NATURAL v6 (6.3) I think

NATURAL calling a C program under Solaris is working. NATURAL calling same C program under Linux gets a NAT0920.

Tried with the ncuxinit.c and jumptab.c from Solaris. Also changed jumptab.c to better match the template on Linux.

ncuxinit, jumptab, C program are compiled / linked into natuex.so.

NATUSER is exported with the correct path to natuex.so.

Error message does not include any return code.

Check CDYNAM profile parameter and if this is static program also check CSTATIC parameter.

Thanks Evgen,

Yes CDYNAM is set ON. And we are calling the program dynamically, not statically.

Any other thoughts or ideas are very much appreciated!
