| 491 | 1. Supported and Tested Platforms
|
|---|
| 492 | ---------------------------------
|
|---|
| 493 |
|
|---|
| 494 | o SUN Solaris 5.7, C++ 5.2 Patch 109508-03.
|
|---|
| 495 | o Linux, gcc 2.95.2, egcs-2.91.66 (egcs 1.1.2).
|
|---|
| 496 | This configuration was tested with the RedHat 6.1 distribution, but
|
|---|
| 497 | versions of Geant4 have also been compiled successfully on more recent
|
|---|
| 498 | RedHat, Debian and Suse distributions.
|
|---|
| 499 | o NT 4.0 (Service Pack 4) or Windows-2000 and Cygnus Tools b20 with:
|
|---|
| 500 | Visual C++ 6.0 Service Pack 5
|
|---|
| 501 |
|
|---|
| 502 | Platforms also tested but giving rise to some problems - see below:
|
|---|
| 503 |
|
|---|
| 504 | o DEC V4.0, cxx C++ V6.1-027.
|
|---|
| 505 |
|
|---|
| 506 | Platforms configured but not tested and not supported:
|
|---|
| 507 | o HP 10.20, aCC C++ B3910B A.01.23
|
|---|
| 508 | o SGI V6.5.5, CC 7.2.1 with ObjectSpace
|

|
|---|
| 510 |
|
|---|
| 511 |
|
|---|
| 512 | 2. ANAPHE and CLHEP
|
|---|
| 513 | -------------------
|
|---|
| 514 |
|
|---|
| 515 | Geant4 4.0 requires the installation of CLHEP.
|
|---|
| 516 |
|
|---|
| 517 | See CLHEP (http://cern.ch/clhep/INSTALLATION/clhep.html).
|
|---|
| 518 | Tests have been performed with CLHEP 1.7.0.0.
|
|---|
| 519 |
|
|---|
| 520 | By default, the CLHEP installation scripts will activate ISO/ANSI C++ features
|
|---|
| 521 | if the compiler is capable. You need to explicitly disable CLHEP settings in
|
|---|
| 522 | case you wish non-ISO/ANSI setup on specific compilers.
|
|---|
| 523 |
|
|---|
| 524 | Geant4 4.0 coworks with ANAPHE 3.6.5 and components included therein:
|
|---|
| 525 | Objectivity 6.1.3
|
|---|
| 526 | HepODBMS 0.3.3.1
|
|---|
| 527 | CLHEP 1.7.0.0
|
|---|
| 528 |
|
|---|
| 529 | For more information about ANAPHE, see: http://cern.ch/anaphe
|
|---|
| 530 |
|
|---|
| 531 |
|
|---|
| 532 | 3. The Standard Template Library
|
|---|
| 533 | --------------------------------
|
|---|
| 534 |
|
|---|
| 535 | Native versions of STL have been tested on the following platforms:
|
|---|
| 536 |
|
|---|
| 537 | Windows/2000, Linux, DEC and SUN.
|
|---|
| 538 |
|
|---|
| 539 | NOTES:
|
|---|
| 540 |
|
|---|
| 541 | - Platform specific setup:
|
|---|
| 542 | o DEC: Native STL is required for ISO/ANSI setup.
|
|---|
| 543 | o SUN: Native STL is required for ISO/ANSI setup (CC 5.2 only).
|
|---|
| 544 | o Linux: Native STL is required (non ISO/ANSI setup for egcs compiler only).
|
|---|
| 545 | o W2000: Native STL and ISO/ANSI setup required (VC++ 6.0).
|
|---|
| 546 |
|
|---|
| 547 |
|
|---|
| 548 | 4. Persistency
|
|---|
| 549 | --------------
|
|---|
| 550 |
|
|---|
| 551 | Platform
|
|---|
| 552 | --------
|
|---|
| 553 |
|
|---|
| 554 | Persistency in Geant4 4.0 release is tested on the following
|
|---|
| 555 | platforms:
|
|---|
| 556 |
|
|---|
| 557 | G4SYSTEM OS C++ compiler HepODBMS Objectivity
|
|---|
| 558 | --------- ----------- ------------ --------- -----------
|
|---|
| 559 | SUN-CC SunOS 5.7 CC 5.2 0.3.3.1 6.1.3 (*)
|
|---|
| 560 | Linux-g++ RedHat 6.1 gcc-2.95.2 0.3.3.1 6.1.3 (#)
|
|---|
| 561 |
|
|---|
| 562 | (*) HepODBMS header files must be prepared with "ooddlx -noline"
|
|---|
| 563 | option. See below.
|
|---|
| 564 | (#) See g4odbms_setup[.sh.csh] in example PersistentEx01 in
|
|---|
| 565 | 'geant4/examples/extended/persistency' for example setup scripts.
