Bug 219604 – net-fs/samba-3.0.28a emake python_ext failed

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Alexey Charkov 2008-04-28 16:32:19 UTC]

After disabling the ipv6 USE-flag and rebuilding the affected packages on my ~amd64 system with GCC 4.3, I am no longer able to build net-fs/samba-3.0.28a. `USE=ipv6 emerge -1 samba` does not succeed any longer, either. My currently installed version was compiled previously with GCC 4.3, so this is probably not a GCC-related issue.

Reproducible: Always

Steps to Reproduce:

Actual Results:  
The build process fails and ends with the following line:

/usr/lib/gcc/x86_64-pc-linux-gnu/4.3.0/../../../../lib64/Scrt1.o: In function `_start':

Could you post more of the build log, please?

[Comment 2 Alexey Charkov 2008-04-28 17:05:42 UTC]

Created attachment 151256 [details]
Complete build log

There are no errors before this one, however.

[Comment 3 Alexey Charkov 2008-04-28 17:12:16 UTC]

Sorry for my non-English locale setting. The lines in Russian right before the error occurs are only warnings, not errors. They complain about incompatible pointer types, python/py_spoolss_common.c:30 stating 'incompatible pointer type in assignment' and others simply 'incompatible pointer type'.

[Comment 4 Samuli Suominen (RETIRED) 2008-04-29 13:21:10 UTC]

For what's it worth I can reproduce this, haven't looked better yet..

[Comment 5 vorfeed.canal 2008-05-07 10:21:18 UTC]

The problem is that samba issues controversial command:
gcc -pie -shared ...
What this command is supposed to build? Executable (-pie == Position Independent Executable)? Shared library (-shared == shared library, please)? gcc before 4.3 interprets it as shared library, gcc 4.3 thinks it's asked to build position independent executable.

Fixed this with dirty, dirty hack:

Don't know what is the good solution...

[Comment 6 Tiziano Müller (RETIRED) 2008-05-17 12:37:52 UTC]

Thanks for the hint.
... and there is a nice way to solve it :-) (btw, your fix didn't work here since python seems to grab also the LDFLAGS env var which is being set by the Makefile)
