Hi!
Today I noticed that it's not a good idea to use an architecture define
as done in OpenJDK:
CPPFLAGS_COMMON = -D$(ARCH) -DARCH='"$(ARCH)"' -DLINUX $(VERSION_DEFINES) \
-D_LARGEFILE64_SOURCE -D_GNU_SOURCE -D_REENTRANT
The -D$(ARCH) e.g. on an Alpha system makes big problems because a lot
of variables are called "alpha" in GUI code.
I tried to patch the OpenJDK code in IcedTea but then I reached a point
where it's not possible to fix the issue:
/usr/include/png.h:
typedef struct png_color_8_struct
{
png_byte red; /* for use in red green blue files */
png_byte green;
png_byte blue;
png_byte gray; /* for use in grayscale files */
png_byte alpha; /* for alpha channel files */
} png_color_8;
This won't work.
Normally build systems use architecture defines as __ALPHA__ or
__alpha__ (these are also defined by the C compiler).
Any chance to get this thing changed/fixed upstream in the OpenJDK code?
As I can't think of another solution of that problem...
Probably someone decides to name a function argument "sparc"
someday... ;-)
