I have a small C++ program which I am compiling on a ubuntu machine. The program runs fine on the same machine, but when I copy and try to run on a different linux system it printed
./prog1 : No such file or directory.
Further probing I realized the VDSO (linux-vdso.so.1) support is not enabled on the kernel running in target linux machine.
Below is the output of ldd of the program from my linux machine.
linux-vdso.so.1 => (0x00007fffda425000)
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f6ce9114000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f6ce8efe000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f6ce8b38000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f6ce8832000)
/lib64/ld-linux-x86-64.so.2 (0x00007f6ce9432000)
Now I want to know how do I compile my code in my ubuntu pc to run this on the target ?

the binary is marked for execution so tat is not the problem. and VDSO is not definetly the issue because I found the target kernel supports that.
Now I found a difference between the target kernel and the kernel installed on my ubuntu PC.
From target .... xmllint: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=9dc806b0866749772b0d2458ae74e7cea6e9a4aa, stripped
From Ubuntu ----- prog1: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=4ab095886f476674a7bf30c11d5479f7daa91001, not stripped
So should I have compile my code with the higher kernel version i.e 2.6.32 ?
