Re: [PATCH] use new global, Version, rather than macro, VERSION

Before, due to the use of VERSION, the old .o files would be useless and just pollute the cache. This first patch uses version-controlled files named src/version.[ch]. The second change-set makes it so they are generated, and hence not version-controlled. Comments or suggested improvements welcome. This is EXACTLY the heart of the matter impacting the GNUmakefile discussion. In your second patch, why is version.h generated? In reality, only version.c needs to be generated, since it is the only file with varying contents. I did that to keep the declaration and definition close. It's not essential, but feels a little cleaner. * src/Makefile.am: Put it in a library that everyone links to. (noinst_LIBRARIES, libver_a_SOURCES): Define. (LDADD): Add libver.a. Is the library a necessity, or is version.o sufficient? Using version.o would be sufficient, but would require unmaintainable changes to coreutils' src/Makefile.am. Using a library seems like the easiest way to ensure each binary gets the new symbol without enumerating the dependency manually in src/Makefile.am. If someone can find a way to avoid the library with that constraint, I'd much prefer that. +BUILT_SOURCES += version.c +version.c: Makefile +rm -f $@ +printf '#include config.h\n' [EMAIL PROTECTED] +printf 'char const *Version = $(PACKAGE_VERSION);\n' [EMAIL PROTECTED] +@chmod a-w [EMAIL PROTECTED] +mv [EMAIL PROTECTED] $@ Oops. This still doesn't solve the GNUmakefile debate. For this design to solve that issue, you need to use something other than PACKAGE_VERSION, so that you can guarantee that config.h is not polluted with version changes. Is it worth calling git-version-gen directly? For now, my aim was solely to avoid ccache waste. And as long as the compiled code doesn't *use* the changing symbols that's just fine. Of course, it'd be even better if config.h didn't have to change at all, but to get there, we'll have to change or override m4 macros that emit *VERSION definitions. One step at a time ;-) ___ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
French accents
Hello, I am having difficulty with file names that have French accents. For example the file.- AfficheJourn\351e\311tudeP\350reaveclogos-1.pdf exists but because it has the French e accent in its title the programme is not recognizing it. What to do?

Using a library seems like the easiest way to ensure each binary gets the new symbol without enumerating the dependency manually in src/Makefile.am. Good point. So other projects, with fewer programs, can skip the convenience library aspect of your solution. For now, my aim was solely to avoid ccache waste.

One step at a time ;-) Your patch meets the stated goal, so I think it's fine to check in. If nothing else, it made me investigate using ccache on my machine. - -- Don't work too hard, make some time for fun as well!
