    3: ================================================================================
    4: 
    5: --------------------------------------------------------------------------------
    6:     WARNING :
    7: 
    8:     LESSTIF IS BROKEN AND CORRUPTS HEAP. PLEASE, DO NOT USE LESSTIF INSTEAD
    9:     REGULAR MOTIF LIBRARIES!
   10: 
   11:     I SHALL NOT ACCEPT ANY BUG REPORT FROM USERS THAT HAVE BUILD RPL/2 WITH
   12:     LESSTIF LIBRAIRIES SINCE OPENMOTIF IS AVAILABLE.
   13: --------------------------------------------------------------------------------
   14: 
   15:     RPL/2 signifies Reverse Polish Lisp/2. This language is obvious derivated
   16: from the first RPL written by Hewlett-Packard for its 28S calculator. Thus,
   17: this language is a half-compiled high level language which can perform
   18: symbolic and scientific computations.
   19: 
   20:   * RPL/2 is known to run on :
   21: 
   22:     - Linux (kernel 2.6.12 and above) on i386, amd64, ppc32, sparc32,
   23:         sparc64, alpha. Test distribution is Debian. Warning, you have to
   24:         use NPTL, not LinuxThreads due to a bug in sem_post() that is not
   25:         async safe.
   26:     - Solaris 9 and above on i386, amd64, sparc32 (only Solaris 9) and sparc64.
   27:         It can be built out of the box on Solaris in a 32bits userland. For a
   28:         64bits executable, you have to modify some generated makefiles or
   29:         specify some options. See 64bits on Solaris.
   30:     - FreeBSD 7.x on i386. I have installed a FreeBSD 7.0, upgraded to 7.2
   31:          and RPL/2 ran without any trouble. RPL/2 does not run on FreeBSD 8.0
   32:         because sig_into_t struct is not filled. Someone has reported that
   33:         FreeBSD 7.2 did not filled this struct too...
   34:     - NetBSD 4.0 and above on sparc32 with a restriction. NetBSD's sigpending
   35:         is broken and it is impossible to use DETACH intrinsic. Bug report
   36:         has been done and this bug should be fixed in next NetBSD release.
   37:         Sigpending has been fixed in NetBSD 5.0 and RPL/2 runs fine.
   38: 
   39:   * RPL/2 should run on :
   40: 
   41:     - HP-UX (10.20 and above), but not tested for a long time.
   42:     - Linux (2.6.12 and above) on ppc64 and other hardware (arm, hppa...) or
   43:         with other distributions than Debian.
   44:     - FreeBSD 7.0 and above on other architecture than i386. Please not
   45:         that I cannot reproduce sig_info_t bug and I do not have more
   46:         information.
   47:     - NetBSD 4.0 and above on other architecture than sparc32 with restriction
   48:         due to sigpending bug.
   49:     - Mac OS X.
   50: 
   51:     Any information about RPL/2 on these last operating systems are welcome.
   52: 
   53:   * RPL/2 is not supported on :
   54: 
   55:     - OpenBSD due to a major bug in sigaltstack syscall when a program is
   56:         linked with -lthread. As this bug comes from OpenBSD libraries,
   57:         OpenBSD port has to wait for a fixed sigaltstack.
   58:     - OpenVMS (work in progress) on Alpha and Integrity due to some bugs in GNV.
   59:         RPL/2 never works on OpenVMS VAX because GNV is too old on this
   60:         architecture.
   61:     - Hurd.
   62: 
   63:   * RPL/2 shall never be supported on :
   64: 
   65:     - Cygwin due to some troubles between Cygwin Posix subsystem and Windows.
   66:         You can try, but I shall never support Cygwin. If someone proposes
   67:         patches to build RPL/2 on Cygwin, I won't modify official RPL/2 source
   68:         tree, but only propose these patches against official tarball.
   69:     - Windows (all versions).
   70:     - OS/2 and eComStation.
   71:     - Mac OS preX.
   72: 
   73:     Tools directory contains some libraries that are normally provided by
   74:     all Posix systems. These libraries are built during build process
   75:     and RPL/2 is statically linked with them because I have seen that on
   76:     several systems, some Posix libraries have strange 'features'...
   77: 
   78:     On all systems, you must install GNU make and you should install
   79:     gcc/g++/gfortran (minimal release : 4.0.0). It is possible to build
   80:     RPL/2 with some other compilers (for example cc and f95 from SunStudio,
   81:     or cc and f95 from Digital^WCompaq^WHP) but I do not test all potential
   82:     combinaisons.
   83: 
   84:   * 64 bits on Solaris (are you sure that you need 64bits wide RPL/2 ?)
   85: 
   86:     You have to configure RPL/2 with some user defined variables.
   87: 
   88:     CFLAGS="$CFLAGS -m64" CXXFLAGS="$CXXFLAGS -m64" FCFLAGS="$FCFLAGS -m64" \
   89:             FFLAGS="$FFLAGS -m64" LDFLAGS="$LDFLAGS -m64" ./configure (options)
   90: 
   91:     If you want to use mysql or postgresql support, you should obtain 64bits
   92:     binary executables, libraries and daemons. PostgreSQL 8.3.5 does not compile
   93:     on Solaris 10 in 64bits mode with gcc/GNU ld (due to a strange bug, ld
   94:     tries to build a 32bits wide library with 64bits objects even if -m64 is
   95:     specified on command line...). I have not tried mysql.
   96: 
   97:     If you want to use rplc, you have to use GNU ld, not Solaris ld, due to
   98:     another bug that avoid symbol exportation. You have to check that rpl
   99:     is linked with libmtmalloc and not with libmalloc from libc because there
  100:     is another bug in Solaris' libc : free() can enter in a deadlock
  101:     (internal locked mutex).
  102: 
  103:     Of course, all 64bits libraries have to be accessible by LD_LIBRARY_PATH.

  105: tchaikovski:[/usr/shared-apps/bin] > file rpl
  106: rpl: ELF 64-bit MSB executable SPARCV9 Version 1, dynamically linked,
  107:      not stripped
  108: 
  109:     Very easy^Wnice, isn't it ?
