[Plib-devel] RE: Olivier's js code (LAVIGNE,ERIC), cygwin build problem

[Ima S. <ima...@ve...>]

Eric,

Thank you very much for putting this fix in.

Sorry, I said cygwin works, but it doesn't.

I am getting a build break under cygwin as shown here:

if g++ -DPACKAGE_NAME=3D\"\" -DPACKAGE_TARNAME=3D\"\" =
-DPACKAGE_VERSION=3D\"\" -DPACKAGE_STRING=3D\"\" =
-DPACKAGE_BUGREPORT=3D\"\
-DPACKAGE=3D\"plib\" -DVERSION=3D\"1.8.4\" -DSTDC_HEADERS=3D1 =
-DHAVE_SYS_TYPES_H=3D1 -DHAVE_SYS_STAT_H=3D1 -DHAVE_STDLIB_H=3D1 -DH
E_STRING_H=3D1 -DHAVE_MEMORY_H=3D1 -DHAVE_STRINGS_H=3D1 =
-DHAVE_INTTYPES_H=3D1 -DHAVE_STDINT_H=3D1 -DHAVE_UNISTD_H=3D1 =
-DWIN32=3D1  -
 -I. -I../../src/util    -g -O2 -Wall -MT jsWindows.o -MD -MP -MF =
".deps/jsWindows.Tpo" \
  -c -o jsWindows.o `test -f 'jsWindows.cxx' || echo './'`jsWindows.cxx; =
\
then mv ".deps/jsWindows.Tpo" ".deps/jsWindows.Po"; \
else rm -f ".deps/jsWindows.Tpo"; exit 1; \
fi
js.h: In function `bool getOEMProductName(jsJoystick*, char*, int)':
js.h:47: error: `int jsJoystick::error' is protected
jsWindows.cxx:46: error: within this context
js.h:45: error: `os_specific_s*jsJoystick::os' is protected
jsWindows.cxx:61: error: within this context
js.h:45: error: `os_specific_s*jsJoystick::os' is protected
jsWindows.cxx:72: error: within this context

I have updated cygwin to the latest cygwin GCC:

$ gcc --version
gcc (GCC) 3.3.3 (cygwin special)
Copyright (C) 2003 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is =
NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR =
PURPOSE.

and the problem still occurs.

I can fix the first problem by adding an accessor function in js.h like:

  int   getError      () const { return error ;    }

that is called from within jsWindows.cxx as:

  if ( joy->getError() )  return false ;

but I am not sure how to fix the other two. Can anyone please help?  Do =
non-Cygwin users on windows also see this problem?

How can we safely access os-specific protected data?  Do we need to do =
all of the getOEMProductName() os-specific processing within a =
jsJoystick class member function as is done within =
jsJoystick::jsJoystick ( int ident ) in jsLinux.cxx?

Thanks, Eric, for putting this fix in, and thanks to any C++/Cygwin =
experts that can fix it!
