Description

This program generates the dictionaries needed for performing I/O of classes.

Options

-f

Overwrite an existing output file

The output file must have the .cxx, .C, .cpp, .cc or .cp extension.

-v

Display all messages

-v0

Display no messages at all

-v1

Display only error messages

-v2

Display error and warning messages (default).

-v3

Display error, warning and note messages

-v4

Display all messages

-m

Specify absolute or relative path Clang pcm file to be loaded

The pcm file (module) produced by this invocation of rootcling

will not include any of the declarations already included in the

pcm files loaded via -m.  There can be more than one -m

-rmf

Rootmap file name

Name of the rootmap file. In order to be picked up by ROOT it must

have .rootmap extension

-rml

Rootmap library name

Specify the name of the library which contains the autoload keys. This

switch can be specified multiple times to autoload several libraries in

presence of a particular key

-split

Split the dictionary

Split the dictionary in two, putting the ClassDef functions in a separate

file

-s

Target library name

The flag -s must be followed by the name of the library that will

contain the object file corresponding to the dictionary produced by

this invocation of rootcling.

The name takes priority over the one specified for the rootmapfile.

The name influences the name of the created pcm:

  1) If it is not specified, the pcm is called libINPUTHEADER_rdict.pcm

  2) If it is specified, the pcm is called libTARGETLIBRARY_rdict.pcm

     Any "liblib" occurence is transformed in the expected "lib"

  3) If this is specified in conjunction with --multiDict, the output is

     libTARGETLIBRARY_DICTIONARY_rdict.pcm

-multiDict

Enable support for multiple pcms in one library

Needs the -s flag. See its documentation.

-inlineInputHeader

Add the argument header to the code of the dictionary

This allows the header to be inlined within the dictionary

-interpreteronly

No IO information in the dictionary

-noIncludePaths

Do not store the headers' directories in the dictionary

Instead, rely on the environment variable $ROOT_INCLUDE_PATH at runtime

-excludePath

Specify a path to be excluded from the include paths

specified for building this dictionary

--lib-list-prefix

Specify libraries needed by the header files parsed

This feature is used by ACliC (the automatic library generator).

Rootcling will read the content of xxx.in for a list of rootmap files (see

rlibmap). Rootcling will read these files and use them to deduce a list of

libraries that are needed to properly link and load this dictionary. This

list of libraries is saved in the first line of the file xxx.out; the

remaining lines contains the list of classes for which this run of

rootcling produced a dictionary
