Hi,

Can someone tell me what will be the difference between the binary that is built on Redhat8 and Suse9 even when compiler version is same i.e GCC 3.2.3 is used on both?I mean if I build an application on Suse9 using GCC 3.2that was supposed to be built on Redhat8 using GCC 3.2 what all problems do I face with respect to compilation linking and loading?

Thanks in advance

Do you mean you want to copy an executable image file from Suse to Redhat and then run it on Redhat (or wherever)?

You should recompile. I do not know specifcally what will go wrong if you do not recompile.

No.Somebody has asked me to build a binary on Redhat8 using GCC V3.2 compiler.Since I dont have Redhat8 m/c with me,I am thinking of using same GCC V3.2 on Suse9 to build the binary.Does it cause any Linking and loading problems to the customer in using the binary delivered by me?

That IS what I meant. Yes it has a high probability of causing problems - each of those distros has added features and directories, etc. If the code is pure base C with no libraries other than libc it may be okay.

It will also have a lot better chance to work if you link it statically - which results in a huge executable.

The only way you can partially test that the dynamic linking is compatible is to put the foreign binary on host and

Code:

ldd foreign_binary

If ldd reports problems you are out of the game from the get-go.

The likely error after that is 'undefined symbol' at runtime.

Thanks a lot..your replay has solved the issue i was facing..
