$ perl Makefile.PL INSTALL_BASE=${HOME}/perl5 :3: Error: Unable to find 'perl5.swg' mxnet.i:3: Error: Unable to find 'typemaps.i' Warning: -L../../lib changed to -L/Users/arussel7/Projects/mxnet/perl-package/AI-MXNetCAPI/../../lib Generating a Unix-style Makefile Writing Makefile for AI::MXNetCAPI Writing MYMETA.yml and MYMETA.json

Minimum reproducible example

if you are using your own code, please provide a short script that reproduces the error.

Steps to reproduce

or if you are running standard examples, please provide the commands you have run that lead to the error. simply following the instructions at http://mxnet.io/get_started/osx_setup.html I built the mxnet library successfuly but it seems that the swig bindings were not built.

What have you tried to solve it?

I looked through the buildfiles to see where this may be an option that was not included in the build or some similar issue but to no avail.

[sergeykolychev]

@adamcrussell Did you install swig via brew ? brew install swig seems like your swig setup is incomplete. The perl binding can certainly be compiled on OSX Sierra, not sure about El Capitan but I think they should.

[adamcrussell]

yes, I definitely have swig installed. I just confirmed that the swig binary is installed and it's in my $PATH.

I just did a make clean and rebuilt and no swig bindings are being built. Should perl5.swg be built during the build of the shared library? where is this specified in the build configuration files? I can't seem to see any mention of it.

[sergeykolychev]

@adamcrussell perl5.swg is a part of the swig distribution. looks like your swig installation does not have proper perl support ? this is an example of travis test for the perl build on OSX https://s3.amazonaws.com/archive.travis-ci.org/jobs/252115415/log.txt?X-Amz-Expires=30&X-Amz-Date=20170718T175945Z&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAJRYRXRSVGNKPKO5A/20170718/us-east-1/s3/aws4_request&X-Amz-SignedHeaders=host&X-Amz-Signature=edd8b3333475d162c0eed923b2642f9b92d5dd92740b6072f9fc63d75a73b2a9

[sergeykolychev]

@adamcrussell are you using brew or mac ports ? macports seems to have per language packaging http://blog.jdlh.com/en/2015/01/25/pycdio_install_error_swig/ if you're using macports try 'sudo port install swig-perl'

[adamcrussell]

@sergeykolychev thanks! that was indeed the problem. you're right, I am using macports. after port install swig-perl the problem was resolved and I have no built all the Perl modules.

[sergeykolychev]

@adamcrussell cool, thanks, I'll update the docs with this case.

[sergeykolychev]

@adamcrussell can you please close this issue ?

I have the same problem on MacOS M1 Ventura 13.1. after installing swing-perl with macports I get the following:
