The Question is:
Just installed version 6.5 of C on a Alpha Server ES47 and when trying to
compile a C program I am getting the following error message:
GENC - C compile for UOQCIS
char *round(char *t,char *s,int decs)
.......^
%CC-E-NOTCOMPAT, In this declaration, the type of "round" is not compatible with
the type of a previous declaration of "round" at line number 756 in file SYS$CO
MMON:[SYSLIB]DECC$RTLDEF.TLB;4.
at line number 407 in file BAN_HOME:[GENERAL.C]GUASTDF.H;8
Could you tell me what is going on. I am a systems person not a programmer.
This looks like something wrong in the program to me. Or is it a systems
problem. Whatever the case please let me know what I need to do to resolve
the problem. Here is the i
nstall log from the C install:

Thanks in advance.
The Answer is : The compiler has flagged a coding error within the application, and specifically a case where the specified declaration does not match a previous declaration of the same name. (Newer versions of C are better at detecting and reporting latent errors.) In this case, the programming error involves the errant use of a function call name (round) that is reserved as part of the C99 standard. Without details of the code and the colliding definition -- probably the declaration of round() within math.h -- the OpenVMS Wizard cannot provide a more specific response. If this is round(), you can rename all existing calls to round() to another name -- specifically all calls not intending to call the C99 version of round(), obviously. Other workarounds are certainly possible, but the OpenVMS Wizard would not generally recommend them. (This particular name collision is also why the OpenVMS Wizard recommends using symbol prefixes on all code, as described in the Programming Concepts and the Modular Programming manuals. The prefixes reduce the likelyhood of naming collisions.) You or your designee will need to resolve this C coding error. To enable more extensive diagnostic messages, use the C compiler qualifier /WARN=VERBOSE. For details on the C compiler and the C programming language, please review the C manual. For assistance in debugging or recoding applications, please contact HP professional services organization.
