Utilities

The z/OS® XL C/C++ compilers provide the following utilities:

The xlc utility to invoke the compiler using a customizable configuration file.
The c89 utility to invoke the compiler using host environment variables.
The CXXFILT utility to map z/OS XL C++ mangled names to their original function names.
The DSECT conversion utility to convert descriptive assembler DSECTs into z/OS XL C/C++ data structures.
The makedepend utility to derive all dependencies in the source code and write these into the makefile. The make command will determine which source files to recompile, whenever a dependency has changed. This frees the user from manually monitoring such changes in the source code.
The CDAHLASM utility, which produces debug information in DWARF (for Metal C applications) and ADATA formats. This utility uses the HLASM assembler to compile the source files produced by compiling Metal C code.

Language Environment® utilities include:

The object library utility (C370LIB; also known as EDCALIAS) to update partitioned data set (PDS and PDSE) libraries of object modules. The object library utility supports XPLINK, IPA, and LP64 compiled objects.
Note: In this document, references to partitioned data set (PDS) include both the PDS and partitioned data set extended (PDSE) physical formats, unless stated otherwise.
The prelinker which combines object modules that comprise a z/OS XL C/C++ application to produce a single object module. The prelinker supports only object and extended object format input files, and does not support GOFF.
Note: IBM® has stabilized the prelinker. Further enhancements will not be made to the prelinker utility. IBM recommends that you use the binder instead of the prelinker and linker.
