Usage of XAR
Building libraries with XAR is quite simple, just type either:
xar file1 file2 ... fileN -o lib
or
xar lib file1 file2 ... fileN
This will make XAR create a library called lib that consists of the
files file1 to fileN.
XAR options
Aside from -o XAR has the following options:
-S Silent operation, nothing is printed if
everything went well, this is the default setting for
command line XAR.
-V Verbose, this prints the progress of XAR while it builds
libraries, this is the default setting for the XAR used by
the IAR Embedded Workbench.
-x filename, this extends the command line with the contents
of the file 'filename'. See
The Extended Command Line file for the details.
XAR Extended Command Line File
XAR can read command files using the -x
option. The main reason for this is that large libraries
sometimes requires so many files the command line becomes larger
than the buffer allocated by the process XAR is run from. Note
that this is a limitation in the OS/shell, not a limitation in
XAR.
The command file may only contain file names, white spaces
and comments, not options. All options must be specified on
the command line.
- White spaces at the beginning of a line are ignored.
- All characters between an occurence of "//" and the next
newline are ignored.
- All other characters are considered to be part of a file name.
Once a non white space character has been encountered, the rest
of the line will be considered a file name or a comment.
Warning codes in XAR
- 0 File 'filename' has already been added to the library
- The file was added to the library before the processing of this
file. This is almost certainly an error as all symbols in the
file will be multiply defined.
Error codes in XAR
As simple as XAR is, sometimes something goes wrong. This is a list of
the possible errors that XAR detects:
- 0 Not enough memory
- XAR was unable to aquire the memory that it needed.
- 1 -o option requires an argument
- XAR expects an argument after -o.
- 2 Unknown option 'option'
- XAR encountered an unknown option on the command line.
- 3 Too few arguments
- XAR expects to find more arguments
- 4 Same file as both input and output: 'filename'
- One of the files is used as both input and output,
as this would destroy an infile it is forbidden. If you really
want to give the new library a name that is used by one of the
infiles you will have to use a temporary file to build the
library with XAR and rename that temporary file to the name
you want afterwards.
- 5 Can't open library file 'filename' for writing
- XAR was unable to open the library file for writing, the
most probable explanation for this is that the library file
is write protected.
- 6 Can't open object file 'filename'
- XAR was unable to open the object file, the most probable
explanation for this is that the file does not exist.
- 7 Error occured while writing to library file
- An error ocurred while XAR was writing to the file.
- 8 'filename' is not a valid UBROF file
- The file is not a valid UBROF file.
- 9 Error occured while reading from 'filename'
- An error ocurred while XAR was reading the file.
- 10 Error occured while closing 'filename'
- An error ocurred while XAR was closing the file.
- 11 XAR didn't find any bytes to read, is 'filename'
empty ?
- The object file seems to be empty. Note that this error
only can occur in older versions of XAR.
- 12 'filename' didn't end as a valid UBROF file
should
- The file did not end as a UBROF file is supposed to end.
Either the file is corrupt or the assembler / compiler
produces corrupt output.
- 13 XAR can't fseek in library file
- The call to fseek failed.
- 14 -x option requires an argument
- You need to specify an argument for the -x option
- 15 A file name in the file `file` exceeds the maximum
file name length of number characters.
- A file name in the extended command line file is too
long. The only recognized delimiter in the input file is
newline, everything else is interpreted as a part of the
file name.
Note: XAR does not distinguish between UBROF for different processors,
as far as it is concerned a UBROF file is a UBROF file and if a user
wants to build a library consisting of files from two different cpu:s
it allows it.
