i understand the macports compilers offer these featuers, but i was just referring to the operating system features.

i think in this past week i’ve used ports more than i ever have in the past twenty years of installing it, and while your general statement is correct, i must provide some corrections to it below.

with your macports-libcxx, i can’t disagree that macports has everything. but the question is: does it all work out of the box? the answer is ’no’.

examples:

1. the latest gdb is ‘broken’ because it relies on sp_mut from a libc++ newer than what is on 10.7, and the build will fail ‘out of the box’.
	-gdb universal is ‘broken’ because there are more comments needed to the newer makefiles to ensure the libtool archive files do not clash when merging the destroots of i386 and x86_64
2. as explained earlier this week, both nodejs14 and nodejs18 fail to build on 10.7 because no one has tried to build them on 10.7 and look at the issues.
	-the current portfiles simply stop anyone from trying to even install it on macs lower than 10.9
3. lldb-mp-xx will fail pretty badly on (5.0 and up) 10.7, and i don’t think this is just a matter of a libcxx. it took a few involved edits. not saying they were super-hard, but they weren’t easy.

in short, you are correct that users are able to build “any software you want”, but only with some involved  _EDITS_ of the _CURRENT_ portfiles of the aforementioned ports.
	-this is challenging for people who may have experience in development, but none that are relevant to macports (though i’ve leeched for 20 years almost) for two reasons:
		1. there is new syntax/nomenclature/familiarity required in modifying the portfiles themselves
		2. there are changes required to the actual build (i.e. cflags/ldflags etc) that also need to be discovered by ‘playing’ with the build directory in /opt/local/var/macports/build/*software*
	-the knowledge in step 2 then needs to be summarised into step 1, which shows there are two layers of experience to contribute effectively to the macports system.

it is a great front-end and i appreciate it very much, but i really ‘had to care’ before i learned about this two-stage process mentioned above.

of course the next question would be: are we expecting the macports user to know how to do all of this? 
	-i guess that goes to the ethos of the package manager maintainers. 

personally i think i’ve shown i haven’t suffered if that is your expectation. 
	-BUT with some maintenance of existing portfiles for popular software, i think macports popularity could increase significantly and that is the perspective from which i penned this topic.

maybe no one cares about that though lol.
