The version of Automake in RHL 7.3 is rather old. Could you please try with a newer version? If you can reproduce with recent/current automake, then could you please attach some example tarball to help test this problem? Anyway I suggest taking this issue upstream to one of the automake lists if it is still present in Automake 1.8. Is it possible you could provide a small testcase for this, please? That would make it easier to look into? If this is still an issue with the latest automake, please resubmit your bug report to <bug-automake>. Thanks. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003 Description of problem: Suppose that, for some reason, I get into a state where my foo.h file is older than my foo.y file, but my foo.c file is up-to-date. This happened to me when I had a piece of software stored in a version control system, and the original authors had placed foo.c, foo.h, and foo.y all into the version control system. So when I did make, the following rule fired foo.h: foo.c @if test ! -f $@; then \ rm -f foo.c; \ $(MAKE) foo.c; \ else :; fi Since foo.h was older than foo.c, the rule fired. But since foo.h existed, nothing happened. I am not sure the best way to fix this. One approach might be to fix it for bison. Thus if yacc=bison then generate %.c %.h: %.y bison $< and get rid of all the nonsense about ylwrap. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Take a yacc file, foo.y 2. make foo.c 3. touch foo.y 4. touch foo.c 5. make Actual Results: On step 5, nothing is remade, even though foo.h is older than foo.y Expected Results: foo.h should have been rebuilt.
