Description Bertrand Jacquin 2013-04-04 20:15:02 UTC

Trying to build a mips-softfloat-linux-gnu cross toolchain using crossdev failed at glibc-2.17 compilation with the given error :

configure: error: could not determine if compiler is using hard or soft floating point ABI

Full log attached

Reproducible: Always

Steps to Reproduce:
1. crossdev -t mips-softfloat-linux-gnu

Also, it work like a charm with glibc-2.16.0

what version of gcc are you using ?

post as an attachment the output of:
  mips-softfloat-linux-gnu-gcc -E -dD </dev/null - -P

> what version of gcc are you using ?

the HOST is using x86_64-pc-linux-gnu-4.6.3 (gcc version 4.6.3 (Gentoo Hardened 4.6.3 p1.11, pie-0.5.2))

I have no mips-softfloat-linux-gnu-gcc yet as gcc-stage1 is building after glibc-headers. Yeah, the bug subject is wrong

ok, that is a very different situation

should be all set now in the tree; thanks for the report!
