BADSVINDX running an executable on x86

[tdirven]

Hello,

I have ported a few applications to x86 (C and Fortran).
When I try to run the executable I get this error message:

$ RUN VCOM_SEND_RECEIVE

%DCL-W-ACTIMAGE, error activating image RMISHR
-CLI-E-IMGNAME, image file DSA100:[SYS0.SYSCOMMON.][SYSLIB]RMISHR.EXE
-LOADER-E-BADSVINDX, symbol vector index is too large

Is this is known error?

GN2111_SPP1121> di DSA100:[SYS0.SYSCOMMON.][SYSLIB]RMISHR.EXE/prot

In short, the build/link-time environment (for all referenced images) doesn't match the run-time environment.

While the DEC$FORRTL and LIBOTS haven't changed, I'll guess that one of the images referenced by SPP$DLSUBSTR.EXE has changed. Written in C++, BASIC? The link that hb posted is with C++ related changes but the concept is the same. You linked against some image (the RMISHR in the error message might not be the actual cause) and used some routine in the symbol vector. Then on the target system, the same RTL is older with fewer entry points and the image activator reports that "index too large" error.
