| TWLSDK_ROOT NITROSDK_ROOT * Important |
Specifies the directory where the TWL-SDK is installed (the directory into which $TwlSDK is extracted).Default value: C:/TwlSDK
|
|||||||
|---|---|---|---|---|---|---|---|---|
| TWLSDK_PLATFORM * Important |
Specifies the build platform. Use this environment variable to compile only the code you need. For example, if you are using TWL-SDK to develop applications exclusively for TWL, set the environment variable TWLSDK_PLATFORM to TWL (TWLSDK_PLATFORM=TWL). The compiler will then generate TWL code only, not unneeded NITRO code.When not specified, the build will halt with an error.
|
|||||||
| CWFOLDER_TWL CWFOLDER_NITRO |
Specifies the CodeWarrior installation directory. CWFOLDER_NITRO will be configured automatically if CodeWarrior for NITRO is installed.When making this setting using cygwin bash, the directory must be enclosed in single quotes as follows. % export CWFOLDER_NITRO='D:/Program Files/Freescale/CW for NINTENDO DS V2.0' When making this setting using a Windows environment variable, the specification takes the following form. D:/Program Files/Freescale/CW for NINTENDO DS V2.0Both / and \ are accepted as path delimiters. Default value: None (Usually set when CodeWarrior is installed) |
|||||||
| LM_LICENSE_FILE | Specifies the license file path for CodeWarrior. Default value: None (Usually set when CodeWarrior is installed) |
|||||||
| IS_TWL_DEBUGGER_DIR IS_NITRO_DIR |
This is the IS-TWL-DEBUGGER installation folder. It is automatically set when IS-TWL-DEBUGGER is installed. If this environment variable exists, the IS-TWL-DEBUGGER-related libraries will be linked automatically. Default value: None (Usually set when IS-TWL-DEBUGGER is installed) |
TwlSDK tree are shown below. Normally, these values are set by specifying them as parameters to the make command (for example, make TWL_DEBUG=TRUE) and including them within makefiles. However, they can also be set as individual environment variables. The default value is used if a variable is undefined. For more information about where each build switch can be set, see the Build Switch Usage Table.TWL_*) will be given priority if changes are made to the following environment variables. (If TWL_PROC=ARM9 and NITRO_PROC=ARM7 are both present within a makefile, TWL_PROC is set to ARM9.)| TWL_PROC NITRO_PROC * No change necessary |
Sets which processor code should be generated for the ARM9 (main processor) and the ARM7 (subprocessor). Use the default value.
| ||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| TWL_ARCHGEN | For TWL code, sets whether to generate TWL-exclusive code or NITRO/TWL hybrid code. This build switch can be set with the build system. Specifically, set whether LIMITED or HYBRID code should be built. Reference this build switch in the makefile after commondefs.
| ||||||||||||
| TWL_CODEGEN NITRO_CODEGEN |
Sets whether binary code generated by the compiler and assembler should use the ARM or Thumb instruction set. If there is no explicit setting in the source, the compiler and assembler generate the code according to these values. Reference this build switch value in the makefile after commondefs.
| ||||||||||||
| TWL_DEBUG TWL_RELEASE TWL_FINALROM NITRO_DEBUG NITRO_RELEASE NITRO_FINALROM * Important |
Select from the following build types: DEBUG, RELEASE, and FINALROM.When the make command is executed, the compile options and the linked libraries will change according to this setting.Unlike other variables, this variable is specified by setting one of the build types to TRUE. See $TwlSDK/man/en_US/information/compiletarget.html (compile target explanation) for more information about these three types.Default value: When not specified, the RELEASE version will be built. | ||||||||||||
| TWL_STD_PCHDR TWL_NO_STD_PCHDR NITRO_STD_PCHDR NITRO_NO_STD_PCHDR |
When a value is set for TWL_STD_PCHDR, the build system precompiles $TwlSDK/include/twl.h and loads the result during the build. This should result in a faster build. To temporarily suppress this compile, set a value for TWL_NO_STD_PCHDR.Default value: TWL_STD_PCHDR=True |
||||||||||||
| TWLSDK_LANG NITROSDK_LANG |
You can switch the TwlSDK compile options between Japanese and English.For Japanese, the -enc SJIS option will be set. For English, the -enc ascii option will be set.
