Entware [SOLUTION] Cross-Compile Torsocks Entware Package via Debian Live DVD

garycnew · Jun 24, 2021

NOTE: After finally being convinced by the Entware & OpenWRT Developers that neither Build Environment was meant to be Compiled Natively on a Router (Neutered C Libraries), I decided to pursue this Cross-Compile Torsocks Entware Package via Debian Live DVD solution; which, is presumably a bit slower, but ultimately successful. It wasn't too terrible after finding the right cross-compiling platform and combining a few different build references.

Requirements/Assumptions:

Cross-Compiling Host Machine:
1. Plenty of Physical Memory (RAM)
2. Debian Live (Testing) DVD
3. Flash Drive >= 32GB (Preferably USB 3.0/3.1)

Torsocks Installation Machine:
1. An Asuswrt-Merlin Compatible Router (i.e., Asus RT-AC66U)
2. Asuswrt-Merlin Compatible Firmware (i.e., 384.19)
3. Formated JFFS Partition and Enabled JFFS Custom Scripts and Configs
4. Entware installed on USB 3.0 Interface Device via Asuswrt-Merlin Terminal Menu (AMTM) with Swap File created

NOTE: Not sure if it matters... At the time of this writing, Debian Bullseye (Testing) Live DVD contained the same package versions as the current Entware repository, opposed to the Debian Buster (Stable) Live DVD, so we opted to use the Debian Bullseye (Testing) Live DVD.

### Download & Burn Debian Live (Testing) DVD ###

Code:

$ curl -L -O -C - http://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/weekly-live-builds/amd64/iso-hybrid/debian-live-testing-amd64-gnome+nonfree.iso

### Boot Debian Live (Testing) DVD on the Cross-Compiling Host Machine ###
Our Cross-Compiling Host Machine required the [F12] key to be pressed during boot to enter into the Boot Menu and select the Debian Live (Testing) DVD. Make sure you setup and have Internet access on the Cross-Compiling Host Machine.

### Open Terminal ###

### Mount Flash Drive (Repeat after each DVD Boot) ###

Code:

$ sudo -p /media/user/SanDiskSDCZ
$ sudo mount /dev/sdb1 /media/user/SanDiskSDCZ
$ cd /media/user/SanDiskSDCZ/

### Download & Install Build System (Repeat after each DVD Boot) ###

Code:

$ sudo apt-get update
$ sudo apt-get install git-core build-essential libssl-dev libncurses5-dev unzip gawk zlib1g-dev
$ sudo apt-get install python2 wget

### Clone, Setup, & Make Entware Build Env ###

Code:

$ git clone https://github.com/Entware/Entware.git
$ cd Entware

# Update OpenWRT Feeds
$ ./scripts/feeds update -a

# Symlink Packages (Repeat after each DVD Boot)
$ make package/symlinks

# Copy the config specific to your Architecture and Kernel versions
$ cp configs/armv7-2.6.config .config

$ make tools/install && make toolchain/install && make target/compile
or
#$ make -j1 V=sc tools/install
#$ make -j1 V=sc toolchain/install
#$ make -j1 V=sc target/compile

### Download, Prepare, & Compile Test Package from OpenWRT Feed ###

Code:

#$ ./scripts/feeds install screen
or
$ make -j1 V=sc package/screen/download
$ make -j1 V=sc package/screen/check
$ find package/ -iname "*screen*"
package/feeds/packages/screen

$ make -j1 V=sc package/screen/prepare
$ make -j1 V=sc package/screen/compile

#$ make package/index

$ find bin/ -iname "*screen*"
bin/targets/armv7-2.6/generic-glibc/packages/screen_4.8.0-2_armv7-2.6.ipk

### Download & Prepare OpenWRT Feed Package modified for Entware (When Available) ###

Code:

#$ ./scripts/feeds install torsocks
or
$ make -j1 V=sc package/feeds/packages/torsocks/download
$ make -j1 V=sc package/feeds/packages/torsocks/check
$ find package/ -iname "*torsocks*"
package/feeds/packages/torsocks

will you stay around to migrate/update this as Merlin drops support for your testing platform please? the AX series is quite a powerhouse compared to the early AC series stuff

@heysoundude It should be a trivial matter of just using the desired pre-rolled architecture-kernel.config file.

Code:

# Copy the config specific to your Architecture and Kernel versions
$ cp configs/armv7-2.6.config .config

"Sounds" like a good opportunity for someone else to play in the sandbox. Watch out for the worms, though.

I hate to think that my AiMesh Nodes will have to be migrated, someday. If I do it right, it shouldn't be too painful, though. This is a step in that direction.

Currently, I don't have any wireless devices that make use of 802.11ax.

they'll work until they don't...I'm really happy with my ac86 - a big step up from the n66 it replaced, but it's also starting to show signs of middle age, much like its owner ;-p
