bug#49102: guix environment regression

[Mathieu Othacehe]

Hello,

When using guix@caf4a7a2, I cannot no longer build a functional
guix-daemon using the following classic commands:

--8<---------------cut here---------------start------------->8---
guix environment guix
./configure --localstatedir=/var --sysconfdir=/etc
make -j4
--8<---------------cut here---------------end--------------->8---

--8<---------------cut here---------------start------------->8---

mathieu@elbruz ~/guix [env]$ ./pre-inst-env guix-daemon

When rolling back to an older guix@f1bfd9f, things work as expected. The
regression probably lies in between those 1084 commits. I'll try to
bisect more precisely later on.

Thanks,

Mathieu

The bisection leads to this commit:
8cef92d0633850d97c1a1d4521812268f56672be, but it doesn't appear clearly
to me what could cause the regression.

Fixed in b9a95420abdf4ae7fe9a347031278a44ad6a1cce.

The problem was that the profile was built with inputs in the wrong
order.  Thus, ‘ld’ from Binutils would “win” over ‘ld’ from ld-wrapper,
hence the build failure above.

Thanks for reporting + bisecting!
