Subject: [Pymilter] Adding -fPIE optoin when building sendmail srcrpm for
	RedHat 4
Message-ID: <SNT115-W56A56D18A1DF2A47924D05C3730@phx.gbl>


List,

 

I've been workign with pymilter for a few weeks now and seem to have things worked out on Fedora 11.  Now, I'm running into problems when trying to install pymilter-0.9.3 on Red Hat EL4 x86_64.  I get the follwoing error when trying to install:

 

gcc -pthread -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -fPIC -DMAX_ML_REPLY=32 -I/usr/local/include/python2.4 -c miltermodule.c -o build/temp.linux-x86_64-2.4/miltermodule.o
gcc -pthread -shared build/temp.linux-x86_64-2.4/miltermodule.o -L/usr/lib/libmilter -lmilter -o build/lib.linux-x86_64-2.4/milter.so
/usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/3.4.6/../../../../lib64/libmilter.a(listener.o): relocation R_X86_64_PC32 against `mi_opensocket' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status
error: command 'gcc' failed with exit status 1


I noticed the mailing list entry from August regaurding the issue installing on CentOS 5 but I am unable to figure out how to mofify the src rpm .spec file so that sendmail will complie with the -fPIE option.  I tried to change the following lines in the .spec file as shown below:

 

%if "%{enable_pie}" == "yes"
%ifarch s390 s390
%define _fpie -fPIE
%else
%define _fpie -fPIE
%endif


so that _fpie is always set to -fPIE.  I've also made sure that the enable_pie variable is set to "yes".  Any help you can provide would be appreciated.

 

Thanks,

You probably don't want to set sendmail to PIE in general.  Only libmilter 
is the problem.  Here is the patch I added to CentOS5 for sendmail-8.14.3 
on x86_64:

$ cat sendmail-8.14.3-x86_64.patch
diff -up ./libmilter/Makefile.m4.bms ./libmilter/Makefile.m4

The packager of sendmail envisioned static C milter applications linking
against libmilter, and optimized for that.  Pymilter, as a python extension, is
a dynamic library, and libmilter must be compiled appropriately.  This should
not hurt static C milters (other than being ever so immeasurably slightly
slower).

Stuart,

 

Thanks.  I've got my milter working.  For future reference I'm using RHEL 4 x86_64.  I order to get the pymilter working I added the following line to the ./libmilter/Makefile.m4 file: 

 

define(`confOPTIMIZE', `-O2 -g -m64 -fPIC')

 

I had to remove the mtune option in order to patch sendmail and recompile the src rpm successfully.  Thanks for responding so promptly.  I appreciate your work on the pymilter module.  

 

Thanks,

 

Kyle Oetken
