Description:
Compile for python 2.7.14 error macOS 10.13.2 High Sierra

I'm using this tutorial for macos, brew and case-sensitive : https://wiki.openwrt.org/doc/howto/buildroot.exigence.macosx

here the terminal stderr:

config.log

Thanks for the respond...

[commodo]

I wish this report would have come a few months ago when I still had a Mac :)

I'll try to guess via the config.log output, but the overall building-on-a-Mac is problematic after each version that gets released.
And homebrew also changes from time to time.
Last I checked was Sierra.

I'll probably try to find a solution [MacOS X on a VM, or something] to take a look.

[kholisrag]

That's Fine...
I just can build Ubuntu in VM too...
It's nothing major for me...
Thanks for your hard work...

This was caused by 1c54e2b which added -Wl,--no-as-needed to build flags on all platforms. This flag is not supported by the macOS linker.
Reverting that commit helps a bit but unfortunately I have further problems with the _ctypes module: #5638

[commodo]

that flag ( -Wl,--no-as-needed ) was added to support Ubuntu 12.04 ; which is one of those distros people like to keep around forever ;
maybe some sort condition could be added to check for build-host and add it on Linux ;

regarding ctypes ; will move discussion to other issue

[commodo]

maybe we could do

ifneq ($(HOST_OS),Darwin)
 HOST_LDFLAGS += \
	-Wl,--no-as-needed -lrt
endif 

i admit it would be saner/better to check for linker, but that seems a bit more difficult atm ;

@kholisrag
can you please test with the changes in PR #5758 ?

thanks

Maybe the issue is now too old to have a final confirmation, but it's likely that it has been fixed by the commit referred here above.
