Incompatibility issue between GNU ld (GNU Binutils for Ubuntu) 2.24 and GNU ld (GNU Binutils for Ubuntu) 2.20.1-system.20100303

[Laszlo Baji]

Hi,

 

I would like to get help from you, because I stumbled upon a  backward compatibility issue at linking my code.

The problem is that not all the generated shared objects  are linked to the executable despite the fact that the –verbose option says success.

The two distributions are :  "Ubuntu 14.04.1 LTS" and  "Ubuntu 10.04 LTS"

 

The expected result for LDD is:

               linux-vdso.so.1 =>  (0x00007fff9c1ff000)

               MyExample.so => /home/elszbaj/workspace/hellooo/bin/MyExample.so (0x00007f89d6186000)

               PCOType.so => /home/elszbaj/workspace/hellooo/bin/PCOType.so (0x00007f89d5f81000)

               libttcn3-parallel-dynamic.so => /home/elszbaj/devel/titan/Install/lib/libttcn3-parallel-dynamic.so (0x00007f89d5835000)

               libcrypto.so.0.9.8 => /lib/libcrypto.so.0.9.8 (0x00007f89d5497000)

               libxml2.so.2 => /usr/lib/libxml2.so.2 (0x00007f89d5145000)

               libpthread.so.0 => /lib/libpthread.so.0 (0x00007f89d4f28000)

               librt.so.1 => /lib/librt.so.1 (0x00007f89d4d20000)

               libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007f89d4a0b000)

               libm.so.6 => /lib/libm.so.6 (0x00007f89d4788000)

               libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007f89d4571000)

               libc.so.6 => /lib/libc.so.6 (0x00007f89d41ee000)

               libdl.so.2 => /lib/libdl.so.2 (0x00007f89d3fea000)

               libz.so.1 => /lib/libz.so.1 (0x00007f89d3dd3000)

               /lib64/ld-linux-x86-64.so.2 (0x00007f89d6391000)

 

And this is provided by "Ubuntu 10.04 LTS"

 

----------

The faulty 14.04  LDD output looks like this:

               linux-vdso.so.1 =>  (0x00007fffa61fe000)

               libttcn3-parallel-dynamic.so => /home/elszbaj/devel/titan/Install/lib/libttcn3-parallel-dynamic.so (0x00007fa214fa2000)

               libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fa214bc3000)

               libcrypto.so.1.0.0 => /lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007fa2147e9000)

               libxml2.so.2 => /usr/lib/x86_64-linux-gnu/libxml2.so.2 (0x00007fa214483000)

               libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fa214264000)

               libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007fa213f60000)

               libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fa213c5a000)

               libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007fa213a43000)

               /lib64/ld-linux-x86-64.so.2 (0x00007fa2156d0000)

               libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fa21383f000)

               libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fa213626000)

               liblzma.so.5 => /lib/x86_64-linux-gnu/liblzma.so.5 (0x00007fa213403000)

 

The lines in red are missing from the faulty output.

 

I have attached the log files generated by –verbose (generated by Notepad++).

I have tried to use the linker script of the 10.04 as an external one to 14.04, but it has not helped either.

 

I am looking forward to getting your answer

 

Best regards
