Vicual C++ 6.0 and SDL_ttf

SDL Development
1

Visual C++ 6.0 seems not to recognize * always as a multiplication and it
occurs, that there is 2 times an error, where VC seems to recognize this by
a pointer operation. I changed just by adding a new line of code in both
cases and… voila no problem anymore… Was that right or is it silly, what
I did ? (I am not sure, so):

I changed the line:
src = glyph->pixmap.bitmap + row * glyph->pixmap.cols;

to

src = glyph->pixmap.bitmap;
src += row * glyph->pixmap.cols;

Now it works… stupid… isn’t it ?

I don’t believe it; not even VC++ should be that broken. Most likely something
else is wrong with your program

No, he’s referring to the fact that VC++ doesn’t allow multiplication
of void pointers.

Was this in SDL_ttf 1.2 or the experimental SDL_ttf 2.0?

Hi Sam !

I had the problem with SDL_ttf 1.2, but changing the code in 2 lines made me
get rid of the problem (errors) and changing another bit of code (i think
you left out one float cast) got me rid of the warnings… I might look it
up, where i did the changes, if needed.

regards,

sascha

neither does gcc (maybe you mean addition)

in any case, -Wpointer-arith is good to guard against accidental void
pointer arithmetic
