The ECOB precompiler provides command-line tool options the same as those provided by proc. You can use the ECOB precompiler to compile the .pc source code files of Pro*C.
After you install ECOB, run the ecob -h command to view the help information of the command-line tool.
Usage:
ecob [INAME=]FILE [OPTION]...
Options:
[INAME=]filename Name of the input file
ONAME=filename Name of the output (code) file
INCLUDE=pathname Directory path for EXEC SQL INCLUDE or #include statements
SYS_INCLUDE=pathname Directory where system header files are found
DEFINE=name Define a name for use by the precompiler
PARSE={FULL|PARTIAL|NONE} Specifies the way that the precompiler parses the source file
VERBOSE={YES|NO} Generate verbose output
PARSE_SYS_INCLUDE={YES|NO}
PARSE_CPP_DIRECTIVE={YES|NO}
-v, --version Output version information, then exit
-?, -h, --help Show this help, then exit
If no output file is specified, the name is formed by adding .c to the
input file name, after stripping off .pc if present.
