Passing compilation options through to cpan/cpanm

ondohotola has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

Something similar has been asked here before, but It wasn't solved

Of late, the XCode command line tools on Mojave MacOs do not remember the default framework path, which i can however pass to cc by adding -F /Library/Frameworks.

I can of course edit the Makefile.PL, but I would rather prefer to pass it from the command line, because it scales better

Any Ideas?

greetings, el

Hi, I think that cpanm's "--configure-args" capability might be helpful to you here. Check the cpanm documentation. I rarely use any of the cpan* modules, but if you (alternatively) wanted to build modules manually, you could look at the ExtUtils::MakeMaker documentation for (eg) modifying CCFLAGS. One thing that I've successfully used in manual builds is to modify the "CC" setting, so you might find that something like the following works: `perl Makefile.PL CC="cc -F /Library/Frameworks"` [download] If that works, I'd probably just rebuild perl with the `-Dcc="cc -F /Library/Frameworks"` argument.

Not sure about `cpan`; for `cpanm` there is `--configure-args` (experimental), so maybe try: `cpanm --configure-args="CCFLAGS='-F /Library/Frameworks'"`	[reply]

What are you trying to do that is failing? You may be able to resolve this problem by upgrading ExtUtils::MakeMaker, and not need to pass along any extra parameters.	[reply]
