# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets |
|
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to |
|
# '$srcdir', '$srcdir/..', or '$srcdir/../..'. |
|
# |
|
# Of course, Automake must honor this variable whenever it calls a |
|
# tool from the auxiliary directory. The problem is that $srcdir (and |
|
# therefore $ac_aux_dir as well) can be either absolute or relative, |
|
# depending on how configure is run. This is pretty annoying, since |
|
# it makes $ac_aux_dir quite unusable in subdirectories: in the top |
|
# source directory, any form will work fine, but in subdirectories a |
|
# relative path needs to be adjusted first. |
|
# |
|
# $ac_aux_dir/missing |
|
# fails when called from a subdirectory if $ac_aux_dir is relative |
|
# $top_srcdir/$ac_aux_dir/missing |
|
# fails if $ac_aux_dir is absolute, |
|
# fails when called from a subdirectory in a VPATH build with |
|
# a relative $ac_aux_dir |
|
# |
|
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
|
# are both prefixed by $srcdir. In an in-source build this is usually |
|
# harmless because $srcdir is '.', but things will broke when you |
|
# start a VPATH build or use an absolute $srcdir. |
|
# |
|
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
|
# iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
|
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
|
# and then we would define $MISSING as |
|
# MISSING="\${SHELL} $am_aux_dir/missing" |
|
# This will work as long as MISSING is not called from configure, because |
|
# unfortunately $(top_srcdir) has no meaning in configure. |
|
# However there are other variables, like CC, which are often used in |
|
# configure, and could therefore not use this "fixed" $ac_aux_dir. |
|
# |
|
# Another solution, used here, is to always expand $ac_aux_dir to an |
|
# absolute PATH. The drawback is that using absolute paths prevent a |
|
# configured tree to be moved without reconfiguration. |

# AM_PROG_INSTALL_STRIP |
|
# --------------------- |
|
# One issue with vendor 'install' (even GNU) is that you can't |
|
# specify the program used to strip binaries. This is especially |
|
# annoying in cross-compiling environments, where the build's strip |
|
# is unlikely to handle the host's binaries. |
|
# Fortunately install-sh will honor a STRIPPROG variable, so we |
|
# always use install-sh in "make install-strip", and initialize |
|
# STRIPPROG with the value of the STRIP variable (set by the user). |
|

# Installed binaries are usually stripped using 'strip' when the user |
|
# run "make install-strip". However 'strip' might not be the right |

# tool to use in cross-compilation environments, therefore Automake |

# will honor the 'STRIP' environment variable to overrule this program. |
