musl xclock?

musl xclock?

[-- Attachment #1: Type: text/plain, Size: 5859 bytes --]

I'm trying to build a musl version of xclock. If I can build xclock then I
hope to be able to build my app which is more complicated. I'm getting the
following error.

/usr/bin/ld: h_errno: TLS definition in //lib/i386-linux-gnu/libc.so.6
section .tbss mismatches non-TLS definition in
/home/mudd/musl/musl-1.1.8.install/lib/libc.so section .bss

Here's what the make was trying to execute. It looks good to me. Do you see
a problem?

Yes, you're linking to glibc, or to something that was linked with
glibc. You should look though the X11 .so files you've built using
readelf and see if any of them have dependencies on libc.so.6. It
looks like you're using the host system's gcc and passing the
musl-gcc.specs file to it manually rather than using the musl-gcc
script or a real musl-targetted compiler toolchain, so it might be
something to do with that too. Adding -v to the command line and
seeing what gets passed to the linker command could be helpful.

It doesn't look like any of my musl compiled libs point to libc.so.6.
$ readelf -a ./*.install/lib/lib*.so | grep libc.so.6
$

Here's what the X11 libs point to. I've built and referenced all of these
dependencies using musl.

I'm using musl-gcc. What I listed in original email is what that script
executed. After I cleaned it up to make it easier to read.

Here's the output of the gcc command with "-v". It's referencing the native
libc. But where does that come from?

Using built-in specs.

You're only checking the X libs (libX*). Can you re-run that command
as:

readelf -a ./*.install/lib/*.so | grep NEED | sort -u

That might find a library that was built incorrectly. I would also
check musl libc.so itself just to be sure; it's conceivable that
something went wrong in the build and _it_ has a dependency on glibc
encoded in it (which it would ignore at runtime, but ld won't ignore
it when linking).

I don't see any references to it on the command line it passes to the
linker, only in the output during linking that was the same without
-v. So I'm confused where it's coming from too.

This is the interesting command...

...and the only mildly suspicious thing is this last -L. Is it
possible that your distro has glibc libc.so in the same directory as
the gcc libs dir, /usr/lib/gcc/i686-linux-gnu/4.8/?

It's odd that //lib appears in the above output since that has nothing
to do with the -L pathnames above and it has a gratuitous double slash
at the beginning.

What distro are you using?

it seems to be an ubuntu gcc

libc.so should not be in that dir but libstdc++.so is there
(which has libc.so.6 and ld-linux-x86-64.so.2 dependency among
others)

if the problem is what i think it is then an empty ld-linux-x86.so.2
may fix it

the first / comes from the default sysroot (gcc was built with
--with-sysroot=/) and i think gcc falls back to that when it
does not find something in the specified places..

i meant ld-linux.so.2 (since it is i386 not x86_64)

But how is /lib being searched at all? It's not in the -L path.

Uhg, is there any way around that? If not, the musl-gcc wrapper is
useless with sysrooted toolchains. :(

I tried creating an empty ld-linux.so.2 in /usr/lib/gcc/i686-linux-gnu/4.8/
and also in /home/mudd/musl/musl-1.1.8.install/lib/. I'm not sure if either
is what Szabolcs Nagy suggested but neither seemed to make a difference.

I might be on to something...



I added --verbose to the collect2 command.




It listed this:

libz.so.1 needed by /home/mudd/musl/libXft-2.3.2.install/lib/libXft.so
found libz.so.1 at //lib/i386-linux-gnu/libz.so.1
libc.so.6 needed by //lib/i386-linux-gnu/libz.so.1




Back to libXft.so...

This (getting errors when using link to ld-musl-i386.so.1  only happens
when on ths one X11 lib. Is it significant?

ok so you probably forgot to add libz to the -L path
and then ld went ahead and found the wrong one

this is ok

(in general you may also want to look at rpath too)

you probably have an /home/mudd/musl/etc/ld-musl-i386.path
that is visible to the first command but not to the second
(nor to ld).

you may also want to figure out why ld tried the system
paths (it either uses hard coded paths or gets them from
some ld.so.conf, you can figure out what it's doing by
using strace -f on the build command)

i think -L probably wont help: libz is an indirect dependency
not listed as -lz on the ld commandline

in that case ld searches different set of paths
you may want to set LD_LIBRARY_PATH or use -Wl,-rpath-link

I see, so the -L options work for libs specified by -l options but not
indirect libs like libz. Strange. So I added -lz to my collect2 command and
that much works now. I got an xclock executable but... it goes into an
infinite loop when I try to run it.

At least I got past the linker error. Thanks!
