I have a problem with qcc.

Following line links the the wrong libgcc.a with application:

qcc -Vgcc_ntoppcbe -Wl,-M -Wc,-msoft-float -om1 m1.c

The libggc.a in the nof directory would be the right one. If I use the
gcc frontend, the correct libgcc.a is used:
ntoppc-gcc -Wl,-M -msoft-float -om1 m1.c

Is there something wrong with my qcc commandline?

qcc doesn’t support multilib.

BTW - why are you using softfloat?

  1. Look at TicketId 61999 of standard support.
  2. I use a ppc405(cpu without fpu).

I don’t work on qcc anymore, so I can’t really comment. But I doubt that we
