nanogui: Thread: True type font

Hi,

I am trying to use Microwin with Truetype2 fonts.
I amusing the following code to create and select 
some true type fonts. The function is returning a
valid hFont. But I am not able to see any text output.
If I use some other font, then I can see messages 
like 
"Cannot find <fontname > using system font"
 and the text is displayed using system font.




HFONT       InitializeFont(char* pFontName , HDC hdc)
{
  
  LOGFONT lf;
  HFONT   hFont;
  
  memset(&lf, 0, sizeof(LOGFONT));
  strcpy(lf.lfFaceName, pFontName);

  /* lf.lfHeight = -MulDiv(12, GetDeviceCaps(hdc, LOGPIXELSY), 72);*/
  lf.lfHeight = 12;
  lf.lfWeight = FW_BOLD;
  

  hFont = CreateFontIndirect( &lf );
  
  if (NULL == hFont) return NULL;
  
  return SelectObject( hdc, hFont);
  
}

Would appreciate any help

TIA
RR

Hi All,

I use nano-X with uClinux, on a hardware based on MicroBlaze;
If I try to qualify the font “freetype”, during the compilation I obtain
this error

> client.c: In Function 'GrUnregisterInput':
> client.c:707: error: impossible constraint in 'asm'
> client.c:716: error: impossible constraint in 'asm'

Any ideas why?

Thanks.
Best Regards,
Marco

Pretty strange, a compiler bug likely.  The good news
is that you can likely comment out the entire function,
since not much uses it.

Hi Rossi,
I had also same error. By reducing optimization level it goes off say to
O0. You can compile this file separately also, with reduced optimization
level while others can go with same settings. Please try and see if it
works for you.

I have modified this settings in microwin/src/arch.rules (CFLAGS)
and also in microwin/src/makefile.rules (OPTFLAGS)  without to obtain it
turns out to you,
this setting goes inserted in some other files?

I have tried, but if comment the function the same error is introduced to me
in the successive function
and in particular to function FD_ISSET (fd, &regfdset):  that e' used me in
many points
and it did not seem the case to comment them all;

what just I do not understand is because functions FD_ISSET give problems
single
if active HAVE_FREETYPE_SUPPORT=Y
in fact the GrUnregisterInput function of the client.c always comes however
compiled.


Thanks.
