pseudo-random things compiling gtk+-2.2.1 under HP-UX 11.11

[Rick Jones <rick_jones2 hp com>]

Hi -

I find myself wanting to use gtk+ for a project and so I've been working
through installing all the dependencies.

I've already run into and worked around (thanks to the archive) the
problems with atk/pango and docs not building (make failure on
all-local), and now I'm compiling gtk itself.

I'm using the HP ANSI C compiler:

$ what `which cc`
/usr/bin/cc:
        LINT B.11.11.06 CXREF B.11.11.06
        HP92453-01 B.11.11.06 HP C Compiler
         $   Sep  8 2000 23:13:51 $ 

The configure gets through OK (I had to manually move some .h files for
png/tiff into /usr/local/include) and the compile chugs along until:

cc -g -o .libs/gdk-pixbuf-csource gdk-pixbuf-csource.o  -L/usr/local/lib
-L/opt/
libpng/lib ./.libs/libgdk_pixbuf-2.0.sl /usr/local/lib/libintl.sl -lc
-Wl,+b -Wl
,/home/raj/gtk+-2.2.1/gdk-pixbuf/.libs:/usr/local/lib^M
/usr/ccs/bin/ld: (Warning) At least one PA 2.0 object file
(gdk-pixbuf-csource.o
) was detected. The linked output may not run on a PA 1.x system.^M
/usr/ccs/bin/ld: Unsatisfied symbols:^M

   g_free (code)^M
   g_object_unref (code)^M
   g_type_init (code)^M
   g_strdup (code)^M
*** Error exit code 1^M

should I have seen a glib in that cc line there somewhere? I have glib
installed on the system (libs in /usr/local/lib) and it seems that those
missing symbols are from glib.  Did I fubar something in the configure
perhaps?

What follows are the nits I've found thusfar.  The seem pretty minor.

Before the link failure, there are some warnings that come-out of the
compiler...  one is a perennial "redeclaration of macro MAX" because the
HP-UX param.h has a MAX and MIN defined.  I generally don't worry about
that and press-on but thought I might mention it anyway.

There is some stuff in timescale.c that the compiler warns about:

It looks like timescale.c is passing char* when pixops_* wants guchar

testops.c

int main (int argc, char **argv)
{
  int src_width, src_height, dest_width, dest_height;
  char *src_buf, *dest_buf;

  ...to line 184...
                    pixops_scale (dest_buf, 0, 0, dest_width,
dest_height, dest_
rowstride, dest_channels, dest_has_alpha,
                                  src_buf, src_width, src_height,
src_rowstride,
 src_channels, src_has_alpha,
                                  (double)dest_width / src_width,
(double)dest_h
eight / src_height,
                                  filter_level);

and pixops_scale:

static void

                      int            render_x0,

                      gboolean       dest_has_alpha,
                      const guchar  *src_buf,
                      int            src_width,

                      double         scale_y)

there is a redeclaration warning about gdk_pixbuf_non_anim_get_type and
gdk_pixbuf_non_anim_iter_get_type in gdk-pixbuf-animation.c

from line 567:

        static GType object_type = 0;

but above it it is forward decl'd as:

and the other is the same:


static GType gdk_pixbuf_non_anim_iter_get_type (void) G_GNUC_CONST;
...

the next set of warnings are:

The first is:

                                goto context_error;
                        pattern->prefix = g_strdup (tmp_buf->str);

 
where pattern->prefix is:

        GdkPixbufModulePattern *pattern;

and prefix is unsigned char *:

typedef struct _GdkPixbufModulePattern GdkPixbufModulePattern;
struct _GdkPixbufModulePattern {
        unsigned char *prefix;
        unsigned char *mask;
        int relevance;
};

but g_strdup returns gchar*  it is the same thing with the warning on
line 365...

which seems to be this code:

  stream = get_uint32 (stream, &pixdata->magic);
  stream = get_uint32 (stream, &pixdata->length);
  if (pixdata->magic != GDK_PIXBUF_MAGIC_NUMBER || pixdata->length <
GDK_PIXDATA

get_uint32 wants guint* as parm 2:
static inline const guint8 *
get_uint32 (const guint8 *stream, guint *result)
{

and pixdata->length is gint:

typedef struct _GdkPixdata GdkPixdata;
struct _GdkPixdata
{
  guint32 magic;        /* GDK_PIXBUF_MAGIC_NUMBER */
  gint32  length;       /* <1 to disable length checks, otherwise:
                         * GDK_PIXDATA_HEADER_LENGTH + pixel_data length
                         */
  guint32 pixdata_type; /* GdkPixdataType */
  guint32 rowstride;    /* maybe 0 to indicate non-padded data */
  guint32 width;
  guint32 height;
  guint8 *pixel_data;
};


continuing :)

And the code appears to be:

void
MODULE_ENTRY (png, fill_info) (GdkPixbufFormat *info)
{
        static GdkPixbufModulePattern signature[] = {
  905              { "\x89PNG\r\n\x1a\x0a", NULL, 100 },
                { NULL, NULL, 0 }
        };

and the GdkPixbufModulePattern

typedef struct _GdkPixbufModulePattern GdkPixbufModulePattern;
struct _GdkPixbufModulePattern {
        unsigned char *prefix;
        unsigned char *mask;
        int relevance;
};

I'm not quite sure what the compiler is complaining about there but
would _guess_ that it is the constant string being assigned to the
unsigned char *prefix?  Perhaps the compiler is being overly paranoid
about pointers to literals, which will be in the TEXT area?

The "HAVE_STDLIB_H" redefinition is a bit troubling - could it mean that
some of the dependencies arrived at different conclusions as to there
being a stdlib.h on the system?

The redeclaration warning is probably another one of those static/not
static things.  

The assignment-compatible stuff is another one of those literal vs char
* things I think:

void
MODULE_ENTRY (jpeg, fill_info) (GdkPixbufFormat *info)
{
        static GdkPixbufModulePattern signature[] = {
                { "\xff\xd8", NULL, 100 },

The line 409/410 are calls to strncmp:

                                if (!strncmp (context->block_buf,
"NETSCAPE2.0", 11) ||
                                    !strncmp (context->block_buf,
"ANIMEXTS1.0", 11)) {

where strncmp is looking for a char *, but block_buf is guchar

the warning on line 1622 is another one of those literal strings things
I think.

there are a number of other things along these lines, but this email is
long enough as it is.  if folks would like, I can provide the typescript
of the compilation.
