addDefines
Add preprocessor macro definitions to build information
Description
addDefines(
specifies the preprocessor macro definitions to add to the build information.buildinfo
,macrodefs
,groups
)
The function requires the buildinfo
and
macrodefs
arguments. You can use an optional
groups
argument to group your options.
The code generator stores the definitions in a build information object. The function adds definitions to the object based on the order in which you specify them.
Examples
Add Macro Definitions to OPTS Group
Add a macro definition -DPRODUCTION
to the build
information myBuildInfo
and place the definition in the group
OPTS
.
myBuildInfo = RTW.BuildInfo; addDefines(myBuildInfo,'-DPRODUCTION','OPTS');
Add a macro definition MYDEF
with value
MYVAL
.
addDefines(myBuildInfo,'-MYDEF=MYVAL','OPTS');
Add a macro definition MYDEF
with empty value.
addDefines(myBuildInfo,'-MYDEF=','OPTS');
Add a macro definition MYDEF
with undefined value.
addDefines(myBuildInfo,'-MYDEF','OPTS');
Add Macro Definitions to OPT_OPTS Group
Add the macro definitions -DPROTO
and
-DDEBUG
to the build information myBuildInfo
and
place the definitions in the group OPT_OPTS
.
myBuildInfo = RTW.BuildInfo; addDefines(myBuildInfo, ... '-DPROTO -DDEBUG','OPT_OPTS');
Add Macro Definitions to Build Information
For a non-makefile build environment, add the macro definitions
-DPROTO
, -DDEBUG
, and
-DPRODUCTION
to the build information myBuildInfo
.
Place the definitions -DPROTO
and -DDEBUG
in the
group Debug
and the definition -DPRODUCTION
in the
group Release
.
myBuildInfo = RTW.BuildInfo; addDefines(myBuildInfo, ... {'-DPROTO -DDEBUG' '-DPRODUCTION'}, ... {'Debug' 'Release'});
Input Arguments
buildinfo
— Name of build information object returned by RTW.BuildInfo
object
Object contains information for compiling and linking generated code.
macrodefs
— List of macro definitions to add to build information
character vector | array of character vectors | string
You can specify the macrodefs
argument as a character
vector, as an array of character vectors, or as a string. You can specify the
macrodefs
argument as multiple definitions within a single
character vector, for example '-DRT -DDEBUG'
. If you specify the
macrodefs
argument as multiple character vectors, for
example'-DPROTO -DDEBUG'
and '-DPRODUCTION'
, the
macrodefs
argument is added to the build information as an
array of character vectors.
Example: {'-DPROTO -DDEBUG' '-DPRODUCTION'}
groups
— Optional group name for the added compiler options
character vector | array of character vectors | string
You can specify the groups
argument as a character
vector, as an array of character vectors, or as a string. If you specify multiple
groups
, for example 'Debug' 'Release'
,
the function relates the groups
to the
macrodefs
in order of appearance. For example, the
macrodefs
argument {'-DPROTO -DDEBUG'
'-DPRODUCTION'}
is an array of character vectors with two elements. The
first element is in the 'Debug'
group and the second element is in
the 'Release'
group.
Note
The template makefile-based build process considers only macro definitions in the
'OPTS'
, 'OPT_OPTS'
,
'OPTIMIZATION_FLAGS'
, and 'Custom'
groups when
generating the makefile.
For the build process to consider definitions in other groups, the template
makefile must contain the token |>DEFINES_OTHER<|
.
Example: {'Debug' 'Release'}
