Compilation -and Build Process on Symbian Platform

The bldmake tool processes the component description file bld.inf in -the current directory and generates the batch file abld.bat and -several build batch makefiles (.make) -. The makefiles are used by abld to carry -out the various stages of building the component.

This enables the programmer to build for different platforms with varied -specifications. The parameter command specifies which action to perform to -the abld tool. The actions can be build, clean, cleanexport and -so on. The parameter options includes –c, -w and -so on, these enable the user to check for the presence of releasables. The -parameter platform specifies the platform for which the project will be built. -The platform can be WINSCW, GCCE, GCCXML, EDG, ARMV5, VS6, CW_IDE or VS2003. The parameter -build specifies whether to build for debug (udeb) or release -(urel) version. Finally the parameter program specifies which -project definition file or mmp file to build. If left unspecified, all the -MMP files mentioned in the bld.inf file are built. For -more information, see Build -tools reference.

The abld freeze command freezes the project export. -This is needed only for DLLs.

Creating -PKG file and Installation file for the target

A package (PKG) file -is a text file containing items or statements that define the information -required by the installation (SIS) file creation utility makesis. -The PKG file format can be broken down into the following items:

Languages
Language code table
Package-header
Vendor
Logo
Package-signature
Package-body
Dependency
Properties

For more information on PKG files, see PKG -File Format.

The makesis utility creates software -installation packages (SIS files) based on the information and the file locations -on the source PC or target phone, defined in a package (PKG) file.

For -example, consider the code snippet given below:

makesis somefile.pkg

The -code goes through the PKG file and by default creates somefile.sis in the -directory where the PKG file is present.

For more information on the makesis utility, -see MakeSIS.

After -creating the SIS file it, has to be signed using signsis to -install it on the phone. signsis is a Symbian supplied -tool to digitally sign software installation (SIS) files using a specified -certificate and private key. For example consider the code snippet given below:

signsis somefile.sis somefile.sisx rd.cer rd-key.pem

The parameter somefile.sis gives, the path to the -SIS file which is to be signed. The second parameter, somefile.sisx specifies -the name of the resultant signed SIS file. The third parameter, rd.cer specifies -the path to the certificate file and the last parameter, rd-key.pem specifies -the path to the file containing the private key.

For more information -on signsis, see SignSIS.
