Bug 110278 – Samba binaries fail to execute because they get compiled as shared objects.

• Product: Gentoo/Alt
• Status: RESOLVED FIXED

[Description Javier Villavicencio (RETIRED) 2005-10-23 16:09:35 UTC]

On FreeBSD it seems that the compiler flag -pie used when linking some of the
executables, creates a shared object binary:

[/ #] file /usr/bin/smbclient
/usr/bin/smbclient: ELF 32-bit LSB shared object, Intel 80386, version 1
(FreeBSD), for FreeBSD 5.4, stripped

which should be something like:
[/ #] file /usr/sbin/smbd
/usr/sbin/smbd: ELF 32-bit LSB executable, Intel 80386, version 1 (FreeBSD), for
FreeBSD 5.4, dynamically linked (uses shared libs), for FreeBSD 5.4, not stripped


Reproducible: Always
Steps to Reproduce:
1.emerge net-fs/samba
2.try to run one of the distribution programs, ie: /usr/bin/smbclient


Actual Results:  
[/ #] smbclient
-/bin/bash: /usr/bin/smbclient: cannot execute binary file


Expected Results:

I've added a simple check to gentoo-alt overlay's ebuild that tests the CHOST used.
Can you give that a try and see if that works?

[Comment 2 Javier Villavicencio (RETIRED) 2005-10-25 06:34:22 UTC]

Still links the binaries with -pie as 

[/usr/local/portage #] file /usr/sbin/smbd
/usr/sbin/smbd: ELF 32-bit LSB shared object, Intel 80386, version 1 (FreeBSD),
for FreeBSD 5.4, stripped

And, because of that:
[09:44:11]
[/usr/local/portage #] smbclient -L //192.168.0.1/
-su: /usr/bin/smbclient: cannot execute binary file

[Comment 3 Javier Villavicencio (RETIRED) 2005-10-25 06:41:49 UTC]

Just trying again to see the error:

/usr/local/portage/gentoo-freebsd/net-fs/samba/samba-3.0.20b.ebuild: line 106:
--with-expsam=pgsql, --with-manpages-langs=en --without-ldapsam --with-winbind
--with-shared-modules=idmap_rid --disable-pie: command not found

in that line:
[[ ${CHOST} == *-*bsd* ]] && "${myconf} --disable-pie"

and it should be
[[ ${CHOST} == *-*bsd* ]] && myconf="${myconf} --disable-pie"

[Comment 4 Diego Elio Pettenò (RETIRED) 2005-10-25 07:05:33 UTC]

Okay, I should *not* try to get things done without sleep, does it work after 
fixing the ebuild? 

[Comment 5 Javier Villavicencio (RETIRED) 2005-10-25 10:21:12 UTC]

Emerges fine, works fine:

Moving that to samba team :)

Created attachment 71618 [details, diff]
samba-nopie.patch

Here is the patch that works (currently on gentoo-alt overlay). Is okay if I
commit it?

[Comment 8 Christian Andreetta (RETIRED) 2005-10-28 06:03:51 UTC]

good work doesn't need permission: go ahead :-)

[Comment 9 Diego Elio Pettenò (RETIRED) 2005-10-29 04:10:30 UTC]

Thanks, I've committed it now.
