i'm trying to build a toolchain for an IXP2800(xscale) processor. The toolchain needs softfloat support and i should produce big endian binaries by default. I'm using crosstool-0.28-rc23. I've uncommented the following line in demo-arm-softfloat.sh eval `cat arm-softfloat.dat gcc-3.3.3-glibc-2.3.2.dat` sh all.sh --notest
I've modified arm-softfloat.dat the following way: KERNELCONFIG=`pwd`/arm.config TARGET=armb-softfloat-linux-gnu TARGET_CFLAGS="-O" GCC_EXTRA_CONFIG="--with-float=soft --with-cpu=xscale" GLIBC_EXTRA_CONFIG="--without-fp"
To make the toolchain big endian by default i put the following patch into $(crosstoolpath)/patches/gcc-3.3.3/: ... http://www.davehylands.com/linux/ARM-bigendian/gcc-uclibc-3.3-300-bigend.patch
The creation of the toolchains fails while running configure for the binutils:
configure: error: Unrecognized target system type; please check config.sub. make: *** [configure-bfd] error 1
I had a look at config.sub
case $basic_machine in [...] | arc | arm | arm[bl]e | arme[lb] | armv[2345] | armv[345][lb] | avr [...]
As for as i could see the target should by known.
I don't think armb matches that set of patterns. Try armbe or armeb. Also, try crosstool-0.28-rc24, it has a patch for arm bigendian glibc strlen.
You may also want to talk with the folks on the linux-arm-toolchain@lists.arm.linux.org.uk mailing list. (That's like an offshoot of the crossgcc list, but arm-linux specific.) - Dan
