Having exactly the same problem...
I need libmysqlclient to install the root library (by CERN)
Is there a fast workaround that I can do to make it work? (Unfortunately I'm not really familiar with cmake, so I couldn't help myself on that one)
The only thing that I found is to open /usr/include/boost/version.hpp and change the version during installation. However that doesn't seem right even for a workaround. It compiles, but I'm not sure yet if it really works.
It would be really nice if you could submit a patch.
Update: okay it fails to compile.
/usr/include/boost/geometry/util/has_non_finite_coordinate.hpp:42:12: error: ‘has_coordinate_with_property’ is not a member of ‘boost::geometry::detail’
return detail::has_coordinate_with_property

Seems that mysql really need that old version of boost.

Hi folks
It seems to me MySQL is quite strict on the version of boost. I failed installing with following error:
```
-- Found /usr/include/boost/version.hpp
-- BOOST_VERSION_NUMBER is #define BOOST_VERSION 106000
CMake Warning at cmake/boost.cmake:256 (MESSAGE):
Boost minor version found is 60 we need 59
Call Stack (most recent call first):
CMakeLists.txt:435 (INCLUDE)
-- BOOST_INCLUDE_DIR /usr/include
-- LOCAL_BOOST_DIR
-- LOCAL_BOOST_ZIP
-- Could not find (the correct version of) boost.
-- MySQL currently requires boost_1_59_0
CMake Error at cmake/boost.cmake:76 (MESSAGE):
You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=<directory>
This CMake script will look for boost in <directory>. If it is not there,
it will download and unpack it (in that directory) for you.
If you are inside a firewall, you may need to use an http proxy:
export http_proxy=http://example.com:80
Call Stack (most recent call first):

CMakeLists.txt:435 (INCLUDE)
-- Configuring incomplete, errors occurred!
See also "/tmp/yaourt-tmp-tle/aur-mysql/src/build/CMakeFiles/CMakeOutput.log".
```
As you can see above the version that MySQL asked for is minor 59, whilst I have 60. I am more than happy to submit a patch if no one's up for it.

Postfix won't start after the upgrade to mysql-5.7: "postfix: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory"
Muflone commented on 2015-11-01 23:46 (UTC)
Updated to version 5.7
version 5.6 users could move to the mysql56 package

libjemalloc.so.1: cannot open shared object file
it need rebuilding ..
Marcel_K commented on 2015-07-30 13:43 (UTC)
I had no problem downloading from that location, although another issue popped up: there is no GPG signature at dev.mysql.com, only at cdn.mysql.com. If you change the first line in the source array and add a validpgpkeys entry like
validpgpkeys=('A4A9406876FCBD3C456770C88C718D3B5072E1F5')
source=("https://cdn.mysql.com/Downloads/MySQL-5.6/${pkgbase}-${pkgver}.tar.gz"{,.asc}
the tarball is checked for being genuine, too.
lucc commented on 2015-07-30 13:23 (UTC)
Is it possible that the upstream website does not support the https links in the PKGBUILD? I had trouble opening the website or downloading the tarball until I removed the "s".

@nicolascevallos
use pactree (and pactree -r) to discover why your installation requires you to install mysql-connector-c.
The forum is the best way to try to solve your issues.
I cannot help you as the issue doesn't seem related in any way to any of my packages.
nicolascevallos commented on 2014-12-23 17:59 (UTC)
Muflone, thanks for your response.
I downloaded the last shared component in a rpm file from http://dev.mysql.com/downloads/mysql/ and I see that the file of libmysqlclient.so is libmysqlclient.so.18.1.0 and it is different from the last version of Connector/C (libmysqlclient) package in http://dev.mysql.com/downloads/connector/c/
As in my last message of mysql-connector-c package, I don't know why mysql-connector-c need an update if it's not installed :(
And I don't understand why mysql-connector-c needs libmariadbclient/libmysqlclient.
Please, notify me if I can do something to help! :)
Muflone commented on 2014-12-23 16:02 (UTC)
Indeed the package mysql is out of date, a new 5.6.22 version was released a couple of days ago [1]. I'll update this package very soon after a short test.
However about the conflicting files there's nothing that I can do. The package libmysqlclient provides the libmysqlclient library, and the mysql-connector-c packages provides its copy of libmysqlclient, then the two packages conflicts.
I think the mysql-connector-c package shouldn't provide its copy of the libmysqlclient library or if it must have such version, then it should be installed in a dedicated folder. Obviously the same applies also to all the other similar conflicting files.
The final option would be that mysql-connector-c applies a conflicts options in the PKGBUILD to avoid conflicting files and then avoiding that both mysql and mysql-connector-c would be installed together.
