makedepend
Environment variables
makedepend uses the following environment variables. For a full description of
these variables, see the Environment Variables topic of c89 — Compiler invocation
using host environment variables.
{_ACCEPTABLE_RC}
Used by c89/cc/c++ to determine the maximum allowed return
code (result) of any step (compile, assemble, IPA link, prelink, or
link-edit). If the result is between zero and this value (inclusive),
then it is treated internally by makedepend exactly as if it were a
zero result. The default value is 4.
{_CLASSLIB_PREFIX}
Provides a prefix for the data sets used during the compilation and
execution phases. For makedepend, the focus is the
{_CLASSLIB_PREFIX}.SCLBH.+ data set that contains the z/OS
C/C++ Class Library include files.
{_CSUFFIX} Used by c89/cc/c++ to recognize a C source file. The default value
is c.
{_CSUFFIX_HOST}
Used by c89/cc/c++ to recognize a C source file. The default value
is C.
{_CXXSUFFIX}
Used by c++ to recognize a C++ source file. The default is C. This
variable is only supported by the c++ command.
{_CXXSUFFIX_HOST}
Used by c++ to recognize a C++ source data set. The default is
CXX. This variable is only supported by the c++ command.
{_CSYSLIB} Used for system library data set concatenation, which resolves
#include directives during compilation.
{_INCDIRS} Provides directories used by c89/cc/c++ as a default place to
search for include files during compilation (after searching
{_INCDIRS} and before searching {_CSYSLIB}).
{_INCLIBS} The directories used by c89/cc/c++ as a default place to search for
include files during compilation (after searching {_INCDIRS} and
before searching {_INCLIBS} and {_CSYSLIB}).
{_OSUFFIX} Provides a suffix by which c89/cc/c++ recognizes an object file.
{_CVERSION} The version of the C/C++ compiler to be invoked by c89/cc/c++.
The setting of this variable allows c89/cc/c++ to control which
C/C++ compiler program is invoked. It also sets default values for
other environment variables. The format of this variable is the same
as the result of the Language Environment C/C++ Run-Time Library
function _librel(). The default value is the result of the C/C++
Run-Time library _librel() function. Actual variable names are:
_C89_CVERSION, _CC_CVERSION, _CXX_CVERSION
{NO_CMDOPTS}
Controls how the compiler processes the default options set by c89.
Setting this variable to 1 reverts the compiler to the behavior that
was available prior to z/OS V1R5, when the compiler was unable to
distinguish between the c89 defaults and the user-specified options.
Setting this variable to 0 (zero) results in the default behavior where
