Arch Linux

Okay i can't edit the task main text but submit happened while i was typing so:

I haven't tried many mirrors but it seems to be the case for most of them

Can confirm, empty static libraries from latest erlang package break building lexbor dependency of fast_html erlang package, dependency of source pleroma servers.

for 24.2-1

```
$ du -sb $(pacman -Ql erlang | awk '/libei/{print $2}')
74254 /usr/lib/erlang/lib/erl_interface-5.1/lib/libei.a
74254 /usr/lib/erlang/lib/erl_interface-5.1/lib/libei_st.a
74254 /usr/lib/erlang/usr/lib/libei.a
74254 /usr/lib/erlang/usr/lib/libei_st.a
```

At least 24.0.4-1 is not having this issue.
```
282530 /usr/lib/erlang/lib/erl_interface-5.0/lib/libei.a
278736 /usr/lib/erlang/lib/erl_interface-5.0/lib/libei_st.a
282530 /usr/lib/erlang/usr/lib/libei.a
278736 /usr/lib/erlang/usr/lib/libei_st.a
```

I believe this same or a similar issue with the Arch's erlang-24.2-1 package is illustrated here:

https://github.com/erlang/otp/issues/5609

The objects in libei.a are reported to have LTO optimization, and they are not being found by the linker.
Note that the same problem is not found in pre-24.2-1 builds, and when the erlang is built locally from the same sources the issue doesn't show up.

This issue seems to be related to this modification of makepkg (https://lists.archlinux.org/pipermail/pacman-dev/2021-March/024911.html), which added mandatory stripping to makepkg.

As the result of stripping the produced `libei.a` archive containing object compiled with LTO don't seem to be linkable any more.
I tried to build the package without applying the strip to libei.a, and all symbols resolve successfully, so `strip` is the culprit here.

As it doesn't seem like `makepkg` has any option to exclude stripping of libraries, but it looks like this issue is getting resolved if setting CFLAGS="-ffat-lto-objects" in the configure command when building the erlang package, e.g.:

./configure CFLAGS="-mtune=generic -O2 -pipe -fno-plt -fexceptions -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security -fstack-clash-protection -fcf-protection -flto -ffat-lto-objects" LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now" AR=gcc-ar RANLIB=gcc-ranlib

It needs to be addressed by the package maintainer.

Thanks for reporting, I'll look into it.

erlang 24.2.1-1 appears to be in order:

286642 /usr/lib/erlang/lib/erl_interface-5.1/lib/libei.a

Can someone please confirm that this is no longer a problem?

The issue appears to be fixed.

Same for me, latest package build seems to be okay.

Thanks for testing and for creating this ticket.
