bld.inf FilesAt the end of this phase, Symbian port should have the bld.inf and
MMP files.
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:

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 |
CAPABILITY |
Capability requirement of the target. Note: 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, |
SYSTEMINCLUDE |
System file include path. The compiler will look in this path for
the files included with |
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 |
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.
