It says I does not have g++, it says I need to install a patch.

I think the toolchain is properly installed, and environment correctly set.

Code

Hello

The gcc packages I have currently installed are attached (gcc packages.PNG)

Code

[rvelazquez@Fedora23 build-dir]$ rpm -qa | grep gcc
libgcc-5.3.1-6.fc23.i686
libgcc-5.3.1-6.fc23.x86_64
gcc-5.3.1-6.fc23.x86_64

Do I need gcc 5.3 but i686 architecture ??

Thanks

fs-support_HK · Dec 12th 2016

You need to install the packages gcc-c++ and patch (patch is a program to apply diff files, so-called patches, to an existing source tree).

Usually there are also some other packages needed:

glibc (i686)
glibc-devel (i686)
zlib (i686)
bison
wget
perl-ExtUtils-MakeMaker
texinfo
git

Depending on what packages you compile in Buildroot, more host packages may be necessary for your PC.

Hello

I have installed the packages you mentioned, and others. It got better.

Now I have the error

I can read "Your Perl installation is not complete enough;"
I have the "Perlbal" package installed, see please attached screen shot.

Moreover, it says there is not available any Perl package

Have you tried installing 'perl' written in lowercase? This is relevant.
In my case (Fedora 21) there is a perl package and its called 'perl.x86_64'.

So asking to install Perl says no package available.

Code

[ph@localhost ~]$ sudo dnf install Perl
Using metadata from Thu Dec 8 09:09:26 2016 (6 days, 3:32:13 hours old)
Kein Paket Perl verfügbar.
Fehler: no package matched: Perl

But asking for perl will find the package. In my case it's allready installed.

Code

[ph@localhost ~]$ sudo dnf install perl
Using metadata from Thu Dec 8 09:09:26 2016 (6 days, 3:32:19 hours old)
Paket perl-4:5.18.4-310.fc21.x86_64 ist bereits installiert, wird übersprungen.
Abhängigkeiten sind aufgelöst.
Nichts zu tun.
Komplett!

Perl is divided into a whole lot of small packages. For example try

Code

sudo yum list all "perl*"

and you'll see a list of more than 100 packages. Here you'll find the necessary sub-package. (Maybe you'll have to replace "yum" with "dnf".)

By the way I would use yum-extender as a graphical frontend. There you can easily search for packages.

Sorry, silly me on "Perl".

I found a clue in https://developer.fedoraprojec…es/perl/perl-modules.html

Finally I compiled succesfuly your fsimx6_std_defconfig.

Thanks again.

fs-support_PH · Dec 15th 2016

Perfect.

Thanks for posting the clue to perl-modules.
