Compiling error when macro defined

[Vanuan]

I have a shema that includes enum values which has the same names as macro defines.

<xsd:simpleType name="ST_Example">
<xsd:restriction base="xsd:token">
  <xsd:enumeration value="macro1">
  </xsd:enumeration>
  <xsd:enumeration value="macro2">
  </xsd:enumeration>
  <xsd:enumeration value="macro3">
  </xsd:enumeration>
</xsd:restriction>
 </xsd:simpleType>

It generates to:

static const Enum MACRO1;
static const Enum MACRO2;
static const Enum MACRO3;

When compiler finds MACRO1 it substitutes it.

So, I have three options: rename name in schema rename macro write #undef MACRO1 before variable declaration.

The best option, I think, is the third. How can I change generator, so it will add "#undef MACRO1" before "static const Enum MACRO1"?

the best solution is number 2 ;) you should never give such a name to a macro. A macros should be prefixed with something like a namespace. for example our marcos have: XMLBEANSXX_ as a prefix, boost has BOOST_ log4cxx has LOG4CXX_

(microsoft macros do not count ;) )

unfortunately there is no simple possibility to change the generator, you can only change the generated code.

or there is a fourth solution: before you include you header you can undefine the marco:

#undefine MACRO1 #include "ST_example.h"

The problem is that macros is in math.h It is not prefixed with M, and fourth option doesn't help. 05.10.2011 12:34 "stawel" < [email protected]> :

surprising :)

what system are you using ? can you attach the math.h ?

probably you can add the undef at the end of the xmlbeansxx.h file.

I'm using ubuntu. Here's the snippet from math.h causing problems:

/* Types of exceptions in the `type' field.  */
# define DOMAIN     1
# define SING       2
# define OVERFLOW   3
# define UNDERFLOW  4
# define TLOSS      5
# define PLOSS      6


/* SVID mode specifies returning this large value instead of infinity.  */
# define HUGE       3.40282347e+38F

As you can see, I can't use a bunch of names as enum values in my schema.

I thought that there really is a macro called MACRO1 :)

No, it was just an example :)
