PRB: ESQL: Errors When Linking COBOL Applications for MS-DOS

  - Microsoft Embedded SQL version 4.2 for COBOL

SYMPTOMS

You can use Micro Focus COBOL 3.0 or Microsoft COBOL 5.0 to compile and link MS-DOS applications with Microsoft Embedded SQL for COBOL Programmer's Toolkit (ESQL/COBOL). However, you may run into some linking errors using these versions of COBOL compilers.

When linking MS-DOS applications using ESQL/COBOL 4.2, you will normally use the following link command line as documented in the ESQL/COBOL 4.2 "Programmer's Reference":

   link yourprog.obj+sqlinim+MFC6INTF+C6DOSIF+C6DOSLB,,,
   lcobol+cobapi+llibcer+sqlakd+rldblib /NOE /NOD /NOF /NOP;

   rldblib.lib(..\..\src\dbmidio.c): error L2025: DOSSLEEP:
      symbol defined more than once
   rldblib.lib(..\..\src\dbmidio.c): warning L4004: possible
      fixup overflow at 24D in segment _DBMDIO
      target external 'DOSSLEEP'
   rldblib.lib(..\..\src\dbmidio.c): error L2002: fixup
      overflow at 24D in segment _DBMIDIO
      target external 'DOSSLEEP'

CAUSE

Due to changes in the new COBOL compiler libraries, the original link line for linking MS-DOS applications as documented does not work correctly.

WORKAROUND

To work around this problem, you can re-arrange the link line as follows:

   link yourprog.obj+sqlinim+MFC6INTF+C6DOSIF+C6DOSLB,,,
   lcobol+llibcer+rldblib+sqlakd+cobapi /NOE /NOD /NOF /NOP;
