http://hg.python.org/cpython/rev/435eec7b41f0 changeset: 70552:435eec7b41f0 user: Ralf Schmitt <ralf@systemexit.de> date: Tue May 31 17:10:03 2011 -0500 summary: disable ASDLGEN if hg won't work, or if python is not installed. This change makes configure check for - the existence of a hg repository - the hg executable itself - the python executable Running $(srcdir)/Parser/asdl_c.py (i.e. ASDLGEN) will fail if any of the above prerequisites is missing, so we now disable it instead. closes #12225 files: Makefile.pre.in | 2 +- configure.in | 15 +++++++++++++++ 2 files changed, 16 insertions(+), 1 deletions(-) diff --git a/Makefile.pre.in b/Makefile.pre.in --- a/Makefile.pre.in +++ b/Makefile.pre.in @@ -274,7 +274,7 @@ ASDLGEN_FILES= $(srcdir)/Parser/asdl.py $(srcdir)/Parser/asdl_c.py # XXX Note that a build now requires Python exist before the build starts -ASDLGEN= $(srcdir)/Parser/asdl_c.py +ASDLGEN= @DISABLE_ASDLGEN@ $(srcdir)/Parser/asdl_c.py ########################################################################## # Python diff --git a/configure.in b/configure.in --- a/configure.in +++ b/configure.in @@ -811,7 +811,13 @@ AC_SUBST(HGVERSION) AC_SUBST(HGTAG) AC_SUBST(HGBRANCH) + +if test -e $srcdir/.hg/00changelog.i +then AC_CHECK_PROG(HAS_HG, hg, found, not-found) +else +HAS_HG=no-repository +fi if test $HAS_HG = found then HGVERSION="hg id -i \$(srcdir)" @@ -823,6 +829,15 @@ HGBRANCH="" fi +AC_SUBST(DISABLE_ASDLGEN) +DISABLE_ASDLGEN="" +AC_CHECK_PROG(HAS_PYTHON, python, found, not-found) +if test $HAS_HG != found -o $HAS_PYTHON != found +then + DISABLE_ASDLGEN="@echo hg: $HAS_HG, python: $HAS_PYTHON! cannot run \$(srcdir)/Parser/asdl_c.py #" +fi + + case $MACHDEP in bsdos*|hp*|HP*) # install -d does not work on BSDI or HP-UX -- Repository URL: http://hg.python.org/cpython
