[gentoo-embedded] Emerge QT

[Vincent]

Hi,

I want to compile QT in my development FS of Gentoo-embedded but I've  
some errors :
/var/tmp/portage/qt-3.3.4-r3/work/qt-x11-free-3.3.4/src/tools/

Do you have an idea to solve it ?
The /usr/include/fenv.h is missing but I think isn't a good idea to  
take /usr/include/bits/fenv.h

Thanks in advance.

Regards,

do the following changes to each file including fenv.h:
 #ifndef __UCLIBC__
 #include <fenv.h>
 #endif

and where fenv_t,fesetenv,feholdexcept are used
or alternatively port fenv.h related functions from glibc to uclibc math.
