Timesys Linux BusyBox - Why I can't start a application from a shell in common way?

[dragan]

Respected Colleagues,

after who knows which factory build I cannot start application from a shell with command "./Test".

BusyBox v1.20.2 (2014-10-17 23:46:34 CEST) built-in shell (ash)

Enter 'help' for a list of built-in commands.

# ls

TEST  dev  lib  media proc  sbin  usr

bin  etc  linuxrc  mnt  root sys  var

config  home  lost+found  opt  run  tmp

# cd TEST

# ls

Test

# ./Test

-/bin/sh: ./Test: not found

#

Can somebody tell why is that, and how to solve this?

Thanks in advance.

With best regards,

Dragan Kujovic

Hi Dragan,

did you build Test with DS-5 GCC or with Timesys GCC? DS-5 GCC compiled applications need availability of

/lib/ld-linux-armhf.so.3

As a workaround you may make a soft link pointing to /lib/ld-linux.so.3

Respected Edward,

build was made with DS-5 GCC. But interesting is that I got this problem few days ago, when I compiled proram with arm7-a CPU option and with hard float option, instead of arm4t CPU option and soft float option that I used before.

What do you think about that?

Also, can you explain how and where to make soft link pointing to /lib/ld-linux.so.3.

Thanks in advance.

With best regards,

Try to un-tar attachment to your Vybrid RFS /lib folder.

Respected Edward,

thanks for your effort.

Yes, with your patch executable file compiled with ARM DS-5 GCC Compiler can work under  default Timesys Linux distribution.

If I use ARM DS-5 CORRECT compiler and linker CPU option for Vybrid A5 core "-march=armv7-a" executable work under  default Timesys Linux distribution only with your patch.

If I use ARM DS-5 INCORRECT compiler and linker CPU option for Vybrid A5 core "-march=armv4t" executable work under  default Timesys Linux distribution.

I think that Timesys must include your patch in the Timesys Linux distribution (Vybrid RFS /lib folder), to allow correct Vybrid A5 CPU Type choice in GCC Compiler / Linker.

With best regards,
