Gentoo ERROR: Python module pytevent of version 0.10.2 not found, and bundling disabled

Emerging the sys-libs/ldb-2.3.0-r1 package may fail with an error for a missing Python mode, despite the sys-libs/tevent with a python USE flag is presented in the system:

Checking for system tevent (>=0.10.2)                                                           : yes 
ERROR: Python module pytevent of version 0.10.2 not found, and bundling disabled
 * ERROR: sys-libs/ldb-2.3.0-r1::gentoo failed (configure phase):
 *   configure failed
 * 
 * Call stack:

Indeed, the tevent (>=0.10.2) is found, but not the Python module! And the checking pase of the setup fails.
First, check whether the USE of sys-libs/tevent has python and the right version PYTHON_SINGLE_TARGET=”python3_8″ is used (the Python version may vary here):

root@srv # emerge -pv =tevent-0.10.2::gentoo

[ebuild   R    ] sys-libs/tevent-0.10.2::gentoo  USE="python" ABI_X86="32 (64) (-x32)" PYTHON_SINGLE_TARGET="python3_8 -python3_9" 0 KiB

Total: 1 package (1 reinstall), Size of downloads: 0 KiB

This system uses Python 3.8 and the library sys-libs/tevent was built with this USE flag.

The problem here is the tevent is installed under a its own directory: /usr/lib64/tevent. Using the ldconig utility the problem quickly has been resolved. Just add a file /etc/ld.so.conf.d/tevent_ldb.conf with the path to the library and then regenerate the ldconfig:

root@srv # cat /etc/ld.so.conf.d/tevent_ldb.conf
/usr/lib64/tevent
root@srv # ldconfig
root@srv # 

Do not forget to run the “ldconfig“, because tevent library won’t be added to the LD cache. Emerging the sys-libs/ldb and then samba was successful after this quick workaround! There is a Gentoo bug reported, but the problem still exists – https://bugs.gentoo.org/590026

Gentoo emerge virtualbox- Mesa / GLU: Mesa not found at, Mesa headers not found

Emerging the package app-emulation/virtualbox the following error occurs:

The configure script reports the mesa is missing, but the package media-libs/mesa is installed. Reinstalling does not fix the problem.
Farther investigation in the logs by checking the configure.log reveals the real problem:

      |          ^~~~~~~~~~
compilation terminated.

The glu part of mesa is missing. In Gentoo, the glu (https://gitlab.freedesktop.org/mesa/glu) is not included in the media-libs/mesa and it is a separate package media-libs/glu.

The solution is to emerge media-libs/glu and then the app-emulation/virtualbox.

emerge -v media-libs/glu

Another Linux distribution may include glu in the main mesa package.

Here, the conclusion is to always check the configure.log, because it reports the exact error and not to trust the generic output of the configure script.

Gentoo emerge GO lang failed – atomic_amd64x.go: too many errors

Upgrading GO lang under Gentoo maybe a little bit tricky. The upgrading go lang from 1.13.7 to 1.15.5 failed with strange error:

Googling a little bit and it appeared there might be a conflict with the old version in the same directory. Deleting the temporary build directory didn’t help…

Removing the GO lang package by unmerge command and then emerging the newest GO lang package is successful.

So the solution is to unmerge it and then immediately emerge the newest version with:

emerge -vC dev-lang/go
emerge -v dev-lang/go

gentoo network interface with hyphen in the name

Using the OpenRC (i.e. init system) and network names with special symbols like hyphen in the name may lead to errors of “command not found” and “No such file or directory

The hyphen in the network interface name must be replaced in the configuration file with an underline and the init name file should be with the hyphen.

Proper configuration for network interface name with hyphen mv-eth0

  • In the configuration file /etc/conf.d/net:
    config_mv_eth0="
    192.168.0.202/24
    "
    routes_mv_eth0="
    default via 192.168.0.1
    "
    
  • The network interface init file is with hyphen:
    root@srv /etc/init.d # ln -s net.lo net.mv-eth0
    

And starting the network is successful:

root@srv ~ # /etc/init.d/net.mv-eth0 start

Virtualization software may include to the network interface name not so typical alphabets. For example, systemd-nspawn will give name to the guest’s macvlan network with mv-{host_network_name} and iv-{host_network_name} for ipvlan.

Wrong configuration with a hyphen in the network interface name.

