bfd/configure.host

   1 # This file is a shell script that overrides some of the tools and
   2 # flags used on a host specific basis.
   3
   4 # Since the "bfd/hosts" directory is shared by the bfd, opcodes, and
   5 # binutils directories (at least), the index to it is also shared.
   6 # This is that index.  Each configure.in file should source this file
   7 # in its per-host part.
   8
   9 # This sets the following shell variables:
  10 #  HDEFINES             host specific compiler options
  11 #  host64               set to true if this is a 64 bit host
  12 #  HOST_64BIT_TYPE      host 64 bit type
  13 #  SHLIB_CC             compiler to use when building shared library
  14 #  SHLIB_CFLAGS         flags to use when building shared library
  15 #  PICFLAG              may be set to flag to use to compile PIC
  16 #  SHLINK               may be set to the name to link the shared library to
  17 #  ALLLIBS              may be set to libraries to build
  18 #  HLDFLAGS             LDFLAGS specific to the host
  19 #  RPATH_ENVVAR         environment variable used to find shared libraries
  20 #  INSTALL_SHLIB        install a shared library
