| 4 | # It is advisable to support a few --enable/--disable options to let the |
---|
| 5 | # user select which libraries s/he really wants. |
---|
| 6 | # |
---|
| 7 | # Subdirectories wishing to use multilib should put the following lines |
---|
| 8 | # in the "post-target" section of configure.in. |
---|
| 9 | # |
---|
| 10 | # if [ "${srcdir}" = "." ] ; then |
---|

---|
| 21 | # Things are complicated because 6 separate cases must be handled: |
---|
| 22 | # 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6. |
---|
| 23 | # |
---|
| 24 | # srcdir=. is special. It must handle make programs that don't handle VPATH. |
---|
| 25 | # To implement this, a symlink tree is built for each library and for each |
---|
| 26 | # multilib subdir. |
---|
| 27 | # |
---|
| 28 | # The build tree is layed out as |
---|
| 29 | # |
---|
| 30 | # ./ |
---|
| 31 | # newlib |
---|
| 32 | # m68020/ |
---|
| 33 | # newlib |
---|
| 34 | # m68881/ |
---|
| 35 | # newlib |
---|
| 36 | # |
---|
| 37 | # The nice feature about this arrangement is that inter-library references |
---|
| 38 | # in the build tree work without having to care where you are. Note that |
---|
| 39 | # inter-library references also work in the source tree because symlink trees |
---|
| 40 | # are built when srcdir=. |
---|
| 41 | # |
---|
| 42 | # Unfortunately, trying to access the libraries in the build tree requires |
---|
| 43 | # the user to manually choose which library to use as GCC won't be able to |
---|
| 44 | # find the right one. This is viewed as the lesser of two evils. |
---|
| 45 | # |
---|
| 46 | # Configure variables: |
---|
| 47 | # ${with_target_subdir} = "." for native, or ${target_alias} for cross. |
---|
| 48 | # Set by top level Makefile. |
---|

---|
| 50 | # tree. It exists to handle the case of configuring in the source tree: |
---|
| 51 | # ${srcdir} is not constant. |
---|
| 52 | # ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881). |
---|
| 53 | # |
---|
| 54 | # Makefile variables: |
---|
| 55 | # MULTISRCTOP = number of multilib levels in source tree (+1 if cross) |
---|
| 56 | # (FIXME: note that this is different than ${with_multisrctop}. Check out.). |
---|
