Re: [Plplot-devel] PLplot + Windows + Octave
I've come a bit further with my Octave/Windows/PLplot problem.
For test purposes I replaced the fork in matwrap with a simple open.
(As far as I understand the fork is supposed to prevent problems with
quotes, which I don't have in my calls.) This worked fine, but I'm
running into new difficulties:
The matwrap script now dies like this:
unrecognized type 'FI'
plplot_octave.h:0: fatal error: when writing output to : Invalid argument
compilation terminated.
Through extensive debug output I traced this problem to the parse_str
function, which seems unable to interpret MinGW's stdio.h / stdlib.h and
possibly others as well.
The garbled call comes in the section # Look for variable definitions:
around line ~480, where a regexp replacement seems to fail. The
following call to canonicalize_type consequently fails.
When in stdio.h, the regular expression tries to match to, for example $_=
typedef struct _iobuf
0 FILE;
extern ;
FILE* ;
FILE* ;
int ;
int ;
int ;
int ;
FILE* ;
char* ;
...
and comes up with $1=[](\06, i guess), $2=FI and $3=LE.
The catch is probably the typedef ...{...} FILE; , since there is no
variable name following.
Ideas, anyone? It is annoying that the build fails on a
collector/preparation script. ;-)

Hi all,
I've sent this question as a Support Request on SFnet and was referred
to this mailing list (not without some good initial help, thanks smekal).
The case is this:
I'm trying to get PLplot to work together with Octave on a (urks)
Windows machine. PLplot compiles (and runs) fine for GCC but as soon as
I enable the Octave binding, I get this:
mingw32-make
[..]
[ 43%] Generating plplot_octave.cc, tmp_stub
'-' is not recognized as an internal or external command,
operable program or batch file.
matwrap: C preprocessor exited with error status
mingw32-make[2]: *** [bindings/octave/plplot_octave.cc] Error 2
mingw32-make[1]: *** [bindings/octave/CMakeFiles/plplot_octave.dir/all]
Error 2
mingw32-make: *** [all] Error 2
The is not recognized expression is a Windows command line error
message when it tries to open/run something that does not exist.
I have traced the error to the perl script matwrap, line ~211
(plus/minus) where it seems that the program wants to try and fork -
which, in Windows, leads to problems. What can I do?
Greetings from Oslo,

Re: [Plplot-devel] Ada examples now all give just a red rectangle with no plot
As a second report, I can confirm that I also see this. Using -cmap0 on the command line to set the default palette cures the problem, so it looks like it is somewhere in the initialisation. This just seems to be an Ada issue, and happens for all the drivers I've tried. This is odd since with the thin bindings Ada should just be making the same plplot calls as all the other languages.

Re: [Plplot-devel] D bindings (nearly finished) and tests on Mac OS X
Hi Andrew,
I looked at the source code for the bindings and I realised that
currently we do not use tcl_precision or something similar to _return_
values from PLplot routines. Instead we simply use %f to format the
returned number. Up to now that was satisfactory, but the time functions
return data with high precision.
As a temporary workaround, could you try with a format like %.20f -
like:
Line 283, 284 in pltclgen.tcl:
PLFLT {
puts $GENFILE sprintf( buf, \%.20f\, $argname($i) );
(I seem to have added all manner of comments about it - never got around
to actually implement them. It was not pressing then. I will be glad
to take care of it myself, once I can comfortably access my computer
at home again)
Regards,
Arjen

Are there any ways round this? I tried setting tcl_precision, but it made no

Although I don't recognize anything relevant in Alban's patch that Andrew committed, it appears that some change he did solved all the superscript/subscript issues that appeared before. The same example works OK for -dev psc and -dev psttfc and works (with regard to font size issues and vertical offsets, but not horizontal offsets which generally have issues for this device in any case) for -dev wxwidgets (wxGC).

Re: [Plplot-devel] Ada examples now all give just a red rectangle with no plot
I now am seeing red also, at version 10314. Comparing SVG files for C and Ada on Example 1: The file sizes are the same; There are 535 differences; Every difference (date excepted) is due to either stroke=#FF or fill=#FF in the Ada-generated file. That's a lot of red. The same experiment on PostScript files: File sizes same 13 differences Every difference is exactly due to 1. 0. 0. C in the Ada-generated file where in the C-generated file there was x y z C where x, y, z are floats of various values. I'm going to take a wild guess that r g b C sets the color in PostScript. Using the -cmap0 option, these files work correctly cmap0_black_on_white.pal cmap0_default.pal cmap0_white_bg.pal whereas this one makes red cmap0_alternate.pal Disassembling the red SVG file for Ada example 1 with a graphics program shows a red rectangle for (I suppose) the background and correctly-drawn plots but all in red. There is no text--no numbers on the axes and no labels--but this is likely due to the graphics program as is complains of missing fonts when I open the file with it. Incidentally, the curve on the lower left-hand plot appears to be too thick--about twice the thickness of the others--but this is also true of the SVG result made with e.g. x01c using either the svg or svgqt drivers. Also, those SVG files displace the data points on the upper two graphs--svgqt upwards and svt downwards, but this is perhaps for another thread. Something happened between I think versions 10303 and 10312 to cause all this red.
