| TWLSDK_ROOT (NITROSDK_ROOT) * Important |
Directory where the TWL-SDK is installed (the directory into which $TwlSDK is extracted).Default value: C:/TwlSDK
|
|||||||
|---|---|---|---|---|---|---|---|---|
| TWLSDK_PLATFORM * Important |
Platform to build for. By using this environment variable, you can compile for only the desired platform. For example, if developing only TWL applications with TWL-SDK, set the environment variable to " TWLSDK_PLATFORM=TWL". Doing so causes the compiler to generate code only for TWL, without generating any unnecessary NITRO code.When not specified, the build halts with an error.
|
|||||||
| CWFOLDER_TWL (CWFOLDER_NITRO) |
Directory where CodeWarrior is installed. If you install CodeWarrior for NITRO, CWFOLDER_NITRO is configured automatically.When making this setting with Cygwin bash, you must enclose the directory in single quotes as follows. % export CWFOLDER_NITRO='D:/Program Files/Freescale/CW for NINTENDO DS V2.0' When making this setting with a Windows environment variable, the specification takes the form given below. D:/Program Files/Freescale/CW for NINTENDO DS V2.0Both / and \ work as path delimiters. Default value: None (This value is normally set when CodeWarrior is installed.) |
|||||||
| LM_LICENSE_FILE | License file path for CodeWarrior. Default value: None (This value is normally set when CodeWarrior is installed.) |
|||||||
| IS_TWL_DEBUGGER_DIR (IS_NITRO_DIR) |
Installation folder for IS-TWL-DEBUGGER-related files. It is automatically set when IS-TWL-DEBUGGER is installed. If this environment variable exists, the IS-TWL-DEBUGGER-related libraries are linked automatically. Default value: None (This value is normally set when CodeWarrior is installed.) |
make command (for example, make TWL_DEBUG=TRUE) and including them in makefiles, though they can also be set with standard environment variables. The default values are used if a setting is missing. For more information about the ranges in which each build switch can be set, see the Build Switch Usage Table.TWL_*) are given priority if changes are made to the environment variables below. (If TWL_PROC=ARM9 and NITRO_PROC=ARM7 are both listed in the makefile at the same time, TWL_PROC is set to ARM9.))| TWL_PROC (NITRO_PROC) * No change necessary |
Sets which processor to generate code for: the ARM9 (main processor), or the ARM7 (subprocessor). Use the default value unchanged.
| ||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| TWL_ARCHGEN | For TWL code, sets whether to generate TWL-exclusive code or NITRO/TWL hybrid code. This build switch may be rewritten in the build system. Specifically, this sets whether limited or hybrid code is being built. If you want to reference this build switch in the makefile, do so 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 this is not set explicitly in the source code, the code is generated according to this setting. If you want to reference the value set for this build switch in the makefile, do so after commondefs.
| ||||||||||||
| TWL_DEBUG (NITRO_DEBUG) TWL_RELEASE (NITRO_RELEASE) TWL_FINALROM (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 change according to this setting.Unlike other variables, this variable is enabled by setting it to one of the three values (such as TRUE). See $TwlSDK/man/en_US/information/compiletarget.html (Description of Compile Targets) for more information about these three options.Default value: When not specified, the RELEASE version is built. | ||||||||||||
| TWL_STD_PCHDR (NITRO_STD_PCHDR) TWL_NO_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 file build. This should result in a faster build. To temporarily suppress this compile, set a value in TWL_NO_STD_PCHDR.Default value: TWL_STD_PCHDR=True |
||||||||||||
| TWLSDK_LANG (NITROSDK_LANG) |
Switches the TWL-SDK compile options between Japanese and English. For Japanese, the -enc SJIS option is set. For English, the -enc ascii option is set.
| ||||||||||||
| TWL_ROMSPEED (NITRO_ROMSPEED) |
When you use the default RSF file, this assigns the specified value to the RomSpeedType parameter in the Property section. Specifically, the value of the MAKEROM_ROMSPEED symbol passed to the makerom.TWL.exe tool is used. When you use an original file instead of the default RSF file, this 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 some value is specified here, the STATIC and OVERLAY segments are compressed after linking. Default value: None (no compression) |
||||||||||||
| TWL_DIGEST (NITRO_DIGEST) |
This build switch is enabled only for applications. It is ignored when building the SDK. If some value is set here, the application is built as a DS Download Play child program that uses overlays. Default value: None. |
||||||||||||
| TWL_PROFILE (NITRO_PROFILE) |
If some value is set here, the -profile option is added when compiling. This is primarily used with DEBUG builds so that input and output of each function can be traced when the application runs.For details of use, 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. Specifying this with a build switch is the old method, which was retained for backward compatibility. The current, more convenient method is to use the OS_EnableMainExArena function instead. We recommend the current method because it does not require you to rebuild the SDK.Use the default value unchanged.
