Installing Toolchain

Question

I'm trying to install a toolchain in Ubuntu 18.04 to compile a custom firmware for my router. The README states to run ./configure but when I do so it comes back with: configure: error: cannot find install-sh, install.sh, or shtool in config "."/config.

This is for an Asus DSL-AC88U for which I downloaded the source code from http://www.asus.com/uk/Networking/DSL-AC88U/HelpDesk_Download/ which contains the source code for router and toolchain.

After autoreconf -i the ./configure now runs, but I run make and get:

make[1]: Entering directory '/home/katana/Downloads/GPL_DSL_AC88U_v11006_build591/crosstools-arm-gcc-4.6-linux-3.4-uclibc-0.9.32-binutils-2.21-NPTL.Rel1.2' 
CC loaders/dlopen.lo ./libtool: ./libtool: Is a directory Makefile:694: recipe for target 'loaders/dlopen.lo' failed make[1]: ***

You need install build tools at first:

sudo apt-get install build-essential git ncurses-dev subversion zlib1g-dev m4 automake autoconf

And do not extract their toolchain to /opt at all. It will not work. It requires newer version of m4 and some other stuff. The firmware is based on OpenWRT, so it can compile toolchain on its own.

Then extract the DSL-AC88U_FW_V1_10_06_Build591_GPL_official.tar.bz2 archive and go to firmware directory

cd ~/Downloads/GPL_DSL_AC88U_v11006_build591/DSL-AC88U_FW_V1_10_06_Build591_GPL_official

# download package with broken link
wget http://lmde-mirror.gwendallebihan.net/latest/pool/main/m/mklibs/mklibs_0.1.34.tar.gz -O dl/mklibs_0.1.34.tar.gz

and compile both the firmware and the toolchain with

make V=s

Notes:

1. the compilation on my 18.04.2 LTS machine failed, I did not get any factory/sysupgrade images.

2. extracting the toolchain to /opt does not help:

   cd /
   sudo tar -xf ~/Downloads/GPL_DSL_AC88U_v11006_build591/DSL-AC88U_FW_V1_10_06_Build591_GPL_official/crosstools-arm-gcc-4.6-linux-3.4-uclibc-0.9.32-binutils-2.21-NPTL.Rel1.2.tar.bz2
   

   and ends with

   autom4te: need GNU m4 1.4 or later: /opt/toolchains/crosstools-arm-gcc-4.6-linux-3.4-uclibc-0.9.32-binutils-2.21-NPTL/usr/bin/m4
