                      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: 
1.3       bertrand   20: 
1.4       bertrand   21:   * RPL/2 requires :
                     22:    - nawk or gawk;
                     23:    - libtool 1.5 or newer. To build RPL/2 on Mac OSX, you should have to
                     24:    add libtool m4 path in tools/file-*/configure.ac and
                     25:    tools/file-*/Makefile.am;
                     26:    - gcc-4.2 or newer;
                     27:    - g++-4.2 or newer;
                     28:    - gfortran-4.2 or newer.
                     29: 
                     30:    RPL/2 build process invoques automake and autoconf.
                     31: 
1.3       bertrand   32:   * OpenSSL issue :
                     33: 
                     34:    OpenSSL does not use any configure script. If build process aborts on
                     35: error related to OpenSSL, you shall try to build OpenSSL before running
                     36: 'make'. On some system, OpenSSL configure script is unable to set compiler
                     37: flags.
                     38: 
1.1       bertrand   39:   * RPL/2 is known to run on :
                     40: 
1.4       bertrand   41:    - Linux (kernel 2.6.26 and above) on i386, amd64, ppc32, sparc32,
1.1       bertrand   42:        sparc64, alpha. Test distribution is Debian. Warning, you have to
                     43:        use NPTL, not LinuxThreads due to a bug in sem_post() that is not
                     44:        async safe.
                     45:    - Solaris 9 and above on i386, amd64, sparc32 (only Solaris 9) and sparc64.
                     46:        It can be built out of the box on Solaris in a 32bits userland. For a
1.2       bertrand   47:        64bits executable, you have to modify some generated makefiles or
                     48:        specify some options. See 64bits on Solaris.
                     49:    - FreeBSD 7.x on i386. I have installed a FreeBSD 7.0, upgraded to 7.2
1.4       bertrand   50:        and RPL/2 ran without any trouble. RPL/2 does not run on FreeBSD 8.0
1.2       bertrand   51:        because sig_into_t struct is not filled. Someone has reported that
                     52:        FreeBSD 7.2 did not filled this struct too...
1.4       bertrand   53:    - NetBSD 4.0 and above with a restriction. NetBSD's sigpending
1.1       bertrand   54:        is broken and it is impossible to use DETACH intrinsic. Bug report
                     55:        has been done and this bug should be fixed in next NetBSD release.
1.2       bertrand   56:        Sigpending has been fixed in NetBSD 5.0 and RPL/2 runs fine.
1.1       bertrand   57: 
                     58:   * RPL/2 should run on :
                     59: 
                     60:    - HP-UX (10.20 and above), but not tested for a long time.
1.4       bertrand   61:    - Linux (2.6.26 and above) on ppc64 and other hardware (arm, hppa...) or
1.1       bertrand   62:        with other distributions than Debian.
1.2       bertrand   63:    - FreeBSD 7.0 and above on other architecture than i386. Please not
                     64:        that I cannot reproduce sig_info_t bug and I do not have more
                     65:        information.
1.1       bertrand   66:    - NetBSD 4.0 and above on other architecture than sparc32 with restriction
                     67:        due to sigpending bug.
                     68:    - Mac OS X.
                     69: 
                     70:    Any information about RPL/2 on these last operating systems are welcome.
                     71: 
                     72:   * RPL/2 is not supported on :
                     73: 
                     74:    - OpenBSD due to a major bug in sigaltstack syscall when a program is
                     75:        linked with -lthread. As this bug comes from OpenBSD libraries,
1.4       bertrand   76:        OpenBSD port has to wait for a fixed sigaltstack. RPL/2 uses pselect()
                     77:        that is unavailable too.
1.2       bertrand   78:    - OpenVMS (work in progress) on Alpha and Integrity due to some bugs in GNV.
                     79:        RPL/2 never works on OpenVMS VAX because GNV is too old on this
                     80:        architecture.
                     81:    - Hurd.
1.1       bertrand   82: 
                     83:   * RPL/2 shall never be supported on :
                     84: 
                     85:    - Cygwin due to some troubles between Cygwin Posix subsystem and Windows.
                     86:        You can try, but I shall never support Cygwin. If someone proposes
                     87:        patches to build RPL/2 on Cygwin, I won't modify official RPL/2 source
                     88:        tree, but only propose these patches against official tarball.
                     89:    - Windows (all versions).
                     90:    - OS/2 and eComStation.
                     91:    - Mac OS preX.
                     92: 
                     93:    Tools directory contains some libraries that are normally provided by
                     94:    all Posix systems. These libraries are built during build process
                     95:    and RPL/2 is statically linked with them because I have seen that on
                     96:    several systems, some Posix libraries have strange 'features'...
                     97: 
                     98:    On all systems, you must install GNU make and you should install
1.4       bertrand   99:    gcc/g++/gfortran (minimal release : 4.2.0). It is possible to build
1.1       bertrand  100:    RPL/2 with some other compilers (for example cc and f95 from SunStudio,
                    101:    or cc and f95 from Digital^WCompaq^WHP) but I do not test all potential
                    102:    combinaisons.
                    103: 
                    104:   * 64 bits on Solaris (are you sure that you need 64bits wide RPL/2 ?)
                    105: 
                    106:    You have to configure RPL/2 with some user defined variables.
                    107: 
                    108:    CFLAGS="$CFLAGS -m64" CXXFLAGS="$CXXFLAGS -m64" FCFLAGS="$FCFLAGS -m64" \
                    109:            FFLAGS="$FFLAGS -m64" LDFLAGS="$LDFLAGS -m64" ./configure (options)
                    110: 
                    111:    If you want to use mysql or postgresql support, you should obtain 64bits
                    112:    binary executables, libraries and daemons. PostgreSQL 8.3.5 does not compile
                    113:    on Solaris 10 in 64bits mode with gcc/GNU ld (due to a strange bug, ld
                    114:    tries to build a 32bits wide library with 64bits objects even if -m64 is
                    115:    specified on command line...). I have not tried mysql.
                    116: 
                    117:    If you want to use rplc, you have to use GNU ld, not Solaris ld, due to
                    118:    another bug that avoid symbol exportation. You have to check that rpl
                    119:    is linked with libmtmalloc and not with libmalloc from libc because there
                    120:    is another bug in Solaris' libc : free() can enter in a deadlock
                    121:    (internal locked mutex).
                    122: 
                    123:    Of course, all 64bits libraries have to be accessible by LD_LIBRARY_PATH.
                    124: 
                    125: tchaikovski:[/usr/shared-apps/bin] > file rpl
                    126: rpl: ELF 64-bit MSB executable SPARCV9 Version 1, dynamically linked,
                    127:      not stripped
                    128: 
                    129:    Very easy^Wnice, isn't it ?
