======
  65.90 ERROR    It cannot be determined if the child zone is signed or not.

whereas the Web GUI shows no error

Can you run again with --show_testcase --level INFO?

[ondohotola]

I'll email the output to you off line, as I don't want to post it her.

[ondohotola]

Just for the record Mats and I are indeed engaging off line :-)-O

It compiles out of the box on the Intel Mac, which leads me to requesting that perhaps the configure step should look not only for /usr/local but also for /opt/homebrew or even better test for Homebrew installation

if [ "$(command -v brew)" ]; then
   HB=$(brew --prefix)
fi

and

OSV=$(openssl --version|awk '{print $2}')

and if it exist add $HB to the tests like I did above, ie something like

perl Makefile.PL \
   --prefix-openssl=$HB/Cellar/openssl@3/$OSV \
   --libidn-inc=$HB/include \
   --libidn-lib=$HB/lib

We might want to consider using pkg-config to discover potential locations of the required libraries. Using pkg-config is more likely to be portable across *nix platforms.

[ondohotola]

That should work
