This unit will compile an ELF object file out of a supplied .res resource
file. Optionally, Delphi/Kylix dfm/xfm form files are also accepted as
input. These will automatically be converted into resources internally.
fpcres2elf builds with Delphi, Kylix and FPC.
Currently this only works on 32Bit targets, but support for 64Bit targets
is in the works. Support for big endian systems is completely missing,
though.
Format used for the various resource sections:
.fpc.resptrs: This section is contained in resptrs.o and always linked to the executable by
FPC. It containes an exported label fpcrespointers, which is used at runtime
to find the resptrs section in memory. The resptrs contains pointers to all the
sections and their sizes. These are updated in a post-precessing step by the
compiler and by the external resource embedder when applied to an ELF file.
This section always is 128 Bytes long and initially filled with zeros.
The first integer (32/64 Bit) value in this section contains the version
number of the resource system. Currently this value is 1.
The second integer (32/64 Bit) value in this section contains the number of
resources.
After this follows a version-defined number of TFPCResourceSectionInfo entries.
.fpc.ressym: Contains the resource names. This simply is a stream of zero-terminated strings.
Only textual names are supported, numeric IDs get autoconverted to #ID's.
The reshash table has got a byte index into ressym to quickly get that data if needed
.fpc.reshash: n TFPCResourceInfo records. (number of entries is defined in fpc.resptrs)
.fpc.resdata: Contains the plain resource data stream. A byte index into the data stream
is given for each resource entry in TResourceInfo
.fpc.resspare: An empty section which is resized to make room if the size of any of the previous
sections gets changed. NOT USED IN VERSION 1 (SIZE WILL BE 0)
.fpc.resstr: This section is completely seperated from the rest and contains a block of
resourcestrings in internal FPC format.
