Bug 675368 – sys-fs/lvm2-2.02.145 - /usr/libexec/gcc/aarch64-unknown-linux-musl/ld: ../../libdm/libdevmapper.so: undefined reference to `rpl_malloc'

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description hanetzer 2019-01-14 00:52:02 UTC]

Unsure if this is actually common to all hardware, trying some other flavors
as I write this, but on a gentoo aarch64-unknown-linux-gnu system emerging
sys-fs/lvm2::musl with an aarch64-unknown-linux-musl cross-toolchain the build
fails with undefined references to rpl_malloc and rpl_realloc

A fix/workaround I've found is to set (either in the ebuild's src_configure
or via pkg.env) ac_cv_func_malloc_0_nonnull=yes and ac_cv_func_realloc_0_nonnull=yes

Unsure where such a fix should be made, either in sys-devel/crossdev's site
files or maybe in the ebuild itself (I've seen it/similar hacks in a lot of
in-tree ebuilds).

Other info inbound as I un'fix' it and rerun builds to capture logs and such.

I guess it would help to see config.log if it's dependent on ./configure output.
My guess would be that
    checking for GNU libc compatible malloc... no
is a relevant piece.

Exact same failure on an x86_64-pc-linux-gnu->x86_64-pc-linux-musl cross

Same issue here, added some attachments
