Building CLDC Software on a Windows x86 Build Platform
Building a default version of CLDC creates the CLDC software executable cldc_vm.exe for the JavaCall porting layer on a Windows x86 target platform. To properly build the CLDC software on a Windows x86 build platform, you must set the environment variables shown in TABLE 4-1.
TABLE 4-1Required CLDC Build Variables for Windows x86
Name
Description
JVMWorkSpace
The location of your CLDC software source code workspace. For example, JVMWorkSpace=%COMPONENTS_DIR%/cldc.
JVMBuildSpace
The location of your CLDC software build output. For example, JVMBuildSpace=%BUILD_OUTPUT_DIR%/cldc.
ENABLE_PCSL
Required for building CLDC with the PCSL software component. Must be set to true.
PCSL_OUTPUT_DIR
The location of PCSL build output. Required for building CLDC if ENABLE_PCSL=true. For example, PCSL_OUTPUT_DIR=%BUILD_OUTPUT_DIR%/pcsl.
ENABLE_ISOLATES
Required for building a CLDC implementation with multitasking capability. Must be set to true. If not explicitly set to true, the build defaults to false and CLDC is built without multitasking capability.
Note: If you set ENABLE_ISOLATES=true to build a CLDC implementation with multitasking capability, you must also set USE_MULTIPLE_ISOLATES=true to build the phoneME Feature software, as described in Building a phoneME Feature Reference Port.
JAVACALL_OUTPUT_DIR
The location of JavaCall porting layer output. For example, JAVACALL_OUTPUT_DIR=%BUILD_OUTPUT_DIR%/javacall.
TOOLS_DIR
Defines the directory where needed build tools are located. For example, TOOLS_DIR=%COMPONENTS_DIR%/tools.
TOOLS_OUTPUT_DIR
Defines a directory location for tools-specific output. For example, TOOLS_OUTPUT_DIR=%BUILD_OUTPUT_DIR%/tools.
USE_VS2005
Tells the build system to use Microsoft Visual Studio 2005 as the default compiler. For example, USE_VS2005=true.
ENABLE_JAVA_DEBUGGER
Supports the use of the emulator binary plugin. For example, ENABLE_JAVA_DEBUGGER=true.
ENABLE_MULTIPLE_PROFILES_SUPPORT
Supports the use of the emulator binary plugin. For example, ENABLE_MULTIPLE_PROFILES_SUPPORT=true.
Building CLDC for a Windows x86 Target Platform
1. Set the JVMWorkSpace variable, as shown here.
$ set JVMWorkSpace=%COMPONENTS_DIR%/cldc
2. Set the JVMBuildSpace variable, as shown here.
$ set JVMBuildSpace=%BUILD_OUTPUT_DIR%/cldc
3. Run the make command as a single command-line string, as shown here.
$ make -C %JVMWorkSpace%/build/javacall_i386_vc ENABLE_PCSL=true PCSL_OUTPUT_DIR=%BUILD_OUTPUT_DIR%/pcsl ENABLE_ISOLATES=true JAVACALL_OUTPUT_DIR=%BUILD_OUTPUT_DIR%/javacall TOOLS_DIR=%COMPONENTS_DIR%/tools TOOLS_OUTPUT_DIR=%BUILD_OUTPUT_DIR%/tools USE_VS2005=true ENABLE_JAVA_DEBUGGER=true ENABLE_MULTIPLE_PROFILES_SUPPORT=true
The generated CLDC output is found under %JVMBuildSpace%/javacall_i386_vc/dist.
Running CLDC Software
Once you build the CLDC software, you can invoke it from the command line to run a class compiled from the Java programming language. The path to the executable depends on the target platform (operating system and processor) for which you build the software.
Running CLDC on a JavaCall porting layer on Windows x86 Target Platform
1. Change to the CLDC build space for the JavaCall porting layer on Windows x86 platform:
$ cd %JVMBuildSpace%/javacall_i386/dist
2. Enter the following command:
$ bin/cldc_vm.exe -classpath location-of-compiled-applications/classes classname
For example, to run the HelloWorld application:
$ bin/cldc_vm -classpath C:/src/classes HelloWorld
Building CLDC Documentation
You can create HTML documents from CLDC porting interfaces. To do this for the CLDC software, use the make docs_html build target.
Generating Javadoc Tool Documentation
Building Javadoc™ tool documentation is the same for all build platforms.
1. Change to the default build directory for your build platform.
For example, this could be a Linux on i386 platform, as shown here.
$ cd %JVMWorkSpace%/build/linux_i386
2. Build Javadoc tool HTML documentation.
$ make docs_html
Viewing phoneME Feature Documents
Use any browser to display the Javadoc tool output file at the following URL:
file://%JVMBuildSpace%/doc/javadoc/html/index.html
