Hi All -
I have SPARC working application code, which needs to be ported to solaris 10 x86. I added -D__386 to the compile flags. Compiled fine, but have problems in running. If I compile with -D_BIG_ENDIAN, seems like the application processes go further in execution than it was before. I am running out of options for trying different things. You help will be greatly appreciated
Regards

On which machine, the Sparc or x86?
We have no idea what steps you did on which machine.

Hello
The "-D_BIG_ENDIAN" shows you that the code is endian-dependent. This means that the program cannot be ported 1:1 because x86 is little endian while Sparc is big-endian.
I would first try to use "-D_LITTLE_ENDIAN" (or what flag ever I can find in the source codes) and to compile for x86.
Because of the "-D_BIG_ENDIAN" different source code is used for both machines. Maybe the little-endian source code is wrong:
#ifdef _BIG_ENDIAN
// correct source code for Sparc
#else
// INCORRECT source code for x86
#endif
