Preparation +of the MMP and <filepath>bld.inf</filepath> Files

MMP +file

An .mmp project definition file +specifies the properties of a project in a platform and compiler-independent +way. The MMP file is very similar to ‘Makefile’ of Linux. MMP file exists +per .SO, .A, or .EXE.

The +contents of a sample MMP file created for libjpeg are shown +below:

TARGET libjpeg.dll +TARGETTYPE DLL +UID 0x1000008d 0x0xE0000100 +CAPABILITY All -Tcb +EpocAllowDllData + +USERINCLUDE . + +SYSTEMINCLUDE \epoc32\include\stdapis +SYSTEMINCLUDE \epoc32\include + +SOURCEPATH . +// LIBSOURCES +SOURCE jcapimin.c jcapistd.c jccoefct.c jccolor.c jcdctmgr.c jchuff.c +SOURCE jcinit.c jcmainct.c jcmarker.c jcmaster.c jcomapi.c jcparam.c +SOURCE jcphuff.c jcprepct.c jcsample.c jctrans.c jdapimin.c jdapistd.c +SOURCE jdatadst.c jdatasrc.c jdcoefct.c jdcolor.c jddctmgr.c jdhuff.c +SOURCE jdinput.c jdmainct.c jdmarker.c jdmaster.c jdmerge.c jdphuff.c +SOURCE jdpostct.c jdsample.c jdtrans.c jerror.c jfdctflt.c jfdctfst.c +SOURCE jfdctint.c jidctflt.c jidctfst.c jidctint.c jidctred.c jquant1.c +SOURCE jquant2.c jutils.c jmemmgr.c +// SYSDEPSOURCES +SOURCE jmemansi.c +LIBRARY euser.lib + +LIBRARY libc.lib +MACRO HAVE_CONFIG_H +MACRO __SYMBIAN32__

The following table gives a brief introduction +to the MMP file keywords found in above file.

+ + + +

Keyword

Description

+ + +TARGETTYPE +

Target type.Can be DLL, EXE, or LIB. Other types are also supported.

+ + +TARGET +

Name of the target.

+ + +UID +

Unique identifier of the target. It is recommended to use test UIDs +from the range 0xE0000000-0xEFFFFFFF which is targeted for +development use only. For production quality code, UIDs must be requested +from Symbian (https://www.symbiansigned.com/app/page) +before the application can be sent for signing.

+ + +CAPABILITY +

Capability requirement of the target.

Even if the example +uses All-TCB capabilities, it is strongly recommended to use a more narrow +set of capabilities to have the application successfully signed. + + +EpocAllowDllData +

Allow global static data in the target

+ + +USERINCLUDE +

Local file include path. The compiler will look in this path for +the files included with “ ”. For example, #include "config.h"

+ + +SYSTEMINCLUDE +

System file include path. The compiler will look in this path for +the files included with < >. For example, #include +<stdio.h>

+ + +SOURCEPATH +

Source path for the source files.

+ + +SOURCE +

Source file listing.

+ + +LIBRARY +

Dependent DLL library file list.

+ + +STATICLIBRARY +

Dependent static library file list.

+ + +MACRO +

Preprocessor declarations. Makefile declares these preprocessor +declarations using –D flag.

+ + + +

bld.inf

bld.inf is +a component definition file, used by bldmake to define the abld.bat file +and makefiles to be created. bld.inf can +be loosely compared to configure script of Linux. There is one bld.inf for +entire the OSS. If the project is divided into more than one module, each +module can have an individual bld.inf file. Have a look +at the contents of the sample MMP file below created for libjpeg.

PRJ_PLATFORMS +default + +PRJ_MMPFILES +jpeg.mmp + +PRJ_EXPORTS +jpeglib.h \epoc32\include\jpeg-6b\jpeglib.h +jconfig.h \epoc32\include\jpeg-6b\jconfig.h +jmorecfg.h \epoc32\include\jpeg-6b\jmorecfg.h +jerror.h \epoc32\include\jpeg-6b\jerror.h +

The following table gives a brief introduction to the bld.inf keywords.

Keyword

Description

+ + +PRJ_PLATFORMS +

Platform to which makefiles will be created.

+ + +PRJ_MMPFILES +

MMP file list.

+ + +PRJ_EXPORTS +

List of public header files for target library users. This list +can be prepared by looking at the include directory in Linux installation.
