This is GNAT version 3.01 compiled as ELF binaries under linux.  If
your system is not ELF, this is not for you.  It was compiled with gcc
2.7.2, binutils 2.6.0.2, and libc-5.2.16. You definately need at least
libc-5.2.16 to use this release.  It is publically available, so you
should have no problems getting a copy.  The gcc 2.7.2 binary is not
included in this release (except for the GNAT specific part) but is
required to use GNAT. You must get the gcc-2.7.2 binaries from somewhere
like sunsite.unc.edu or tsx-11.mit.edu.  Note that everything included was
compiled from publically available packages.  This means that anyone can
recompile GNAT 3.01 for themselves, but I strongly discourage it since
there are some problems that are still being addressed (see 3&5 below).

There are a few items that need to be mentioned:

  1) The pthread library is 1.60 beta 2, but it is the
     version that has been incorporated into the libc library.
     It is not included in the binary release of libc-5.2.16, but
     you can compile it from the sources if you want.  I have included
     it in the GNAT binary archive.

  2) The release includes usr/bin/gcc.  This is because important
     information required by gcc to recognize other languages has been
     removed from the base source code and is instead compiled in
     separately.

  3) These are the steps required to compile GNAT:

      # first, setup the gcc source as instructed by the GNAT README,
      # apply the gcc-272.dif to gcc-2.7.2 and apply the linux.dif from
      # the linux binary archive to the GNAT source.
      # mv the gnat-3.01-src/src/ada directory into the gcc-2.7.2 directory.
      # cd to the gcc-2.7.2 directory.
      ./configure --target=i486-linux --with-gnu-as --with-gnu-ld --prefix=/usr
      make CFLAGS="-O3 -fomit-frame-pointer"
      make CFLAGS="-O3 -fomit-frame-pointer" gnattools
      make CFLAGS="-g -fPIC -D_MIT_POSIX_THREADS" gnatlib
      su
      make install

     Some tweaking is necessary to make a shared library and the steps are
     not well-defined at this time, so I am not going to get into it.

  4) This release includes a shared library version of libgnat.  I have
     placed it in /usr/lib so that you do not need to add another entry
     in /etc/ld.so.conf.

  5) I have been requested to omit a patch to gcc that is required to get
     around a problem I encountered when compiling the RTS.  My patch does
     not fix the true bug in GNAT, but sorta covers it up.  A proper solution
     is being investigated by the folks at ACT.  If you have a serious need
     to compile GNAT yourself, think twice :-), then if you still need to
     do it, I can provide you with my patch.

  6) All example programs compile and run with the exception of diners.
     The problem has already been reported and is on ACT's list.  I have
     also minimally tested tasking and it appears to work.

  Please report any and all ommisions or oversights on my part in the
contents of this binary release.

Enjoy,
