Trying to compile, in Ubuntu inside Windows 10 gives me this error, can you help me to solve?

Mkhash is ap rogram built by OpenWrt itself. The error must be elsewhere, please provide more log context.

Hi
How can I create log files of the "make menuconfig" command ?

jow · May 17, 2018, 1:13pm

Try "make preqreq V=sc" and see if you get more verbose output.

hnyman · May 17, 2018, 1:24pm

have you updated the package database of the Linux subsystem?
"sudo apt-get update"?

yesterday
git clone https://git.openwrt.org/openwrt/openwrt.git

today
sudo apt-get update
sudo apt-get upgrade

Just a quick thought, completely uconfirmed -- since Python 3 is standard on current Ubuntu installs, and Python 2 is not only deprecated, but not installed, does mkhash require Python 2?

hnyman · May 17, 2018, 3:47pm

Looks like you have not installed gcc.
That is needed for mkhash compilation later.

(jow was naturally right, mkhash is compiled during the prereq test process, but it needs a wroknig gcc, first https://github.com/openwrt/openwrt/blob/master/include/prereq-build.mk#L159 )

EDIT:
you will need to check that you have installed the required prequisite packages, as explained in wiki:
https://wiki.openwrt.org/doc/howto/buildroot.exigence#prerequisites

I use this list in my own Ubuntu 18.04 build host (in Virtualbox):

### Prerequisites for buildroot                                           
sudo apt-get install build-essential subversion libncurses5-dev zlib1g-dev
sudo apt-get install gawk gcc-multilib flex git-core gettext libssl-dev   
                                                                          
### Prerequisite on Ubuntu 17.10 as it has python3 by default             
sudo apt-get install python

Thanks, now make menuconfig work, but not make.

jow · May 17, 2018, 5:22pm

make image is no valid make target for the buildroot, it is only used in the image builder. Simply run make without arguments to build a full system.

gioreva · May 17, 2018, 6:04pm

Make work

However, how do I select my personal IO map ?

I have put my config file on:
target/linux/ramips/dts/GEVA.dts

But I do not find it in the menuconfig options

I had a note, which I used to do in the past.
make image PROFILE=GEVA

Hi there,
I have got the same problem here. It was because the gcc I had been using was broken. Fixed it by updating gcc.
