In this how-to, we'll outline how to install a fresh exim binary for your system. For compatibilities reasons, we'll make this a non-static binary, as since it's compiled right on your own system, you won't have any library issues.
We'll use exim 4.71 for this example. Change all occurances of 4.71 to the version you want to use.
wget http://files.directadmin.com/services/custombuild/exim-4.71.tar.gz tar xvzf exim-4.71.tar.gz cd exim-4.71/Local wget http://www.directadmin.com/Makefile perl -pi -e 's/^EXTRALIBS/#EXTRALIBS/' Makefile perl -pi -e 's/HAVE_ICONV=yes/HAVE_ICONV=no/' Makefile cd .. make make install
This will give you a new /usr/sbin/exim-4.71-1 binary which won't be what you want.. you'll need to rename it to /usr/sbin/exim:
cp -f /usr/sbin/exim-4.71-1 /usr/sbin/exim chmod 4755 /usr/sbin/exim
Remember to restart exim after you're finished.
**Note: If you can't download the exim-4.71.tar.gz from the above link, just go to www.exim.org and find a different link there. It's the original source, unmodified by us, you can get it anywhere.
You may need to edit the Local/Makefile and remove the iconv section near the top: HAVE_ICONV=no if you see this error
rfc2047.o: In function `rfc2047_decode2': rfc2047.c:(.text+0x395): undefined reference to `libiconv_open' rfc2047.c:(.text+0x45a): undefined reference to `libiconv' rfc2047.c:(.text+0x539): undefined reference to `libiconv_close'
For all OS's, you'll also need db4 dev, so type the following on debian
apt-get install libdb4.6-dev libperl-dev
or rpm systems:
yum install db4-devel
If you get perl errors during the compile, you may need to edit the Local/Makefile, and set the values for: PERL_CC, PERL_CCOPTS, and PERL_LIBS.
You can generate the values for those options with the following code:
echo "PERL_CC=`/usr/bin/perl -MConfig -e 'print $Config{cc}'`"
echo "PERL_CCOPTS=`/usr/bin/perl -MExtUtils::Embed -e ccopts`"
echo "PERL_LIBS=`/usr/bin/perl -MExtUtils::Embed -e ldopts`"
Sample values for FreeBSD 7:
PERL_CC=cc PERL_CCOPTS= -DAPPLLIB_EXP="/usr/local/lib/perl5/5.8.8/BSDPAN" -DHAS_FPSETMASK -DHAS_FLOATINGPOINT_H -fno-strict-aliasing -pipe -Wdeclaration-after-statement -I/usr/local/include -I/usr/local/lib/perl5/5.8.8/mach/CORE PERL_LIBS= -Wl,-R/usr/local/lib/perl5/5.8.8/mach/CORE -Wl,-E -L/usr/local/lib /usr/local/lib/perl5/5.8.8/mach/auto/DynaLoader/DynaLoader.a -L/usr/local/lib/perl5/5.8.8/mach/CORE -lperl -lm -lcrypt -lutil
Sample values for Debian 4:
PERL_CC=cc PERL_CCOPTS= -D_REENTRANT -D_GNU_SOURCE -DTHREADS_HAVE_PIDS -DDEBIAN -fno-strict-aliasing -pipe -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/lib/perl/5.8/CORE PERL_LIBS=-Wl,-E -L/usr/local/lib /usr/lib/perl/5.8/auto/DynaLoader/DynaLoader.a -L/usr/lib/perl/5.8/CORE -ldl -lm -lpthread -lc -lcrypt
On debian, if you're missing any requird modules, without actually installing “exim4”, you can use:
apt-get build-dep exim4
to install all dependancies that exim needs to compile, without installing the apt-get version of exim itself.
Debian 5 requires the libperl5.10 module. If you don't have it:
apt-get install libperl5.10
The above code will resolve the error:
exim: error while loading shared libraries: libperl.so.5.10: cannot open shared object file: No such file or directory