|
||||||||||||
| TWL_NO_OPT_G (NITRO_NO_OPT_G) |
When some value is set here, the -g option specified during normal compilation and linking is removed. Programmers can expect a reduction in linking times that become an issue in large projects. Default value: None ( -g option enabled) |
||||||||||||
| TWL_SVC_WAITVBLANK_COMPATIBLE (NITRO_SVC_WAITVBLANK_COMPATIBLE) |
Define this when you do not want to automatically replace SVC_WaitVBlankIntr function calls with OS_WaitVBlankIntr function calls. However, by specification the SVC_WaitVBlankIntr function does not release resources to low-priority threads, and that may cause problems depending on how the function is used. If you absolutely must use the old system calls, you should do so only after thorough verification.Note: This replacement is made using a #define statement inside a header file, so it is valid only after the TWL-SDK is rebuilt.If this environment variable is defined during make, SDK_SVC_WAITVBLANK_COMPATIBLE is defined, and you can find it in the source through #ifdef/#endif statements.This switch is not defined by default, so SVC_WaitVBlankIntr function calls are automatically replaced with OS_WaitVBlankIntr function calls.Default value: None |
||||||||||||
| CW_LIBFP | Specify any one of the following floating-point libraries to the CodeWarrior compiler. If nothing is specified, the default value is used. For details on the differences in performance between the libraries, see the CodeWarrior reference.
| ||||||||||||
| TARGET_PLATFORM * Important |
In the makefile, sets whether to actually perform the build based on the build target platform. For example, to create a demo that you want to build only in TWL mode, include TARGET_PLATFORM=TWL in the makefile for that demo. This builds the demo only in TWL mode, and prevents it from being built in NITRO mode.If this setting is not present in a makefile, there are no restrictions on the platforms for which code is generated.
|
||||||||
|---|---|---|---|---|---|---|---|---|---|
| TWL_BUILD_TYPE NITRO_BUILD_TYPE Rewriting Prohibited |
The target build type is set here as DEBUG, RELEASE, or FINALROM. If you want to reference the build type in the makefile, reference this variable after commondefs. | ||||||||
| DEFAULT_COMP_ARM7 * Important |
Sets in the makefile what ARM7 components to use. 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 by 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 directory for source code files. Default value: ./src (This default value represents the directory specified by src as a relative path from the directory in which make was executed.) |
||||||||
| INCDIR |
Specifies the directory of any private include files (module-specific include files). Default value: ./include |
||||||||
| OBJDIR BINDIR LIBDIR Rewriting Prohibited |
Specifies the directory where the make command outputs temporary files.Because this directory may change to accommodate the source tree, avoid overwriting this in the makefiles in individual directories. |
||||||||
| LCFILE | Specify this to use your own link command file (LCF). Default value: $TwlSDK/include/nitro/ARM9.TS.lcf |
||||||||
| LCFILE_SPEC | Specifies the configuration file to use as the base when automatically generating link command files with the makelcf command.Default value: Not specified |
||||||||
| ROM_SPEC | Specifies the file that describes the contents of the ROM file. This file is passed to the makerom command, and the ROM is 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 is 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 Rewriting Prohibited |
When this is specified, items appended with relative paths are configured automatically in TARGET_BIN and TARGET_LIB.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 setting described above is valid to specify here.Default value: None |
||||||||
| INSTALL_DIR | Sets the installation directory. Default value: None |
||||||||
| LINCLUDES | Specifies the directory of any other include files. Default value: None |
||||||||
| LLIBRARY_DIRS LLIBRARIES |
If there are other library files, this enumerates their directories with LLIBRARY_DIRS and the library files with LLIBRARIES. |
||||||||
| LIBSYSCALL | Specifies the libsyscall to use.Default value: $TwlSDK/lib/ARM9-TS/etc/libsyscall.a |
||||||||
| LIBSYSCALL_TWL | Specifies the libsyscall to use for [HYBRID/LIMITED] ROM.Default value: $TwlSDK/lib/ARM9-TS/etc/libsyscall.twl.a |
||||||||
| LDIRT_CLEAN LDIRT_CLOBBER |
Specifies the file(s) 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 this option disables the IS-NITRO-DEBUGGER and IS-NITRO-EMULATOR debugging features, it conserves the amount of memory used. Define this when you will debug only with IS-TWL-DEBUGGER (software/hardware). This is not defined by default, so by default all debugging features of all debuggers installed on the build PC are available. Default value: None. |
