BUILDROM - ROM configuration tool V$BuildromMajorVersion.$BuildromMinorVersion.$BuildromPatchVersion

Usage:

  buildrom [options] obyfile [obyfile2 ...]   

Build a ROM according to the specification defined by concatenating the

specified obyfiles.

The initial specification is modified by C++ preprocessor directives,

and subsequently adjusted by statements in the ROM specification language.

The final specification is in the subset of the specification language

which is understood directly by ROMBUILD.

Each obyfile parameter specifies a file via a search path: if the

filename is not matched then buildrom will look in \\epoc32\\rom\\include.

Buildrom invokes ROMBUILD to generate the ROM image, and produces a

number of related files such as the ROM symbol file. The name of the

image file is specified directly by the -o option, or determined by 

scanning the final specification for the "romname" keyword. If there is 

more than one "romname" statement, the last one takes precedence.

The available options are

   -Dxxx                            -- C++ preprocessor arguments

   -oimagename                      -- ROM image name, overriding any ROMNAME statement

   -s                               -- strict option, any missing files will stop buildrom 

   -p                               -- preserves the intermediate files pertaining to data drive, Z drive and BMCONV

   -spi                             -- enable producing SPI files

   -spiplacement                    -- enable positioning of spi file

   -w                               -- warn if file has been selected from a different directory 

   $featuresOptionUsage

   -etool                           -- external tool specification (xx is tool's perl module)

   -compress                        -- compression type of ROM image:

                                       -compress compress whole ROM image.

                                       -compress=paged compress paged section in the ROM image only.

                                       -compress=unpaged compress unpaged section in the ROM image only. 

   -ccomprmethod                    -- compression method: none|inflate|bytepair

   -geninc                          -- generate INC file

   -gendep                          -- generate dependence graph for rom image

   -nosymbols                       -- disable creation of symbol file

   -noimage                         -- disable creation of ROM/ROFS/DataDrive Image

   -fastcompress                    -- compress files with faster bytepair and tradeoff of compress ratio

   -j<digit>                        -- do the main job with <digit> threads

   -loglevel<level>                 -- Level of information logging where loglevel is 0,1,2

                                       0 default level of information

                                       1 host/ROM filenames, file size and the hidden attribute along with level0 log

                                       2 E32 file header attributes along with level1 log

   -z=xxx or -zdrivepath=xxx        -- specify a location to create Z drive directory. 

   -d=xxx or -datadrivepath=xxx     -- specify a location to create data drive directory.

   -k or -keepgoing                 -- enable keepgoing,continue to create the data drive image even

                                    if the non-sis, sis or zdrive image file(s) are missing or corrupt.

   -r or -retainfolder              -- enable retainfolder,would retain pre-existence of z & data drive folder. 

   -zdriveimage=xxx                 -- specify Z drive image (ROM, CORE, ROFS or Ext-ROFS image).

   -pfile=xxx                       -- specify a parameter file for interpretsis to take additional parameters.

   -argforinterpretsis=xxx          -- specify command line argument(s) for interpretsis which will override the 

                                    parameter file contents.

   -l=xxx or -logimagecontents=xxx  -- extract all stub-sis and SWI certificate store file(s) only 

                                    and log all the file(s) that are part of the Z drive image on to a log file.  

   -I<directory>                    -- Use <directory> for the referenced IBY/OBY files

   -argfile=xxx                     -- specify argument-file name containing list of command-line arguments to buildrom   

   -lowmem                          -- use memory-mapped file for image build to reduce physical memory consumption   

Popular -D defines to use include

   -D_DEBUG         -- select debug versions of some files

   -D_FULL_DEBUG    -- select debug versions of all files

   -D_ARM4          -- specify the target platform

   -D_EABI=xxxx     -- specify target for all files (e.g. ARMV5)

   -D_KABI=xxxx     -- specify the target platform for the Kernel (e.g. ARMV5)

Other defines may be useful for particular OBY files.
