Compilation compatibility between Linux and Solaris

Garfalala · 08-06-2003, 10:31 AM

A collaborator sent me an executable binary of a C++ program compiled under Solaris SunOS 5.8 but it seems to be impossible to run it under my station which is under Red Hat 9.0.

Is there any solution to make it compatible ?

Thanks for all replies.

You'll need to recompile it on a Linux system or use a cross-compiler.

the reason for this is a combination between the binary executable format, and the CPU architecture used... here are the file types for the same binary executable on x86 Debian Linux and SPARC Sun Solaris 9:

Code:

bash-2.05$ uname -a
SunOS sr-egmp03-02 5.9 Generic_112233-05 sun4u sparc SUNW,Sun-Fire
bash-2.05$ file ypcat
ypcat:          ELF 32-bit MSB executable SPARC Version 1, dynamically linked, stripped
bash-2.05$

Code:

hobbs@turnip:/usr/bin$ uname -a
Linux turnip 2.4.18-bf2.4 #1 Son Apr 14 09:53:28 CEST 2002 i686 unknown
hobbs@turnip:/usr/bin$ file ypcat
ypcat: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), stripped
hobbs@turnip:/usr/bin$

you can see that Solaris uses:

"ELF 32-bit MSB executable SPARC Version 1, dynamically linked, stripped"

...and debian uses:

"ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, stripped"

different formats...

Thanks for the details, fishsponge. I suspected this was this kind of problem. I just thought there was a way to get through this. Never mind, I'll try to get the source, now !

cool... thanks to stickman too, as it was him/her who provided the actual answer
