Andy22 Posted November 11, 2015 Report Share Posted November 11, 2015 Hi, there seem to-be a ARM binary, but it seems its not ARMv7l compatible so i can't run it on the latest lineup of openWRT compatible ARM routers/NAS? Getting BTSync to compile on openWRT should be relatively simple, since they have a good toolset in place and are very close to a "real" linux distribution in terms of available packages and there use of a extroot overlay filesystem. So is there a package available that is compatible and can be used on those ARM V7l, A9 Routers running openWRT/DD-WRT? Quote Link to comment Share on other sites More sharing options...
RomanZ Posted November 12, 2015 Report Share Posted November 12, 2015 @Andy22Actually, it is compatible. Did you try to run Sync ARM binary on your router? What exactly it says when you try to run it? Also, could you please show the output of /proc/cpuinfo file? Quote Link to comment Share on other sites More sharing options...
Andy22 Posted November 12, 2015 Author Report Share Posted November 12, 2015 Yes i did download the arm binary and extracting and setting the execute flag simply results in:./btsync-sh: ./btsync: not foundThis seems to indicate that the binary is not recognized as compatible executeable, since the file exists in the directory and has the +X flags. I can also run other binarys from the same location just fine. model name : ARMv7 Processor rev 1 (v7l)processor : 1BogoMIPS : 2655.84Features : half thumb fastmult vfp edsp vfpv3 tls vfpd32CPU implementer : 0x41CPU architecture: 7CPU variant : 0x4CPU part : 0xc09CPU revision : 1Hardware : Marvell Armada 380/385 (Device Tree)Revision : 0000Serial : 0000000000000000 Quote Link to comment Share on other sites More sharing options...
RomanZ Posted November 13, 2015 Report Share Posted November 13, 2015 @Andy22That's a linking issue. To solve it, find the linker binary refers to (run "file btsync" or "readelf -d btsync" command). Then you'll need to create a symlink pointing to the linker that actually exists on your OS. Quote Link to comment Share on other sites More sharing options...

Only problem is DD-WRT 3.0 does not come with a "file" or "readelf" binary... PS: Guess now i need to find out where i can grab a arm compatible readelf binary that runs on the router. I realy do not want to invest the time and install the DD-WRT toolchain and compile my own binutils. What clib you compile against btw? Maybe you might consider linking statically against MUSL in the future to prevent such cases for embedded devices? Quote Link to comment Share on other sites More sharing options...
RomanZ Posted December 4, 2015 Report Share Posted December 4, 2015 @Andy22You can do it on any other computer. For Sync 2.2.7 path is "/lib/ld-linux.so.3" so you can create a symlink pointing to the linker you have (likely /lib/ld-linux-arm*.so.3) We are compiling with GNU C Library 2.13. For the linking statically against MUSL - it is very unlikely we are going to implement it in future, although thanks for proposal. Quote Link to comment Share on other sites More sharing options...

RomanZ Posted October 10, 2016 Report Share Posted October 10, 2016 @asins wndr4300 has MIPS CPU. MIPS is not supported and ARM binary won't run on MIPS CPU. Quote Link to comment Share on other sites More sharing options...