| ||||||||||||
| TWL_ROMSPEED NITRO_ROMSPEED |
When the default RSF file is used, the RomSpeedType parameter in the Property section is assigned a value. The value of the MAKEROM_ROMSPEED symbol passed to the makerom.TWL.exe tool is used. When an original file is used instead of the default RSF file, it is ignored. For information on the RomSpeedType parameter, see the documentation for the makerom.TWL.exe tool. MROM cannot be used with TWL.
|
||||||||||||
| TWL_COMPRESS NITRO_COMPRESS * Important |
When a value is specified, the STATIC/OVERLAY segment is compressed after the link is completed. Default value: None (no compression) |
||||||||||||
| TWL_DIGEST NITRO_DIGEST |
This build switch is enabled only for applications. It is disabled when building the SDK. If a value is set, code for a DS Single-Card Play child program that uses overlays will be built. Default value: None |
||||||||||||
| TWL_PROFILE NITRO_PROFILE |
If a value is set, the -profile option is added when compiling. This is primarily used during debugging so that input and output of each function can be traced during execution.For additional details, see the OS_DumpCallTrace function.Default value: None ( -profile option is disabled) |
||||||||||||
| TWL_MEMSIZE NITRO_MEMSIZE * No change necessary |
Specifies the main memory size of TWL compile targets. This build switch specification method was retained for backward compatibility. Because it does not require you to rebuild the SDK, we recommend using OS_EnableMainExArena instead. Use the default value.
|
||||||||||||
| TWL_NO_OPT_G NITRO_NO_OPT_G |
When a value is set, the -g option used to specify normal compilation and linking is removed.Expect a reduction in linking times, which can be an issue in large projects. Default value: None (-g option enabled) |
||||||||||||
| TWL_SVC_WAITVBLANK_COMPATIBLE NITRO_SVC_WAITVBLANK_COMPATIBLE |
Define this to NOT automatically replace the SVC_WaitVBlankIntr function call with the OS_WaitVBlankIntr function call. Note that the SVC_WaitVBlankIntr function will not release the resource to a low-priority thread. Depending on how this is used, some problems may occur. If a system call must be used as it was previously, it should only be used after thorough verification.Note: This replacement is made using a #define statement inside a header file, so it will be valid only after the TWL-SDK is rebuilt. If these environment variables are defined with make, SDK_SVC_WAITVBLANK_COMPATIBLE will be defined, and you can find it in the source through #ifdef/#endif statements.This is not defined by default, so the SVC_WaitVBlankIntr function call is automatically replaced with the OS_WaitVBlankIntr function call. Default value: None
|
||||||||||||
| CW_LIBFP | Specify one of the following floating-point libraries to the CodeWarrior compiler. If nothing is specified, the first value shown in the following list is used. For details on the differences in performance between the libraries, see the CodeWarrior reference.
| ||||||||||||
| TARGET_PLATFORM * Important |
Sets whether to include the makefile for the build platform. For example, to build a demo only for TWL, include TARGET_PLATFORM=TWL in the makefile. This will cause the demo to be built only in TWL mode, and will prevent it from being built in NITRO mode.If this setting is not present in a makefile, code is generated for every build.
|
||||||||
|---|---|---|---|---|---|---|---|---|---|
| TWL_BUILD_TYPE NITRO_BUILD_TYPE Overwriting prohibited |
DEBUG, RELEASE, or FINALROM is set as the target build type.To reference the build type set in the makefile, reference this variable after commondefs. | ||||||||
| DEFAULT_COMP_ARM7 * Important |
The ARM7 component to be used is configured within the makefile. For more information on ARM7 components, see $TwlSDK/docs/TechnicalNotes/AboutComponents.pdf.
