gcc 7.2.1+20171224-2 lib32 directory

Hello everyone, I'm new to this forum and as many newbies I've come with an issue related to Arch Linux. I've been using Arch for the past 2 and half years running a 64bit install of Arch. What I am interested now is why gcc package, the 64bit version, comes with a lib32 directory that's populated by some files:

┌(kagaroth)─(Shouryuu)─(4.14.12-1-ARCH)
└─(download)─(11 files, 5,0GB)─ $ la /usr/lib32/
total 4,7M

-rw-r--r-- 1 root root 301K 07.01.2018 21:44 libsupc++.a

Seems like this appeared in gcc with version 7.x as in 6.3.1 there's no lib32 directory. Now is this okay? If I'm not mistaken .spec files are used to generate rpm packages so is this something that the devs forgot to remove from the package content?

I've checked ALA and gcc-6.3.1-2-x86_64.pkg.tar.xz have only the /usr/lib directory which is normal for a 64bit install.

/usr/lib32/ is not a simlink to /usr/lib as is /usr/lib64/ but is a real directory residing on the filesystem.

Sorry I've looked around but saw no other topic related to this so called issue and also I'm not quite sure if this is the right place to post it.

This is a recent change following on from the dropping of 32-bit support. See https://lists.archlinux.org/pipermail/a … 29034.html

I'd guess that it has something to do with the recent merge of gcc-multilib into the gcc package.

Kagaroth · 2018-01-09 15:34:26

Thank you very much. I saw the news about dropping 32bit support in 2017 but never thought the devs would merge gcc-multilib into gcc package.

PS: Should I mark this as solved as you have already answered my question by assing [Solved] to the title?
