How to create postfix rpm from source - centos

I need/want to upgrade postfix from 2.11.6 to 2.11.11 on CentOS 6.7
the current 2.11.6 version is installed as RPM, and I need to find / create postfix 2.11.11 rpm so that I can use it on multiple machines for the upgrade.
I only found SRPM from SuSE for 2.11.11 and I tried to extract the SRPM and build it with the rpmbuild command but it fails with many errors so I guess its not possible to do it like that out of the box.
I also tried to build my own RPM from the postfix source code available on their website:
Postfix 2.11.11 source code
However creating a spec file from scratch is a bit too much for me and I'm not even certain if what I'm doing is correct or if it will break my current postfix installation if I attempt to upgrade it with my custom rpm.
So in short,
I need to create postfix 2.11.11 RPM so I can use it to upgrade my current postfix on multiple machines and I cannot find/don't know how to create a valid rpm.

Create a virtual machine similar to your server and build your rpm there. Check this out this
https://www.thegeekstuff.com/2015/02/rpm-build-package-example.
Or this
http://lifeofageekadmin.com/build-rpms-centos/
I havent compile postfix in ages so I dont remember what params you might need so read this
http://www.postfix.org/INSTALL.html, be sure to add support for the stuff you use. It is probably going to be trial an error.
Dont compile nothing on a production server, you should never have compiling tools on it. Do everything on your virtual machine.
This might help you find out what options were used to compile your previous version of postfix: https://unix.stackexchange.com/questions/134914/how-do-i-determine-which-configuration-options-an-rpm-package-is-built-with.
I found this too
https://www.digrouz.com/mediawiki/index.php/HOWTO_Rebuild_a_RPM_from_sources_with_specific_application_support

You can check on build system of suse.
https://build.opensuse.org/search?name=1&package=1&project=1
There are some package available for postfix, some are for centos...
that could be a good start.
You create start your own package too from this site.

Variant Effect Predictor | DBD mysql failing to setup

I trying to get set up with Variant Effect Predictor (VEP) on the command line. I'm following the setup tutorial but I'm encountering some errors around dependencies. I'm also quite new to the command line so if anyone is able to break down the solution too then I'd be very grateful. Thanks!
Tutorial: https://www.ensembl.org/info/docs/tools/vep/script/vep_tutorial.html
VEP requirements: http://www.ensembl.org/info/docs/tools/vep/script/vep_download.html#requirements
I also have Perl v5.32.1.
What I've done:
I installed dependencies (listed in the requirements page) with the following commands:
- sudo -s cpanm DBI
- sudo -s cpanm Archive::Zip
- sudo -s cpanm DBD::mysql
For DBD:mysql, I got the follwoing message:
--> Working on DBD::mysql
Fetching http://www.cpan.org/authors/id/D/DV/DVEEDEN/DBD-mysql-4.050.tar.gz ... OK

! Configure failed for DBD-mysql-4.050. See /root/.cpanm/work/1626111140.5937/build.log for details.
Trying it out anyway, I ran perl INSTALL.pl (from the tutorial page) and got the message below. I would like VEP to run in online mode too if possible.
`WARNING: DBD::mysql module not found. VEP can only run in offline (--offline) mode without DBD::mysql installed

You show us this error:
Configure failed for DBD-mysql-4.050. See /root/.cpanm/work/1626111140.5937/build.log for details.
So looking in there will give you more clues about what the problems are. Without that, we can only guess.
But we can make educated guesses. The DBD::mysql distribution comes with a file called DBD::mysql::INSTALL which will talk you through some of the problems you'll find while installing this module.
It's important to note that DBD::mysql is a wrapper around MySQL's client libraries. They are written in C, so you'll need a C compiler installed in order to build DBD::mysql. You'll also need the client libraries and the development versions of the client libraries (for the C header files that you'll need to compile the module). On Ubuntu, those packages are called "libmysqlclient" and "libmysqlclient-dev". If you don't have a C compiler, then you'll want to install "gcc" too.
But this is all getting a bit complicated. There's another, simpler, approach. If you're using the system version of Perl (the version that was installed as part of the operating system and probably lives in /usr/bin/perl) then I'd recommend using the pre-build Ubuntu version of the package, which you can install by running:
$ sudo apt-get install libdbd-mysql-perl
Installing that version uses the OS's own package manager, and the package manager knows which other packages are needed in order for it to work - so it will install those as well.
People will probably complain that you're better off installing the modules from CPAN as it gives you more flexibility and allows you to use more up-to-date packages than the versions from your OS repos. And they're right. But, honestly, if you're a non-Perl programmer who just wants to get an application up and running, this is by far the simplest approach.
(But, as I said above, this is all guesswork as you haven't shared the most important errors with us.)

