Hi Min,

thank you very much for your answer.

The programs work fine on my Solaris x86_64 and Linux machines
as well. I only have a problem on Solaris Sparc.

No, it wil not work, because the programs are stored in a
different directory ($HOME/{SunOS, Linux}/{sparc, x86_64}/bin)
which is part of PATH (as well as ".").

Can I do anything to track the source of the error?


Kind regards

Siegmar
