Hi Arjen:
Please test revision 13125 on Cygwin.
That revision changes a -debug printf specifier for size_t from %zu
(the c99 standard) to %lu for the Microsoft case as specified by the
Microsoft documentation of how size_t values must be formatted (since
they don't support %zu).
This change fixes a bug for the "MinGW Makefiles" case where the
-debug option was giving gibberish for the length of filename strings.
However, I am not sure this code will work properly on Cygwin. Does
%zu work for that platform of %lu or both? Is the WIN32 macro #defined
on Cygwin? Instead of answering those questions individually, it might
be better to simply test build-tree results on Cygwin as follows:
examples/c/x00c -dev psc -debug -o test.ps
For the MinGW/Wine case ("MinGW Makefiles" generator) I get
the following debugging output from that command:
plLoadDriver: Device not loaded!
plLoadDriver: tag=psc, drvidx=0
plLoadDriver: Trying to load ps on ps
plGetName: Maximum length of full pathname of file to be found is 116
plGetName: Full pathname of file to be found is
z:/home/wine/newstart/build_script/build_dir-1.6.1_mingw/epa_build/Source/build_plplot\data\cmap0_default.pal
plLibOpenPdfstr: Found file
z:/home/wine/newstart/build_script/build_dir-1.6.1_mingw/epa_build/Source/build_plplot\data\cmap0_default.pal
[...]
Before the bug fix that 116 was gibberish in the MinGW case since
Microsoft does not recognize the c99 %zu format specifier for size_t.
If the Cygwin build has no compiler warnings for plGetName and that
test on Cygwin also gives a reasonable number for the maximum pathname
length (normally 7 larger than the actual pathname length), then no
further fiddling has to be done with the plGetName function defined in
src/plctrl.c.
I don't think specific tests have to be done for the MSVC case since
there is no question in that case that the WIN32 macro is #defined
and the %lu format specifier used in that case should work just
like it currently does for the MinGW case.
