Install resilio on arm router

[colthreepv]

I am trying to install Resilio sync on an Asus RT-AC56U, It should have the hardware to run it correctly.

Executing it will just say:

root@tomato:/opt/usr/bin# ./rslsync
-sh: ./rslsync: not found

 

It might be related to the fact the small distribution on top of it (Tomato Shibby) does not have bash available in /bin/, but it's on /opt/bin/ 
I think making the app executable on those ARM routers would be a killer feature.

complete list of supported routers, all the listed as K26ARM would be automatically compatible

try armhf build https://download-cdn.getsync.com/2.4.4/linux-armhf/resilio-sync_armhf.tar.gz

Same outcome, to debug this more It would really helpful to understand what the executable doesn't find

[Helen]

first of all:
ldd ./rslsync 

then try to remove and then add x attribute to the file.

-sh: ./rslsync: not found
root@tomato:/opt/usr/bin# chmod -x rslsync
root@tomato:/opt/usr/bin# chmod +x rslsync
root@tomato:/opt/usr/bin# ./rslsync
-sh: ./rslsync: not found
root@tomato:/opt/usr/bin#

EDIT: I see, I used the command on a scaleway ARM server, and it correctly works and prints out linked libraries, I will try to get around them

EDIT2: Is there any statically-compiled version of Sync? - I don't think it will ever be, reading this thread

EDIT3: What I found out:

Linked libraries:

root@scw-a6ca74:~# ldd rslsync
        librt.so.1 => /lib/arm-linux-gnueabihf/librt.so.1 (0xb6f8a000)
        libcrypt.so.1 => /lib/arm-linux-gnueabihf/libcrypt.so.1 (0xb6f4b000)
        libdl.so.2 => /lib/arm-linux-gnueabihf/libdl.so.2 (0xb6f38000)
        libm.so.6 => /lib/arm-linux-gnueabihf/libm.so.6 (0xb6ec0000)
        libpthread.so.0 => /lib/arm-linux-gnueabihf/libpthread.so.0 (0xb6e9c000)
        libc.so.6 => /lib/arm-linux-gnueabihf/libc.so.6 (0xb6daf000)
        /lib/ld-linux-armhf.so.3 (0x7f567000)

 

Entware-ng ships out with the majority of files covered in /opt/lib/

It was missing ld-linux-armhf.so.3 so I ripped it from an ubuntu 12.04 ARM version.

The major issue is now that routers have read-only partitions for /bin /lib /usr and so on... so the standard way to specify linked libraries paths is via  LD_LIBRARY_PATH

but trying:

root@tomato:/opt/usr/bin# LD_LIBRARY_PATH=/opt/lib ./rslsync
-sh: ./rslsync: not found

I don't think the binary follows the standard environment variable.

 

At this point there no much I can do without a different executable, I think.

Any news on this? 

[Helen]

The team has not plans to get a statically compiled Sync binary,so you'll need to manually create symlink to lib

[colthreepv]

A dynamic compiled Sync binary might be fine, if it follows the LD_LIBRARY_PATH environment variable - there is any information regarding this from the dev team?

[Helen]

the problem is not in the variable. The problem is in missing library, and I cannot guarantee that ubuntu's libs will work on arm Asus RT-AC56U router. 
So you need yo find the native ld-........so and link to that either through symlink (/lib/ld-linux-armhf.so.3) or, if you prefer it that much, varibale

@colthreepv check this http://nixos.org/patchelf.html

Thanks, this tool has been of great help, nonetheless I think the problem is actually with my firmware (tomato-shibby)
I am not really a firmware compiler, for what I could understand the libc6 and kernel must be compatible, and the ones on that firmware does not play nice with Resilio

I have succesfully tried other libc6 versions from debian (thanks to your tool), but they just don't run on the device

It might need someone with more knowledge than me, or a different firmware; I suppose something more flexibe as openWRT will have no problems running resilio, just tomato is something more handy for day-to-day use

Anyone get this working on AsusWrt?
