Dependencies of packages

[madurani]

Hello All,

The firs question:
How can I find out, that which package from /var/lib/portage/world pulled installation of some installed package which missing in world file?
For example I have installed MariaDB and it missing in /var/lib/portage/world. I want known via which package it was installed.

The second question:
I tried manually compile mysql(not via emerge) and make crashed on missing command rpcgen. This binary file in Oracle-Linux is reachable via packade glibc-common.rpm, but in gentoo I don't know find it. Do you have some idea how I can install rpcgen in gentoo?

You can use app-portage/gentoolkit

rpcgen should be part of glibc, which I am pretty sure you have installed

Hello All,

Yes, glibc is installed , but command rpcgen missing :

argo ~ # emerge -av glibc

Might be time to re-emerge glibc with the above command (minus the -p).

Also, why do you feel the need to manually build mysql?

Glibc from your Gentoo is in version 2.25 and USE flag rpc exist there, but in my case is version 2.26 and rpc flag missing.
I tried downgrade it to some older version. Rpc flag there exist, but there is big dependencies affect to other packages

[madurani]

I want install mysql or mariadb to other location. Manual compilation of mysql still crashed. Is some possibility to install via emerge mariadb to other as default location? I need to change flag -DCMAKE_INSTALL_PREFIX=/usr to some other location.

[madurani]

I downloaded mariaDB source and a manual compilation finish success.

Ok, to clear this up on rpc wise; glibc-2.26 and later does NOT provide rpc anymore, earlier versions still provide it...

For more information, here's the dev's message thread about this
https://archives.gentoo.org/gentoo-dev/ ... 4daf2c7ce8
(glibc-rpc) - [TRACKER] Packages failing to build with no rpc in sys-libs/glibc

In short, we need to install a library that provides the rpc, in the message thread, it recommends net-libs/libtirpc. Now it also mentions net-libs/rpcsvc-proto may also be needed, but for me only libtirpc was pulled in for sure. For me, I did install rpcsvc-proto in case anyways, so I don't have an issue.

Note: From what I saw doing a search, rpc was discountinued from glibc 2.14, but Gentoo provided a workaround til now...

I want install mysql or mariadb to other location.

Why do you need to install it to an unusual location? What problem are you trying to solve by doing this?

[madurani]

I want install/compile Apache+PHP+MyPhpAdmin+MySQL+Java+Eclipse+Javafx_scenebuilder+Mysql-connector to some isolate volume. In my case to /svc/opt.
I know, that most of mentioned packages are reachable via emerge, but in this case will installed to path as /usr, /opt or some other(will be lost in system). And when will be in portage new version so will be upgraded.
I want mentioned applications undepended on OS.

I installed both of packages, but make don't know find one file rpc/rpc.h. This file is included in:

net-libs/libtirpc-1.0.2-r1 (/usr/include/tirpc/rpc/rpc.h)

Can I add path to mentioned file to some variable which is use during compilation?

Probably I found some solution with GLIBC-RPC issue, but not look very good
I did some change in folder /usr/include:
1: I renamed existed empty folder rpc to rpc1
2: then I created some symbolic link as:

Code: Select all

argo /usr/include # ls -la | grep rpc
lrwxrwxrwx   1 root root     30 Jan 24 21:45 netconfig.h -> /usr/include/tirpc/netconfig.h
lrwxrwxrwx   1 root root     22 Jan 24 21:48 rpc -> /usr/include/tirpc/rpc
drwxr-xr-x   2 root root   4096 Jan 24 21:47 rpc1

argo /usr/include/rpc
netdb.h -> /usr/include/netdb.h

Now compilation of mysql continue. I hope that finis properly.

Manual compilation of last stable MySQL-5.7.21 finish success

Look that work fine:

Next topic: manual compilation of PHP with MySQL dependencies

There is one flag:
--with-mysqli=/svc/opt/mysql/bin/mysql_config'
When I compile PHP with it, then is there problem with library mysqlclient_r in MySQL(not exist). It missing in new MySQL release 5.7.x. Older release as 5.6.x and 5.5.x have include it and there isn't any problem.
When I use this flag without path to mysql_config only as " --with-mysqli", then compilation finish successfully. And it looks, that PHP+Apache+phpMyAdmin works fine. I can via phpMyAdmin join to DB and manage it.

Question:

1:Does anybody knows, whether exists some config flag in MySQL for building this library, or it is some additional source code to MySQL for building it?

2: Is there any difference in functionality of PHP, when build is with "--with-mysqli=/svc/opt/mysql/bin/mysql_config" or only with "--with-mysqli"?

I need to upgrade(manually compiled) MySQL to higher version(because of vulnerability issue), but I can't switch to 5.7.x version of MySQL, because PHP and dependence of missing library:
