Summary 0000912: FLOAT: Can't make -- bails with error: Unknown floating point type used in --with-float=no
Description trying to compile buildroot with GCC 4.2 and ARM920T (config file attached) and getting this error every time:

checking for clock_t... yes
checking for .preinit_array/.init_array/.fini_array support... yes
checking if mkdir takes one argument... no
For real value is
For real value is
Unknown floating point type used in --with-float=no
make[1]: *** [configure-gcc] Error 1
make[1]: Leaving directory `/home/marc/buildroot/toolchain_build_arm_nofpu/gcc-4.2-initial'
make: *** [/home/marc/buildroot/toolchain_build_arm_nofpu/gcc-4.2-initial/.compiled] Error 2
Additional Information I tried adding:

ifeq ($(findstring 4.2.,$(GCC_VERSION)),4.2.)
SOFT_FLOAT_CONFIG_OPTION:=--with-float=xsoft
endif

just below the same section for "4.1" in the file buildroot/toolchain/gcc/Makefile.in but that doesn't seem to have helped anything, I'm stuck....

Can you retry with current trunk (revision 17434 or later) and let me know if this works now for gcc-4.2, latest binutils and latest kernel-headers?

Thanks,

Ping. Please update, retry and let me know if that works any better now or not.

sorry, no can do. This was part of a project using the Cirrus EP9315. Due to the total lack of support from Cirrus Logic, we switched to another processor entirely.
