Gentoo building qtgui error – g++-v8/cstdlib:75:15: fatal error: stdlib.h: No such file or directory

Most cases this error happens after you updated the GNU GCC (this update triggers the error, but it might be not the problem)! This was the case with us we updated the GNU GCC and then wanted to update QT libraries and several packages were built OK, but then this error occurred when compiling dev-qt/qtgui.

portage is blocked by “the current version of portage supports EAPI ‘6’. You must upgrade”

We’ve synced the portage tree before upgrading our old portage package (big mistake! always upgrade the portage package before sync) and then do the sync. After the sync the portage upgrade was impossible, because a dependency package supported only a new portage API (probably a new package) in our case EAPI 7 and the offensive package was “app-eselect/eselect-pinentry“.
So there are two options:

  1. Find the last version of the portage,which does not depend on the package – app-eselect/eselect-pinentry
  2. Find if some of the USE flags disable the inclusion of this dependency – app-eselect/eselect-pinentry

We chose the second option and found that if we compiled the portage package with

-rsync-verify

the portage did not pull the dependency “app-eselect/eselect-pinentry” and then after a successful upgrade we had the portage supported EAPI 7 and reinstalled it with activated “-rsync-verify”.

Access Violation error when compiling packets in Gentoo – symlink

Here is another example of Access violation error when building packages in Gentoo. This time the build process could not make a symbolic link in “/usr/bin” and the build process of the package failed with:

 * ACCESS DENIED:  symlink:      /usr/bin/stransmit
CMake Error: failed to create symbolic link '/usr/bin/stransmit': permission denied

A detail explanation is available in our first article on the subject here – Access Violation error, when compiling packets in Gentoo.
All packages are built in a sandbox and there is a sandbox configuration in

/etc/sandbox.d/00default

, which instruct the build process where could write. If you get such error in 99.99% there is a bug in the package and if you do not want to wait for fixing it (report it!) you can manually edit the SANDBOX_WRITE variable and add the path, which causes the build failure. Build the package and remove the added path!!! Or you risk to make your system less secure!

>>> Failed to emerge net-libs/srt-1.3.1, Log file:

>>>  '/var/tmp/portage/net-libs/srt-1.3.1/temp/build.log'

In the installation phase occurred the package failure leaving half installed package. So we edited the “/etc/sandbox.d/00default” and added “:/usr/bin” at the end of SANDBOX_WRITE:

SANDBOX_WRITE="/usr/tmp/conftest:/usr/lib/conftest:/usr/lib32/conftest:/usr/lib64/conftest:/usr/tmp/cf:/usr/lib/cf:/usr/lib32/cf:/usr/lib64/cf:/usr/bin"

Then rebuild the package with emerge and remove the added path “:/usr/bin”. This is a dirty workaround, but it will allow you to use srt (and as a dependency to another packages’ installation).

ffmpeg chroot jail from Gentoo linux (ffmpeg 4.1 with gcc 8.2)

Here we build a Gentoo ssh chroot jail. You may need this because

  • you want the bleeding edge versions of the video libraries like x264, x265, ffmpeg the latest version and so on.
  • latest version of GNU C library and the compiler GNU GCC (version 8.2) at the moment
  • use all the optimizations for compiling the ffmpeg and the libraries for you current processor. Use “-march=native”
  • you want just to be able to update your system and not to break your carefully compiled latest version ffmpeg
  • experiment with GCC compile flags
  • update and test in another directory by just copying the old chroot jail directory
  • no need of any additional software on the host (like virtualization lxc, docker, qemu, etc)
  • or you might want a 32bit version (why? really? but it is possible…)

Of course, you can use for the base any Linux system, but it is easy with Gentoo – the latest versions of almost all important libraries and a packet system, which builds everything for you after a little bit of first tuning…

So here is how to do it:

Compilation failure in configure with syntax error near unexpected token -Wall,WFLAGS and AX_CHECK_COMPILE_FLAG

If you are trying to build program and in the configure stage you got something like this:

./configure: line 6849: syntax error near unexpected token `-Wall,WFLAGS="$WFLAGS -Wall"'
./configure: line 6849: `AX_CHECK_COMPILE_FLAG(-Wall,WFLAGS="$WFLAGS -Wall")'

