TSystem Class Reference

Abstract base class defining a generic interface to the underlying Operating System.

This is not an ABC in the strict sense of the (C++) word. For every member function there is an implementation (often not more than a call to AbstractMethod() which prints a warning saying that the method should be overridden in a derived class), which allows a simple partial implementation for new OS'es.

int TSystem::CompileMacro ( const char *  filename,
Option_t opt = "",
const char *  library_specified = "",
const char *  build_dir = "",
UInt_t  dirmode = 0 
)
virtual

This method compiles and loads a shared library containing the code from the file "filename".

The return value is true (1) in case of success and false (0) in case of error.

The possible options are:

  • k : keep the shared library after the session end.
  • f : force recompilation.
  • g : compile with debug symbol
  • O : optimized the code
  • c : compile only, do not attempt to load the library.
  • s : silence all informational output
  • v : output all information output
  • d : debug ACLiC, keep all the output files.
  • - : if buildir is set, use a flat structure (see buildir below)

If library_specified is specified, CompileMacro generates the file "library_specified".soext where soext is the shared library extension for the current platform.

If build_dir is specified, it is used as an alternative 'root' for the generation of the shared library. The library is stored in a sub-directories of 'build_dir' including the full pathname of the script unless a flat directory structure is requested ('-' option). With the '-' option the libraries are created directly in the directory 'build_dir'; in particular this means that 2 scripts with the same name in different source directory will over-write each other's library. See also TSystem::SetBuildDir.

If dirmode is not zero and we need to create the target directory, the file mode bit will be change to 'dirmode' using chmod.

If library_specified is not specified, CompileMacro generate a default name for library by taking the name of the file "filename" but replacing the dot before the extension by an underscore and by adding the shared library extension for the current platform. For example on most platform, hsimple.cxx will generate hsimple_cxx.so

It uses the directive fMakeSharedLibs to create a shared library. If loading the shared library fails, it tries to output a list of missing symbols by creating an executable (on some platforms like OSF, this does not HAVE to be an executable) containing the script. It uses the directive fMakeExe to do so. For both directives, before passing them to TSystem::Exec, it expands the variables $SourceFiles, $SharedLib, $LibName, $IncludePath, $LinkedLibs, $DepLibs, $ExeName and $ObjectFiles. See SetMakeSharedLib() for more information on those variables.

This method is used to implement the following feature:

Synopsis:

The purpose of this addition is to allow the user to use an external compiler to create a shared library from its C++ macro (scripts). Currently in order to execute a script, a user has to type at the root prompt

.X myfunc.C(arg1,arg2)

We allow them to type:

.X myfunc.C++(arg1,arg2)

or

.X myfunc.C+(arg1,arg2)

In which case an external compiler will be called to create a shared library. This shared library will then be loaded and the function myfunc will be called with the two arguments. With '++' the shared library is always recompiled. With '+' the shared library is recompiled only if it does not exist yet or the macro file is newer than the shared library.

Of course the + and ++ notation is supported in similar way for .x and .L.

Through the function TSystem::SetMakeSharedLib(), the user will be able to indicate, with shell commands, how to build a shared library (a good default will be provided). The most common change, namely where to find header files, will be available through the function TSystem::SetIncludePath(). A good default will be provided so that a typical user session should be at most:

root[1] gSystem->SetIncludePath("-I$ROOTSYS/include
-I$HOME/mypackage/include");
root[2] .x myfunc.C++(10,20);

The user may sometimes try to compile a script before it has loaded all the needed shared libraries. In this case we want to be helpfull and output a list of the unresolved symbols. So if the loading of the created shared library fails, we will try to build a executable that contains the script. The linker should then output a list of missing symbols.

To support this we provide a TSystem::SetMakeExe() function, that sets the directive telling how to create an executable. The loader will need to be informed of all the libraries available. The information about the libraries that has been loaded by .L and TSystem::Load() is accesible to the script compiler. However, the information about the libraries that have been selected at link time by the application builder (like the root libraries for root.exe) are not available and need to be explicitly listed in fLinkedLibs (either by default or by a call to TSystem::SetLinkedLibs()).

To simplify customization we could also add to the .rootrc support for the variables

Unix.*.Root.IncludePath: -I$ROOTSYS/include
WinNT.*.Root.IncludePath: -I%ROOTSYS%/include
Unix.*.Root.LinkedLibs: -L$ROOTSYS/lib -lBase ....
WinNT.*.Root.LinkedLibs: %ROOTSYS%/lib/*.lib msvcrt.lib ....

And also support for MakeSharedLibs() and MakeExe().

(the ... have to be replaced by the actual values and are here only to shorten this comment).

Int_t TSystem::RedirectOutput ( const char *  name,
const char *  mode = "a",

virtual

Redirect standard output (stdout, stderr) to the specified file.

If the file argument is 0 the output is set again to stderr, stdout. The second argument specifies whether the output should be added to the file ("a", default) or the file be truncated before ("w"). The implementations of this function save internally the current state into a static structure.

The call can be made reentrant by specifying the opaque structure pointed by 'h', which is filled with the relevant information. The handle 'h' obtained on the first call must then be used in any subsequent call, included ShowOutput, to display the redirected output. Returns 0 on success, -1 in case of error.

If isflast is flase, then the libraries are actually stored in sub-directories of 'build_dir' including the full pathname of the script. If the script is location at /full/path/name/macro.C the library will be located at 'build_dir+/full/path/name/macro_C.so' If 'isflat' is true, then no subdirectory is created and the library is created directly in the directory 'build_dir'. Note that in this mode there is a risk than 2 script of the same in different source directory will over-write each other.

void TSystem::SetLinkdefSuffix ( const char *  suffix)
virtual

The 'suffix' will be appended to the name of a script loaded by ACLiC and used to locate any eventual additional linkdef information that ACLiC should used to produce the dictionary.

So by default, when doing .L MyScript.cxx, ACLiC will look for a file name MyScript_linkdef and having one of the .h (.hpp, etc.) extensions. If such a file exist, it will be added to the end of the linkdef file used to created the ACLiC dictionary. This effectively enable the full customization of the creation of the dictionary. It should be noted that the file is intended as a linkdef fragment, so usually you would not list the typical:

#pragma link off ....

Five special variables will be expanded before execution:
Variable name Expands to