"No package provides libsystemd.so.0(LIBSYSTEMD_219)" during do_rootfs

I'm attempting to build an image with the phytec bsp 18.2 from here: https://wiki.phytec.com/productinfo/phycore-i-mx7/bsp-yocto-fsl-imx7/
I require a newer version of systemd (> 234) and so am substituting the systemd recipe for version 234 from rocko, found here: http://cgit.openembedded.org/openembedded-core/tree/meta/recipes-core/systemd?h=rocko by putting this in a custom layer. However, during the do_rootfs step, I receive an error that "No package provides libsystemd.so.0(LIBSYSTEMD_219). I've tried a work-around recommended here: Smart can't install...no package provides shared object file and it didn't solve the issue. I've tried echoing libsystemd.so.0, LIBSYSTEMD_219, and libsystemd.so.0(LIBSYSTEMD_219) to both ${rootfs}/etc/rpm/sysinfo/Providename and ${rootfs}/var/lib/rpm/Providename and had no luck. Does anyone have an idea on how to fix this? I'd appreciate any help that could be offered, and please let me know if I can offer any more information.
I don't know about the yocto wrapper, etc, but in standard RPM-land, this error:
Computing transaction...error: Can't install python3-systemd-234-r0.0#cortexa7hf_neon: no package provides libsystemd.so.0(LIBSYSTEMD_219)
means that there is a .so or executable in the RPM named python3-systemd-234-r0.0 that was compiled with a specific version of libsystemd.so.0 that had the flag LIBSYSTEMD_219. That flag is the "ELF Symbol Versioning" and it's seen most with GLIBC_XX when you try to install an RPM that's too new for a target system (e.g. CentOS 7 RPM on CentOS 6).
The systemd on your target machine is too old, so it only defines the versions it is compatible with, e.g. libsystemd.so.0(LIBSYSTEMD_210) or similar.
What you need to do is build your python3-systemd-234-r0.0 on a machine with the same version of systemd as the target (or cross-compile appropriately), or create a systemd RPM that includes the functionality you're attempting.
So you need to figure out how to apply one of these solutions to your build system; sorry I don't know enough about yocto to help there.

Compile quickfix without mysql

I want to compile quickfix library, I don't have any MySQL installed on my computer and it is not necessary for me. I tried to disable the mysql from the configure --without-mysql but when I compile, I still see -lmysqlclient in my compiling command and it eventually fails because I don't have this library file. How can I disable this?
Also, if I tried to compile with old gcc4.1.2 (newer version like 4.8 is fine), but I cannot even generate the configure file but keeps seeing this error:
configure: error: unable to find set_terminate in std or global namespace
There should be any problem with this compiler because I can compile many other things and I have to use this version of the compiler because many of my libraries are compiled under this version.
I assume, you want to compile C++ source codes - http://www.quickfixengine.org/quickfix/doc/html/building.html. The tutorial indicates that MySQL is optional. To install MySQL support, you need to explicitly add --with-mysql flag. There is not --without-mysql flag.