You are missing

autoconf-archive

Check your system for the package including this software (a collection of freely re-usable Autoconf macros): https://www.gnu.org/software/autoconf-archive/

In our case we were experiencing a missing dependency for “app-admin/metalog” in Gentoo Linux system. Probably there is a bug, because autoconf-archive is not in the dependency graph of “app-admin/metalog” (app-admin/metalog-20181125), but it should be included.
Such kind of error could occur in all Linux systems. Here is what to install in

  • CentOS 7
    yum install autoconf-archive
    
  • Ubuntu 16/17/18+
  • apt install autoconf-archive
    
  • Gentoo Linux
  • emerge -va autoconf-archive
    

Gentoo distcc compilation error – relocation R_X86_64_32 against .rodata.str1.1 can not be used when making a shared object

In our Gentoo systems we use distcc (distributed builds for C, C++ and Objective C) to build the packages fast! But after we upgraded to GNU GCC 8.2 some of the packages we tried to build failed with:

 0:02.86 /usr/lib64/distcc/bin/x86_64-pc-linux-gnu-gcc -std=gnu99 -o nsinstall_real -DXP_UNIX -O2  host_nsinstall.o host_pathsub.o

 0:02.88 collect2: error: ld returned 1 exit status
 0:02.88 distcc[528] ERROR: compile (null) on localhost failed

As you know the GNU GCC must be (same versions and) compiled with the same flags on the two systems you use it – the local machine and the distcc build server. So we were pretty sure the GNU GCC is the same version in our local machine and the build distcc server, because the USE flags were the same in /etc/portage/make.conf but executing

gcc -v

showed there is a slight difference.

The difference is in local has –enable-default-pie and distcc server has –disable-default-pie

Investigating farther we discovered that the USE make.conf flag is “pie” – https://packages.gentoo.org/useflags/pie and this flag is for “Build programs as Position Independent Executables (a security hardening technique)”. And the problem was the default value on the local machine it was enabled by default and for the remote it was disabled by default –

SO the real problem was the different profiles set on the two servers!

The remote distcc server no one checked and switched to the new portage profile 17 so the server still used the old portage profile 13, where the flag “pie” was excluded.
So change the profile to the same as the local machine and recompile GNU GCC package:

compile ~ # eselect profile set 12
compile ~ # emerge -va gcc

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

Calculating dependencies... done!

Would you like to merge these packages? [Yes/No] Yes

As you can see the new flag enabled by “(pie*)”.

So be sure when using distcc the Gentoo portage profiles should be the same on the local and the remote distcc systems or you can end up with fatal differences and compilation errors!

>>> Failed to emerge dev-libs/libmemcached-1.0.18-r3, Log file:

We have installed automake, the dependency is OK, there is no need of new version of automake (the libmemcached did not required to install a new version as a dependency), but still the build process failed!
automake has many different versions installed on the same system and the problem is that one of your currently installed version is too old, so you must upgrade all versions (from the all different branches installed).
First check what versions are installed (equery is part of app-portage/gentoolkit):

root@srv ~ # equery list automake
 * Searching for automake ...
[I--] [??] sys-devel/automake-1.11.3:1.11
[I--] [??] sys-devel/automake-1.12.6:1.12
[I--] [??] sys-devel/automake-1.13.4:1.13
[I--] [??] sys-devel/automake-1.14.1:1.14
[IP-] [  ] sys-devel/automake-1.15.1-r2:1.15
[IP-] [  ] sys-devel/automake-1.16.1-r1:1.16

We have version from branch 1.11, 1.12, 1.13 and 1.14 – one of these version is causing the problem!
Up until now no package required as a dependency 1.15 and 1.16, so we do not have it installed.

Here we upgrade them all to their latest versions in every branch version:

root@srv ~ # emerge -vu sys-devel/automake:1.11 sys-devel/automake:1.12 sys-devel/automake:1.13 sys-devel/automake:1.14

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

Total: 4 packages (4 upgrades), Size of downloads: 5133 KiB

As you can see we have updated version in every branch! And after updating them the building of libmemcached passed smoothly!
It’s not only in Gentoo, in most Linux distros (such as Ubuntu, CentOS, Manjaro, Mint and so on) have multiple automake version installed, so if you encounter this problem check your automake version installed for their latest versions and also if you miss some of them.