|
|---|
| 566 |
|
|---|
| 567 | Known Problems
|
|---|
| 568 | --------------
|
|---|
| 569 |
|
|---|
| 570 | - There are several warning messages on some platforms during the
|
|---|
| 571 | installation of the libraries and the compilation of the examples.
|
|---|
| 572 | Most of them can be safely ignored. It is annoying but hard to get
|
|---|
| 573 | rid of them due to various reasons.
|
|---|
| 574 |
|
|---|
| 575 | - If you are using Solaris7 CC compiler 5.2 (SUN-CC) with the original
|
|---|
| 576 | release version, persistent header files has to be generated by
|
|---|
| 577 | ooddlx with "-noline" option due to a bug in C++ compiler.
|
|---|
| 578 | This workaround applies not only to Geant4 Persistency category but
|
|---|
| 579 | also to HepODBMS, and the user defined ddl files as well.
|
|---|
| 580 | This is the default for SUN-CC configuration for Geant4 GNUmakefiles.
|
|---|
| 581 | When this option is turned on, it removes the "#line" directive of
|
|---|
| 582 | the file name and the line number of the original .ddl file. As a
|
|---|
| 583 | consequences, C++ compiler no longer "tells" the correct file name
|
|---|
| 584 | and the line number of the .ddl file if compiler error occurs. When
|
|---|
| 585 | you design a persistent object with Geant4 GNUmakefiles and get the
|
|---|
| 586 | compiler errors, try to identify the problem by first looking into
|
|---|
| 587 | the header file generated by ooddlx, and then locate the source of
|
|---|
| 588 | the problem by looking into the .ddl file.
|
|---|
| 589 | A patch to the compiler is released from SUN, and you may remove this
|
|---|
| 590 | option by commenting out the line:
|
|---|
| 591 |
|
|---|
| 592 | G4DDLX_FLAGS += -noline
|
|---|
| 593 |
|
|---|
| 594 | in the file $G4INSTALL/config/sys/SUN-CC.gmk.
|
|---|
| 595 |
|
|---|
| 596 | You can check the SUN-CC patch by the following command:
|
|---|
| 597 |
|
|---|
| 598 | % what `which CC` | grep RELEASE
|
|---|
| 599 |
|
|---|
| 600 |
|
|---|
| 601 | 5. Compiler Specific Problems
|
|---|
| 602 | -----------------------------
|
|---|
| 603 |
|
|---|
| 604 | o DEC V4.0, cxx C++ V6.1-027.
|
|---|
| 605 |
|
|---|
| 606 | - We have found cases of mis-compilation of min and max templates
|
|---|
| 607 | on DEC. We have traced those which cause serious malfunction
|
|---|
| 608 | but there is no guarantee that there are no other cases.
|
|---|
| 609 | Detailed inspection of assembler output suggests that this
|
|---|
| 610 | problem might not be confined to min and max. This has been
|
|---|
| 611 | reported to DEC/Compaq. We understand a new version 6.2 of the
|
|---|
| 612 | compiler is now available. However we cannot guarantee correct
|
|---|
| 613 | execution of Geant4 on DEC with the current version of the
|
|---|
| 614 | compiler.
|
|---|
| 615 | - A bug in cin.getline() system function causes an anomalous
|
|---|
| 616 | behavior when running in interactive-mode on DEC-cxx 6.1 in
|
|---|
| 617 | ISO/ANSI mode. We tested the bug has been fixed in more recent
|
|---|
| 618 | versions of the compiler.
|
|---|
| 619 |
|
|---|
| 620 |
|
|---|
| 621 | 6. Known Run-Time Problems and Limitations
|
|---|
| 622 | ------------------------------------------
|
|---|
| 623 |
|
|---|
| 624 | For a complete list of outstanding run-time problems and to submit any
|
|---|
| 625 | problem you may find running this version of Geant4, please refer to the
|
|---|
| 626 | Geant4 Problem Reporting System, available on the Web at this address:

|
|---|
| 629 |
|
|---|
| 630 |
|
|---|
| 631 | 7. Compilation Warnings
|
|---|
| 632 | -----------------------
|
|---|
| 633 |
|
|---|
| 634 | There are compilation warnings on some platforms. We do not believe
|
|---|
| 635 | that any will lead to incorrect run-time behaviour, but we are working
|
|---|
| 636 | on reducing them.
|
|---|
| 637 |
|
|---|
| 638 |
|
|---|
| 639 | 8. Known Run-Time Warnings
|
|---|
| 640 | --------------------------
|
|---|
| 641 |
|
|---|
| 642 | The following messages can be written to error output while tracking. We
|
|---|
| 643 | believe none give rise to incorrect behaviour.
|
|---|
| 644 |
|
|---|
| 645 | o G4PropagateInField: Warning: Particle is looping
|
|---|
| 646 | - tracking in field will be stopped.
|
|---|
| 647 | It has performed 10000 steps in Field while a maximum of 10000
|
|---|
| 648 | are allowed.
