Hi, 

I have just managed to import my current gimp cvs tree into kdevelop. It built and \
installed with surprisingly little effort. I was very impressed at how easy this was. \


I am able to run it from the debugger but if I set a break point, when it stops it \
throws a whole series of error messages like the following (one for each variable in \
the file!). 


Debugger error 
Debugger reported the following error: 
Can't take address of "row" which isn't an lvalue. 

I set the following CFLAGS from kdev: 
-O0 -march=athlon-xp -g3

also tried -g -g3 -gdb -gdb3 same results.



I am getting some things evaluated but mostly not. 

here's code imeditately refering to "rows" that was giving this particualar error. 

I have loads of similar errors at every step (often the same error repeated at every \
line even if not in that line.) 

Basically it is unusable even to step through the code without evaluation as it is. I \
need to resolve this issue. 

/* 
* non-interpolating scale_region. [adam] 
*/ 
static void 
scale_region_no_resample (PixelRegion *srcPR, 
PixelRegion *destPR) 
{ 
const gint width = destPR->w; 
const gint height = destPR->h; 
const gint orig_width = srcPR->w; 
const gint orig_height = srcPR->h; 
const gint bytes = srcPR->bytes; 
gint *x_src_offsets; 
gint *y_src_offsets; 
guchar *src; 
guchar *dest; 
gint last_src_y; 
gint row_bytes; 
gint x, y; 
gint b; 

/* the data pointers... */ 
x_src_offsets = g_new (gint, width * bytes); 
y_src_offsets = g_new (gint, height); 
src = g_new (guchar, orig_width * bytes); 
dest = g_new (guchar, width * bytes);


As a secondary issue , with all these error msgs it becomes impossible to use kdev at \
all , there are a dozen boxed to click at every step of the code. If these could be \
silenced I could at least use it to trace the code even without many of the variables \
being available.

I have rebuilt both kdev and gdb using std compiler options -march=athlon-xp -O2 \
-pipe 

Also compared to 3.3.6 and it was essentially the same.

I'm very impressed that I could import and build gimp cvs tree with kdevelop, if I \
could resolve this issue it would be imensely useful.

TIA.