Manual install of base Gentoo Linux x86_64 with openrc (init) and uefi using minimal installation cd

Here we are going to show the minimum steps to install a base Gentoo Linux on your computer – server or desktop using “Minimal Installation CD”.
The installation ISO CD is generated on 11.09.2018, but you can use an older or newer one, this guide uses commands, which are available in really old ISOs (10 years ago) and probably will be available in the future, too! The idea is not to change this ISO a lot and to have only the basic tools for installation, which should be the same for a really log time! If you need more tools there two other options: Hybrid IS0, which is a LiveDVD – a system with GUI and Admin CD, which is extended version of the minimal installation CD (no GUI).

Our base Gentoo system will use:

  1. OpenRC, which is based on init to boot the server. This is the default in Gentoo, but you might have problems using Gnome
  2. GRUB 2 UEFI enabled and the server will be booted in UEFI mode. Recently most of the desktop machine and server support it and in many cases it is mandatory to use a new hardware.
  3. No GUI will be installed (KDE, Gnome, Xfce and so on), there are other tutorials for this, you can check here (coming soon)

Gentoo Minimal Installation CD (amd64 aka x86_64) – booting (in UEFI mode)

Here is the process of booting from a Gentoo Minimal Installation CD amd64 (x86_64) with UEFI mode enabled. This is not an installation guide!
You can download the CD from here: https://www.gentoo.org/downloads/ Here is the ISO file: http://distfiles.gentoo.org/releases/amd64/autobuilds/20180911T214502Z/install-amd64-minimal-20180911T214502Z.iso or you can check it in some mirror like leaseweb – http://mirror.leaseweb.com/gentoo/releases/amd64/autobuilds/current-install-amd64-minimal/install-amd64-minimal-20180911T214502Z.iso.

Our motherboard is Asus ROG Zenith Extreme motherboard using X399 chipset https://www.asus.com/th/Motherboards/ROG-ZENITH-EXTREME/ and you’ll see the BIOS options for it, but they do not differ much with the other motherboard boot options. Here also setup the network and start up an openssh server to manage our Gentoo Linux installation – (coming soon).

Gentoo update tips when updating packages with blocks and masked files

It’s not so rear to have

blocks or masked files

when using Gentoo emerge system, but it is not complex and in most cases it is easy to resolve

To summarize it up at the beginning and then we are going to show you other articles using these advises here where you’ll see what are the steps we took to resolve the conflicts and masked packages:

  • Use verbose,verbose-conflicts and backtrack with emerge
  • Remove only big GUI packages, which have really big dependency graph like office suites or development IDEs
  • Remove obsolete packages – you do not need them, they can just make problems when updating, because emerge will take into consideration their requirements and dependencies and your update could be impossible!
  • Do not update everything with one line, you could update only the base libraries like QT, which are very important for the Linux GUI in general
  • Include explicitly packages, which block our updates in the emerge line! You could specify packages with the versions.
  • use tools like “equery” (part of app-portage/gentoolkit) for checking dependencies and/or which packages depend on the queried package. You can use it with specific version for the package. “qlist” (part of app-portage/portage-utils) also is a handful tool.
  • Sometimes when updating a group or a package with big dependency graph it is much easier to drop the -“u” update argument and to rebuild some packages with the updates.
  • In rear cases you can use “–nodeps” when updating or installing a new package (we do not need and show this one here!)
  • Do NOT rebuild the entire system with “emerge -v world” every time when you rebuild glibc, gcc, it is not mandatory to do it to have a healthy system.
  • Add or remove USE flags if needed – emerge will show you information about it. Use package.use, package.mask, package.unmask and so on.
  • use qlist to update/re(build) to pull currently installed packages with some name or category (categories)
    emerge -v $(qlist -IC|grep <NAME>)
    

    and for update just add “u” to “-v”:

    emerge -vu $(qlist -IC|grep <NAME>)
