Tru64 patches for Ice V3.0.0 #1

in Patches
The following posts contain patches to be able to build Ice on Tru64 V5.1B using the HP/Compaq C++ V6.5 compiler. I will be posting 1 message per patch with a description of what the patch does and why it was needed.

With the correct compiler flags, Ice already build using the GNU Compiler, however the GNU C++ compiler isn't ABI compatible with the Compaq C++ (default system) compiler, which means it's impossible to link the GNU compiled ICE library with a 3rd party C++ library (e.g. Oracle's OCCI library).

Hopefully these can be incorporated in the standard release, since most are modest corrections.

    Tru64 patches for Ice V3.0.0 #2

    Patch against Make.conf.OSF1

    * use cxx as the default compiler
    * define CC to include a preprocessor define (-D__osf1__), since the icecpp makefile doesn't pass CFLAGS. Fixes:
    make[2]: Entering directory `src/icecpp'
cc -I. -c cccp.c
cc: Error: config.h, line 80: #error "unsupported operating system or platform" (errormessage)
#   error "unsupported operating system or platform"
----^

    * compiler flags suppress certain warning messages. These are:
    cxx: Warning: lex.yy.c, line 1553: statement is unreachable (D:codeunreachable)
                                        if ( ! yy_did_buffer_switch_on_eof )
----------------------------------------^
==
cxx: Warning: PythonUtil.cpp, line 1245: statement either is unreachable or
          causes unreachable code (D:codcauunr)
                _out << "'" << value << "'";
----------------^
==
cxx: Warning: Grammar.tab.c, line 1342: code can never be executed at label
          "yyerrorlab". (D:labelnotreach)
yyerrorlab:
^

    * use -D__USE_STD_IOSTREAM -- from the man page of cxx:
      -D__[NO_]USE_STD_IOSTREAM
       Use or don't use the standard iostreams. If -D__USE_STD_IOSTREAM is
       specified, this forces the inclusion of the ANSI standard version of
       the iostream header file.  This is the default in strict_ansi and
       strict_ansi_errors mode of the compiler. Otherwise the pre-standard
       AT&T-compatible version of iostreams is used.

    * ICEUTIL_OS_LIBS link with -lrt which enables usage of nanosleep()

    Tru64 patches for Ice V3.0.0 #3

    This patch fixes errors like this:
    cxx: Error: /usr/lib/cmplrs/cxx/V6.5-014/include/cxx/algorithm.cc, line 103:
          no operator "!=" matches these operands
            operand types are: DictIndex != const DictIndex
          detected during instantiation of "InputIterator
                    std::find(InputIterator, InputIterator, const T &) [with
                    InputIterator=DictIndex *, T=DictIndex]"
    while (first != last && *first != value)
-----------------------------------^
cxx: Info: 1 error detected in the compilation of "Main.cpp".

    The Standard Template class of the Compaq C++ compiler apparently needs an explicit definition of a != operator, if you use != on the class/struct.

    Interesting note:
    The STL of Compaq C++ is based on the STL from Rogue Wave.

    Rogue Wave has recently released their STL as open source (and has been picked up by the Apache Foundation). I'm not sure if the current release of RW STL (or Apache stdcxx) still requires this.. but might be worth checking out.

    Strangely.. it seems the order of defining the class is important here.

    Tru64 patches for Ice V3.0.0 #5

    Vector initializers need to be of the correct type for the Compaq C++ STL.

    Tru64 patches for Ice V3.0.0 #6

    With default compiler flags, socklen_t isn't known. Normally defining _XOPEN_SOURCE=500 should resolve this, however it seems to cause other errors in include files. Therefor use a typedef for socklen_t like on windows.

    Tru64 patches for Ice V3.0.0 #7

    Aweful patch for an aweful problem. Somehow signal() is defined as a macro in a system header, which by itself shouldn't be a problem, weren't it for a bug in the compiler causing it to replace _condVar->signal() by the macro definition :confused:
    At least, I think this is a bug. Workaround is to undefine the signal() macro.
  • kvogel

    One last remark, for which I didn't make a patch yet. Compiling the code generates warnings for almost every assert() statement:
    cxx: Warning: ConnectionI.cpp, line 920: conversion from pointer to smaller
          integer (D:narrowptr)
            assert(_exception.get());
------------^

    This can be fixed by writing a comparison to NULL, like:

    assert(_exception.get() != NULL);