Problems installing/compiling DBD::mysql on OpenSuSE 10

I am getting a bunch of compile errors when I try to install the MySQL DBD::mysql Perl library. I am trying to install this library on OpenSuse linux (SUSE Linux Enterprise server 10 (x86_64) version 10, patch level 4)
The install fails when trying to compile dbdimp.h. There are hundreds of complile errors but I have reason to believe they all stem from the first 3:
dbdimp.h:23:49: error: mysql.h: No such file or directory
dbdimp.h:24:45: error: mysqld_error.h: No such file or directory
dbdimp.h:26:49: error: errmsg.h: No such file or directory
I believe that the reason I am getting the errors above is that I have no MySql Client installed. I do not know how to install mysql client (I believe I am supposed to get some version of libmysqlclient).
I am brand new to opensuse and vaguely familar with installing packages on Linux in general have used yum, yast, apt-get on ubuntu + centOS previously but the only package manager tools that seem to be on OpenSuse 10 are rpm and zypper. I have not managed to install the required mysql client using either of these. If anyone knows how to install MySql Client to resolve my issue I would greatly appreciate any recomendations
Thanks
You need to install MySQL or the MySQL client libraries, either through your system's package manager or by following the installation instructions from the source code.
It sounds like your question is really "How do I install MySQL on OpenSuse", which would be more appropriate for one of the other StackExchange sites.
I was able to resolve this to a point. In my original question, I stated that I had tried using YAST but that it had not worked. In fact, I did not fully explore the YAST install option but when I did, I managed to download install the required librarys by following an article I found (http://adminramble.com/install-mysql-yast/#chitika_close_button)
I was able to open the YAST GUI in the terminal window (not an X-window display) and navigate through the "software management" section wherein I was able to do a search for MySql. Amoung the search results were mysql client libraries, which I then selected and hit "Accept". The installation started and completed successully.
In order to complile the PERL DBD::mysql module, I had to create a new makefile with the ccflags specified so that the header files could be found:
perl Makefile.PL --cflags -I/usr/include/mysql
I say "to a point" at the top of this comment because I then ran into further problems compiling but my original issue posted has been partially resolved and getting this far may help someone else who is experiencing the same problem. Will update if I get a solution to the compile problem.

How do I enforce RPM requires order

I have spent all day trying various things and made no progress whatsoever.
I am compiling an rpm package for my application (MyApp.rpm), for RHEL6 64-bit, which requires a third party, 32-bit driver package called aksusbd.rpm. Now, aksusbd.rpm in turn requires compatibility mode, provided on RHEL6 by glibc.i686.rpm.
So somewhere in my spec file for MyApp.rpm I have:
MyApp.spec
Requires: glibc(x86-32)
Requires: aksusbd >= 1.14
What it does during installation (yum install MyApp) is, installs aksusbd first, which fails with no 32-bit compatibility installed. Then just to tease me, immediately after installs glibc. So when its all over I can type
yum install aksusbd
and it works this time because glibc is now installed.
How on earth do I teach it to do better than this!
(growl)
You can follow Aaron's suggestion and tweak the third party RPM you have with rpmrebuild. It allows you to modify the requires spec of the RPM package:
rpmrebuild --package -n --edit-requires <your third party rpm package>
It's a hack but just for the requires tags in the RPM I would not be concerned.
First off I'd suggest putting the requires on the same line. Just separate them with a comma, they should then go in the order you've specified. If it doesn't and you're on RPM version 4.3 or below, you can use the PreReq tag as specified in the rpm.org docs about half way down the page.
If neither of those solutions works, or you are on a version of RPM greater than or equal to 4.4 I would imagine something else is going on that is causing a problem. I'd start by creating a new spec for some 'fake' project that specifically targets the issue of glibc not being installed before aksusbd. If that works we know it's something with your MyApp.spec, if it doesn't work then I'd suggest reviewing the naming convention of glibc, perhaps there is some kind of issue with how it's interpreting your (x86-32).
Sounds like the aksusbd RPM is what needs to be fixed - they need a Requires or Requires(pre) set. File a bug with the driver vendor.
I had exactly the same problem (and same in YUM groups). If Forrest suggestion to put requires in same line works for you, please let us know.
Otherwise, you can try to add an RPM that only requires aksusbd and add it to requires list. If YUM installs dependencies in an Alpha-beta order, name it something between aksusbd and glibc and it might work.
