Description Alec Ari 2020-04-25 02:14:52 UTC
sys-libs/ncurses fails to build due to an access violation while "checking for linker search path."



Reproducible: Always

Steps to Reproduce:
I'm using musl, not sure if this is the problem.

1. USE="-cxx" emerge -av sys-libs/ncurses
2. Wait
Actual Results:  
checking for linker search path...
* ACCESS DENIED:  rename:       /etc/ld-musl-x86_64.path
* ACCESS DENIED:  rename:       /etc/ld-musl-x86_64.path
/usr/lib /lib

Expected Results:  
Not have an access violation

Using musl

I tried replacing lld with the default gold ld linker and switched from clang to GCC, still the same problem.
Comment 4 Mike Gilbert gentoo-dev 2020-04-26 05:10:41 UTC
The configure script calls ldconfig with various options.

On glibc, it stops after calling "ldconfig -NX -v" which succeeds and simply outputs some information.

The version of ldconfig we install for musl doesn't understand the "-N" option, so the call fails. The configure script then calls "ldconfig -v", which attempts to regenerate /etc/ld-musl-x86_64.path.

I'm going to blame this one on the incomplete implementation of ldconfig provided by our musl ebuild.

What does "ld --verbose | grep SEARCH_DIR" output?

This entire bug is caused from the improper cflags and ldflags. I am unable to duplicate it.

ld --verbose | grep SEARCH_DIR
SEARCH_DIR("/usr/x86_64-gentoo-linux-musl/lib64"); SEARCH_DIR("/usr/lib/binutils/x86_64-gentoo-linux-musl/2.33.164"); SEARCH_DIR("/usr/local/lib64"); SEARCH_DI ("/lib64"); SEARCH_DIR("/usr/lib64"); SEARCH_DIR("/usr/x86_64-gentoo-linux-musl/lib"); SEARCH_DIR("/usr/lib/binutils/x86_64-gentoo-linux-musl/2.33.1"); SEARCH_DIR("/usr/local/lib"); SEARCH_DIR("/lib"); SEARCH_DIR("/usr/lib");

I will go ahead and provide a full build.log as well.

Maybe, we don't need to rebuild the cache on musl since there is not equivalent of ld.so.cache.

@Alec Ari.  Can you edit `/sbin/ldconfig` and just comment out line 41.  In context, that's in the switch statement which parses the command line opts.  Tell me if this fixes the issue.

Comment 9 Michael 'veremitz' Everitt 2020-04-27 13:35:14 UTC
This looks all kinds of wrong. The configure tests as run standalone are fine, the ldconfig in gentoo's musl looks innocuous enough, so this is a 'feature' of sandbox? or a conflict between that and upstream's configure....

I can't presently identify where this rename is being called from, but I shall investigate further....

Comment 11 Michael 'veremitz' Everitt 2020-04-27 13:53:00 UTC
I can't reproduce it here either, as previous comment confirms.
Comment 12 Michael 'veremitz' Everitt 2020-04-27 14:00:27 UTC
Try dropping these out of your LDFLAGS and re-try:

"-Wl,-z,now -Wl,-z,relro"
Comment 13 Mike Gilbert gentoo-dev 2020-04-27 14:31:40 UTC
At this point, we need some feedback from the bug reporter to answer questions in comment 5 and comment 8.
Comment 14 Michael 'veremitz' Everitt 2020-04-27 14:41:18 UTC
Or am I barking up completely the wrong tree, and ldconfig is somehow reaching https://gitweb.gentoo.org/repo/gentoo.git/tree/sys-libs/musl/files/ldconfig.in#n144 and balking there?

These are not the problem, passing -fPIC via cflags and LDFLAGS is unsupported for one. There is also no reason for him to be passing CFLAGS to LDFLAGS, he is not using LTO.
Comment 16 Alec Ari 2020-04-27 19:21:25 UTC
Using the gold linker (my default setup)

ld --verbose | grep SEARCH_DIR

ld: fatal error: no input files


Using the bfd linker:

ld.bfd --verbose | grep SEARCH_DIR

SEARCH_DIR("/usr/x86_64-gentoo-linux-musl/lib64"); SEARCH_DIR("/usr/lib/binutils/x86_64-gentoo-linux-musl/2.3464"); SEARCH_DIR("/usr/local/lib64"); SEARCH_DIR("/lib64"); SEARCH_DIR("/usr/lib64"); SEARCH_DIR("/usr/x86_64-gentoo-linux-musl/lib"); SEARCH_DIR("/usr/lib/binutils/x86_64-gentoo-linux-musl/2.34"); SEARCH_DIR("/usr/local/lib"); SEARCH_DIR("/lib"); SEARCH_DIR("/usr/lib");


Using lld:

ld.lld --verbose | grep SEARCH_DIR

ld.lld: error: no input files


I reverted back all the *FLAGS to just -O2 -pipe, left out LDFLAGS completely, rebuilt musl and binutils. I've been using Gentoo for years, even with the -fPIC in there, and never came across a problem like this.

I commented out line 41:

                n|N|C|p)
                        echo "Unimplemented option: -$opt" >&2
                        #exit 1
                        ;;

And it errors out just like before.

Quick test:

ln -sfv /usr/bin/ld.bfd /usr/bin/ld

And the problem goes away.. ncurses just built! So the problem is pointing at the Binutils gold linker! I've been using the gold linker ever since it was introduced into Gentoo and I never had a problem like this either, the only thing I am doing different now is using musl.

