Hi,
I am building firmware for RT-AC86U from source code asuswrt-merlin.382 in my linux viertual machine Ubuntu 16.04.1 but there are few errors.

I followed all your mentioned prerequisites steps but it does not work. Please help me in this case.

 

[RMerlin]

Broadcom's HND makefiles require bash. You have to symlink /bin/sh to point to /bin/bash.

I have done the same you said now but it gives the same error.

 

[RMerlin]

Double check your shell configuration, your error is related to your Makefile not using bash but some other unsupported shell instead.

 

[sufianabrar]

I followed all steps which are mentioned in asus.merlin.382 to build firmware of RT-AC86U in my virtual machine ubuntu 16.04 64-bit but nothing works. Do you have any more suggestions?

 

[RMerlin]

I don't, sorry. I use 16.04 myself, and the only thing that I had to change for the specific error message you posted was to ensure that /bin/sh pointed to bash, and that the default shell was bash.

lrwxrwxrwx 1 root root 9 Aug 27 02:16 /bin/sh -> /bin/bash

 

[sufianabrar]

I reinstalled again ubuntu 16.04 and all the methods mentioned in asus.merlin.382, new toolchain .(https://github.com/RMerl/am-toolchains) and symlinked

ln -sf /bin/bash /bin/sh

And now I receive two different errors during finalizing in building the firmware.

[RMerlin]

The explanation is pretty plain to me in that error output:

ERROR: Attempting to build as root.

Do not compile as root...

 

[sufianabrar]

I have entered this command: chmod -R 777 asuswrt-merlin.382 and it resolved my issue.
Now I have generated ac86u custom firmware.
Thanks for your help.
