Bugzilla Bug 173317

When trying to compile net-p2p/mldonkey-2.8.4 i only get the init.d, conf.d and
/usr/bin/mldonkey script. Error message:

!!! dobin: mlnet does not exist
!!! dobin: mld_hash does not exist
!!! dobin: get_range does not exist
!!! dobin: copysources does not exist
!!! dobin: make_torrent does not exist
!!! dobin: subconv does not exist

Some error message that is maybe connected to it:

And there are more errors in this style.

2.8.3 works fine, i suppose?

No, i seem to have screwed up my system. Everything was working fine and then i
decided to remove the doc USE-flag and emerge -uDvNa world. But that should not
do any harm, i think.

With 2.8.3 i get:

no -inline 10 -linkall  -o svg_converter \
             unix.cmxa str.cmxa -ccopt "-Wl,-z,noexecstack " -cclib "-lz  "
-cclib -lbz2 -ccopt "-pthread" \
          \
          \
          \
          \
        -I build    
/bin/sh: no: command not found
make: *** [svg_converter] Error 127

This seems very strange, i'll attach the whole buildlog of both builds.

Created an attachment (id=115418) [details]
2.8.4 build

This is the first build, which succedes but does not produce the binaries.

Created an attachment (id=115419) [details]
2.8.3 build

this is the 2.8.3 build, that failes.

Seems your compiler is a bit broken.

As this doesn't have nothing to do with mldonkey, closing as CANTFIX.

Eh. At minimum, the ebuild should fail on failed dobin instead of installing
dummy junk without any binaries... (Yeah, Bug 138792 didn't get too far.)

The dobin-failing stuff would be nice to have, yes.

Thanks for your help. I would like to know how i broke my compiler. Damn.

Nod, fixed.

This bug may be assigned to the wrong people, but it is not fixed for me. My
gcc might be broken, but it is broken in a very strange way and i have no idea
how to fix it.

I just recompiled 4.1.1 gcc (using the broken 4.1.1 gcc, which worked) and i
still have the same error when compiling mldonkey.

Or maybe ocaml is broken, i don't know. I will try out some more. If anybody
has any idea what i could try, pleae leave a comment. Thanks.

I tried

emerge -ev mldonkey

and during this rebuilt gcc and glibc, without any problem. Just mldonkey keeps
on failing.

I only have test enabled as a USE-flag for gcc. Do i need anything else?

"       ewarn "Likewise, building with a hardened gcc is not possible.""

No Ocaml with hardened gcc, no MLDonkey without Ocaml...

Some more stuff about Ocaml and hardened environments:
http://caml.inria.fr/pub/ml-archives/caml-list/2006/11/2678e935e05e0298cc2e5352b966c262.en.html

Thanks for the links. I read the ebuild message (i think, at least) but i do
not use hardened gcc at the moment, neither hardened glibc. I wanted to switch
but my system already had gcc 4.x and glibc 2.4 and >glibc-2.3 is not supported
by hardened yet, as far as i know. I have the corresponding entries for gcc and
glibc (-hardened) in package.use.

The hardened you see is only the kernel. My profile also is not hardened, only
selinux.

Can this executable stack thing be a problem for me since i don't use hardened
gcc and glibc or might any other kernel stuff be the reason for my problems?

Should this bug be reassigned to hardened?

I have no selinux, no hardened toolchain. I only run a grsec enabled kernel.
When building dev-lang/ocaml, i get no grsec info or error messages, so no
hardened stuff does influence that build. I also noticed that i have no
ocamlopt binary afterwards. Is this normal or is this a problem?

When i build net-p2p/mldonkey, i have exactly the same problem, but also
no error or info messages from grsec.

Same problem here with mldonkey-2.8.5 after upgrading to ocaml-3.09.3 and with
a normal linux kernel (no gr, no se, no hardened)

I have the same issue. I checked inside the build directory, the executables
are created with a .byte extension. Thus dobin do not find them.

It's working now since I upgraded to 3.09.3-r1 !

Same here, i'll close the bug. If some dev wants to reopen it until the
mentioned package is stable, please do so.
