annotate aclocal.m4 @ 1739:c414850f206f

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add support for -boot flag, which allows in-tree execution of Ur/Web The boot flag rewrites most hardcoded paths to point to the build directory, and also forces static compilation. This is convenient for developing Ur/Web, or if you cannot 'sudo make install' Ur/Web. The following changes were made: * Header files were moved to include/urweb instead of include; this lets FFI users point their C_INCLUDE_PATH at this directory at write <urweb/urweb.h>. For internal Ur/Web executables, we simply pass -I$PATH/include/urweb as normal. * Differentiate between LIB and SRCLIB; SRCLIB is Ur and JavaScript source files, while LIB is compiled products from libtool. For in-tree compilation these live in different places. * No longer reference Config for paths; instead use Settings; these settings can be changed dynamically by Compiler.enableBoot () (TODO: add a disableBoot function.) * config.h is now generated directly in include/urweb/config.h, for consistency's sake (especially since it gets installed along with the rest of the headers!) * All of the autotools build products got updated. * The linkStatic field in protocols now only contains the name of the build product, and not the absolute path. Future users have to be careful not to reference the Settings files to early, lest they get an old version (this was the source of two bugs during development of this patch.)

adamc@1141 75 #
adamc@1141 76 # Of course, Automake must honor this variable whenever it calls a
adamc@1141 77 # tool from the auxiliary directory. The problem is that $srcdir (and
adamc@1141 78 # therefore $ac_aux_dir as well) can be either absolute or relative,
adamc@1141 79 # depending on how configure is run. This is pretty annoying, since
adamc@1141 80 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
adamc@1141 81 # source directory, any form will work fine, but in subdirectories a
adamc@1141 82 # relative path needs to be adjusted first.
adamc@1141 83 #
adamc@1141 84 # $ac_aux_dir/missing

adamc@1141 87 # fails if $ac_aux_dir is absolute,
adamc@1141 88 # fails when called from a subdirectory in a VPATH build with
adamc@1141 89 # a relative $ac_aux_dir
adamc@1141 90 #
adamc@1141 91 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
adamc@1141 92 # are both prefixed by $srcdir. In an in-source build this is usually
adamc@1141 93 # harmless because $srcdir is `.', but things will broke when you
adamc@1141 94 # start a VPATH build or use an absolute $srcdir.
adamc@1141 95 #
adamc@1141 96 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
adamc@1141 97 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
adamc@1141 98 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
adamc@1141 99 # and then we would define $MISSING as
adamc@1141 100 # MISSING="\${SHELL} $am_aux_dir/missing"
adamc@1141 101 # This will work as long as MISSING is not called from configure, because
adamc@1141 102 # unfortunately $(top_srcdir) has no meaning in configure.
adamc@1141 103 # However there are other variables, like CC, which are often used in
adamc@1141 104 # configure, and could therefore not use this "fixed" $ac_aux_dir.
adamc@1141 105 #
adamc@1141 106 # Another solution, used here, is to always expand $ac_aux_dir to an
adamc@1141 107 # absolute PATH. The drawback is that using absolute paths prevent a
