[Olena-patches] [PATCH] Replace exported global variables with static ones.

This allows for separate compilation. * milena/mln/border/thickness.hh, * milena/mln/literal/black.hh, * milena/mln/literal/colors.hh, * milena/mln/literal/grays.hh, * milena/mln/literal/one.hh, * milena/mln/literal/origin.hh, * milena/mln/literal/white.hh, * milena/mln/literal/zero.hh, * milena/mln/tag/init.hh: Here. * milena/mln/trace/entering.hh: Add a missing `inline'. * milena/mln/trace/exiting.hh: Kill trailing whitespaces. Signed-off-by: Benoit Sigoure &lt;tsuna(a)lrde.epita.fr&gt; --- This patch enables me to use separate compilation with my Markov field project. I guess there remains other similar cases in the code though. By the way, I think that Olena has too many small headers. Some headers define only one thing. I would group similar things together to reduce the number of I/O done by the compiler. My project uses only the most basic things in Olena (<mln/core/image2d.hh> <mln/value/rgb8.hh> <mln/border/duplicate.hh> <mln/core/dpoint2d.hh> <mln/io/pgm/save.hh> <mln/io/ppm/load.hh> <mln/level/stretch.hh> <mln/norm/l2.hh>) and each compilation brings in 371 Olena headers, on everage (!). milena/ChangeLog | 16 ++++++++++++++++ milena/mln/border/thickness.hh | 2 +- milena/mln/literal/black.hh | 9 +-------- milena/mln/literal/colors.hh | 14 +++----------- milena/mln/literal/grays.hh | 9 +-------- milena/mln/literal/one.hh | 4 +--- milena/mln/literal/origin.hh | 9 +-------- milena/mln/literal/white.hh | 8 +------- milena/mln/literal/zero.hh | 4 +--- milena/mln/tag/init.hh | 16 +++++++++++----- milena/mln/trace/entering.hh | 3 ++- milena/mln/trace/exiting.hh | 2 +- 12 files changed, 40 insertions(+), 56 deletions(-) diff --git a/milena/ChangeLog b/milena/ChangeLog index 09c6932..f7896cc 100644 --- a/milena/ChangeLog +++ b/milena/ChangeLog @@ -1,3 +1,19 @@ +2007-11-29 Benoit Sigoure &lt;tsuna(a)lrde.epita.fr&gt; + + Replace exported global variables with static ones. + This allows for separate compilation. + * milena/mln/border/thickness.hh, + * milena/mln/literal/black.hh, + * milena/mln/literal/colors.hh, + * milena/mln/literal/grays.hh, + * milena/mln/literal/one.hh, + * milena/mln/literal/origin.hh, + * milena/mln/literal/white.hh, + * milena/mln/literal/zero.hh, + * milena/mln/tag/init.hh: Here. + * milena/mln/trace/entering.hh: Add a missing `inline'. + * milena/mln/trace/exiting.hh: Kill trailing whitespaces. + 2007-11-28 Benoit Sigoure &lt;tsuna(a)lrde.epita.fr&gt; Add the missing inline keywords. diff --git a/milena/mln/border/thickness.hh b/milena/mln/border/thickness.hh index bcb3096..007c0e4 100644 --- a/milena/mln/border/thickness.hh +++ b/milena/mln/border/thickness.hh @@ -41,7 +41,7 @@ namespace mln namespace border { - unsigned thickness = 3; + static unsigned thickness = 3; } // end of namespace mln::border diff --git a/milena/mln/literal/black.hh b/milena/mln/literal/black.hh index b20dbb2..3f0813e 100644 --- a/milena/mln/literal/black.hh +++ b/milena/mln/literal/black.hh @@ -48,14 +48,7 @@ namespace mln /// Literal black. - extern const black_t& black; - - -# ifndef MLN_INCLUDE_ONLY - - const black_t& black = black_t(); - -# endif // !
