    2:     RPL/2 (R)
    3: ================================================================================

    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:     DO NOT USE 'make install-strip' THAT BREAKS RPL/2.
   15: --------------------------------------------------------------------------------
   16: 
   17:     RPL/2 signifies Reverse Polish Lisp/2. This language is obvious derivated
   18: from the first RPL written by Hewlett-Packard for its 28S calculator. Thus,
   19: this language is a half-compiled high level language which can perform
   20: symbolic and scientific computations.
   21: 
   22: 
   23:   * RPL/2 requires :
   24:     - nawk or gawk;
   25:     - libtool 1.5 or newer. To build RPL/2 on Mac OSX, you should have to
   26:     add libtool m4 path in tools/file-*/configure.ac and
   27:     tools/file-*/Makefile.am;
   28:     - gcc-4.4 or newer;
   29:     - g++-4.4 or newer;
   30:     - gfortran-4.4 or newer.
   31: 
   32:     RPL/2 build process invoques automake and autoconf.
   33: 
   34:   * OpenSSL issue :
   35: 
   36:     OpenSSL does not use any configure script. If build process aborts on
   37: error related to OpenSSL, you shall try to build OpenSSL before running
   38: 'make'. On some system, OpenSSL configure script is unable to set compiler
   39: flags.
   40: 
   41:   * RPL/2 is known to run on :
   42: 
   43:     - Linux (kernel 2.6.26 and beyond). Test distribution is Debian.
   44:     - Solaris 8 and beyond.
   45:         It can be built out of the box on Solaris in a 32bits userland. For a
   46:         64bits executable, you have to modify some generated makefiles or
   47:         specify some options. See 64bits on Solaris.
   48:     - FreeBSD 7.x. I have installed a FreeBSD 7.0, upgraded to 7.2
   49:         and RPL/2 ran without any trouble. RPL/2 does not run on early
   50:         FreeBSD 8.0 because sig_info_t struct is not filled. This bug is now
   51:         fixed. Someone has reported that FreeBSD 7.2 did not filled this
   52:         struct too...
   53:     - NetBSD 5.0 and beyond.
   54:     - OpenBSD 4.8 and beyond.
   55:     - Windows with Cygwin (>= 1.7.5).
   56:     - OS/2 and eComStation with EMX (>= 0.9d). You probably have to
   57:         recreate configure script and makefiles with aclocal, autoconf and
   58:         automake.
   59:     - Mac OS X.
   60: 
   61:   * RPL/2 should run on :
   62: 
   63:     - AIX
   64:     - HP-UX (10.20 and beyond), but not tested for a long time.
   65:     - NetBSD 4.0 and beyond with restriction due to sigpending bug.
   66: 
   67:     Any information about RPL/2 on these last operating systems are welcome.
   68: 
   69:   * RPL/2 is not supported on :
   70: 
   71:     - OpenVMS (work in progress) on Alpha and Integrity due to some bugs in GNV.
   72:         RPL/2 never works on OpenVMS VAX because GNV is too old on this
   73:         architecture.
   74:     - Hurd because sig_info_t is not filled.
   75: 
   76:   * RPL/2 shall never be supported on :
   77: 
   78:     - Windows (all versions) without Cygwin.
   79:     - Mac OS preX.
   80: 
   81:     Tools directory contains some libraries that are normally provided by
   82:     all Posix systems. These libraries are built during build process
   83:     and RPL/2 is statically linked with them because I have seen that on
   84:     several systems, some Posix libraries have strange 'features'...
   85: 
   86:     On all systems, you must install GNU make and you should install
   87:     gcc/g++/gfortran (minimal release : 4.2.0). It is possible to build
   88:     RPL/2 with some other compilers (for example cc and f95 from SunStudio,
   89:     or cc and f95 from Digital^WCompaq^WHP) but I do not test all potential
   90:     combinaisons.
   91: 
   92:   * 64 bits on Solaris (are you sure that you need 64bits wide RPL/2 ?)
   93: 
   94:     You have to configure RPL/2 with some user defined variables.
   95: 
   96:     CFLAGS="$CFLAGS -m64" CXXFLAGS="$CXXFLAGS -m64" FCFLAGS="$FCFLAGS -m64" \
   97:             FFLAGS="$FFLAGS -m64" LDFLAGS="$LDFLAGS -m64" ./configure (options)
   98: 
   99:     If you want to use mysql or postgresql support, you should obtain 64bits
  100:     binary executables, libraries and daemons. PostgreSQL 8.3.5 does not compile
  101:     on Solaris 10 in 64bits mode with gcc/GNU ld (due to a strange bug, ld
  102:     tries to build a 32bits wide library with 64bits objects even if -m64 is
  103:     specified on command line...). I have not tried mysql.
  104: 
  105:     If you want to use rplc, you have to use GNU ld, not Solaris ld, due to
  106:     another bug that avoid symbol exportation. You have to check that rpl
  107:     is linked with libmtmalloc and not with libmalloc from libc because there
  108:     is another bug in Solaris' libc : free() can enter in a deadlock
  109:     (internal locked mutex).
  110: 
  111:     Of course, all 64bits libraries have to be accessible by LD_LIBRARY_PATH.
  112: 
  113: tchaikovski:[/usr/shared-apps/bin] > file rpl
  114: rpl: ELF 64-bit MSB executable SPARCV9 Version 1, dynamically linked,
  115:      not stripped
  116: 
  117:     Very easy^Wnice, isn't it ?
