SYMPTOMS

When you build a debug version of an application with FORTRAN PowerStation for MS-DOS version 1.0 (PS 1.0) and include object modules (.OBJ) compiled with FORTRAN PowerStation for MS-DOS version 1.0a (PS 1.0a), the following errors may be generated:
Assertion failed: i != C7FIXUPSYMCNT, file symbols7.c, line 314
-or-
CVPACK : fatal error CK1010: symbol error in module;
contact Microsoft Product Support Services
-or-
***** Linker INTERNAL ERROR during EmitCodeView *****

Command line error D2027 : cannot execute 'C:\F32\BIN\link32.exe'

CAUSE

The versions of CVPack and Link32 included with PS 1.0 may not be able handle the debugging information appended to object modules by the PS 1.0a compiler. PS 1.0a inserts debug information into the object module when you use the compiler options /Zi and /Zd, as expected, but also inserts some debug information when you use the /Ox compiler option.

RESOLUTION

Call Microsoft support, (425) 635-7015, and ask for the free update to Microsoft FORTRAN PowerStation for MS-DOS version 1.0a.

While using PS 1.0 do not build in debug mode or do not include object modules from PS 1.0a that have debug information.

Re-compile the object modules from PS 1.0a without using options /Ox, /Zi, or /Zp.

MORE INFORMATION

Version information


             PS 1.0   PS 1.0a
   --------------------------
   Link32      2.8      1.0F
   CVPack      4.21     4.25
To determine the version of CVPack, type the following at the MS-DOS prompt:

CVPACK

The version number will be displayed.

To determine the version of Link32, type the following at the MS-DOS prompt:

link32 | more

Steps to Reproduce the Problem

Because the Microsoft IMSL for FORTRAN PowerStation libraries were built with PS 1.0a using the /Ox option, they include some debugging information and can be used to demonstrate the problem.

  1. Build one of the samples from the Microsoft IMSL Libraries. For example, move to the C:\MSIMSL32\FORTRAN\EXAMPLES\MATH\DOUBLE directory and type the following at the MS-DOS prompt:

    fl32 -Zi dlprs_ex.for -link mathd.lib

    The following error is displayed:
    ***** Linker INTERNAL ERROR during EmitCodeView *****

    Command line error D2027 : cannot execute 'C:\F32\BIN\link32.exe'
  2. Modify the makefile so the compiler switch /Zi or /Zd is used.

    The following errors are displayed:
    CVPACK : fatal error CK1010: symbol error in module dlprs_ex.obj; contact Microsoft Product Support Services
    LINK32 : warning LNK4527: CVPACK error
    Command line error D2027 : cannot execute 'C:\F32\BIN\link32.exe'
    NMAKE : fatal error U1077: 'FL32' : return code '0x2'
    Stop.
