Hi!
I wanted to compile next example: x01c.c where are the possibilities to work
with FOUR subplots.
What I received:
x01c.c: In function ‘plot2’:
x01c.c:323:5: warning: implicit declaration of function ‘plwid’
[-Wimplicit-function-declaration]
plwid( 2 );
^~~~~
./x01c.o: In function `plot2':
x01c.c:(.text+0x5b6): undefined reference to `plwid'
x01c.c:(.text+0x5da): undefined reference to `plwid'
collect2: error: ld returned 1 exit status
After comments these unknown functions plwid in example x01c.c it was compiled
successfully.
// Draw the line
plcol0( 3 );
//plwid( 2 );
plline( 100, x, y );
//plwid( 1 );
I think it is not important to work with plwid( 2 ) or without it.
If yes, I will continue to work with x01c.c without plwid(...).
Hi Sergey:
The plwid function has long been deprecated. During that time our
examples have been consistent (they use plwidth rather than plwid). So
somehow I believe you are attempting to compile really old examples
with a new PLplot version, and that is not possible for such
backwards-incompatible changes.
To avoid such backwards-incompatibility issues, I suggest you use the
latest PLplot version (currently 5.13.0, but the release of 5.14.0
should be happening fairly soon this year) including the compatible
set of examples that are distributed with that version.
Note, also that for our forthcoming release (5.14.0) plwid will be
changed from a deprecated status (only available if you use the
-DPL_DEPRECATED=ON option to cmake) to completely removed status
because it has been deprecated for such a long time.
