[Plplot-devel] pre-processor directives question
Hello, I've moved xwinttf.c to cairo.c and now I want to add some of the other cairo devices (ps, pdf, etc..) to this file. Since some users may have Cairo but not xwindows I'm trying to use preprocessor directives in cairo.c so that they won't get error messages when xwindows does not exist, i.e.: #if defined(PLD_xwinttf) #include #include #include #include #endif However, this fails because apparently PLD_xwinttf is not defined in the context of the compilation of cairo.c. This is puzzling to me since a very similar approach seems to work fine for the gd drivers: #if defined(PLD_png) || defined(PLD_jpeg) || defined(PLD_gif) #include "plplotP.h" #include "drivers.h" ... Any idea what I might be missing? thanks, -Hazen - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML. No limits.

Have you remembered to follow the gd style in cmake/modules/drivers-init.cmake? That means "xwinttf:xwinttf:OFF" must be replaced by "xcairo:cairo:OFF" "pscairo:cairo:OFF" "pdfcairo:cairo:OFF" I am guessing at the names you want for the X, ps and pdf cairo devices so that xcairo would replace your current xwinttf, etc. If you prefer a different naming convention, that is fine, but I do suggest you use the same convention for all cairo-related devices so that xwinttf should be due for a name change regardless, and PLD_xwinttf would be replaced by PLD_xcairo (or whatever) in your code, and you will have to make corresponding changes in config.h.cmake BTW, to confirm the cmake results on the PLD_* variables, you should check config.h in the top of the build tree.

That file showed a mispelled xwinttf which I just fixed so I think everything should work for you now the way you expect. Alan __ Alan W.
