From: Ken Raeburn Date: Thu, 21 Apr 2005 21:44:37 +0000 (+0000) Subject: Stop generating per-directory sed scripts, and use perl to compute the patterns X-Git-Tag: ms-bug-test-20060525~281 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ddbc9d85baab7fc1698e215afee7d3970065cfc3;p=krb5.git Stop generating per-directory sed scripts, and use perl to compute the patterns on the fly instead. (Next step, someday, integrate this script and depfix.sed, so we only have to run one script.) * config/post.in (depend-dependencies): Use (and depend on) depfix2.pl instead of .depfix2.sed. (.depfix2.sed): Target deleted. (DEPTARGETS): Delete .depfix2.sed and .depfix2.tmp. * util/depgen.sed: Deleted. * util/depfix2.pl: New file. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@17187 dc483132-0cff-0310-8789-dd5450dbe970 --- diff --git a/src/config/ChangeLog b/src/config/ChangeLog index a5ccc5437..d25c11138 100644 --- a/src/config/ChangeLog +++ b/src/config/ChangeLog @@ -1,3 +1,10 @@ +2005-04-21 Ken Raeburn + + * post.in (depend-dependencies): Use (and depend on) depfix2.pl + instead of .depfix2.sed. + (.depfix2.sed): Target deleted. + (DEPTARGETS): Delete .depfix2.sed and .depfix2.tmp. + 2005-03-25 Ken Raeburn * lib.in (hpux10.exports): New target, constructed similar to diff --git a/src/config/post.in b/src/config/post.in index 573232cb4..32066a1a8 100644 --- a/src/config/post.in +++ b/src/config/post.in @@ -87,19 +87,14 @@ depend-dependencies: .dtmp: $(ALL_DEP_SRCS) $(CC) -M -DDEPEND $(ALL_CFLAGS) $? > .dtmp -# Generate a script for dropping in the appropriate make variables, using -# directory-specific parameters.
