Q50711: "." on the LIBPATH Eases DLL Debugging, But Not for CVP 2.20
Article: Q50711 Product(s): See article Version(s): 2.20 2.30 Operating System(s): OS/2 Keyword(s): ENDUSER | | mspl13_basic Last Modified: 10-NOV-1989 When debugging OS/2 DLLs with protected mode CodeView (CVP), you must specify each DLL on the command line with an /L switch, and the DLL must be in the current directory as well as in a directory on the LIBPATH as set in CONFIG.SYS. For ease of debugging, if you put a period ("."), which means the current directory, as one of the directories on your LIBPATH, then a DLL in the current directory will also be on the LIBPATH and you won't need to have two copies of a DLL present on disk for debugging. This method only works for versions of CVP beginning with 2.30. CVP Version 2.20 will not recognize DLLs in a "." LIBPATH directory. If a copy of the DLL called by the program being debugged is not in the current working directory, you will not be able to trace into the DLL. If a copy of the DLL is not in a LIBPATH directory, CodeView will not be able to find the DLL. In this case, instead of coming up in the usual "debugging mode," CodeView immediately exits and returns to the command prompt after several seconds. Many DLL debugging problems arise from the fact that the copy of a DLL that is on the LIBPATH may be inadvertently out of date compared to the version in the current directory that is being used for debugging. By putting a period on the LIBPATH, the current directory becomes a LIBPATH directory and only one copy of the DLL needs to exist, thus eliminating any DLL update inconsistencies.
