make check failures on debian/MIPS QEMU (Mali)

[Guhl Peter]

Hi

Well... I got ask by "make check" to report bugs... uhm... so I do ;-)
If it's not helpfull feel free to ignore.

What I really try to do is to compile a toolchain wich -msoft-fpu
because I want to create MIPS binaries able to be run on a standard
OpenWRT which happens to have FPU Kernel emulation turned off. Sounds
easy, seems to be tricky. The currently used howto is
http://nosemaj.org/debian-gcc-4-7 (which I do not follow exactly, but
mostly)

The output of make check (excerpt, but I left the last few hard
float/soft float Warnings intact... maybe that's the problem after all):
...
/usr/bin/ld: Warning: .libs/t-bdiv uses hard float, t-bdiv.o uses soft
float
/usr/bin/ld: Warning: .libs/t-bdiv uses hard float,
../../tests/.libs/libtests.a(misc.o) uses soft float
/usr/bin/ld: Warning: .libs/t-bdiv uses hard float,

gcc version 4.6.3 (Debian 4.6.3-14)

(This is the gcc which came with Debian/MIPS)

# uname -a
Linux EW-MIPS 3.2.0-4-4kc-malta #1 Debian 3.2.46-1 mips GNU/Linux

The configure command (telling you which GMP version I got too):
../../sources/gmp-5.0.4/configure --prefix=$PROJECT_DIR/output/

Well... probably this is not the latest GMP... right?

Anyway; hth.

Debian Version: 7.1

Last but not least: the QEMU start command (Windows 7): 
.\qemu-014-original\qemu-system-mips.exe -m 256 -kernel
vmlinux-3.2.0-4-4kc-malta -append "console=ttyS0 root=/dev/sda1" -hda
hda.img -localtime -net nic -net user -redir tcp:80::80 -redir
tcp:22::22

I'll continue trying to geht something working... we'll see.