The configuration file /etc/conf.d/net:

config_mv-eth0="
192.168.0.202/24

routes_mv-eth0="

Patch and resume compilation of a failed package in Gentoo – ebuild, local repository or ctrl+Z

A dependency package failed to compile throwing error and existing the emerge of a queue with a hundred and more packages. Or worse you installed a new version of a package and multiple rebuilds are pulled, but one of the dependencies fails and you may end up with a broken system? What can you do? There is no new version of the failed package and yes, there is a bug in the Gentoo’s Bugzilla – https://bugs.gentoo.org/. And there is a solution with a patch, which has not made its way to the production and in Gentoo portage yet.
The package in the portage is broken, no new fixed package is released, but there is a patch to fix your issue. Here is what you can do:

  • Make your own package with the fixed version of the original package and put it in your local repository (not the official one, because on every emerge –sync it will be deleted). You should make a local repository and put the ebuild and all necessary files.
  • Or just download the patch and patch the source in the directory, which still holds the source of the failed package and resume the compilation manually. Then install it. Using this tutorial – Resume installation after a package build error, when emerging firefox under Gentoo
  • Just after the uncompress operation of the emerge press CTRL+Z to put the operation in the background and download and patch. Then bring back the emerge from the background with “fg” command.

The second and third options are not permanent solutions, but they are fast enough to be used in some situations.
Here are steps for the first and second option you may have:

OPTION 1) Make your own package.

Create a local repository (for details Simple steps to create Gentoo custom repository and add a package):

root@srv ~ # mkdir -p /var/db/repos/my-local-portage/{metadata,profiles}
root@srv ~ # cat  << 'EOF' > /var/db/repos/my-local-portage/metadata/layout.conf
masters = gentoo
auto-sync = false
EOF
root@srv ~ # cat  << 'EOF' > /etc/portage/repos.conf/my-local-portage.conf
[my-local-portage]
location = /var/db/repos/my-local-portage 
EOF
root@srv ~ # cat  << 'EOF' > /var/db/repos/my-local-portage/profiles/repo_name
my-local-portage
EOF

Copy the ebuild file of the package you want to modify in the custom repository directory created above (it’s a good idea to copy all the sub-directories, too):

Simple steps to create Gentoo custom repository and add a package

Creating a custom repository would give you a chance to fast edit (ebuild) files of existing packages and drop better versions to the custom repository, which then will be used to install in the system. Here is the simplest way to create a Gentoo custom repository without installing any mandatory software. You may check the two Gentoo articles on the subject – https://wiki.gentoo.org/wiki/Custom_repository, which uses repoman (and additional software to install) and https://wiki.gentoo.org/wiki/Handbook:AMD64/Portage/CustomTree#Defining_a_custom_repository, which is part of a bigger article and without a clear example with a package as we are going to show.
Our custom repository name is “my-local-portage”.

STEP 1) Create the directories and basic configuration files for the new custom repository

Just two mandatory directories.

mkdir -p /var/db/repos/my-local-portage/{metadata,profiles}

The minimal configuration in two files:

cat  << 'EOF' > /var/db/repos/my-local-portage/metadata/layout.conf
masters = gentoo
auto-sync = false
EOF
cat  << 'EOF' > /var/db/repos/my-local-portage/profiles/repo_name
my-local-portage
EOF

Fix the permissions

chown -R portage:portage /var/db/repos/my-local-portage

The custom repository is set up. Now only the emerge should get the configuration to check for it in the next step.

STEP 2) Portage global configuration.

Add a file pointing for your custom repository in the Portage global configuration directory “/etc/portage”:

cat  << 'EOF' > /etc/portage/repos.conf/my-local-portage.conf
[my-local-portage]
location = /var/db/repos/my-local-portage
EOF

STEP 3) Add a package in the new custom repository.

The package version may be the same version as in the official Gentoo repository, but the package form the custom repository will be used if no repository is included in the “emerge” command.
For simplicity, we are going not to modify the ebuild file of a copied official package, but the idea is to copy an existing ebuild file and then change it for the user’s needs and the steps are the same as follow.
Just copy the file (and edit it). The package “app-text/calibre” was randomly selected for the example.

mkdir /var/db/repos/my-local-portage/app-text/calibre
cp /usr/portage/app-text/calibre/calibre-4.9.1-r1.ebuild /var/db/repos/my-local-portage/app-text/calibre/

Create the manifest files and you are ready:

cd /var/db/repos/my-local-portage/app-text/calibre/
ebuild calibre-4.9.1-r1.ebuild manifest

>>> Creating Manifest for /var/db/repos/my-local-portage/app-text/calibre

Fix the permissions with

chown -R portage:portage /var/db/repos/my-local-portage

The manifest file contains the hash of the ebuild file and all the additional files if any (for this package there are no additional files). All file needed for the operation will be downloaded so they must be network accessed in the time of executing the command (except in the cases when they have already existed in the distfiles directory and/or the subdirectories of the /var/db/repos/my-local-portage/app-text/calibre)

more than the default 4 parallel processes using distributed compiling with distcc

Distributed compilation could greatly speed the build process of Gentoo packages (and not only Gentoo, of course). If you tend to use Gentoo on a laptop or a relatively old CPU you may want to build packages distributively across multiple hosts.
Different (Linux) distributions use different configurations and environment scheme and sometimes it is difficult to sift the configuration, which could be applied to your setup. This is not a tutorial on how to enable parallel processing in Gentoo but it is just our client-site setup.