|
||||||||
| SUBDIRS * Important |
Enumerates the directories you want the make process to concatenate. Default value: None |
||||||||
| SUBMAKES | Enumerates the makefiles you want the make process to concatenate. Default value: None |
||||||||
| SRCS * Important |
Enumerates the source files you want to compile and assemble. The make command tries to generate an object file with the compiler or assembler of the programming language shown in the following table, according to the extension of each file.
|
||||||||
| SRCS_OVERLAY For overlay |
Enumerates the source files you want to compile and assemble. The object files generated from the files specified here are registered as belonging to an OVERLAY group. |
||||||||
| SRCDIR | Specifies the source-file directory. Default value: ./src (Indicates a relative path to src from the make directory) |
||||||||
| INCDIR |
Specifies the directory if there are private include files (module-specific include files). Default value: ./include |
||||||||
| OBJDIR BINDIR LIBDIR Rewrite prohibited |
Specifies the directory where the make command outputs temporary files.This specification is used often in a source tree, so be careful changing the assignment in individual directories. |
||||||||
| LCFILE | Specifies your own link command file (.lcf).Default value: $TwlSDK/include/nitro/ARM9.TS.lcf |
||||||||
| LCFILE_SPEC | Specify the configuration file to use as the base to automatically generate a link command file with the makelcf command.Default value: Unspecified |
||||||||
| ROM_SPEC | Specifies the file that describes the contents of the ROM file. This file will be passed to the makerom command, and the ROM will be generated based on the configuration of this file. |
||||||||
| TARGET_BIN * Important |
Specifies a target file in SRL or TEF format. It compiles or assembles the source files specified by SRCS and links the resulting object files, making them the target files. A TEF file will be created automatically if an SRL file is specified as the target. The following values cannot be set for this variable.
|
||||||||
| TARGET_LIB | Specify this to create a library file. It compiles or assembles the source files specified by SRCS and links the resulting object files, making them a library. Normally, TARGET_BIN and TARGET_LIB are not configured at the same time. |
||||||||
| TARGET_OBJ | Specify this to create an object file as a target. This is not normally used. In the library, this is used when crt0.c is compiled and installed as a library. |
||||||||
| TARGETS Rewrite prohibited |
Targets to which the relative path was added to TARGET_BIN and TARGET_LIB are set up automatically.The storage directories for .srl and .a files change depending on the TWL_PLATFORM and TWL_DEBUG/TWL_RELEASE/TWL_FINALROM settings.This macro was prepared to absorb this change. |
||||||||
| INSTALL_TARGETS | Enumerates the files you want to install. The TARGETS described above will function in this setting. Default value: None |
||||||||
| INSTALL_DIR | Specifies the installation directory. Default value: None |
||||||||
| LINCLUDES | Specifies the directory if there are other include files. Default value: None |
||||||||
| LLIBRARY_DIRS LLIBRARIES |
If there are other library files, this enumerates their directory with LLIBRARY_DIRS and the library files with LLIBRARIES. |
||||||||
| LDIRT_CLEAN LDIRT_CLOBBER |
Specifies the files to delete along with object files when executing the make clean or make clobber command.With make clean, all files specified with LDIRT_CLEAN are deleted. With make clobber, all files specified with LDIRT_CLEAN and LDIRT_CLOBBER are deleted. |
||||||||
| MAKELCF_FLAGS | Define this build variable when you want to give your own additional run options to makelcf. Default value: None |
||||||||
| MAKEROM_FLAGS | Define this build variable when you want to give your own additional run options to makerom. Default value: None |
||||||||
| FORCE_DISABLE_IS_NITRO_DEBUGGER |
Although debugging features are not available when using IS-NITRO-DEBUGGER or IS-NITRO-EMULATOR, this option conserves the amount of memory used. Define only when debugging with IS-TWL-DEBUGGER (software/hardware). No default value is defined. This allows for all debugging features installed on the build PC to be used. Default value: None |