Comment 17 Alec Ari 2020-04-27 19:32:02 UTC
I just symlinked /usr/bin/ld.lld to /usr/bin/ld as another test (since --verbose returned an error) and the access violation happened again.

So the Binutils bfd linker (which I really don't like as it's the slowest alternative) is the only thing I can use to build ncurses.
Comment 18 Mike Gilbert gentoo-dev 2020-04-27 19:38:20 UTC
I don't think we really support changing the /usr/bin/ld symlink; it should always point at ${CHOST}-ld.
Comment 19 Sergei Trofimovich (RETIRED) gentoo-dev 2020-04-27 20:47:32 UTC
${CHOST}-ld can also be gold if binutils is built with sys-devel/binutils[default-gold]. I would not rely on specific implementation.

That's what OP's emerge --info has:
> ld GNU gold (Gentoo 2.34 p1 2.34.0) 1.16

That is a reasonable configuration.

I think it's somewhat fine to mess with /usr/bin/ld for small tests (binutils-config used to support it directly). I'd strongly advise not use it for running systems though. Binutils upgrades/switches will mangle it.

Packages that don't support arbitrary linker might want to use 'tc-ld-disable-gold' or equivalent to enforce supported linker. But better fix packages in a more reliable way.

I can reproduce locally the failure in musl stage3 as:
# USE='-cxx default-gold' emerge -v1 binutils sys-libs/ncurses

F: rename
S: deny
P: /etc/ld-musl-x86_64.path
A: /etc/ld-musl-x86_64.path
R: /etc/ld-musl-x86_64.path
C: mv /tmp/ld-musl-x86_64.C2xj09 /etc/ld-musl-x86_64.path
Comment 20 Sergei Trofimovich (RETIRED) gentoo-dev 2020-04-27 20:57:09 UTC
https://wiki.musl-libc.org/faq.html#Q:-Where-is-%3Ccode%3Eldconfig%3C/code%3E? says musl systems have no ldconfig.

And inspecting one locally suggests it's a gentoo script:

"""
$ head -n 5 `which /sbin/ldconfig`
#!/bin/bash -e
# Copyright 1999-2015 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2

ROOT="/"
...
"""

Gentoo might want to do something about it.

I would suggest something of the following options:
1. change it not to update /etc/ if there is nothing to update
2. remove it completely (will probably require slightly tweaking portage)
Comment 21 Mike Gilbert gentoo-dev 2020-04-27 21:00:22 UTC
(In reply to Sergei Trofimovich from comment #19)

Is there a better way to get the linker search path in a configure script?

https://github.com/mirror/ncurses/commit/ac3f601c4de5d916f410c9ba4918194a47345e84#diff-9ceb48203b3fd0a963276aeb22265658R3863

Don't think there is a good way to detect all internal default search paths. Paths differ even across ld.gold/ld.bfd. Nothing should rely on it.

If ncurses just needs library paths overriding then cache variable might be an option. Something like:
    cf_cv_ld_searchpath="${EPREFIX}/usr/$(get_libdir) ${EPREFIX}/$(get_libdir)"

But looking at https://github.com/mirror/ncurses/blob/master/misc/gen-pkgconfig.in#L98 ncurses filters out default -Lpaths from $(libdir). I don't think it's needed. I would say that code should just go away entirely.

Ah, I didn't notice there was a cache variable we can utilize. Thanks for point it out.

I wrote the script. 1 sounds like a good idea.  I don't know about 2 though.
Comment 25 Alec Ari 2020-04-28 00:11:36 UTC
Hey everyone,

I just wanted to say thank you all for looking into this and CC'ing this issue to the departments responsible.

@Mike in regards to #18; I understand the method of a forced manual symlink is not supported, a bad idea, and will be wiped out by a re-emerge. The usage of `ln` was only done for a quick one-time only test as Sergei mentioned in #19.

@Sergei, thank you for confirming this failure on your end as well.

Cheers everyone, and good luck on a fix! I'm glad I was able to help!

I have much faith in the Gentoo developers and am sure they will come up with the right solution.

Stay safe everyone, and thanks again for everything.

Alec
Comment 26 Alec Ari 2020-05-13 05:27:33 UTC
FWIW, I added /sbin/ldconfig to INSTALL_MASK (make.conf) then replaced all the contents of /sbin/ldconfig with the one from Alpine Linux, and sys-libs/ncurses built.

When I went to rebuild sys-libs/musl however, the installation failed:

>>> Installing (1 of 1) sys-libs/musl-1.2.0::gentoo
 * ERROR: sys-libs/musl-1.2.0::gentoo failed (postinst phase):
 *   (no error message)
 * 
 * Call stack:
 *     ebuild.sh, line 125:  Called pkg_postinst
 *   environment, line 2022:  Called die
 * The specific snippet of code:
 *       ldconfig || die

So I added exit 0 to the very end of /sbin/ldconfig and everything seemed fine.

Then I went one more step further and replaced the entire /sbin/ldconfig file with just "exit 0" and everything actually seems OK!

musl by default uses the library search path:

/lib:/usr/local/lib:/usr/lib

As referenced here:

https://www.musl-libc.org/doc/1.0.0/manual.html

So replacing the entire /sbin/ldconfig with exit 0 satisfies sys-libs/ncurses when it's checking the search path. Just wanted to let you guys know.

For now, until this is fixed in mainline or I encounter a problem, I'm going to be using this configuration. It works for me and gets the job done. I understand this is not supported so I will not be opening any bugs pertaining to this.

Alec
