[SOLVED] crossdev fails on building gcc [--enable-esp pb]

[thild]

Hello,

I'm trying to build a cross toolchain for sparc.
I'm using crossdev-20110310 and I have tested the followings:

crossdev -t sparc-sun-linux-uclibc
crossdev -t sparc-gentoo-linux-uclibc
crossdev -t sparc-gentoo-linux-gnu
crossdev -t sparc-unknown-linux-gnu
crossdev -S -t sparc-unkown-linux-gnu
crossdev -t sparc-unknown-linux-gnu --libc 2.13 --gcc 4.5.2

All fail on building the stage1 of gcc with the same error:
configure: error: *** --enable-esp is not supported on this sparc-unknown-linux-gnu target.

Has anyone succeeded in building a cross toolchain for sparc ?

Any help will be greatly appreciated,

Thibault


P.S.:
The output of "emerge --info" on the build host:

I have also the same problem with mips64el-unknown-linux-gnu so this is not related to the sparc architecture but either to crossdev or my build host.

Does somenone have any clues about the enable-esp message from the gcc stage1 configure when using crossdev ?

OK

I have lately added the "hardened" keyword to the make.conf of my build system. I did not realize it affected crossdev at this time.
As stack protection is neither supported on sparc nor on mips64el, cross-gcc failed to build.

My fault...