By default, there is a limit of 4 parallel processes, which is utterly insufficient, because nowadays most servers have more than 8 cores/logical compute units (not to mention that probably most would have 16 and above cores compute units).

The environment variable DISTCC_HOSTS controls, which hosts will receive files for the compilation of what they support and what is the limit of parallel processes.

In Gentoo we set this variable in the /etc/portage/make.conf. Here what you may include in make.conf to have 16 parallel remote processes and up to maximum 4 local (if the remote fails):

MAKEOPTS="-j16 -l4"
FEATURES="distcc"
DISTCC_HOSTS="192.168.0.101/16"

We use the environment DISTCC_HOSTS (here in Gentoo put in the make.conf, but in another Linux distribution an environment variable with this name should be set) because it is easy to set up and control globally for the Gentoo emerge system.
According to the documents:

In order, distcc looks in the $DISTCC_HOSTS environment variable, the user’s $DISTCC_DIR/hosts file, and the system-wide host file.

So when using emerge to build the packages, the emerge will rely on $DISTCC_HOSTS in make.conf (/etc/portage/make.conf or /etc/make.conf if you still use the old path), “/var/tmp/portage/.distcc/” (the build process uses “portage” user and group, not root!) and “/etc/distcc/hosts”. The first option used in the order above will be set the hosts and the limitation for the distributed processing. So if you use $DISTCC_HOSTS in make.conf (or environment) you wouldn’t need to set the “hosts” file.
Separate the different hosts with white space if you have more than one and always use the notation “/LIMIT” for each host. The default value is only 4 parallel processes (i.e it is implicitly added /4 to each hosts in the configuration!)

Q_WEBENGINECORE_EXPORT QWebEngineFindTextResult has initializer but incomplete type

In addition to one of the cstdlib fix here – Gentoo building qtgui error – g++-v8/cstdlib:75:15: fatal error: stdlib.h: No such file or directory we were unable to to build “dev-qt/qtwebengine-5.14.1“.

It appeared the problem was a wrong order of header includes just like the cstdlib and if you have used the fix with QMAKE_CFLAGS_ISYSTEM in /usr/lib64/qt5/mkspecs/common/gcc-base.conf you would encounter this error. Revert back the original value in /usr/lib64/qt5/mkspecs/common/gcc-base.conf (and probably it is a good idea to rebuild the entire system with “emerge -e”):

QMAKE_CFLAGS_ISYSTEM = -isystem

and continue the build from the point you’ve stopped with something like:

ebuild /usr/portage/dev-qt/qtwebengine/qtwebengine-5.14.1.ebuild compile
ebuild /usr/portage/dev-qt/qtwebengine/qtwebengine-5.14.1.ebuild install

env python3.5: no such file or directory

The dependency conflicts may require a lot of time to resolve. On the contrary, uninstalling old software is easy, but it might lead to multiple broken programs and strange errors. Here is one of them, after removing the old python 3.4 and 3.5 (or whatever version it prints in your case) under Gentoo despite the rebuilding all dependencies as required by the emerge command for the new python 3.6 an error occurred trying to emerge the “app-misc/geoclue-2.5.3-r2

Despite the lines starting with “/usr/lib/python-exec/python3.6/meson”, there is an error for missing “python 3.5“.

Here is another example, just trying to execute the distcc-config and it immediately throws the error for missing “python 3.5“.

root@srv ~ # distcc-config 
/usr/bin/env: ‘python3.5’: No such file or directory

The python script distcc-config starts with:

options=[

        '--set-hosts',

Apparently, multiple programs use this technic to explicitly put a specific version of python in the header of the python script to be used. Thus grantees the version in the header will be used even you change the system or user-preferred Python interpreter.

But uninstalling this python version all these programs will stop working till you rebuild them with emerge.

display packages from the Gentoo emerge resume list

A quick tip and an easy hack to see the emerge resume list, which will be used by the “emerge –resume” command. There are two resume lists – resume and resume_backup in the binary file /var/cache/edb/mtimedb.
The first two commands are python 3+.
The resume and resume_backup lists

python -c 'import portage; print(portage.mtimedb.get("resume", {}).get("mergelist"))'
python -c 'import portage; print(portage.mtimedb.get("resume_backup", {}).get("mergelist"))'

If you need the command for the python 2 you should use the following:

python -c 'import portage; print portage.mtimedb.get("resume", {}).get("mergelist")'
python -c 'import portage; print portage.mtimedb.get("resume_backup", {}).get("mergelist")'

Real world example

Resume list for

desktop ~ # emerge -v --nodeps $(qlist -IC|grep dev-qt)

These are the packages that would be merged, in order:
