Q47931: Linker Error L1063 and Linking Over 1000 Object Modules
Article: Q47931 Product(s): See article Version(s): 5.01.21 5.03 Operating System(s): OS/2 Keyword(s): ENDUSER | S_C S_CodeView | mspl13_basic Last Modified: 16-AUG-1989 Question: When attempting to link a large OS/2 application consisting of over 1500 object modules with C 5.10's Link 5.01.21 or FORTRAN 5.00's Link 5.03 by using the options /co /map:2078 /noe /se:2078 /packcode, I get the link error "L1063 out of memory for CodeView information." Only one of the .C source files was compiled with /Zi. All were compiled with /AL. Linking without /co (CodeView information) successfully produces a 700K executable file (.EXE), but I need to do some debugging with CVP. What is the L1063 error, and how can I work around it? Response: Information on L1063 is not in the C 5.10 text files or documentation, but it is in Pascal 4.00's README.DOC and in FORTRAN 4.10's CVREADME.DOC as noted in another article in this knowledge base. The following reiterates the error message and its description: L1063 out of memory for CodeView information The linker was given too many object files with debug information, and the linker ran out of space to store it. Reduce the number of object files that have debug information. In this case, it is not the number of modules with CodeView information that is causing the problems exactly; it is the great number of modules and trying to link in any CodeView information. The following are ways to workaround this linker limitation: 1. The most effective method is to demodularize your application. That is, put more functions into fewer .C source files. 2. Reduce the linker option /se: value to as low as possible for the number of logical segments in the application. 3. Link the object files from the current working directory. If you must use different directories for your .OBJs, make the pathnames as short as possible.
